Narrowbanding for Private Land Mobile Radio Service

Özet

This document specifies the procedures by which forty Private Land Mobile Radio (PLMR) channels, which are located in frequency bands that are allocated primarily for Federal use, are to transition to narrower, more spectrally efficient channels in a process commonly known as "narrowbanding." We take this action because the National Telecommunications and Information Administration (NTIA) has adopted a more rapid narrowbanding schedule in the 150.05-150.8 MHz, the 162.0125-173.2 MHz and 173.4-174 MHz (162-174 MHz), and the 406.1-420 MHz bands (collectively, the Federal bands) than the Commission has required for its licensees.
