§ 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.
