Sec. 90.219  Use of signal boosters.

    Licensees authorized to operate radio systems in the frequency bands 
above 150 MHz may employ signal boosters at fixed locations in 
accordance with the following criteria:
    (a) The amplified signal is retransmitted only on the exact 
frequency(ies) of the originating base, fixed, mobile, or portable 
station(s). The booster will fill in only weak signal areas and cannot 
extend the system's normal signal coverage area.
    (b) Class A narrowband signal boosters must be equipped with 
automatic gain control circuitry which will limit the total effective 
radiated power (ERP) of the unit to a maximum of 5 watts under all 
conditions. Class B broadband signal boosters are limited to 5 watts ERP 
for each authorized frequency that the booster is designed to amplify.
    (c) Class A narrowband boosters must meet the out-of-band emission 
limits of Sec. 90.209 for each narrowband channel that the booster is 
designed to amplify. Class B broadband signal boosters must meet the 
emission limits of Sec. 90.209 for frequencies outside of the booster's 
design passband.
    (d) Class B broadband signal boosters are permitted to be used only 
in confined or indoor areas such as buildings, tunnels, underground 
areas, etc., or in remote areas, i.e., areas where there is little or no 
risk of interference to other users.

    (e) The licensee is given authority to operate signal boosters 
without separate authorization from the Commission. Type-accepted 
equipment must be employed and the licensee must ensure that all 
applicable rule requirements are met.
    (f) Licensees employing either Class A narrowband or Class B 
broadband signal boosters as defined in Sec. 90.7 are responsible for 
correcting any harmful interference that the equipment may cause to 
other systems. Normal co-channel transmissions will not be considered as 
harmful interference. Licensees will be required to resolve interference 
problems pursuant to Sec. 90.173(b).
