The Federal Communications Commission is mandating all Public Safety and Industrial/Business licensees convert existing 25 kHz (a.k.a. wide band) efficiency operations in the VHF and UHF bands to minimum 12.5 kHz (a.k.a. narrow band) efficiency analog or digital operation. To implement this mandate, the FCC developed rules and deadlines that impact both radio users and equipment providers.



January 1, 2011: Applications for new licenses must specify at least 12.5 kHz efficiency. The FCC will no longer accept applications for systems operating at 25 kHz efficiency. Applications for modifications of existing licenses to expand the authorized interference contour (19 dBu VHF, 21 dBu UHF) must specify at least 12.5 kHz efficiency. The FCC will no longer accept modifications for expansion of service areas to systems operating at 25 kHz efficiency. Changes that can trigger such expansion include increasing the antenna height, transmitter power, or adding or moving a transmitter site.

January 1, 2013: All licensees must convert to and operate in at least 12.5 kHz efficiency. Those who have not converted to narrow band mode may be open to enforcement action by the FCC, which could include warnings, fines, or even loss of licenses.The FCC has stated that this deadline will not be extended.
