FCC Licensing

Action Communications can assist you with your Land Mobile Radio (Part 90) FCC licensing needs.  Whether it is a new application, a renewal or a modification, we work closely with FCC frequency coordinators to obtain or update your license.  We can guide you through all the critical and intricate details in the process.

Why is a license needed?

The radio frequencies used in the transmission of Land Mobile Radios are a shared and limited resource.  Licensing and frequency coordination provide the means to mitigate the over-saturation of frequency utilization and interference.  Licensed users are granted the right to operate their radios in the manner approved in their license, and thus they may seek FCC to take action against violators causing interference.  FCC violations can result in hefty fines that amount in thousands of dollars.

License Expiration

Already have a licenses?  Don’t let it expire!  FCC licenses are good for 10 years.  Generally, the FCC will contact the licensee within 90 days of expiration with a notice of renewal.   Licenses cannot be renewed prior to the 90 days before expiration.  Continued radio usage with an expired licenses is at risk of heavy punitive fines.


The FCC mandated the “Narrowbanding” of the VHF (150-174 MHz) and UHF (450-512 MHz) bands in 2013.  The purpose was to gain more efficiency in the utilization of the RF spectrum in these bands.
As of January 1, 2013, all public safety and industrial/business land mobile radio systems operating in the 150-174 MHz and 421-470 MHz bands were required to cease using 25 kHz efficiency technology and begin using at least 12.5 kHz efficiency technology.FCC Narrowbanding Overview

Digital Operation

As radio users begin to adopt the next generation of radio communications technologies, digital platforms such as:
  • DMR – supported by Hytera, Kenwood, Vertex Standard and Motorola (Mototrbo);
  • NXDN – supported by Kenwood (Nexedge) and Icom (IDAS)
offer improved audio quality, higher efficiency and improved coverage. Licensees with preexisting FCC licenses must modify their licenses to incorporate the digital emissions.  Having prior approval to transmit on a frequency in analog is does not permit the digital transmission on that same frequency.  Digital transmissions must be approved by FCC coordinators and the licensed by modified.
