SECURITY BUREAU PROVIDE SUPPLEMENTAL GUIDANCE FOR LICENSEES IN THE 
150-174 MHz AND 421-512 MHz BANDS SEEKING WAIVERS OF THE JANUARY 1, 2013 
NARROWBANDING DEADLINE
This Public Notice provides supplemental guidance to licensees seeking waivers of the Federal 
Communications Commission’s January 1, 2013 deadline for private land mobile radio systems in the 
150-174 MHz and 421-512 MHz (VHF/UHF) bands to migrate to narrowband (12.5 kHz or narrower) 
technology.1  
Specifically, we recommend that licensees seeking waivers ensure that their submissions include, 
or are amended to include, a definitive list of the frequencies for which they are seeking a waiver, a list of 
frequencies that will be relinquished (if applicable, e.g., if the licensee intends to migrate to the 700 MHz 
or 800 MHz band and relinquish VHF/UHF spectrum), and representations from all licensees covered by 
the waiver request that they have committed to take any actions that form the basis for the waiver 
justification.  
Additional Narrowbanding Information
The Wireless Telecommunications Bureau, Public Safety and Homeland Security Bureau, and 
Office of Engineering and Technology have issued prior guidance by Public Notice regarding 
narrowbanding migration, compliance, and waiver requests.2 In addition, detailed information and
