Narrowbanding = Reducing the amount of spectrum a radio uses to transmit a message.

 

In December of 2004, the Federal Communications Commission (FCC) announced requirements to narrowband radio frequencies. We are now quickly approaching the deadline for compliance with that order, January 1st, 2013.

By this date, all radios and radio systems covered by the narrowband order must be compliant with the order. Those failing to be compliant will face a cease and desist order on their radio systems or potentially fines (up to $10,000) from the FCC.

The narrowband order affects license holders:

  • In the Public Safety Conventional (PW) frequency pool; and
  • In the Industrial/Business (IG) pool operating in frequencies between 150-174 MHz and 421-512 MHz.

If your organization holds a license in this frequency range you should check into this further by contacting your radio vendor and/or working with a FCC frequency coordinator.

To begin the transition to narrowband you will need to consider the following points,

  1. Assess/inventory current equipment and radio systems
  2. Plan/budget for new equipment
  3. Apply for new/modified license
  4. Establish timetable for new equipment
  5. Implement your transition plan
  6. Implement new equipment/systems
