FCC's Narrowbanding mandate:
All Part 90 VHF (150-174 MHz) and UHF (421-512 MHz) Private Land Mobile Radio (PLMR) system licensees convert from what has been known as "wide-band" (25 KHz) operation to "narrowband" (12.5 KHz or equivalent) operation by January 1, 2013.
Note: The FCC may terminate your license or issue monetary fines if your agency is not in compliance with the FCC narrowbanding requirement.
Oklahoma Narrowbanding Plan
Recognizing that the narrowbanding deadline is fast approaching and that a number of public safety agencies in the state are not in a financial position to meet the mandate by January 1, 2013, OKOHS offered a one-time opportunity in 2011 for Oklahoma public safety agencies to apply for funds from the FY 2010 Interoperable Emergency Communications Grant Program to be used toward the purchase of mobile and portable narrowband-capable equipment.
(Update) OKOHS received an overwhelming amount of requests for assistance. Funding was very limited, but OKOHS made every effort to assist as many applicants as possible. Approximately $379,000 total was awarded to the following agencies for the purchase of narrowband-capable mobile and portable radio equipment:
License Status Tool
The Office of Emergency Communications, along with the Interoperable Communications Technical Assistance Program, recently released a set of online tools enabling public safety officials to check the status of their Narrowband licenses or those of their neighboring agencies. The tool allows public safety officials to run a report and save to an excel file, search for mobiles, search by frequency and search by call sign. The FCC provides the information, and the tool is updated frequently. For best results, search specific locations—there is too much data for broad searches.

Last Update September 2012
Q: What is the final date for wideband operation?
A: All radios must be narrowband by January 1, 2013.
Q: Are we forced to move to 800 MHz?
A: No. Narrowbanding does not require moving to another frequency band.
Q: Will we have to purchase new radios?
A: Depends. Most radios purchased in the last 10 years are already narrowband capable.
Q: Can I operate on a secondary basis if I do not meet the January 1, 2013 deadline?
A: No. The FCC will consider any radio equipment that does not meet the 12.5 kHz efficiency standard to be in violation of FCC rules. You may be subject to daily fines and cancellation of your license if your agency is not in narrowband by January 1, 2013.
Q: Does narrowbanding require me to convert to digital equipment?
A: No. Licensees can operate in either analog or digital formats as long as you operate at 12.5 kHz efficiency.
