    Summary of the Report and Order

    1. Overview. In July 2006, the Commission adopted a Notice of Proposed Rulemaking (NPRM), Notice of Inquiry (NOI) and Order—collectively, the MedRadio NPRM. In the MedRadio NPRM, the Commission proposed to establish a new service for medical radiocommunication devices to better accommodate the varieties of new implantable and body-worn medical devices.

    2. In this Report and Order, the Commission decided to establish a new Medical Device Radio-communication Service (MedRadio Service) under part 95 of the Commission's rules. Under the rules adopted by the Commission in this Report and Order, this new service incorporates the existing Medical Implant Communications Service (MICS) “core” band at 402-405 MHz, and also includes two megahertz of newly designated spectrum in the adjacent “wing” bands at 401-402 MHz and 405-406 MHz. Thus, the MedRadio Service will provide a total of five megahertz of contiguous spectrum on a secondary basis and non-interference basis for advanced wireless medical radiocommunication devices used for diagnostic and therapeutic purposes in humans. In addition, the MedRadio Service will accommodate the operation of body-worn as well as implanted medical devices, including those using either listen-before-talk (“LBT”) frequency monitoring or non-LBT spectrum access methods, in designated portions of the 401-406 MHz band.

    3. The Commission found that the new MedRadio spectrum in the 401-402 MHz and 405-406 MHz wing bands is well suited for use on a secondary basis by the medical implant and body-worn devices covered by this Order for several reasons. First, these frequencies offer the same propagation, availability, and compatibility characteristics that were found to be favorable for the MICS in the 402-405 MHz core band. In addition, this new designation will result in a continuous span of spectrum (from 401-406 MHz) that matches the five-megahertz of spectrum that is also designated internationally for similar use by medical implant and body-worn devices.

    4. The Commission noted that the service and technical rules adopted in this Report and Order for the MedRadio Service are based upon the existing MICS rules, and include modified spectrum sharing requirements in the new wing bands. The new rules will permit the use of both medical implant devices and medical body-worn devices in specified segments of the 401-406 MHz band.

    5. The Commission found that these new MedRadio sharing rules will provide a greater degree of flexibility than is permitted by the existing medical implant rules, while also assuring spectrum use compatibility among different device types. The Commission further found that the new designation in the wing bands will provide the additional shared spectrum that is urgently needed for operation of both implant and body-worn devices. The Commission stated its further belief that the MedRadio rules adopted in this Order should encourage the continuing use of the legacy MICS core band predominantly for life-critical applications, such as those served by the existing population of medical implant devices presently used.

    6. With respect to the potential for interference to incumbent users of the 401-402 MHz and 405-406 MHz wing bands arising from the operation of MedRadio devices, the Commission concluded that the potential for such interference is negligibly small. The Commission noted that, in the United States, the 401-406 MHz band is allocated for various Federal and non-Federal uses on a primary basis, and the 402-405 MHz band is allocated for mobile, except mobile aeronautical, service on a secondary basis, with use limited to MICS. The Commission determined that, given the ultra low power limits and intermittent operating modes that will be used by these medical devices, and the expectation of large separation distances, there is little likelihood that these medical devices could cause harmful interference to incumbent operations.

    7. With respect to the potential for harmful effects to MedRadio devices due to received interference from incumbent users, the Commission observed that it would be beneficial if MedRadio devices employed robust designs. For example, the Commission noted that MedRadio medical devices—particularly those devices used for life critical and time-sensitive applications—might need to employ a variety of error detection and correction techniques, frequency monitoring capabilities, and re-transmission protocols.

    8. In broader terms, the Commission determined that the additional spectrum and enhanced flexibility afforded in the new rules will promote the accelerated development of newer generations of advanced medical device technologies. These advances, the Commission found, will herald dramatic improvements in therapeutic/diagnostic patient care and quality of life for countless individuals. The Commission also noted that the MedRadio designation and rules adopted in this Order are harmonized for the most part in their general approach with similar European Telecommunication Standards Institute (ETSI) standards relating to use of the 401-406 MHz band by medical implant and body-worn devices in other regions of the world. The Commission stated its belief that such harmonization will serve the public interest by offering Americans greater confidence of reliable device operation while traveling abroad, and conversely, by offering similar confidence for foreign visitors to the United States. The Commission also determined that economies of scale resulting from harmonized rules for domestic manufacturers seeking to compete in the world market should foster a reduction of device prices, thus making the benefits of such technologies more widely available and affordable for the American public.

    9. Licensing. Consistent with the existing MICS licensing scheme, the Commission decided that the new MedRadio service at 401-406 MHz will be governed under Part 95 of the Commission's rules, thus providing for license-by-rule operation throughout the 5 megahertz band. The Commission concluded that this approach minimizes regulatory procedures and will facilitate the more expeditious deployment of new generations of beneficial wireless medical devices in these bands that can improve the quality of life for countless Americans, thus serving the public interest, convenience and necessity. The Commission also decided that the operation of medical devices in the MedRadio band will be on a secondary, non-interference basis with respect to other authorized services and as such they must accept harmful interference from the systems operating in those services. MedRadio devices will operate on a shared, non-exclusive basis with respect to each other.

    10. Definitions—Implant and Body-worn Devices. In order to be deemed a medical body-worn device or medical body-worn transmitter, the Commission required that the antenna of the associated patient-worn device be placed upon or in very close proximity (e.g., within a few centimeters) to the body. In order to be classified as a medical implant transmitter or medical implant device, the Commission required that the transmitting antenna of the patient device must itself be implanted wholly within the body—which would include any point below the skin, or more deeply within the body. The Commission retained the Start Printed Page 22698existing definitions for medical implant devices.

    11. Authorized Frequencies for Implant and Body-Worn Devices. The Commission concluded that implanted devices will be permitted in both the existing MICS core band at 402-405 MHz, as well as in the wing bands at 401-402 MHz and 405-406 MHz. This will allow medical implant devices to operate anywhere in the 401-406 MHz band—but subject to different technical requirements in the core and wing bands.

    12. The Commission decided, with one exception, to permit body-worn devices to operate only in the wing bands at 401-402 MHz and 405-406 MHz. Thus, in the new MedRadio wing bands, both implant and body-worn devices will be allowed to operate—under common technical requirements for each—throughout both the 401-402 MHz and 405-406 MHz frequency range. The Commission stated its belief this approach will serve to accommodate a greater variety of implant and body-worn devices. The Commission also observed that, by preserving the core band at 402-405 MHz primarily for communications involving deeply implanted devices, these frequencies would likely continue to be used largely for life-critical medical devices such as cardiac defibrillators.

    13. As an exception to the general rule for body-worn devices, the Commission decided to permit the operation in the core band of temporary body-worn devices that are used to evaluate the efficacy of an implanted medical device.

    14. The Commission determined that allowing the operation of such temporary body-worn devices will enhance the therapeutic and diagnostic options available to patients. In particular, the Commission noted that this will allow physicians to better evaluate the efficacy of proposed treatments involving implanted devices prior to actual device implantation. The Commission decided to permit the operation of such temporary body-worn devices on any frequency in the 402-405 MHz core band provided that: (1) Such external operation is limited solely to evaluating with a patient the efficacy of a fully implanted permanent medical device that is intended to replace the temporary body-worn device; (2) RF transmissions from the external device must cease following the patient evaluation period, which may not exceed 30 days, except where a health care practitioner determines that additional time is necessary due to unforeseen circumstances; (3) the maximum output power of the external, temporary body-worn device shall not exceed 200 nW EIRP; and (4) the external device must comply fully with all other MedRadio rules described throughout the core 402-405 MHz band.

    15. The Commission declined to explicitly limit the core band to life-critical and time-sensitive applications, or to designate the wing bands for non-life-critical, non-time sensitive applications. The Commission said that its decision to limit the core band primarily to communications involving implanted devices, coupled with the technical rules adopted for use of the core and wing bands will achieve much the same result, while providing greater flexibility for device manufacturers and practitioners. The Commission determined that leaving the ultimate decision on these matters to health care professionals and medical device manufactures, in concert with FDA-required risk management processes, would result in better and more flexible use of this scarce spectrum resource.

    16. Permissible Communications and Operator Eligibility. The Commission concluded that the new MedRadio service will be governed by the same operator eligibility and permissible communications requirements that pertain to the legacy MICS. According to the Commission, this will result in a more beneficial use of the spectrum than alternative approaches.

    17. More specifically, the Commission decided that MedRadio devices may be used only by persons for diagnostic and therapeutic purposes, and only when provided for such purposes to a human patient under the direction of a duly authorized health care professional. Furthermore, the Commission limited the MedRadio service to the transmission of non-voice data. MedRadio programmer/control transmitters may not relay information on MedRadio frequencies to a receiver that is not included with a MedRadio device. The Commission concluded that these requirements are central to maintaining the originally intended character and utility of this spectrum, which the Commission found has proven to be of significant benefit to many patients over the years.

    18. The Commission declined to adopt rules in this Order that would permit the operation of wireless hearing aids in the upper portion of the lower MedRadio wing band. However, in recognition of the important public interest benefits associated with this proposal, the Commission welcomed additional technical submissions or revisions to address whether this or some other band(s) could accommodate various types of hearing aid devices, and stated that it would consider developing a record through a notice of proposed rulemaking to more fully analyze these matters.

    19. The Commission also declined to allow the use of MedRadio devices in connection with animal test subjects in the course of human drug research. The Commission found that such testing would not, in and of itself, directly perform any diagnostic or therapeutic function for a human patient. In contrast, the Commission observed that, since its creation, the legacy MICS had been explicitly reserved for use by devices performing diagnostic and therapeutic functions with human patients and only when such use has been duly authorized by a health care professional. It further found that changing the eligibility requirements to permit animal test subject use would constitute a major departure from these underlying requirements and that such a departure did not appear to be warranted based upon the record in this proceeding. From a procedural perspective, the Commission further stated that the MedRadio NPRM neither proposed, nor sought comment on, modifying these basic service and eligibility provisions; and that it particularly did not address the specific question at issue here of whether use of the MICS/MedRadio frequencies should be extended to animal testing. Thus, the Commission concluded that it had an insufficient substantive record or procedural notice upon which to pursue the matter of animal test subjects.

    20. MedRadio channels. The Commission decided to generally carry forward the MICS rules into the new MedRadio Service. Under the existing rules, no particular channeling scheme is specified for the operation of MICS devices. Instead, a “channel” is simply defined as any continuous segment of spectrum used by a medical device. Thus, a MedRadio device may transmit on any center frequency so long as the maximum authorized emission bandwidth is not exceeded. The Commission stated its belief that this approach is beneficial because it would continue to provide the greater flexibility that device manufacturers now use as compared with a rigid channeling scheme.

    21. Emission Bandwidth. With respect to the new MedRadio wing bands at 401-402 MHz and 405-406 MHz, the Commission concluded that a 100 kilohertz maximum authorized emission bandwidth in the limited space of the one-megahertz wide wing bands will foster more intensive spectrum utilization by a greater number of devices as compared with a 300 Start Printed Page 22699kilohertz maximum bandwidth. The Commission determined that this smaller bandwidth would allow more devices to use the wing bands on non-overlapping spectrum. In addition, the Commission found that this bandwidth will also serve to minimize interference potential from other MedRadio devices, particularly in light of the fact that both LBT and non-LBT devices will share the entire wing bands.

    22. As one exception to the general bandwidth requirement for the wing bands, the Commission decided to allow up to a 150 kilohertz maximum authorized emission bandwidth at 401.85-402 MHz. In reaching this decision, the Commission recognized that some body worn devices, such as the glucose monitoring devices that are now operating in the core band under a waiver, need a slightly wider emission bandwidth. Thus, the Commission found that its decision here to allow a slightly wider emission bandwidth at the upper edge of the 401-402 MHz wing band will facilitate transitioning such devices now operating under rule waivers out of the core band. In addition, the Commission observed that the narrower bandwidth for the wing bands, is expected to be better suited for non-life-critical devices—namely, those with less severe battery life constraints that are tailored for operation with lower bandwidth data streams utilizing a relatively greater number of longer data transmission sessions as compared with devices used in the core band.

    23. For the core band at 402-405 MHz, the Commission decided to maintain the existing maximum authorized emission bandwidth of 300 kilohertz. The Commission found that, relative to the 100 kilohertz bandwidth it adopted for the wing bands, this 300 kilohertz bandwidth will better facilitate more data-intensive transmissions of shorter duration which tend to be more energy efficient, and thus prolong battery life for implants. This will also support higher data transmission rates than could be accommodated by the maximum authorized emission bandwidth of 100 kilohertz channels of the wing bands, and thus may be more desirable for certain applications. The Commission found that such characteristics are especially beneficial in extending the battery life of deep implant devices.

    24. The Commission decided that it would continue to permit MedRadio transmitters to utilize full duplex or half duplex communications if the total amount of bandwidth used by all of the MedRadio channels employed by a MedRadio device during a MedRadio communications session does not exceed the maximum authorized emission bandwidth (i.e., 100 kilohertz in the wing bands and 300 kilohertz in the core band). Moreover, smaller bandwidths may be employed by a single MedRadio device so long as the device adheres to all other EIRP and unwanted emission limits. For example, a single MedRadio device operating in the wing bands could be designed to operate nominally on two channels, each having a maximum emission bandwidth of 50 kilohertz, because the communications session would, in aggregate, be 100 kilohertz. The Commission noted that, in essence, these provisions carry forward the existing channel use provisions of the MICS rules into the new MedRadio rules.

    25. Frequency monitoring requirement. In the Report and Order, the Commission observed the current MICS rules require that the programmer/control transmitter associated with a medical implant device in the 402-405 MHz band must incorporate a frequency monitoring mechanism to monitor the channel or channels that the medical device transmitters intend to occupy. The Commission further stated its belief that an LBT frequency monitoring requirement is beneficial because it facilitates spectrum sharing among many uncoordinated devices and can reduce the likelihood of harmful interference from federal systems that are allocated on a primary basis. Thus, the Commission decided to maintain the current frequency monitoring protocol specified in the form MICS rules as a general requirement for implant devices permitted throughout the entire 401-406 MHz MedRadio core band, as well as for body-worn devices permitted in the new wing bands. In addition, the Commission also extended the “medical implant event” exception of the current rules to LBT-enabled implant devices operating throughout the 401-406 MHz MedRadio band.

    26. In further recognition of the potential advantages of non-LBT spectrum access methods for certain low power, low duty cycle (LP-LDC) devices—particularly, in terms of extended battery life, reduced complexity, and lower device cost to patients—the Commission decided to permit the use of non-LBT spectrum access methods in the wing bands, with certain transmitter power and duty cycle limits, by both implant and body-worn devices. In addition, the Commission permitted the use of non-LBT spectrum access methods for implant devices that operate with an emission bandwidth not exceeding 300 kilohertz centered at 403.65 MHz in the existing core band with certain transmitter power and duty cycle limits. Finally, the Commission also decided to permit the operation on any of the frequencies in the 402-405 MHz band of temporary body-worn transmitting devices that are used solely during a limited patient evaluation period in order to determine the suitability of a fully implanted device, provided that they fully comply with all other MedRadio rules applicable to the band.

    27. Transmitter power and duty cycle. The Commission limited the maximum EIRP of LBT-enabled implant devices throughout the 401-406 MHz band and LBT-enabled body-worn medical devices in the wing bands to 25 microwatts EIRP. The Commission determined that, as with the original MICS rules, this limit is intended to ensure efficient spectrum sharing and compatibility among multiple uncoordinated devices. Furthermore, the 25 microwatt limit will maintain continuity with the present EIRP limit and LBT frequency monitoring requirement for the core band (which we also maintain under the new MedRadio rules) that has served well for spectrum access.

    28. With respect to access to the 402-405 MHz band by non-LBT devices, the Commission found that the convergence of comments in the record, particularly subsequent to the adoption by ETSI of similar standards, supported permitting operation by such devices with a total emission bandwidth not exceeding 300 kilohertz, centered at 403.65 MHz, with a maximum EIRP of 100 nanowatts and with maximum duty-cycle and transmission session limits of 0.01% and ten per hour, respectively. The Commission stated that its decision was informed by the increasingly widespread adoption of standards internationally that provide for non-LBT spectrum access methods in the 402-405 MHz band. Furthermore, based upon the Commission's prior experience with single-channel non-LBT devices operating under rule waivers in the core MICS band the Commission concluded that these EIRP and duty cycle limits would be sufficiently conservative to permit efficient spectrum sharing between LBT enabled and non-LBT devices that choose to operate at 403.65 MHz.

    29. For devices using non-LBT spectrum access methods in the new MedRadio wing bands at 401-402 and 405-406 MHz, the Commission adopted power and duty cycle limits that match the proposals in the MedRadio NPRM, namely a maximum EIRP of 250 nanowatts, together with a maximum Start Printed Page 22700duty cycle limit of 0.1% and a maximum limit of 100 communication sessions per hour. The Commission stated its belief that permitting the higher EIRP of 250 nanowatts for non-LBT operation in the wing bands, as compared with the 100 nanowatts adopted for non-LBT operation in the core band, will serve to encourage use of the wing bands for the majority of non-LBT applications.

    30. The Commission also recognized that some body worn devices may require higher power and greater bandwidth, such as the glucose monitoring devices manufactured by one manufacturer that are now operating in the core band under a waiver. Thus, the Commission decided to also allow non-LBT MedRadio devices using a maximum of 25 microwatts EIRP to operate at 401.85-402 MHz at the upper end of the lower wing band. The Commission determined that its decision would facilitate the transition of such devices now operating under waivers out of the core band, and into the new MedRadio wing bands. The Commission also noted that permitting the higher power and bandwidth would also provide flexibility for other manufacturers designing medical devices in these bands.

    31. Unwanted emissions. The Commission retained without modification the existing in-band and out-of-band emission limits for the MedRadio core band frequencies at 402-405 MHz. For the new MedRadio wing bands at 401-402 MHz and 405-406 MHz, the Commission adopted an emission mask having the same form as the emission mask that already exists for the core band, but modified to apply over the narrower 100 kilohertz maximum authorized emission bandwidth of the wing band. Thus, the Commission required that emissions from devices operating within the MedRadio wing bands more than 50 kilohertz away from the center frequency of a transmission be attenuated below the actual transmitter output power by at least 20 dB. In addition, it required emissions 100 kilohertz or less below 401 MHz, or above 406 MHz, to be attenuated below the maximum permitted output power by at least 20 dB. Finally, for out-of-band emissions at more than 100 kilohertz outside the 401 MHz and 406 MHz MedRadio band edges, the Commission adopted generally the same field strength limits on emissions that presently apply to the core band.

    32. The Commission declined to impose more restrictive limits on emissions from MedRadio wing band devices into the existing core band. The Commission said that under such an approach, which was recommended by one commenter, wing band devices would be burdened with more stringent limits on radiation into the core band as compared to core band devices. The Commission found no compelling reason to place wing band devices on such an unequal footing with core band devices, particularly if such a limit were to be set below the existing general emission limits contained in § 15.209 as suggested by one commenter. The Commission stated that it was confident that manufacturers of wing band devices are capable of designing their products to be compatible with and to protect core band devices, especially when both types of devices are used by the same patient. In addition, the Commission found that the emission limits it adopted would afford sufficient protection to satellite operations on frequencies below 401 MHz adjacent to the lower MedRadio wing band.

    33. RF safety and EIRP compliance. The Commission retained the basic requirements in the current rules as they apply RF safety and EIRP compliance requirements for implanted devices. In addition, the Commission decided that, to the extent feasible, body-worn MedRadio devices shall be governed by the same requirements as other hand-held transmitting devices for the purposes of demonstrating compliance with RF safety and EIRP limits.

    34. The Commission observed that it has another ongoing proceeding concerning RF exposure that would be better suited to address several other concerns expressed by some commenters. One issue involves whether and when open-area test sites or body-torso simulator measurements should be performed, and whether a 4 dB EIRP correction factor should be applied between implant and body-worn devices to account for the absorption of radio energy by body tissue that can be associated with implanted devices. A second issue involves whether unspecified “other techniques” (beyond the finite difference time domain (FDTD) technique cited in the existing rules) could be used for equipment authorization and RF exposure evaluation purposes. In view of the ongoing RF safety proceeding, the Commission declined to make any further modifications in this Report and Order.

    35. Disposition of Biotronik and DexCom Waivers. The Commission noted that it had previously granted waivers to two device manufacturers (Biotronik and DexCom) that permit the manufacture and marketing in the United States of certain models of cardiac and diabetic therapy devices that do not possess the LBT frequency monitoring capability required by the present MICS rules for the core band at 402-405 MHz. Both waivers were stated to be valid for one year from the effective date of the final MedRadio rules adopted in this proceeding.

    36. With respect to the Biotronik Waiver, the Commission found that the technical parameters of the authorized cardiac devices would now be encompassed within the provisions of the new MedRadio rules adopted herein—which provide for non-LBT operation by low power, low duty cycle implants operating between 403.5-403.8 MHz in the 402-405 MHz core band. Consequently, the Commission found that Biotronik Waiver would be rendered moot upon the effective date of the MedRadio rules adopted in this Report and Order.

    37. With respect to the DexCom Waiver, the Commission found that the covered devices did not comply with the new MedRadio rules. It thus decided to extend the waiver term for four years from the effective date of the MedRadio rules adopted herein. The Commission stated that this extended term should provide DexCom with sufficient time to come into compliance with the new MedRadio rules and to obtain the required FDA approval. The Commission also found that continued operation of the DexCom non-LBT devices in the core band, particularly at the higher power levels they use, could in the long term prove problematic for other rules-compliant devices—especially those used for life-critical applications—as the numbers of these types of devices grow. Further, the Commission also observed that the wing bands provide adequate spectrum for both LBT and non-LBT body-worn devices and that DexCom's devices may reasonably be accommodated under the new MedRadio rules for these bands. In declining to extend the waiver for 5 years as requested by DexCom, the Commission stated that it was not persuaded that the relatively small move in operating frequency, while maintaining emission bandwidth, power and duty cycle specifications, would require 5 additional years. Thus, the Commission encouraged DexCom to transition to the newly designated spectrum as soon as practicable.Start Printed Page 22701

    Final Regulatory Flexibility Analysis

    38. As required by the Regulatory Flexibility Act (RFA),[1] an Initial Regulatory Flexibility Analysis (IFRA) was incorporated in the Notice of Proposed Rulemaking and Notice of Inquiry and Order (MedRadio NPRM) in ET Docket No. 06-135.[2] The Commission sought written public comment on the proposals in the MedRadio NPRM, including comment on the IRFA. This present Final Regulatory Flexibility Analysis (FRFA) conforms to the RFA.

    A. Need for and Objectives, of the Report and Order

    39. The Report and Order establishes the Medical Device Radiocommunication Service (MedRadio) under part 95 of the Commission's rules. This new service will incorporate the existing Medical Implant Communications Service (MICS) “core” band at 402-405 MHz, and include two megahertz of newly designated spectrum in the adjacent “wing” bands at 401-402 MHz and 405-406 MHz. Altogether, the MedRadio Service will provide a total of five megahertz of contiguous spectrum for advanced wireless medical radiocommunication devices to be used for diagnostic and therapeutic purposes in humans. Among other benefits, the MedRadio Service will accommodate the operation of body-worn as well as implanted medical devices, including those using either LBT or non-LBT spectrum access methods, in designated portions of the 401-406 MHz band.

    40. Significant advances in wireless implanted and body-worn medical technologies are revolutionizing treatment for a wide variety of medical conditions and, even more fundamentally, creating new health care models serving to improve quality of life for all Americans. As demonstrated by the comment record in this proceeding, implanted and body-worn medical devices that rely upon wireless technologies are being used even today to treat a variety of cardiac and diabetic conditions. For example, wireless implanted cardiac devices serve as defibrillators and pacemakers without the need for external wired connections; while other radio-equipped devices, such as blood glucose monitors and insulin pumps, support more timely treatment for diabetic patients and allow physicians to wirelessly retrieve data and then make operating parameter adjustments with greater ease and accuracy than with the more traditional wired connection technologies. Some examples of newer generations of devices that could benefit from the use of wireless technologies include implanted vagus nerve stimulators that send electric pulses to the brain to treat severe chronic depression, and deep brain stimulators used to treat tremors related to Parkinson's disease.[3] Such advances have the potential to significantly improve the quality of life and sophistication of therapy for countless Americans living with a variety of medical conditions; and, in turn, could result in lower medical costs and extend the time between hospital visits and surgical procedures.

    B. Summary of Significant Issues Raised by Public Comments in Response to the IRFA

    41. There were no comments filed that specifically addressed the rules and policies proposed in the IFRA.

    C. Description and Estimate of the Number of Small Entities to Which the Rules Will Apply

    42. The RFA directs agencies to provide a description of and, where feasible, an estimate of the number of small entities that may be affected by the proposed rules, if adopted.[4] The RFA generally defines the term “small entity” as having the same meaning as the terms “small business,” “small organization,” and “small governmental jurisdiction.” [5] In addition, the term “small business” has the same meaning as the term “small business concern” under the Small Business Act.[6] A small business concern is one which: (1) Is independently owned and operated; (2) is not dominant in its field of operation; and (3) satisfies any additional criteria established by the SBA.[7]

    43. Nationwide, there are a total of approximately 22.4 million small businesses, according to SBA data.[8] A “small organization” is generally “any not-for-profit enterprise which is independently owned and operated and is not dominant in its field.” [9] Nationwide, as of 2002, there were approximately 1.6 million small organizations.[10] The term “small governmental jurisdiction” is defined generally as “governments of cities, towns, townships, villages, school districts, or special districts, with a population of less than fifty thousand.” [11] Census Bureau data for 2002 indicate that there were 87,525 local governmental jurisdictions in the United States.[12] We estimate that, of this total, 84,377 entities were “small governmental jurisdictions.” [13] Thus, we estimate that most governmental jurisdictions are small.

    44. Personal Radio Services. The Medical Device Radio Communications Service are being placed within part 95 of our rules (“Personal Radio Services”). Personal radio services provide short-range, low power radio for personal communications, radio signaling, and business communications not provided for in other services. The Personal Radio Services include spectrum licensed under part 95 of our rules and covers a broad range of uses.[14] Many of the licensees in these services are individuals, and thus are not small entities. In addition, due to the fact that licensing of operation under part 95 is accomplished by rule (rather than by issuance of individual license), and due to the shared nature of the spectrum utilized by some of these services, the Commission lacks direct information other than the census data above, upon which to base an estimation of the number of small entities under an SBA Start Printed Page 22702definition that might be directly affected by the proposed rules.

    45. The Commission notes, however, that the designation for the two megahertz of spectrum for the Medical Device Radio Communications Service would be limited to use by medical implant and body-worn medical devices and, thus, would not be shared with other non-Federal Governmental uses. To date, there are only a small number of manufacturers (i.e., less than ten—as few as five) that produce these devices, and FDA approval must be secured before such devices are brought to market. Due to the stringent FDA approval requirements, the small number of existing medical device manufacturers tends to focus very narrowly on this highly specialized market niche.

    46. Wireless Communications Equipment Manufacturers. The Census Bureau does not have a category specific to medical device radiocommunication manufacturing. The appropriate category is that for wireless communications equipment manufacturers. The Census Bureau defines this category as follows: “This industry comprises establishments primarily engaged in manufacturing radio and television broadcast and wireless communications equipment. Examples of products made by these establishments are: transmitting and receiving antennas, cable television equipment, GPS equipment, pagers, cellular phones, mobile communications equipment, and radio and television studio and broadcasting equipment.” The SBA has developed a small business size standard for Radio and Television Broadcasting and Wireless Communications Equipment Manufacturing, which is: all such firms having 750 or fewer employees.[15] According to Census Bureau data for 2002, there were a total of 1,041 establishments in this category that operated for the entire year. Of this total, 1,010 had employment of under 500, and an additional 13 had employment of 500 to 999. Thus, under this size standard, the majority of firms can be considered small.[16]

    47. Wireless Service Providers. The SBA has developed a small business size standard for wireless firms within the two broad economic census categories of “Paging” [17] and “Cellular and Other Wireless Telecommunications.” [18] Under both categories, the SBA deems a wireless business to be small if it has 1,500 or fewer employees. For the census category of Paging, Census Bureau data for 2002 show that there were 807 firms in this category that operated for the entire year. [19] Of this total, 804 firms had employment of 999 or fewer employees, and three firms had employment of 1,000 employees or more.[20] Thus, under this category and associated small business size standard, the majority of firms can be considered small. For the census category of Cellular and Other Wireless Telecommunications, Census Bureau data for 2002 show that there were 1,397 firms in this category that operated for the entire year.[21] Of this total, 1,378 firms had employment of 999 or fewer employees, and 19 firms had employment of 1,000 employees or more.[22] Thus, under this second category and size standard, the majority of firms can, again, be considered small.

    48. Public Safety Radio Services. Public Safety radio services include police, fire, local government, forestry conservation, highway maintenance, and emergency medical services.[23] For small businesses in this category, the above small business size standard applies to 1500 or fewer employees. There are a total of approximately 127,540 licensees in these services. Governmental entities [24] as well as private businesses comprise the licensees for these services. All governmental entities with populations of less than 50,000 fall within the definition of a small entity.[25]

    D. Description of Projected Reporting, Recordkeeping, and Other Compliance Requirements for Small Entities

    49. The Commission is using the licensing approach for the entire 401-406 MHz MedRadio band that is identical to that used for the existing MICS band at 402-405 MHz. Thus, rather than require individual transmitter licensing, the Commission authorizes operation by rule within the Citizens Band (CB) Radio Service under part 95 of our Rules and pursuant to Section 307(e) of the Communications Act.[26] Licensing will be accomplished through adherence to applicable technical standards and other operating rules (unlicensed operations). The Commission concludes that this approach is beneficial because it would minimize the administrative burden on prospective licensees as compared with an individual licensing scheme.

    E. Steps Taken To Minimize the Significant Economic Impact on Small Entities, and Significant Alternatives Considered

    50. The RFA requires an agency to describe any significant alternatives that it has considered in reaching its proposed approach, which may include the following four alternatives (among others): (1) The establishment of differing compliance or reporting requirements or timetables that take into account the resources available to small entities; (2) the clarification, consolidation, or simplification of Start Printed Page 22703compliance or reporting requirements under the rule for small entities; (3) the use of performance, rather than design, standards; and (4) an exemption from coverage of the rule, or any part thereof, for small entities.[27]

    51. In the Report and Order the Commission established a new Medical Device Radiocommunication Service (MedRadio Service) under part 95, which will encompass all medical devices permitted to operate in the 401-406 MHz band. It sought comment on the options concerning whether and how the five megahertz of spectrum that would comprise this MedRadio band could be divided among the evolving varieties of both implanted and body-worn medical transmitters, including low-power, low-duty-cycle (LPLDC) devices that do not employ “listen-before-talk” (LBT) frequency monitoring spectrum access techniques.

    52. Report to Congress: The Commission will send a copy of the Report and Order, including this FRFA, in a report to be sent to Congress pursuant to the Congressional Review Act.[28] In addition, the Commission will send a copy of the Report and Order, including this FRFA, to the Chief Counsel for Advocacy of the SBA.

    12. Section 95.628 is revised to read as follows:

    End Amendment Part
    MedRadio transmitters.

    (a) Frequency monitoring. Except as provided in (b) of this section, all MedRadio programmer/control transmitters operating in the 401-406 MHz band must operate under the control of a monitoring system that incorporates a mechanism for monitoring the channel or channels that the MedRadio system devices intend to occupy. The monitoring system antenna shall be the antenna normally used by the programmer/control transmitter for a communications session. Before the monitoring system of a MedRadio programmer/control transmitter initiates a MedRadio communications session, the following access criteria must be met:

    (1) The monitoring system bandwidth measured at its 20 dB down points must be equal to or greater than the emission bandwidth of the intended transmission.

    (2) Within 5 seconds prior to initiating a communications session, circuitry associated with a MedRadio programmer/control transmitter must monitor the channel or channels the system devices intend to occupy for a minimum of 10 milliseconds per channel.

    (3) Based on use of an isotropic monitoring system antenna, the monitoring threshold power level must not be more than 10logB(Hz) −150 (dBm/Hz) + G(dBi), where B is the emission bandwidth of the MedRadio communications session transmitter having the widest emission and G is the MedRadio programmer/control transmitter monitoring system antenna gain relative to an isotropic antenna. For purposes of showing compliance with the above provision, the above calculated threshold power level must be increased or decreased by an amount equal to the monitoring system antenna gain above or below the gain of an isotropic antenna, respectively.

    (4) If no signal in a MedRadio channel above the monitoring threshold power level is detected, the MedRadio programmer/control transmitter may initiate a MedRadio communications session involving transmissions to and from a medical implant or medical body-worn device on that channel. The MedRadio communications session may continue as long as any silent period between consecutive data transmission bursts does not exceed 5 seconds. If a channel meeting the criteria in paragraph (a)(3) of this section is unavailable, the channel with the lowest ambient power level may be accessed.

    (5) When a channel is selected prior to a MedRadio communications session, it is permissible to select an alternate channel for use if communications are interrupted, provided that the alternate channel selected is the next best choice using the above criteria. The alternate channel may be accessed in the event a communications session is interrupted by interference. The following criteria must be met:

    (i) Before transmitting on the alternate channel, the channel must be monitored for a period of at least 10 milliseconds.

    (ii) The detected power level during this 10 millisecond or greater monitoring period must be no higher than 6dB above the power level detected when the channel was chosen as the alternate channel.

    (iii) In the event that this alternate channel provision is not used by the MedRadio system or if the criteria in paragraphs (a)(5)(i) and (ii) are not met, a channel must be selected using the access criteria specified in paragraphs (a)(1) through (a)(4) of this section.

    (6) As used in this section, the following definitions apply:

    (i) Emission bandwidth— Measured as the width of the signal between the points on either side of carrier center frequency that are 20 dB down relative to the maximum level of the modulated carrier. Compliance will be determined using instrumentation employing a peak detector function and a resolution bandwidth approximately equal to 1% of the emission bandwidth of the device under test.

    (ii) MedRadio channel—Any continuous segment of spectrum in the MedRadio band that is equal to the Start Printed Page 22706emission bandwidth of the device with the largest bandwidth that is to participate in a MedRadio communications session.

    Note to paragraph (a)(6)(ii): The rules do not specify a channeling scheme for use by MedRadio systems.

    (iii) MedRadio communications session—A collection of transmissions, that may or may not be continuous, between MedRadio system devices.

    (b) Exceptions to frequency monitoring criteria. MedRadio devices or communications sessions that meet any one of the following criteria are not required to use the access criteria set forth in paragraph (a) of this section:

    (1) MedRadio communications sessions initiated by a medical implant event.

    (2) MedRadio devices operating in either the 401-401.85 MHz or 405-406 MHz bands, provided that the transmit power is not greater than 250 nanowatts EIRP and the duty cycle for such transmissions does not exceed 0.1%, based on the total transmission time during a one-hour interval.

    (3) MedRadio devices operating in the 401.85-402 MHz band, provided that the transmit power is not greater than 25 microwatts EIRP and the duty cycle for such transmissions does not exceed 0.1%, based on the total transmission time during a one-hour interval.

    (4) MedRadio devices operating with a total emission bandwidth not exceeding 300 kHz centered at 403.65 MHz, provided that the transmit power is not greater than 100 nanowatts EIRP and the duty cycle for such transmissions does not exceed 0.01%, based on the total transmission time during a one-hour interval.

    (c) Operating frequency. MedRadio stations authorized under this part may operate on frequencies in the 401-406 MHz band as follows provided that the out-of-band emissions are attenuated in accordance with § 95.635:

    (1) MedRadio stations associated with medical implant devices, which incorporate a frequency monitoring system as set forth in paragraph (a) of this section, may operate on any of the frequencies in the 401-406 MHz band.

    (2) MedRadio stations associated with medical implant devices, which do not incorporate a frequency monitoring system as set forth in paragraph (a) of this section, may operate on any frequency in 401-402 MHz or 405-406 MHz bands, or at 403.65 MHz in the 402-405 MHz band.

    (3) MedRadio stations associated with medical body-worn devices, regardless of whether a frequency monitoring system as set forth in paragraph (a) of this section is employed, may operate on any of the frequencies in the 401-402 MHz or 405-406 MHz bands.

    (4) MedRadio stations that are used externally to evaluate the efficacy of a more permanent medical implant device, regardless of whether a frequency monitoring system as set forth in paragraph (a) of this section is employed, may operate on any of the frequencies in the 402-405 MHz band, provided that:

    (i) Such external body-worn operation is limited solely to evaluating with a patient the efficacy of a fully implanted permanent medical device that is intended to replace the temporary body-worn device;

    (ii) RF transmissions from the external device must cease following the patient evaluation period, which may not exceed 30 days, except where a health care practitioner determines that additional time is necessary due to unforeseen circumstances;

    (iii) The maximum output power of the temporary body-worn device shall not exceed 200 nW EIRP; and

    (iv) The temporary body-worn device must comply fully with all other MedRadio rules applicable to medical implant device operation in the 402-405 MHz band.

    (d) Authorized bandwidth. The authorized bandwidth of the emission from a MedRadio station operating between 402-405 MHz shall not exceed 300 kHz, and no communications session involving MedRadio stations shall use more than a total of 300 kHz of bandwidth during such a session. The authorized bandwidth of the emission from a MedRadio station operating between 401-401.85 MHz or 405-406 MHz shall not exceed 100 kHz, and no communications session involving MedRadio stations shall use more than a total of 100 kHz of bandwidth during such a session. The authorized bandwidth of the emission from a MedRadio station operating between 401.85-402 MHz shall not exceed 150 kHz, and no communications session involving MedRadio stations shall use more than a total of 150 kHz of bandwidth during such a session.

    Note to paragraph (d): This provision does not preclude full duplex or half duplex communications provided that the total amount of bandwidth utilized by all of the MedRadio channels employed in such a MedRadio communications session does not exceed 300 kHz in the 402-405 MHz band, or 100 kHz in the 401-402 MHz and 405-406 MHz bands.

    (e) Frequency stability. Each transmitter in the MedRadio service must maintain a frequency stability of ±100 ppm of the operating frequency over the range:

    (1) 25° C to 45° C in the case of medical implant transmitters; and

    (2) 0° C to 55° C in the case of MedRadio programmer/control transmitters and MedRadio body-worn transmitters.

    (f) Shared access. The provisions of this section shall not be used to extend the range of spectrum occupied over space or time for the purpose of denying fair access to spectrum for other MedRadio systems.

    (g) Measurement procedures. (1) MedRadio transmitters shall be tested for frequency stability, radiated emissions and EIRP limit compliance in accordance with paragraphs (g)(2) and (g)(3) of this section.

    (2) Frequency stability testing shall be performed over the temperature range set forth in (e) of this section.

    (3) Radiated emissions and EIRP limit measurements limit may be determined by measuring the radiated field from the equipment under test at 3 meters and calculating the EIRP. The equivalent radiated field strength at 3 meters for 25 microwatts, 250 nanowatts, and 100 nanowatts EIRP is 18.2, 1.8, or 1.2 mV/meter, respectively, when measured on an open area test site; or 9.1, 0.9, or 0.6 mV/meter, respectively, when measured on a test site equivalent to free space such as a fully anechoic test chamber. Power measurements for transmissions by stations authorized under this section may be made either in accordance with a Commission-approved peak power technique, or the following. Peak transmit power must be measured over any interval of continuous transmission using instrumentation calibrated in terms of an rms-equivalent voltage. The measurement results shall be properly adjusted for any instrument limitations, such as detector response times, limited resolution bandwidth capability when compared to the emission bandwidth, sensitivity, etc., so as to obtain a true peak measurement for the emission in question over the full bandwidth of the channel.

    (i) For a transmitter intended to be implanted in a human body, radiated emissions and EIRP measurements for transmissions by stations authorized under this section may be made in accordance with a Commission-approved human body simulator and test technique. A formula for a suitable tissue substitute material is defined in OET Bulletin 65 Supplement C (01-01).

    (2) Lesser emission bandwidths may be employed, provided that the unwanted emissions are attenuated as provided in § 95.635. See §§ 95.628(g) and 95.639(f) regarding maximum transmitter power and measurement procedures.

    (3) Emission bandwidth will be determined by measuring the width of the signal between points, one below the carrier center frequency and one above the carrier center frequency, that are 20 dB down relative to the maximum level of the modulated carrier. Compliance with the emission bandwidth limit is based on the use of measurement instrumentation employing a peak detector function with an instrument resolution bandwidth approximately equal to 1.0 percent of the emission bandwidth of the device under measurement.

    (6) Emissions from a MedRadio transmitter operating in the 401-402 MHz or 405-406 MHz bands that are more than 100 kHz outside of either the 401-402 MHz or 405-406 MHz bands, and all emissions from such transmitter in the band 406.000-406.100 MHz shall be attenuated to a level no greater than the following field strength limits:

    Frequency (MHz)Field strength (μV/m)Measurement distance (m)
    30-881003
    88-2161503
    216-9602003
    960 and above5003
    Note—At band edges, the tighter limit applies.

    (7) The emission limits shown in paragraph (d)(6) are based on measurements employing a CISPR quasi-peak detector except that above 1 GHz, the limit is based on measurements employing an average detector. Measurements above 1 GHz shall be performed using a minimum resolution bandwidth of 1 MHz. See also § 95.605.

    (8) The emissions from a MedRadio transmitter operating in the MedRadio bands (between 401-402 MHz or 405-406 MHz) must be measured to at least the tenth harmonic of the highest fundamental frequency designed to be emitted by the transmitter.

    (9) Emissions between 401-401.85 MHz or 405-406 MHz within the MedRadio bands that are more than 50 kHz away from the center frequency of the spectrum the transmission is intended to occupy (or more than 75 kHz away from the center frequency of MedRadio transmitters operating between 401.85-402 MHz) shall be attenuated below the transmitter output power by at least 20 dB. Compliance with this limit is based on the use of measurement instrumentation employing a peak detector function with an instrument resolution bandwidth approximately equal to 1.0 percent of the emission bandwidth of the device under measurement.

    (10) Emissions 100 kHz or less below 401 MHz or above 406 MHz shall be attenuated below the maximum permitted output power by at least 20 dB. Compliance with this limit is based on the use of measurement instrumentation employing a peak detector function with an instrument resolution bandwidth approximately equal to 1.0 percent of the emission bandwidth of the device under measurement.

    Subpart I—Medical Device Radiocommunication Service (MedRadio)

    Eligibility.

    Operation in the MedRadio service is permitted by rule and without an individual license issued by the FCC. Duly authorized health care professionals are permitted to operate MedRadio transmitters. Persons may also operate MedRadio transmitters to the extent the transmitters are incorporated into implanted or body-worn medical devices that are used by the person at the direction of a duly authorized health care professional; this includes medical devices that have been implanted in that person or placed on the body of that person by or under the direction of a duly authorized health care professional. Manufacturers of medical devices that include MedRadio transmitters, and their representatives, are authorized to operate transmitters in this service for the purpose of demonstrating such equipment to duly authorized health care professionals. No entity that is a foreign government or which is acting in its capacity as a representative of a foreign government is eligible to operate a MedRadio transmitter. The term “duly authorized health care professional” means a physician or other individual authorized under state or federal law to provide health care services. Operations that comply with the requirements of this part may be conducted under manual or automatic control.

    Authorized locations.

    MedRadio operation is authorized anywhere CB station operation is authorized under § 95.405.

    Station identification.

    A station is not required to transmit a station identification announcement.

    Station inspection.

    Any non-implanted MedRadio transmitter must be made available for inspection upon request by an authorized FCC representative. Persons operating implanted or body-worn MedRadio transmitters shall cooperate reasonably with duly authorized FCC representatives in the resolution of interference.

    Permissible communications.

    (a) Except for the purposes of testing and for demonstrations to health care professionals, MedRadio programmer/control transmitters may transmit only non-voice data containing operational, diagnostic and therapeutic information associated with a medical implant device or medical body-worn device that has been implanted or placed on the person by or under the direction of a duly authorized health care professional.

    (b) Except as provided in § 95.628(b) no MedRadio implant or body-worn transmitter shall transmit except in response to a transmission from a MedRadio programmer/control transmitter or in response to a non-radio frequency actuation signal generated by a device external to the body with respect to which the MedRadio implant or body-worn transmitter is used.

    (c) MedRadio programmer/control transmitters may be interconnected with other telecommunications systems including the public switched telephone network.

    (d) For the purpose of facilitating MedRadio system operation during a MedRadio communications session, as defined in § 95.628, MedRadio transmitters may transmit in accordance with the provisions of § 95.628(a) for no more than 5 seconds without the communications of data; MedRadio transmitters may transmit in accordance with the provisions of § 95.628(b)(3) for no more than 3.6 seconds in total within a one-hour time period without the communications of data; MedRadio transmitters may transmit in accordance with the provisions of § 95.628(b)(2) for no more than 360 milliseconds in total within a one-hour time period without the communications of data.

    (e) MedRadio programmer/control transmitters may not be used to relay information to a receiver that is not included with a medical implant or medical body-worn device. Wireless retransmission of information intended to be transmitted by a MedRadio programmer/control transmitter or information received from a medical implant or medical body-worn transmitter shall be performed using other radio services that operate in spectrum outside of the MedRadio band.

    Channel use policy.

    (a) The channels authorized for MedRadio operation by this part of the FCC Rules are available on a shared basis only and will not be assigned for the exclusive use of any entity.

    (b) To reduce interference and make the most effective use of the authorized facilities, MedRadio transmitters must share the spectrum in accordance with § 95.628.

    (c) MedRadio operation is subject to the condition that no harmful interference is caused to stations operating in the 400.150-406.000 MHz band in the Meteorological Aids, Meteorological Satellite, or Earth Exploration Satellite Services. MedRadio stations must accept any interference from stations operating in the 400.150-406.000 MHz band in the Meteorological Aids, Meterological Satellite, or Earth Exploration Satellite Services.

    Antennas.

    No antenna for a MedRadio transmitter shall be configured for permanent outdoor use. In addition, any MedRadio antenna used outdoors shall not be affixed to any structure for which the height to the tip of the antenna will exceed three (3) meters (9.8 feet) above ground.

    Disclosure policies.

    Manufacturers of MedRadio transmitters must include with each transmitting device the following statement:

    “This transmitter is authorized by rule under the Medical Device Radiocommunication Service (in part 95 of the FCC Rules) and must not cause harmful interference to stations operating in the 400.150-406.000 MHz band in the Meteorological Aids (i.e., transmitters and receivers used to communicate weather data), the Meteorological Satellite, or the Earth Exploration Satellite Services and must accept interference that may be caused by such stations, including interference that may cause undesired operation. This transmitter shall be used only in accordance with the FCC Rules governing the Medical Device Radiocommunication Service.
