Summary of Report and Order
The Commission has released a Report and Order that (a) amends the
Table of Frequency Allocations in Sec. 2.106 of the Commission's Rules;
(b) allocates the 402-405 MHz band on a shared basis and designates
this shared allocation for use by the MICS; and (c) revises part 95 of
the Commission's Rules to permit the operation of ultra-low power MICS
transmitters in the 402-405 MHz band without an individual license
issued by the Commission.
The 402-405 MHz band was selected because it is suitable for
propagation of radio signals within the human body, and is available
internationally for medical implant use. Sharing the band with the
Meteorological Aids Service is feasible because of the low power and
duty cycle of MICS transmitters. In order to insure compliance with the
technical standards, the rules require certification of MICS
transmitters, but the Commission did not adopt its proposal to require
registration of transmitting equipment with the manufacturer.
Administrative Matters
Final Regulatory Flexibility Analysis (FRFA)
1. As required by the Regulatory Flexibility Act (RFA), an Initial
Regulatory Flexibility Analysis (IRFA) was incorporated in the Notice
prepared in this proceeding. The Commission sought written public
comment on the proposals in the Notice, including comments on the IRFA.
This present FRFA conforms to the RFA.
A. Need for, and Objectives of, the Report and Order
2. In this proceeding, we amend parts 1, 2 and 95 of the
Commission's Rules to establish the Medical Implant Communications
Service (MICS) as a shared allocation in the Non-Government 402-405 MHz
band, and to codify the service rules for the MICS. The adopted rules
will permit the use of newly-developed, life-saving medical technology
without causing interference to other users of the frequency band.
B. Summary of Significant Issues Raised by Public Comments in Response
to the IRFA
3. No comments were submitted specifically in response to the IRFA.
C. Description and Estimate of the Number of Small Entities to Which
the Adopted Rules Will Apply
4. 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. The RFA generally defines
the term ``small entity'' as having the same meaning as the terms
``small business,'' ``small organization,'' and ``small governmental
jurisdiction.'' In addition, the term ``small business'' has the same
meaning as the term ``small business concern'' under the Small Business
Act. 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 Small Business
Administration (SBA). A small organization is generally ``any not-for-
profit enterprise which is independently owned and operated and is not
dominant in its field.'' Nationwide, as of 1992, there were
approximately 275,801 small organizations. ``Small governmental
jurisdiction'' generally means ``governments of cities, counties,
towns, townships, villages, school districts, or special districts,
with a population of less than 50,000.'' As of 1992, there were
approximately 85,006 governmental jurisdictions in the United States.
This number includes 38,978 counties, cities, and towns; of these,
37,566, or 96 percent, have populations of fewer than 50,000. The
Census Bureau estimates that this ratio is approximately accurate for
all governmental entities. Thus, of the 85,006 governmental entities,
we estimate that 81,600 (96 percent) are small entities. Of the
estimated 81,600 small governmental entities, many are hospital and
health care facilities.
5. In addition, the adopted rules would apply to manufacturers of
medical implant devices and users of the proposed MICS equipment, such
as hospitals and clinics that are not government health care
facilities. According to the SBA's regulations, nursing homes and
hospitals must have annual gross receipts of $5 million or less in
order to qualify as a small business concern. There are approximately
11,471 nursing care firms in the nation, of which 7,953 have annual
gross receipts of $5 million or less. There are approximately 3,856
hospital firms in the nation, of which 294 have gross receipts of $5
million or less. We do not know how many hospitals would actually
implement MICS equipment; however, the maximum number of facilities to
which the adopted rules would apply is 8,247.
D. Description of Projected Reporting, Recordkeeping and Other
Compliance Requirements
6. There is a reporting or recordkeeping requirement that will be
imposed as a result of the actions adopted in this rule making
proceeding. Manufacturers of medical implant programmer/control
transmitters will continue to be required to follow our normal
equipment authorization procedures, and include with each transmitting
device a statement regarding harmful interference pursuant to
Secs. 95.1215(a) and 95.1217 of the Rules.
E. Steps Taken to Minimize Significant Economic Impact on Small
Entities and Significant Alternatives Considered
7. By making frequency spectrum available, the adopted rules will
have a beneficial economic impact on small business entities that would
either manufacture, or contribute to the manufacturing of, equipment
used in the MICS by enabling these businesses to increase their product
lines. In addition, a beneficial, indirect, economic impact affects
individuals who are the recipients of implanted MICS devices. While a
precise determination of the cost savings is difficult to calculate,
two examples are useful. First, over $15 million per year would be
saved by eliminating the need to conduct quarterly interrogation of
implanted cardiac defibrillators in the clinical setting. This estimate
does not include the interrogation of pacemakers, which are implanted
at a much higher
[[Page 69928]]
rate than defibrillators. Second, over $37 billion is currently spent
annually on hospitalization due to heart failure. When devices
currently under development for the management of heart failure
incorporate the MICS technology, it is expected that there will be a
meaningful reduction in hospitalization costs. Assuming this impact is
as small as five percent, the estimated savings would be nearly $2
billion per year.
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 Small Business Regulatory Enforcement Fairness Act of
1996, see 5 U.S.C. 801(a)(1)(A). In addition, the Commisson will send a
copy of the Report and Order, including FRFA to the Chief Counsel for
Advocacy of the Small Business Administration. A copy of the Report and
Order and FRFA (or summaries thereof) will also be published in the
Federal Register. See 5 U.S.C. 604(b).

a grant of equipment authorization only for the personal use of the
person in whom the medical implant transmitter has been inserted.
PART 95--PERSONAL RADIO SERVICES
6. The authority for part 95 continues to read as follows:
Authority: Secs. 4, 303, 48 Stat. 1066, 1082, as amended; 47
U.S.C. 154, 303.
7. Section 95.401 is amended by adding paragraph (d) to read as
follows:
Sec. 95.401 (CB Rule 1) What are the Citizens Band Radio Services?
* * * * *
(d) The Medical Implant Communications Service (MICS)--an ultra-low
power radio service for the transmission of non-voice data for the
purpose of facilitating diagnostic and/or therapeutic functions
involving implanted medical devices. The rules for this service are
contained in subpart I of this part.
8. Section 95.601 is amended by revising the last sentence in the
undesignated text to read as follows:
Sec. 95.601 Basis and purpose.
* * * The Personal Radio Services are the GMRS (General Mobile
Radio Service)--subpart A, the Family Radio Service (FRS)--subpart B,
the R/C (Radio Control Radio Service)--subpart C, the CB (Citizens Band
Radio Service)--subpart D, the Low Power Radio Service (LPRS)--subpart
G, and the Medical Implant Communications Service (MICS)--subpart I.
9. Section 95.603 is amended by adding paragraph (f) to read as
follows:
Sec. 95.603 Certification required.
* * * * *
(f) Each Medical Implant Communications Service transmitter (a
transmitter that operates or is intended to operate in the MICS) must
be certificated except for medical implant transmitters that are not
marketed for use in the United States, but which otherwise comply with
the MICS technical requirements and are operated in the United States
by individuals who have traveled to the United States from abroad.
Medical implant transmitters (as defined in Appendix 1 to subpart E of
part 95 of this chapter) are subject to the
[[Page 69930]]
radiofrequency radiation exposure requirements specified in
Secs. 1.1307 and 2.1093 of this chapter, as appropriate. Applications
for equipment authorization of devices operating under this section
must contain a finite difference time domain (FDTD) computational
modeling report showing compliance with these provisions for
fundamental emissions. The Commission retains the discretion to request
the submission of specific absorption rate measurement data.
10. Section 95.605 is amended by revising the first paragraph of
the undesignated text to read as follows:
Sec. 95.605 Certification procedures.
Any entity may request certification for its transmitter when the
transmitter is used in the GMRS, R/C, CB, IVDS, LPRS, or MICS following
the procedures in part 2 of this chapter. Medical implant transmitters
shall be tested for emissions and EIRP limit compliance while enclosed
in a medium that simulates human body tissue in accordance with the
procedures in Sec. 95.639(g). Frequency stability testing for MICS
transmitters shall be performed over the temperature range set forth in
Sec. 95.628.
* * * * *
11. Section 95.628 is added to read as follows:
Sec. 95.628 MICS Transmitter.
(a) Frequency monitoring. Medical implant programmer/control
transmitters must incorporate a mechanism for monitoring the channel or
channels that the MICS 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 a medical
implant programmer/control transmitter initiates a MICS 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 medical implant programmer/control
transmitter must monitor the channel or channels the MICS 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 MICS
communication session transmitter having the widest emission and G is
the medical implant 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 MICS channel above the monitoring threshold
power level is detected, the medical implant programmer/control
transmitter may initiate a MICS communications session involving
transmissions to and from a medical implant device on that channel. The
MICS 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 MICS communications
session, it is permissible to select an alternate channel for use if
communications is 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 6 dB 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 MICS system or if the criteria in (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) MICS channel--Any continuous segment of spectrum that is equal
to the emission bandwidth of the device with the largest bandwidth that
is to participate in a MICS communications session. (Note: The rules do
not specify a channeling scheme for use by MICS systems.)
(iii) MICS communications session--A collection of transmissions,
that may or may not be continuous, between MICS system devices.
(b) MICS communications sessions initiated by a medical implant
event are not required to use the access criteria set forth in
paragraph (a) of this section.
(c) Stations may operate on any of the frequencies in the band 402-
405 MHz, provided that the out-of-band emissions are attenuated in
accordance with Sec. 95.635.
(d) The authorized bandwidth of the emission from a MICS station
shall not exceed 300 kHz, and no communications session involving MICS
stations shall use more than a total of 300 kHz of bandwidth during
such a session. Note: This provision does not preclude full duplex or
half duplex communications provided that the total amount of bandwidth
utilized by all of the MICS channels employed in such a MICS
communications session does not exceed 300 kHz.
(e) Each transmitter in the MICS service must maintain a frequency
stability of +/-100 ppm of the operating frequency over the range:
(1) 25 deg.C to 45 deg.C in the case of medical implant
transmitters; and
(2) 0 deg.C to 55 deg.C in the case of medical implant programmer/
control transmitters.
(f) The provisions of this section shall not be used to extend the
range of spectrum occupied over space or time for the purpose denying
fair access to spectrum for other MICS systems.
12. Section 95.631 is amended by adding paragraph (h) to read as
follows:
Sec. 95.631 Emission types.
* * * * *
(h) A MICS station may transmit any emission type appropriate for
communications in this service. Voice communications, however, are
prohibited.
13. Section 95.633 is amended by adding paragraph (e) to read as
follows:
Sec. 95.633 Emission bandwidth.
* * * * *
(e) For transmitters in the MICS:
(1) The maximum authorized emission bandwidth is 300 kHz.
(2) Lesser authorized emission bandwidths may be employed, provided
that the unwanted emissions are
[[Page 69931]]
attenuated as provided in Sec. 95.635 and that the power radiated in
any 300 kHz bandwidth does not exceed 25 microwatts EIRP. See
Secs. 95.605 and 95.639(g) regarding power measurement procedures.
(3) Emission bandwidth will be determined by measuring the width of
the signal between two 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.
14. Section 95.635 is amended by revising paragraph (b) and adding
paragraph (d) to read as follows:
Sec. 95.635 Unwanted radiation.
* * * * *
(b) The power of each unwanted emission shall be less than TP as
specified in the applicable paragraphs listed in the following table:

(d) For transmitters designed to operate in the MICS, emissions
shall be attenuated in accordance with the following:
(1) Emissions more than 250 kHz outside of the MICS band (402-405
MHz) shall be attenuated to a level no greater than the following field
strength limits:
------------------------------------------------------------------------
Field
strength Measurement
Frequency (MHz) (V/ distance
m) (m)
------------------------------------------------------------------------
30-88........................................ 100 3
88-216....................................... 150 3
216-960...................................... 200 3
960 and above................................ 500 3
------------------------------------------------------------------------
Note--At band edges, the tighter limit applies.
(2) The emission limits shown in the above table 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 Sec. 95.605.
(3) The emissions from a MICS transmitter must be measured to at
least the tenth harmonic of the highest
[[Page 69932]]
fundamental frequency designed to be emitted by the transmitter.
(4) Emissions within the MICS band (402-405 MHz) more than 150 kHz
away from the center frequency of the spectrum the transmission is
intended to occupy, will 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.
(5) Emissions 250 kHz or less that are above and below the MICS
band (402-405 MHz) will 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.
15. Section 95.639 is amended by adding paragraph (f) to read as
follows:
Sec. 95.639 Maximum transmitter power.
* * * * *
(f) In the MICS the following limits apply:
(1) The maximum EIRP for MICS transmitter stations is 25
microwatts. The antenna associated with any MICS transmitter must be
supplied with the transmitter and shall be considered part of the
transmitter subject to equipment authorization. Compliance of any MICS
transmitter with the 25 microwatts EIRP 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 EIRP is 18.2 mV/meter when measured on an open
area test site, or 9.1 mV/meter when measured on a test site equivalent
to free space such as a fully anechoic test chamber. In either case,
compliance is based on measurements using a peak detector function and
measured over an interval of time when transmission is continuous and
at its maximum power level. In lieu of using a peak detector function,
instrumentation techniques set forth in ANSI C63.17-1998, Section
6.1.2.2.1 or Section 6.1.2.2.2 may be used in determining compliance
with the above specifications.
(2) For a transmitter intended to be implanted in a human body, the
following test fixture must be used to simulate operation of the
implant under actual operating conditions. See Sec. 95.605.
(i) For measurement purposes to determine compliance with emission
limits, the radiating characteristics of an implant transmitter placed
in a test fixture should approximate those of an implant transmitter
placed in a human body. An appropriate human torso simulator for
testing medical implant transmitters consists of a cylindrical
Plexiglas container with a size of 30 cm by 76 cm with a sidewall
thickness of 0.635 cm. It must be completely filled with a material
that is sufficiently fluidic that it will flow around the implant
without any voids. The dielectric and conductivity properties of this
material must match the dielectric and conductivity properties of human
muscle tissue at 403.5 MHz. All emissions measurements will be made
using the above specification at a nominal temperature of 20-25 deg.C.
Simple saline solutions do not meet the above criteria. A mounting grid
for the implant inside the container must be provided that permits the
radiating element or elements of the implant to be positioned
vertically and horizontally. The grid should also support any
additional implant leads associated with the therapeutic function in a
fixed repeatable manner. The implant must be mounted 6 cm from the
sidewall and centered vertically within the container. The above
fixture shall be placed on a turntable such that the implant
transmitter will be located at a nominal 1.5-meter height above ground
and at a 3-meter distance from the measurement antenna. Radiated
emissions measurements shall then be performed to insure compliance
with the applicable technical specifications.
(ii) A formula for a suitable tissue substitute material is defined
in the paper ``Simulated Biological Materials for Electromagnetic
Radiation Absorption Studies'' by G. Hartsgrove, A. Kraszewski, and A.
Surowiec as published in ``Bioelectromagnetics 8:29-36 (1987)''.
(3) The power radiated in any 300 kHz bandwidth shall not exceed 25
microwatts EIRP. See Secs. 95.633(e) and 95.639(g).
16. Section 95.649 is revised to read as follows:
Sec. 95.649 Power capability.
No FRS, R/C, CB, LPRS, or MICS transmitter shall incorporate
provisions for increasing its transmitter power to any level in excess
of the limits specified in Sec. 95.639.
17. Section 95.651 is revised to read as follows:
Sec. 95.651 Crystal control required.
All transmitters used in the Personal Radio Services must be
crystal controlled, except an R/C station that transmits in the 26-27
MHz frequency band, a FRS unit, a LPRS unit, or a MICS transmitter.
