   (a) The following power limits and related requirements apply to stations
   transmitting in the 2305-2320 MHz band or the 2345-2360 MHz band.

   (1) Base and fixed stations. (i) For base and fixed stations transmitting in
   the 2305-2315 MHz band or the 2350-2360 MHz band:

   (A) The average equivalent isotropically radiated power (EIRP) must not
   exceed 2,000 watts within any 5 megahertz of authorized bandwidth and must
   not exceed 400 watts within any 1 megahertz of authorized bandwidth.

   (B) The peak-to-average power ratio (PAPR) of the transmitter output power
   must not exceed 13 dB. The PAPR measurements should be made using either an
   instrument  with complementary cumulative distribution function (CCDF)
   capabilities to determine that PAPR will not exceed 13 dB for more than 0.1
   percent of the time or other Commission approved procedure. The measurement
   must be performed using a signal corresponding to the highest PAPR expected
   during periods of continuous transmission.

   (ii) For base and fixed stations transmitting in the 2315-2320 MHz band or
   the 2345-2350 MHz band, the peak EIRP must not exceed 2,000 watts.

   equipment (CPE) stations transmitting in the 2305-2320 MHz band or in the
   2345-2360 MHz band, the peak EIRP must not exceed 20 watts within any 5
   megahertz of authorized bandwidth. Fixed CPE stations transmitting in the
   2305-2320  MHz band or in the 2345-2360 MHz band must employ automatic
   transmit power control when operating so the stations operate with the
   minimum power necessary for successful communications. The use of outdoor
   antennas for CPE stations or outdoor CPE station installations operating
   with  2  watts  per 5 megahertz or less average EIRP using the stepped
   emissions  mask  prescribed  in  § 27.53(a)(3)  is prohibited except if
   professionally installed in locations removed by 20 meters from roadways or
   in locations where it can be shown that the ground power level of -44 dBm in
   the A or B blocks or -55 dBm in the C or D blocks will not be exceeded at
   the  nearest  road location. The use of outdoor antennas for fixed CPE
   stations operating with 2 watts per 5 megahertz or less average EIRP and the
   emissions mask prescribed in § 27.53(a)(1)(i) through (iii) is permitted in
   all locations. For fixed WCS CPE using TDD technology, the duty cycle must
   not exceed 38 percent;

   (3) Mobile and portable stations. (i) For mobile and portable stations
   transmitting  in the 2305-2315 MHz band or the 2350-2360 MHz band, the
   average  EIRP  must not exceed 50 milliwatts within any 1 megahertz of
   authorized bandwidth, except that for mobile and portable stations compliant
   with 3GPP LTE standards or another advanced mobile broadband protocol that
   avoids concentrating energy at the edge of the operating band the average
   EIRP must not exceed 250 milliwatts within any 5 megahertz of authorized
   bandwidth but may exceed 50 milliwatts within any 1 megahertz of authorized
   bandwidth. For mobile and portable stations using time division duplexing
   (TDD) technology, the duty cycle must not exceed 38 percent in the 2305-2315
   MHz  and  2350-2360  MHz bands. Mobile and portable stations using FDD
   technology are restricted to transmitting in the 2305-2315 MHz band. Power
   averaging shall not include intervals in which the transmitter is off.

   (ii) Mobile and portable stations are not permitted to transmit in the
   2315-2320 MHz and 2345-2350 MHz bands.

   (iii)  Automatic  transmit power control. Mobile and portable stations
   transmitting in the 2305-2315 MHz band or in the 2350-2360 MHz band must
   employ automatic transmit power control when operating so the stations
   operate with the minimum power necessary for successful communications.

   (iv) Prohibition on external vehicle-mounted antennas. The use of external
   vehicle-mounted antennas for mobile and portable stations transmitting in
   the 2305-2315 MHz band or the 2350-2360 MHz band is prohibited.

   network after the 716-722 or 722-728 MHz bands licensee deploys a network on
   its 716-722 or 722-728 MHz spectrum in the same geographic market, the
   716-722 or 722-728 MHz bands licensee will work with the licensee with
   uplink  operations in the 698-716 MHz band to identify sites that will
   require additional filtering, and will help the licensee operating in the
   698-716 and 728-746 MHz bands to identify proper filters;

   (ii)  The  716-722 or 722-728 MHz bands licensee must permit licensees

   licensee in the 716-722 or 722-728 MHz bands deploys a network in the same
   geographic market, the 716-722 or 722-728 MHz bands licensee will work with
   licensees in the 698-716 and 728-746 MHz bands to identify sites that will
   need additional filtering and will purchase and pay for installation of
   required filters on such sites.

   (g) [Reserved]

   (h) The following power limits shall apply in the BRS and EB§ 

   (1) Main, booster and base stations. (i) The maximum EIRP of a main, booster
   or base station shall not exceed 33 dBW + 10log(X/Y) dBW, where X is the
   actual channel width in MHz and Y is either 6 MHz if prior to transition or
   the station is in the MBS following transition or 5.5 MHz if the station is
   in the LBS and UBS following transition, except as provided in paragraph
   (h)(1)(ii) of this section.

   (ii) If a main or booster station sectorizes or otherwise uses one or more
   transmitting antennas with a non-omnidirectional horizontal plane radiation
   pattern, the maximum EIRP in dBW in a given direction shall be determined by
   the  following  formula:  EIRP  =  33  dBW  +  10  log(X/Y)  dBW  + 10
   log(360/beamwidth) dBW, where X is the actual channel width in MHz, Y is
   either  (i)  6 MHz if prior to transition or the station is in the MBS
   following transition or (ii) 5.5 MHz if the station is in the LBS and UBS

   (3) For television transmission, the peak power of the accompanying aural

   diminish the potential for harmful interference.

   (4) For main, booster and response stations utilizing digital emissions with
   non-uniform  power  spectral density (e.g. unfiltered QPSK), the power
   measured within any 100 kHz resolution bandwidth within the 6 MHz channel
   occupied by the non-uniform emission cannot exceed the power permitted
   within any 100 kHz resolution bandwidth within the 6 MHz channel if it were
   occupied by an emission with uniform power spectral density, i.e., if the
   maximum permissible power of a station utilizing a perfectly uniform power
   spectral density across a 6 MHz channel were 2000 watts EIRP, this would
   result  in a maximum permissible power flux density for the station of
   2000/60 = 33.3 watts EIRP per 100 kHz bandwidth. If a non-uniform emission
   were substituted at the station, station power would still be limited to a
   maximum of 33.3 watts EIRP within any 100 kHz segment of the 6 MHz channel,
   irrespective of the fact that this would result in a total 6 MHz channel
   power of less than 2000 watts EIRP.

   (i) Peak transmit power shall be measured over any interval of continuous
   transmission using instrumentation calibrated in terms of 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, etc., so as to
   obtain a true peak measurement for the emission in question over the full
   bandwidth of the channel.
