The PSIC Office is conducting a brief survey (less than 3 minutes) to better understand the current status of your narrowband migration. Could you please take a moment to complete our survey?
Overview
“Narrowbanding” refers to a
requirement by the Federal Communications Commission (FCC) that
— on or before January 1, 2013 — all existing licensees on the
VHF and UHF Spectrum implement equipment designed to operate on
channel bandwidths of 12.5 kHz or less or that meets a specific
efficiency standard. Licensees will need to convert or replace
their existing VHF and UHF wideband (25 kHz) systems.
Ultimately equipment will need to operate on bandwidths of 6.25
kHz or less. (Currently no dead-line is set).
Deadline: January 1, 2013 -
Based on FCC Universal Licensing System (ULS) Database As of: January 1, 2012
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 "narrow-band" (12.5 KHz or equivalent)
operation by January 1, 2013.
VHF (150–174 MHz: available nationwide)
UHF (450–470 MHz: available nationwide)
UHF (470–512 MHz: shared with UHF-TV; available only in
11 cities)
After January 1, 2013, licensees not operating at 12.5 KHz efficiency will be in violation of the Commission's rules and could be subject to FCC enforcement action, which may include admonishment, monetary fines, or loss of license.
Narrowbanding Considerations
Consult your public safety leadership and those who maintain your radio systems. Remember to consider "non-voice" radios when reviewing the status of your local radio systems.
Determine if your system needs re-programming or full replacement.
Consider available options to meet the narrowbanding mandate. These include:
Continuing to use analog systems in a narrowband mode
Moving to digital radio systems
Moving to another frequency band such as 700 or 800 MHz
Each option has plusses and minuses. You'll want to get unbiased and competent advice before making these decisions.
Collaborate with neighboring communities to determine their narrowbanding plans. Migrate to narrowbanding in concert with your neighbors in order to assure uninterrupted radio interoperability.
Consider that narrowbanding may cause a slight decrease in the level of system coverage. Conduct a system coverage analysis to determine if there will be a slight decrease in your radio system's level of coverage. Prepare to add towers or other infrastructure to your system if additional coverage is needed.
Modify your FCC licenses to show the new narrowband emission.
Develop a realistic timeline as well as budget of the costs involved. Older systems may need to be completely replaced.
VHF/UHF Narrowbanding Workshop
On January 26, 2011, the Public Safety and Homeland Security Bureau of the FCC conducted a workshop on VHF/UHF narrowbanding to assist licensees in completing the transition to narrowband radio communications by January 1, 2013.
The workshop provides Public Safety licensees with information regarding the narrowbanding transition path, and will include input from federal agencies, equipment manufacturers, and public safety organizations to help ensure timely compliance with the deadline.

FCC: Guidance For Submission Of Requests For Waiver And Other Matters
This Public Notice reminds licensees, frequency coordinators, equipment vendors, and other
interested parties of the Federal Communications Commission’s January 1, 2013 deadline for private land
mobile radio services in the 150-174 MHz and 421-512 MHz (VHF/UHF) bands to migrate to
narrowband (12.5 kHz or narrower) technology.1 It also provides guidance for licensees that intend to
submit requests for waiver of the deadline and sets forth additional information regarding the transition to
narrowband technology.
