Sec. 27.55  Signal strength limits.



    (a) Field strength limits. For the following bands, the predicted or 

measured median field strength at any location on the geographical 

border of a licensee's service area shall not exceed the value specified 

unless the adjacent affected service area licensee(s) agree(s) to a 

different field strength. This value applies to both the initially 

offered service areas and to partitioned service areas.

    (1) 2110-2155, 2305-2320 and 2345-2360 MHz bands: 47 dB[mu] V/m.

    (2) 698-764 and 776-794 MHz bands: 40 dB[mu] V/m.

    (3) The paired 1392-1395 MHz and 1432-1435 MHz bands and the 

unpaired 1390-1392 MHz band (1.4 GHz band): 47 dB[mu]V/m.

    (b) Power flux density limit. For base and fixed stations operating 

in the 698-746 MHz band, with an effective radiated power (ERP) greater 

than 1 kW, the power flux density that would be produced by such 

stations through a combination of antenna height and vertical gain 

pattern must not exceed 3000 microwatts per square meter on the ground 

over the area extending to 1 km from the base of the antenna mounting 

structure.
