The US Congress, through the National Telecommunications and 
Information Agency (NTIA),has mandated all government radio 
operations in the Very High Frequency (VHF) and UltraHigh Frequency 
(UHF) government radio bands be "narrowbanded". The transition 
tonarrowband channel spacing must be accomplished by January 1, 2005 
for the VHF band, andJanuary 1, 2007 for the UHF frequency band. 
Narrowbanding means the changing from 25 kHzchannel spacing to 12.5 
kHz channel spacing. This effectively doubles the number 
ofchannels/frequencies available for government use in the same 
amount of electromagneticspectrum. 

Concurrently, new digital technologies for Land Mobile Radio (LMR) 
are being developed.This is being accomplished jointly among the 
federal government, the telecommunicationsindustry and the 
Association of Public Safety Communications Officials - International
(APCO). The standard for digital LMR radio is known both as "APCO 
Project 25",and the newer Electronics Industry 
Association/Telecommunications Industry Association"EIA/TIA-102" 
standard.

At the recommendation of The Department of Interior (DOI) Radio 
Liaisons, theDepartment decided to adopt the APCO Project 25 digital 
radio standard as the standard forall radio purchases within the DOI. 
The Department has also mandated that all radios /radio systems that 
carry law enforcement traffic must comply with the EIA/TIA-102 
standardand include encryption capabilities / technologies.
