The article presents a technical discussion on narrowbanding private land-mobile radio frequencies using analog frequency modulation (FM) with reduced deviation, Digital Project 25 or 2-slot time division multiple access (TDMA). It also discusses FM improvement factor, FM narrowbanding and static coverage, FM narrowbanding and fading channel coverage and narrowbanding and co-channel interference. The article also mentions that Phase 1 Project 25 radios are good for narrowbanding but its use is not required by the Federal Communications Commission (FCC).
