Narrowband Mandate

The FCC narrowband mandate affects all land mobile radio (LMR) users and public safety agencies operating in the VHF (150 - 174 MHz) and UHF (421 - 512 MHz) bands. Radio systems in these bands were previously permitted to utilize "wideband" (25 kHz) channels. To comply with FCC regulations, Part 90 VHF and UHF license holders must convert to "narrowband" (12.5 kHz bandwidth or less) operations by January 1, 2013.

For some systems, the narrowbanding process may only require simple FCC license modifications and equipment reprogramming. But for many licensees, equipment upgrades and coverage redesign may be necessary to comply with FCC regulations and maintain acceptable system performance.

Trott Communications Group offers a complete engineering approach to mandated narrowband conversion and can assist with planning, FCC licensing, equipment evaluation, coverage impact assessment and re-design, specification development, and implementation support. We have completed numerous narrowband projects for our federal, public safety, and commercial clients. The narrowband deadline will be here soon and Trott is available to help navigate the process.
