  §  24.132   Power and antenna height limits.

   (a) Stations transmitting in the 901–902 MHz band are limited to 7
   watts e.r.p.

   (b) Mobile stations transmitting in the 930–931 MHz and 940–941 MHz
   bands are limited to 7 watts e.r.p.

   (c) Base stations transmitting in the 930–931 MHz and 940–941 MHz bands
   are limited to 3500 watts e.r.p. per authorized channel and are
   unlimited in antenna height except as provided in paragraph (d) of this
   section.

   (d)(1) MTA and regional base stations located between 200 kilometers
   (124 miles) and 80 kilometers (50 miles) from their licensed service
   area border are limited to the power levels in the following table:
   Antenna HAAT in meters (feet) (see § 24.53 for HAAT HAAT calculation
   method) Effective radiated power (e.r.p.) (watts)
   183 (600) and below 3500
   183 (600) to 208 (682) 3500 to 2584
   208 (682) to 236 (775) 2584 to 1883
   236 (775) to 268 (880) 1883 to 1372
   268 (880) to 305 (1000) 1372 to 1000
   305 (1000) to 346 (1137) 1000 to 729
   346 (1137) to 394 (1292) 729 to 531
   394 (1292) to 447 (1468) 531 to 387
   447 (1468) to 508 (1668) 387 to 282
   508 (1668) to 578 (1895) 282 to 206
   578 (1895) to 656 (2154) 206 to 150
   656 (2154) to 746 (2447) 150 to 109
   746 (2447) to 848 (2781) 109 to 80
   848 (2781) to 963 (3160) 80 to 58
   963 (3160) to 1094 (3590) 58 to 42
   1094 (3590) to 1244 (4080) 42 to 31
   1244 (4080) to 1413 (4636) 31 to 22
   Above 1413 (4636) 16

   (2) For heights between the values listed in the table, linear
   interpolation shall be used to determine maximum e.r.p.

   (e) MTA and regional base stations located less than 80 kilometers (50
   miles) from the licensed service area border must limit their effective
   radiated power in accordance with the following formula:

   PW=0.0175xdkm* * 6.6666xhm* * −3.1997

   PW is effective radiated power in watts

   dkm is distance in kilometers

   hm is antenna HAAT in meters; see § 24.53 for HAAT calculation method

   (f) All power levels specified in this section are expressed in terms
   of the maximum power, averaged over a 100 millisecond interval, when
   measured with instrumentation calibrated in terms of an rms-equivalent
   voltage with a resolution bandwidth equal to or greater than the
   authorized bandwidth.

   (g) Additionally, PCS stations will be subject to any power limits
   imposed by international agreements.

   [ 58 FR 59183 , Nov. 8, 1993;  59 FR 15269 , Mar. 31, 1994, as amended at
    62 FR 27511 , May 20, 1997;  65 FR 35853 , June 6, 2000]
