    ACTION: Final rule; petition for reconsideration.
    
    -----------------------------------------------------------------------
    
    SUMMARY: The Commission has adopted a Memorandum Opinion and Order 
    (MO&O) which addresses issues and concerns raised in twenty-four 
    petitions, five oppositions, and three replies, requesting that we 
    reconsider or clarify various decisions and technical rules adopted in 
    the Report and Order (R&O) in PR Docket No. 92-235. This MO&O also 
    addresses a petition for reconsideration filed in PR Docket No. 92-257 
    regarding the shared use of industrial/land transportation and maritime 
    public correspondence frequencies. Consistent with our objective of 
    increasing the efficiency of the PLMR frequency bands this MO&O 
    clarifies our decisions in the R&O, and where necessary, makes 
    appropriate modifications to the rules. This MO&O maintains the channel 
    plan adopted in the R&O, but also permits frequency coordinators to 
    recommend frequencies for any technology with lesser bandwidth, 
    provided that interference is not caused to other systems. 
    Additionally, the Commission extends the first transition date for the 
    type acceptance of narrowband equipment from August 1, 1996, to 
    February 14, 1997, and retains the second transition date of January 1, 
    2005. Further, the Commission clarifies the rules regarding type 
    acceptance to provide greater flexibility for manufacturers to support 
    existing equipment and, where appropriate, to provide alternatives to 
    our efficiency standards. Finally, the Commission clarifies a variety 
    of technical rules including, but not limited to, those pertaining to 
    new power/antenna height limits, the emission mask, and frequency 
    stability requirements.
    
    EFFECTIVE DATE: February 14, 1997.

    Summary of Order
    
        1. The R&O (60 FR 37152, July 19, 1995) provided the private land 
    mobile radio (PLMR) community with a regulatory framework that promotes 
    efficient use of spectrum, increases technical flexibility, enhances 
    the deployment of new technologies, and promotes a competitive and 
    robust marketplace for product development. In this action, the 
    Commission clarifies its decisions in the R&O and where necessary, 
    makes appropriate modifications to the rules.
        2. In the R&O, the Commission adopted a channel plan based on 7.5 
    kHz channel spacing in the 150-174 MHz VHF band and 6.25 kHz channel 
    spacing in the 421-430 MHz, 450-470 MHz, and 470-512 MHz UHF bands. 
    Flexibility is provided to licensees by permitting them to aggregate up 
    to four narrowband channels to employ spectrum efficient wideband 
    technology. Additionally, licensees are provided with a simple 
    migration path because they will be able to remain on their currently 
    assigned center frequencies and can continue to use existing equipment 
    while they upgrade to new equipment.
        3. Several petitioners ask the Commission to reconsider the new 
    channel plan and instead adopt a channel plan based on 5 kHz channel 
    spacing claiming that the Commission's
    
    [[Page 2028]]
    
    decision to space channels at 7.5 kHz creates inefficient ``white 
    spaces'' in the VHF band. Additionally, they assert that the ability to 
    use wideband equivalent technologies by aggregating narrowband channels 
    is not taken into account in our rationale for rejecting 5 kHz spacing. 
    We disagree with these petitioners. In a 5 kHz channel plan, a user 
    would need to identify three contiguous channels to obtain a 12.5 kHz 
    channel, but only two are required in the adopted plan. Thus, the 
    adopted plan eases the transition for current users who desire to 
    implement a two-step transition to narrowband through 12.5 kHz 
    equipment. Petitioners also assert that inefficient white spaces are 
    created by our adopted channel plan, since 12.5 kHz VHF equipment would 
    actually use 15 kHz of spectrum by aggregating two 7.5 kHz VHF 
    channels. However, to use 12.5 kHz equipment in a plan based on 5 kHz 
    channels would also require licensees to use 15 kHz of spectrum because 
    they would have to aggregate three 5 kHz channels. In the UHF band, 
    12.5 kHz equipment also would use 15 kHz of spectrum in a 5 kHz channel 
    plan, but only 12.5 kHz of spectrum in the adopted plan. Furthermore, a 
    5 kHz channel plan would require users who choose to implement 6.25 kHz 
    equipment to acquire the same 15 kHz of spectrum needed for 12.5 kHz 
    equipment. Thus, a 5 kHz channel plan would create as much or more 
    white space than the adopted channel plan.
        4. Consequently, we conclude that our adopted 7.5/6.25 kHz channel 
    plan is more flexible than a 5 kHz plan because it will accommodate 
    users of 25, 12.5, 6.25, and 5 kHz equipment while accomplishing our 
    goal of increasing spectrum efficiency. Further, this channel plan 
    creates a flexible migration path, which is considered a critical 
    factor by current users. For these reasons, we decline to modify the 
    channel plan as adopted in the R&O. However, we are mindful of the fact 
    that some users may want to implement 5 kHz technology within their 
    existing 25 kHz bandwidth. Such a channelization, however, would 
    require the licensee to deviate from the adopted band plan. Therefore, 
    we will permit frequency coordinators to recommend frequencies 
    inconsistent with the adopted band plan, for any technology, including 
    5 kHz, provided that such a system will not cause harmful interference 
    to any existing system.
        5. In the R&O, we decided to manage the transition to narrowband 
    channels through the type acceptance process. This decision requires 
    that new equipment type accepted after August 1, 1996, and January 1, 
    2005, meet specified efficiency guidelines. We note, however, that this 
    approach does not impose a strict transition timetable upon individual 
    users.
        6. Petitioners argue that the conversion timetable for the type 
    acceptance of narrowband equipment is too short and fails to account 
    for normal product development cycles. They recommend that the first 
    transition date be extended to August 1, 1998, and that the second 
    transition date be extended to January 1, 2014. Other petitioners 
    oppose this request stating that such action is not necessary because 
    the R&O does not mandate the production or use of any particular type 
    of technology according to a fixed timetable.
        7. As noted, the transition dates established in the R&O do not 
    require manufacturers to take any specific action. Consequently, we 
    believe it is unnecessary to make extensive changes to the adopted 
    transition dates and, thus, deny the request to do so. Additionally, we 
    note that a number of manufacturers have already type accepted 
    equipment that is compliant with the new rules. However, in 
    consideration of the time elapsed between the R&O and adoption of this 
    MO&O, and because this MO&O modifies rules which affect the type 
    acceptance of equipment, we are extending the first transition date 
    from August 1, 1996, to February 14, 1997. Additionally, to remove the 
    uncertainty in trying to anticipate the amount of time necessary to 
    attain a type acceptance grant, we are amending 47 CFR 90.203 to 
    clarify that the transition dates refer to type acceptance application 
    filing deadlines, rather than type acceptance grants.
        8. The Association of Public-Safety Communications Officials-
    International, Inc. asks that we reconsider our decision not to adopt 
    specific transition deadlines for public safety users. We decline to 
    adopt such dates. The imposition of a mandate on any user, particularly 
    public safety entities, to replace existing equipment and systems, is 
    contrary to one of our basic goals in this proceeding of providing 
    maximum flexibility to individual users. Also, since public safety 
    entities are funded by local tax dollars, and are often constrained by 
    limited financial resources, subjecting these entities to such a 
    mandate could be unduly burdensome. Further, in light of the work of 
    the Public Safety Wireless Advisory Committee and the Commission's 
    overall evaluation and assessment of public safety wireless 
    communications in WT Docket No. 96-86 (61 FR 25185, May 20, 1996), it 
    would be premature at this time to make decisions regarding transition 
    dates for public safety users.
        9. In the R&O, we adopted spectrum efficiency standards that 
    require at least one voice channel per 12.5 kHz of channel bandwidth 
    for equipment type accepted after August 1, 1996, and at least one 
    voice channel per 6.25 kHz of channel bandwidth for equipment type 
    accepted after January 1, 2005. Additionally, after August 1, 1996, 
    equipment designed for data operation must be capable of supporting a 
    minimum data rate of 4800 bits per second per 6.25 kHz of bandwidth.
        10. Several petitioners request that the type acceptance rules be 
    amended to allow alternative showings of spectrum efficiency for low 
    power frequency reuse systems. We agree with the petitioners that there 
    is a place within the PLMR environment for spectrum efficient low-
    power, frequency reuse systems. However, we will not alter the 
    efficiency standard. instead, we will exempt all transmitters that 
    operate with less than 500 mW output power from the bit rate 
    requirement for type acceptance. Additionally, we will provide 
    manufacturers with additional flexibility to design spectrally 
    efficient transmitters. The Commission's Equipment Authorization 
    Division may, on a case by case basis, grant type acceptance to 
    equipment with slower bit rates than specified in 47 CFR 90.203(j)(3) 
    and 47 CFR 90.203(j)(5), provided that an acceptable technical analysis 
    is submitted with the application which demonstrates that the slower 
    data rate will provide more spectral efficiency than the standard data 
    rate.
        11. Some petitioners asked that we clarify the distinction between 
    digital voice and data. In this connection, we refer to the definitions 
    in 47 CFR part 2. Radios type accepted for telephony must meet the 
    voice channel standard, and those type accepted for telegraphy or 
    telemetry must meet the data rate standard. Further radios that are 
    type accepted for both telephony and telegraphy or telemetry must meet 
    both standards. Additionally, because 47 CFR 90.207(b) allows stations 
    authorized for telephony to use emissions for telecommand, the 
    telecommand function of such radios will not be subject to the data 
    rate standard. Also, because transmissions made via modem through the 
    external microphone port of an analog radio are limited to audio, the 
    data rate standard will not be applied to such uses. Finally, we 
    clarify that the spectrum efficiency requirements imposed by the R&O do 
    not apply to paging systems.
    
    [[Page 2029]]
    
        12. In the R&O, we adopted new power and antenna height limitations 
    based on ``safe harbor'' tables submitted by the Land Mobile 
    Communications Council (LMCC). These new limits allow various 
    combinations of effective radiated power (ERP) and antenna height above 
    average terrain (HAAT) based upon the size of an applicant's desired 
    service area and the applicant's operating frequency. In general, the 
    rules allow for a maximum ERP of 500 watts and maximum service area 
    radii of 40 km in the VHF band and 32 km in the UHF band. The rules 
    state that larger areas, up to 80 km, will be authorized provided that 
    the applicant demonstrates that the requested station parameters will 
    not produce coverage in excess of that which is required. However, 
    areas larger than 80 km will be authorized on a secondary basis. 
    Finally, these new rules only apply to new stations, which were defined 
    as stations not functionally integrated with an earlier-installed 
    system.
        13. Several petitioners argue that special separation criteria 
    should be developed for systems that operate in the 150-174 MHz and 
    421-512 MHz bands under conditions of extreme terrain, that a 
    streamlined process for deviating from the power/antenna height tables 
    be considered for applicants that operate in areas of non-uniform 
    terrain, that applicants be permitted to use any commonly accepted 
    propagation model to demonstrate radio system coverage, and that a 
    formal waiver not be required for such requests.
        14. We agree that special consideration should be given to the 
    power/antenna heights in areas of extreme terrain. We recognize that in 
    these areas, average terrain calculations may not provide accurate 
    depictions of the actual terrain over which a system will operate and 
    therefore our tables may not provide an appropriate antenna height/
    power combination for a desired service area size. We are modifying 47 
    CFR 90.205(d)(2) and 47 CFR 90.205(g)(2) to reflect that applicants may 
    deviate from the tables when operating in areas of non-uniform terrain. 
    Additionally, the rules allow the use of generally accepted engineering 
    practices and standards, including models that are widely accepted by 
    the engineering community, as producing outputs representative of real 
    world results. Applicants who demonstrate special circumstances (e.g. 
    extreme terrain conditions or need for a larger service area) will not 
    be required to submit a waiver request to the Commission. Rather, the 
    required engineering analysis should be submitted to the frequency 
    coordinator and as an attachment to the license application, FCC Form 
    600. Additionally, a waiver request will be unnecessary for applicants 
    who request service areas greater than 40 km in the VHF band and 32 km 
    in the UHF band. These applications, however, pursuant to footnote 4 in 
    Tables 1 and 2 of 47 CFR 90.205, must be accompanied by a justification 
    for the larger service area and include a technical analysis 
    demonstrating that the signal strength at the edge of the service area 
    is within the specified guidelines. Additionally, we will allow 
    applicants to exceed the reference antenna height limits if they 
    correspondingly lower their power.
        15. Petitioners seek clarification of the rules that would classify 
    all base stations with service areas greater than 80 km as secondary 
    arguing that certain geographic areas, particularly in western regions, 
    warrant special consideration because the terrain in those areas 
    provide few suitable transmitter sites.
        16. We note that licensees who need to communicate over large 
    distances generally employ systems that make extensive use of mobile 
    relay stations, which are afforded the protection of primary status 
    under our rules. Because mobile relay stations would typically be 
    within 80 km of another base station, primary status would be conferred 
    on the entire area that a licensee needs to cover. We believe that 
    coverage areas up to 80 km around a single base station will serve the 
    vast majority of licensees and are modifying 47 CFR 90.205(d)(3) and 47 
    CFR 90.205(g)(3) to confer primary status for communications within 80 
    km from a base station. We also recognize that some licensees' 
    operations may require primary status within a region larger than 80 
    km. Because we anticipate that a limited number of licensees will have 
    such needs, we will entertain waiver requests for those instances where 
    a licensee requests coverage by one base station for an area greater 
    that 80 km.
        17. Many petitioners seek clarification on what constitutes a new 
    station. As a general matter, we elected to exempt existing stations 
    from complying with the power/antenna height tables adopted in the R&O 
    in order to afford licensees flexibility to modify, expand, or upgrade 
    their facilities without adversely affecting their current operations. 
    47 CFR 90.135 provides examples of permissible modifications to 
    authorized stations. Stations that modify their existing authorization 
    in accordance with one of the listed modifications will not be subject 
    to the new power/antenna height rules. We decline to grant a request to 
    characterize the addition of base and mobile relay facilities that 
    operate on different frequencies from an existing system as an existing 
    system.
        18. Because 47 CFR 90.135(a) allows licensees to modify their 
    authorizations due to a change in emissions, the new power/antenna 
    height limits will not apply to systems that are modified by converting 
    to equipment designed for narrower channel bandwidths. Furthermore, if 
    the only modification that a licensee makes to a system is a narrowing 
    of its emission, a formal application for modification need not be 
    filed with the Commission. However, the licensee will be required to 
    notify the Commission of this change immediately, either by filing FCC 
    Form 405-A or submitting a letter in accordance with 47 CFR 90.135(d).
        19. Several organizations seek reconsideration of the power/antenna 
    height tables as they relate to private carrier paging channels. We 
    believe that our rules should reflect the differences between paging 
    systems and the majority of two-way mobile systems in the PLMR bands. 
    In this connection, we will allow new one-way paging operations to 
    operate at the same power levels that applied prior to the adoption of 
    the R&O, i.e., for most stations, 350 watts output power with no limit 
    on ERP, on the frequencies specifically reserved for one-way paging.
        20. Regarding the decision regarding the ability of manufacturers 
    to continue producing and supporting 25 kHz equipment through upgrades 
    and permissive changes, some petitioners argue that it is unnecessary 
    to prohibit manufacturers from making minor design changes to existing 
    25 kHz equipment because our rules already ensure a transition to more 
    narrowband equipment. This request is opposed by Securicor Radiocoms 
    Limited because it is inconsistent with the primary goal in this 
    proceeding since it would excuse compliance with the multi-mode 
    requirement. Our intent is to allow only those modifications which 
    would provide a multi-mode capability or a narrowband mode to existing 
    equipment. In these instances, manufacturers must obtain a new FCC 
    Identifier for their equipment. Modifications which entail the redesign 
    of existing equipment will not be allowed.
        21. When compared to wideband channels, i.e., 25 kHz channels, the 
    rules adopted in the R&O allow emissions on narrowband channels to 
    occupy a larger percentage of the channel. This combination of 
    increased channel occupancy and narrower channel spacing increases the
    
    [[Page 2030]]
    
    importance of frequency stability to reduce adjacent channel 
    interference. Therefore, the Commission adopted stringent frequency 
    stability requirements as recommended by the Telecommunications 
    Industry Association (TIA).
        22. SEA, Inc. contends that the frequency stability limits for 
    mobile radios designed to operate with channel bandwidths of 6.25 kHz 
    are too restrictive and recommends alternative limits. These 
    recommendations are supported by Motorola. We agree that, in the VHF 
    band, a less stringent requirement can be tolerated because of the 
    presence of a small guard band. Further, we believe that the frequency 
    coordination process can compensate for less stringent requirements in 
    the UHF band. Therefore, we are modifying 47 CFR 90.213 in accordance 
    with the suggestions of SEA.
        23. In order to accommodate our new channel plan, we adopted new 
    guidelines for authorized bandwidth. For equipment designed to operate 
    on 7.5 kHz or 6.25 kHz channels, the authorized bandwidth is 6 kHz and 
    for equipment designed to operate on 12.5 kHz channels the authorized 
    bandwidth is 11.25 kHz. SEA requests that the authorized bandwidth for 
    6.25 kHz channels in the UHF and VHF bands be reduced to 5 kHz in order 
    to allow same area operation on the narrowband channels.
        24. We decline to reduce the authorized bandwidth from 6 kHz to 5 
    kHz. The 6 kHz authorized bandwidth was chosen to provide manufacturers 
    with flexibility to implement a wide range of modulation techniques. We 
    note, however, that the emission mask only serves as an upper limit and 
    thus, manufacturers can employ any emission they desire as long as they 
    do not exceed the specified limits. Therefore, if a manufacturer 
    determines that same-area operations cannot be achieved on adjacent 
    narrowband channels, it can design its equipment with narrower 
    emissions.
        25. When determining the shape of a frequency mask, it is essential 
    that instrumentation requirements and measurement procedures are 
    defined. In general, transmitter emissions are measured using 
    established industry standards. In this connection, EIA/TIA Standard 
    603 instructs radio manufacturers to use a resolution bandwidth of 300 
    Hz or less. Consistent with this standard, in the R&O, we determined 
    that emissions of equipment designed to operate in the Refarming bands 
    should be measured using a resolution bandwidth of 100 Hz with the 
    measuring instrument in a peak hold mode.
        26. Motorola contends that using a resolution bandwidth of 100 Hz, 
    rather than the 300 Hz recommended by TIA, adds 5 dB of energy to the 
    adjacent channel and will result in reduced spectrum efficiency. SEA 
    agrees with Motorola, but recommends that the resolution bandwidth be 
    left at 100 Hz, and that the attenuation of the emission masks be 
    adjusted 5 dB.
        27. We decline to adjust the measurement technique adopted in the 
    R&O. The current industry trend for measuring digital emissions just 
    outside the channel, i.e., the adjacent channel, is to use measuring 
    instrumentation having a resolution capability of 1% of the bandwidth 
    of the carrier emission. This is evidenced by measurement procedures 
    and interpretations that have been developed in our rules for the 
    licensed Personal Communications Services (PCS) and unlicensed PCS 
    devices. A resolution bandwidth of 1% of the carrier emission bandwidth 
    provides a reasonable compromise where the emission's interference 
    potential can be measured and the instrumentation will not 
    detrimentally affect the measurement. Using a 100 Hz resolution 
    bandwidth for equipment in the Refarming bands approximates the 1% 
    standard that has been accepted by the affected industries in other 
    rule makings. Finally, we believe the claim of a 5 dB increase in 
    energy to the adjacent channel to be overstated because it assumes a 
    uniform level of energy across the measurement window without taking 
    into account the roll-off of energy at the band edges that results from 
    the emission mask. Therefore, we conclude that any effects on the 
    adjacent channel will be less than 5 dB.
        28. In order to promote flexibility for manufacturers to introduce 
    new and innovative modulation techniques in the PLMR bands below 512 
    MHz, we revised 47 CFR 90.211 to eliminate those requirements that were 
    primarily applicable to radios that use frequency modulation (FM). TIA 
    supports our objective, but disagrees with our decision to remove 
    specified deviation limits for FM and recommends that the modulation 
    limits be reinserted into the rules with their respective filter 
    characteristics. We disagree. Our rationale for removing the filter 
    specifications from 47 CFR 90.211 and the FM deviation limits from 47 
    CFR 90.209 was to provide manufacturers flexibility in designing and 
    implementing radio specifications. In this connection, we believe that 
    setting specifications for FM would be inconsistent with such 
    rationale.
        29. With the adoption of a new channel plan, many frequency 
    allocations and assignments were altered, particularly those of the 
    former low power offset channels. One result of the new channel plan is 
    that channels formally available as low power offset channels under 
    Section 47 CFR 90.267 are now available as regularly assignable 
    channels for high power operations. Additionally, the new channel plan 
    resulted in a reallocation of some of these channels from one radio 
    service to another by allocating channels that were between allocations 
    for two different radio services to the radio service or services where 
    the lower of the channels was allocated. Many Petitioners request that 
    we reexamine permissible uses for several former offset channels. Upon 
    reexamination, we are making several modifications to the frequency 
    tables in 47 CFR part 90.
        30. The R&O provided several operational alternatives for licensees 
    authorized on the former low power offset channels. One option is to 
    remain on their current channels and achieve primary status by 
    providing sufficient justification to raise power. A second option is 
    to migrate to designated low power channels and achieve primary status 
    on those channels. A third option is to remain on their current channel 
    at low power and continue to have secondary status.
        31. The Alarm Industry Communications Committee (AICC) contends 
    that licensees should be able to attain primary status without raising 
    power. Additionally, they ask whether stations wishing to increase 
    power need to file a letter notification or an application to provide 
    coordinates. Finally, AICC suggests that the Commission continue to 
    allow the current practice for alarm transmitters of providing 
    coordinates for the center of an operating area and the radius around 
    these coordinates in which transmitters will operate rather than 
    requiring each fixed transmitter to be individually licensed.
        32. As an initial matter, recognizing that any decision regarding 
    changes in power requirements on former low power offset channels will 
    be affected by our resolution of the exclusivity issues raised in the 
    Further Notice of Proposed Rule Making (60 FR 37148, July 18, 1995) in 
    this proceeding, we defer decisions on this matter to a future Order. 
    Regarding the requirement to furnish coordinates, we note that 
    situations exist where it is neither feasible nor desirable for a 
    licensee to furnish coordinates of all transmitters in their system. 
    Therefore, we will allow licensees to supply only coordinates of
    
    [[Page 2031]]
    
    the center of an operating area and a radius when all stations are 
    fixed, low power, i.e., not to exceed 2 watts, stations.
        33. When we eliminated the low power offset channels in the R&O, we 
    established new low power offset channels 3.125 kHz removed from 
    regularly assignable channels and authorized them on a secondary, non-
    interference basis. The creation of these channels was opposed by the 
    Personal Communications Industry Association which contends that low 
    power users will be accommodated through coordinator designated 
    exclusive low power channels and the color dot channels and that these 
    new low power offset channels will recreate difficulties which existed 
    with the former low power offset channels Finally, they state that 
    these new low power offset channels may have the unintended effect of 
    preventing the use of primary channels by wideband, spectrally 
    efficient systems. We agree that these low power offset channels could 
    potentially have a detrimental effect on the operations on primary 
    channels and will therefore remove the new low power offset channels 
    from 47 CFR 90.267(b). However, in light of technological advances and 
    usage patterns in these bands, we reserve the right to revisit this 
    issue in the future.
        34. When we established the Emergency Medical Radio Service (EMRS), 
    we assigned the 453 MHz and 458 MHz frequencies used for medical paging 
    systems in the Special Emergency Radio Service (SERS) to the EMRS. SERS 
    users were permitted to continue operating on these channels as primary 
    users for a period of five years. In the R&O, the SERS frequencies 
    reassigned to the EMRS were rechannelized at the new narrowband 
    spacings. Several petitioners request removal of the new channels that 
    arose from splitting the 453 MHz and 458 MHz channels from the SERS. We 
    agree and will remove the 453 MHz narrowband channels from the SERS 
    frequency table in 47 CFR 90.53(a).
        35. In the EMRS, MED channels are used for emergency medical 
    communications. Prior to adoption of the R&O, there were 10 MED 
    channels, designated as MED-1 through MED-10. The new channel plan 
    created 3 new MED channels higher in frequency than each existing MED 
    channel. These new channels, designated as MED-A through MED-X, were 
    assigned as follows: MED-A, MED-B, and MED-C were assigned between MED-
    1 and MED-2, MED-D, MED-E, and MED-F were assigned between MED-2 and 
    MED-3. The new MED channels higher in frequency than MED-9 and MED-10 
    were not labeled. Several Petitioners propose changing the MED channel 
    labeling scheme to one that is entirely numeric.
        36. We agree that a different labeling approach is needed for the 
    new MED channels because any confusion regarding their designation 
    could potentially interfere with the communication of messages 
    necessary to ensure public safety. Therefore, we will use a trailing 1, 
    2, or 3 to designate the position of the new MED channels in relation 
    to the existing MED channels. For example, the channel 6.25 kHz above 
    MED-3 will be designated as MED-31, the channel 12.5 kHz above MED-3 as 
    MED-32, and the channel 18.25 kHz above MED-3 as MED-33. We will adopt 
    this labeling approach for designating the channel positions accorded 
    to each of the 10 MED channels.
        37. Currently, 47 CFR 90.217 exempts transmitters used in the 
    Business Radio Service that have an output power not exceeding 120 
    milliwatts from the technical requirements imposed by our rules, 
    provided that they meet minimum emission limitations. Many petitioners 
    request that this exemption be expanded to include all PLMR services. 
    We agree and are expanding the current exemption to include all private 
    land mobile radio services.
        38. In order to assure that transient frequencies do not cause 
    excessive interference to land mobile licensees and television 
    receivers in adjacent bands, the Commission adopted standards for 
    transient frequency behavior. These standards are based on EIA/TIA 
    standard 603, which sets allowable transient response for radios that 
    operate in three frequency bands: 30-300 MHz, 300-500 MHz, and 500-1000 
    MHz.
        39. Several petitioners request that we clarify the new rules by 
    declaring that they are only applicable to equipment type accepted 
    after a specific date. Motorola recommends that the three frequency 
    band columns listed in 47 CFR 90.214 be replaced by two frequency band 
    columns, one for 150-174 MHz and one for 421-512 MHz. We decline to 
    modify the implementation date of Sec. 90.214 of our rules. Since the 
    new rules took effect on August 18, 1995, the Commission's Equipment 
    Authorization Division has been granting type acceptance based on 
    transmitters meeting all of the new technical requirements. Therefore, 
    because there have been no objections to the transient frequency 
    requirements of 47 CFR 90.214, we see no reason to grant type 
    acceptance to transmitters that do not meet the new requirements. 
    Additionally, granting type acceptance to radios that do not meet the 
    new requirements would be administratively burdensome because it would 
    create two categories of transmitters which would be difficult to track 
    and identify in the future. We are, however adopting Motorola's 
    recommendation to apply the standards for radios that operate in the 
    421-500 MHz band to radios that operate in the 500-512 MHz band.
        40. In the R&O, we eliminated 47 CFR 90.271 which provided for 5 
    kHz narrowband channels that were offset either 2.5 kHz or 7.5 kHz from 
    regularly assignable channels in the 150-170 MHz band. Additionally, 
    the R&O permits licensees on these channels to remain on their 
    currently authorized frequency until August 1, 2001 if interference is 
    not experienced. Securicor asserts that users of these 5 kHz channels, 
    who operate the most spectrally-efficient equipment in the PLMR bands, 
    are being treated unfairly because they must modify their systems to 
    comply with the new channel plan even if they do not experience or 
    cause interference.
        41. We share Securicor's concern about unnecessarily causing 
    disruption to existing operations. Therefore, to accommodate the needs 
    of our licensees and to prevent the premature obsolescence of 
    narrowband systems that are already operating in the 150-174 MHz band, 
    we will extend by two years, until August 1, 2003, the date by which 
    these licensees must migrate to one of the new VHF channels. 
    Additionally, licensees may remain on their currently assigned channels 
    after August 1, 2003, on a secondary, non-interference basis.
        42. We recently adopted rules in PR Docket No. 92-257 (60 FR 35507, 
    July 10, 1995) to allow industrial and land transportation entities to 
    use nine VHF maritime public correspondence channel pairs for standard 
    two-way base/mobile operations. 47 CFR 90.283 imposes power/antenna 
    height restrictions on these frequencies and requires minimum 
    separation distances from protected entities.
        43. LMCC requests that the 25 kHz wide channels listed in 47 CFR 
    90.283 of our rules be integrated into the new 6.25 kHz narrowband 
    channel plan. We note that new 25 kHz Part 90 radios will no longer be 
    type accepted in the 150-174 MHz band after the effective date of the 
    rule amendments of this MO&O; thus, we find it unreasonable to require 
    their use. Additionally, we believe that the current restrictions are 
    sufficient to ensure that PLMR licensees operating on narrowband 
    channels will not cause harmful interference to the protected
    
    [[Page 2032]]
    
    entities. Therefore, we modify 47 CFR 90.283 to provide narrowband 
    channel spacings for PLMR users on the shared maritime public 
    correspondence frequencies.
        44. The Industrial Telecommunications Association requests that we 
    adopt changes in the power/antenna height tables of 47 CFR 90.283(c) 
    and 47 CFR 90.283(d) to accommodate users that need to exceed the 
    imposed limits due to circumstances such as terrain effects or coverage 
    requirements. We are not modifying the rules, rather, we will require a 
    request for waiver of the power/antenna height limits of 47 CFR 90.283.
        45. With the adoption of this Memorandum Opinion and Order, we 
    finalize the new channel plan and incorporate certain modifications to 
    our regulatory and technical framework for the PLMR services in 47 CFR 
    part 90. These new rules will provide greater technical flexibility for 
    PLMR licensees and equipment manufacturers, promote the highly 
    effective and efficient use of the PLMR spectrum, and create an 
    environment which will provide users the opportunity to introduce 
    advanced technologies into the private land mobile radio services.
        46. The rules are set forth at the end of this document.
        47. The rules contained herein have been analyzed with respect to 
    the Paperwork Reduction Act of 1980, 44 U.S.C. 3501 et seq., and found 
    to contain no new or modified form, information collection, and/or 
    recordkeeping, labeling, disclosure, or record retention requirements 
    and will not increase or decrease burden hours imposed on the public.
        48. This Memorandum Opinion and Order and the rule amendments are 
    issued under the authority of 47 U.S.C. 154(i), 303(r), and 405.
    
    Final Regulatory Flexibility Analysis
    
        49. As required by Section 603 of the Regulatory Flexibility Act, 5 
    U.S.C. 603 (RFA), an Initial Regulatory Flexibility Analysis (IRFA) was 
    incorporated in the Notice of Proposed Rule Making (56 FR 31097, July 
    9, 1991) in PR Docket 92-235. The Commission sought written public 
    comments on the proposals in the Refarming Notice, including on the 
    IRFA. The Commission's Final Regulatory Flexibility Analysis (FRFA) in 
    this Memorandum Opinion and Order conforms to the RFA, as amended by 
    the Contract With America Advancement Act of 1996.\1\
    ---------------------------------------------------------------------------
    
        \1\ Pub. L. 104-121, 110 Stat. 847 (1996) (CWAAA). Subtitle II 
    of the CWAAA is ``The Small Business Regulatory Enforcement Fairness 
    Act of 1996'' (SBREFA), codified at 5 U.S.C. 601 et seq.
    ---------------------------------------------------------------------------
    
    A. Need For and Objective of the Proposed Rule
    
        50. Our objective is to increase spectrum efficiency and facilitate 
    the introduction of advanced technologies into the 150-174 MHz, 421-430 
    MHz, 450-470 MHz, and 470-512 MHz PLMR bands. The Report and Order in 
    this proceeding modified the Commission's rules to resolve many of the 
    technical issues which inhibited the use of spectrally efficient 
    technologies in these frequency bands. This MO&O address petitions for 
    reconsideration and clarification received in response to the Report 
    and Order.
        51. We find that the potential benefits to the PLMR community 
    exceed any negative effects that may result from the promulgation of 
    rules for this purpose. Thus, we conclude that the public interest is 
    served by modifying our rules to increase the spectral efficiency of 
    the PLMR bands.
    
    B. Summary of Significant Issues Raised by the Public Comments in 
    Response to the Initial Regulatory Flexibility Analysis
    
        52. No comments were submitted in direct response to the IRFA. We 
    have, however, reviewed general comments that may impact small 
    businesses.
    
    C. Description and Estimate of the Number of Small Entities Subject to 
    Which the Rules Apply
    
        53. The rules adopted in this Memorandum Opinion and Order will 
    apply to small business that choose to use, manufacture, or design 
    radios that operate in the PLMR bands below 512 MHz. The are no 
    Commission imposed requirements, however, for any entity to use or 
    produce these products.
    
    Estimates for PLMR Manufacturers
    
        54. The Commission has not developed a definition of small entities 
    specifically applicable to PLMR manufacturers. Therefore, for the 
    purposes of this analysis, the applicable definition of small entity is 
    the definition under the Small Business Administration (SBA) rules 
    applicable to radio and television broadcasting and communications 
    equipment manufacturers. The SBA defines a small entity in this 
    category as one in which less than 750 persons are employed.\2\
    ---------------------------------------------------------------------------
    
        \2\ See 13 CFR 121.201, Standard Industrial Classification (SIC) 
    Code 3663.
    ---------------------------------------------------------------------------
    
        55. Because the Regulatory Flexibility Act amendments were not in 
    effect until the record in this proceeding was closed, the Commission 
    was unable to request information regarding the number of small 
    entities that manufacture PLMR equipment and is unable at this time to 
    determine the number of manufacturers which are small businesses. 
    However, the 1992 Census of Manufacturers, conducted by the Bureau of 
    Census, which is the most comprehensive and recent information 
    available, shows that approximately 925 out of the 948 entities 
    manufacturing radio and television transmitting equipment in 1992 
    employed less than 750 persons.\3\ We are unable to discern from the 
    Census data precisely how many of these manufacturers produce private 
    land mobile radios. Further, any entity may choose to manufacture such 
    radio equipment. Therefore, for purposes of our evaluations and 
    conclusions in this Final Regulatory Flexibility Analysis, we estimate 
    that there are at least 925 manufacturers and potential manufacturers 
    of PLMR equipment which are small businesses, as that term is defined 
    by the SBA.
    ---------------------------------------------------------------------------
    
        \3\ See 1992 Census of Manufacturers, Industry Series, 
    Communication Equipment, Including Radio and Television, Industries 
    3651, 3652, 3661, 3663, and 3669, Issued March 1995, Table 4. This 
    table shows a total of 23 manufacturers with an average of 1,000 
    employees or more and 908 with an average of 499 employees or less. 
    It lists a total of 17 manufacturers with an average of 500-999 
    employees. Because we could not determine the number of 
    manufacturers in 500-999 category with an average of 750 employees 
    or less, we assume all 17 are small businesses for the purpose of 
    this evaluation.
    ---------------------------------------------------------------------------
    
    Estimates for PLMR Licensees
    
        56. Private land mobile radio system serve an essential role in a 
    vast range of industrial, business, land transportation, and public 
    safety activities. These radios are used by companies of all sizes 
    operating in all U.S. business categories. Because of the vast array of 
    PLMR users, the Commission has not developed nor would it be possible 
    to develop a definition of small entities specifically applicable to 
    PLMR users. For the purpose of determining whether a licensee is a 
    small business as defined by the SBA, each licensee would need to be 
    evaluated within its own business area.
        57. Because the Regulatory Flexibility Act amendments were not in 
    effect until the record in this proceeding was closed, the Commission 
    was unable to request information regarding the number of small 
    entities that are private land mobile radio licensees. Therefore, the 
    Commission is unable at this time to determine the number of small 
    businesses which could be impacted by the rules. However, the 
    Commission's fiscal year 1994 annual report indicates that at the end 
    of fiscal year 1994 there were 1,101,711 licensees operating 12,882,623 
    transmitters in the PLMR
    
    [[Page 2033]]
    
    bands below 512 MHz.\4\ Further, because any entity engaged in a 
    commercial activity is eligible to hold a PLMR license, these rules 
    could potentially impact every small business in the U.S.
    ---------------------------------------------------------------------------
    
        \4\ See Federal Communications Commission, 60th Annual Report, 
    Fiscal Year 1994 at 120-121.
    ---------------------------------------------------------------------------
    
    D. Description of Projected Reporting, Recordkeeping, and Other 
    Compliance Requirements of the Rules
    
        58. There are no general reporting or recordkeeping requirements. 
    However, for certain requests we have substituted a new, less 
    burdensome reporting requirement in place of a requirement for 
    applicants to file applications for waiver or modification.
        (1) In order to obtain a type acceptance grant, PLMR radios that 
    transmit data must meet a specified spectrum efficiency standard--
    measured in bits per second per Hertz. For radios that transmit bit 
    rates slower than the specified standard, our rules permit 
    manufacturers an alternative to requesting a waiver of the technical 
    rules. Type acceptance grants may be obtained, provided that the 
    applicant submits a technical analysis which demonstrates that the 
    slower data rate will provide more spectral efficiency than the 
    standard data rate.
        (2) Our rules provide allowable combinations of antenna height and 
    effective radiated power (ERP) based on the size of the area an 
    applicant intends to serve and a certain signal strength at the edge of 
    this service area. Rather than filing a waiver request, we are allowing 
    applicants to exceed the reference antenna height, provided they 
    correspondingly lower their ERP and demonstrate that the signal 
    strength of their system at the edges of their service area meets the 
    general limits.
        (3) Licensees, when making changes to their radio systems, are 
    normally required to file an application for modification. However, in 
    instances where the only modification to a radio system is a narrowing 
    of its operating bandwidth, we will not require an application for 
    modification. Instead, we are only requiring that licensees notify the 
    Commission of the change.
    
    E. Steps Taken by Agency To Minimize Significant Economic Impact on 
    Small Entities Consistent With Stated Objectives
    
        59. The Commission, in this MO&O, has considered petitions to 
    reconsider the rules adopted in the Report and Order in this 
    proceeding. In doing so, the Commission has adopted several 
    alternatives which minimize burdens placed on small entities. First, 
    the Commission reaffirms its decision to implement the transition to 
    narrowband equipment through the type acceptance process. Users are not 
    required to replace their existing systems, rather they are provided 
    flexibility to choose a transition schedule that best fulfills their 
    needs while balancing technical capabilities and financial 
    considerations. Second, private paging systems, many of which are 
    operated by small entities, will not be subject to many of the new 
    rules. This approach, by not imposing new requirements on private 
    paging licensees, will lower the cost of expanding such systems. Third, 
    we provide applicants the ability to deviate from the new power/antenna 
    height restrictions, which only apply to new stations, without applying 
    for a waiver. This approach eliminates the need for small entities to 
    remit waiver fees of $125 per rule section per station. Additionally, 
    it eliminates the need for small entities to expend clerical support to 
    prepare these waiver requests. Fourth, we allow manufacturers to make 
    permissive changes to previously type accepted equipment. This will 
    allow small entities to continue supporting their existing equipment 
    and customer base in advance of changing their production facilities to 
    manufacture radios compliant with the new spectrum efficiency rules. 
    Fifth, we ease the frequency stability requirements for narrowband 
    radios and extend the exemption from technical standards for low power 
    transmitters to all radio services. These changes will lower 
    development and production costs for small entities. Sixth, we will not 
    require licensees operating on 5 kHz channels under former Sec. 90.271 
    of our rules to comply with the new channel plan by August 1, 2001. 
    Instead, these licensees can continue operating on their current 
    frequency as long as they do not cause interference to other users. 
    This approach will lower costs to small entities by not requiring those 
    who operate such systems to modify them sooner than necessary or at 
    all.
    
    F. Commission's Outreach Efforts To Learn of and Respond to the Views 
    of Small Entities Pursuant to 5 U.S.C. 609
    
        60. The Commission has, in this proceeding, taken several steps to 
    learn and respond to the views of small entities. In response to the 
    Refarming Notice, we held two public forums. On November 14, 1991, the 
    Private Radio Bureau, in cooperation with the Annenberg Washington 
    Program, Communications Policy Studies of Northwestern University, 
    sponsored a conference on Refarming and on May 16, 1993, the Private 
    Radio Bureau held a Refarming technology Roundtable. Additionally, 
    throughout the course of this proceeding the representatives of the 
    Private Wireless Division (PWD) of the Wireless Telecommunications 
    Bureau have had numerous ex parte discussions with small entities or 
    their representatives. For example, the PWD has met with many of the 
    frequency coordinators for the nineteen PLMR services.5
    ---------------------------------------------------------------------------
    
        \5\ Many of the frequency coordinators are trade associations 
    and represent their members, many of which are small entities, views 
    on telecommunications matters.
    ---------------------------------------------------------------------------
    
    G. Report to Congress
    
        61. The Commission shall send a copy of this final Regulatory 
    Flexibility analysis, along with the Memorandum Opinion and Order, in a 
    report to Congress pursuant to the SBREFA.6 A copy of this FRFA 
    will also be published in the Federal Register.

    \1\ ton is the instant when a 1 kHz test signal is completely suppressed, including any capture time due to     
      phasing.                                                                                                      
    t1 is the time period immediately following ton.                                                                
    t2 is the time period immediately following t1.                                                                 
    t3 is the time period from the instant when the transmitter is turned off until toff.                           
    toff is the instant when the 1 kHz test signal starts to rise.                                                  
    2 During the time from the end of t2 to the beginning of t3, the frequency difference must not exceed the limits
      specified in Sec.  90.213.                                                                                    
    3 Difference between the actual transmitter frequency and the assigned transmitter frequency.                   
    4 If the transmitter carrier output power rating is 6 watts or less, the frequency difference during this time  
      period may exceed the maximum frequency difference for this time period.
