FCC Grants Narrowbanding Extensions to NYC, Chicago and Philly (12/27/12)
The FCC granted the VHF and UHF narrowbanding waiver requests of three of the nation’s largest cities, just days before the Jan. 1, 2013, deadline.

New York City received separate extension dates for two different components of its radio communications system. The main portion of the UHF system used by the Fire Department of New York (FDNY) and the New York Police Department (NYPD) operates on frequencies in the UHF T-band, for which the Jan. 1, 2013, narrowbanding deadline was waived earlier this year. The city also received a waiver for additional non-T-band channels that are operationally integrated with the T-band systems.

New York received separate waivers for certain other systems used by FDNY, Department of Environmental Protection (DEP) and Department of Corrections (DOC) that are not integrated with the city’s T-band systems. DEP received an extension until May 1, 2013. FDNY and DOC received a waiver until Dec. 31, 2014.

New York filed the waiver request in June, and the FCC sought comment in August.

Chicago, the nation’s third-largest city, received an extension of the narrowbanding deadline up to and including Jan. 1, 2015. The city has completed narrowbanding for some systems but requests more time for other networks and has prepared budgets and timelines to complete the work.

Philadelphia, the fifth-largest U.S. city, received an extension through Feb. 1, 2014. City officials had requested a deadline of July 1, 2014. Philadelphia filed its waiver request in September.
