Narrow Banding

Narrow Banding Updates from Homeland Security

The FCC has mandated a change for a more efficient ‘Narrow Band’ spectrum for many emergency response radio systems. This change must have taken effect by January 1, 2013.

The Department of Homeland Security has issued a transitional information document which should aid emergency managers in this process of transition. Lauttamus Security is providing download access to A Practical Guide to Narrowbanding here.

From the introduction….

In December 2004, the Federal Communications Commission (FCC) announced that all non-Federal radio licensees operating 25 kHz systems in the 150-174 MHz and 421-512 MHz bands (VHF and UHF) must migrate to more efficient 12.5 kHz (narrowband) channels by January 1, 2013. Unfortunately, many critical emergency response radio systems used today still operate on 25 kHz radio channels.

The FCC rule applies to both conventional and trunked radio systems and affects all FCC-licensed State and local emergency response radio systems. Wideband radio operation will violate FCC regulations beginning in 2013, and agencies that do not meet the deadline face “enforcement action, including admonishments, monetary forfeitures, and/or license revocation, as appropriate.”

Transitioning to narrowband radio can make some portable, mobile, paging, base-station and repeater radios obsolete, resulting in a loss of coverage or capacity. Emergency response radio system operators across the US have begun implementing these changes, but coordination with interoperability partners is necessary to avoid disruption of crucial communications capabilities.

Lauttaumus Communications is able to help you make the migration to the newer, more efficient narrowband channels. Contact us today to learn more about how we can assist you in this process.
