Sec. 90.635 Limitations on power and antenna height.
(a) Systems to be located within 24 km. (15 mi.) of the geographic
center of the 50 urbanized areas detailed in table 1 will be considered
``urban'' systems. All others will be considered ``suburban'' systems.
(b) The effective radiated power and antenna height, for base
stations used in suburban-conventional systems of communications, shall
be no greater than 500 watts (27 dBw) and 152 m. (500 ft.) above average
terrain (AAT), respectively, or the equivalent as determined from table
2. These are maximum values, and applicants are required to justify
power levels and antenna heights requested. For service area
requirements less than 32 km. (20 mi.) in radius, see table 3.
(c) The effective radiated power and antenna height for base
stations used in trunked and urban-conventional systems may not exceed 1
kilowatt (30 dBw) and 304 m. (1,000 ft.) above average terrain (AAT),
respectively, or the equivalent thereof as determined from table 2.
These are maximum values, and applicants will be required to justify
power levels and antenna heights requested. For service area
requirements less than 32 km (20 mi.) in radius, see table 4.
(d) The maximum output power of the transmitter for mobile stations
is 100 watts (20 dBw).
