The FCC Narrowbanding site is developed by and listed under the Public Safety & Homeland Security Bureau. However, the information provided in the site applies to both public safety/government and business/industrial users.
In December 2004, the FCC mandated that all private LMR users operating between 150 and 512 MHz move to 12.5 kHz narrowband voice channels and highly efficient data channel operations by January 1, 2013. Find out more about Narrowbanding.
