Band Plan

Post by OSCAR-03 »

A Band Plan or band plan is a plan for using a particular band of radio frequencies, that are a portion of the electromagnetic spectrum. Each Band Plan defines the frequency range to be included, how channels are to be defined, and what will be carried on those channels. 

NOTE: The GMRS Band is 70 cm (centimeters)

Typical definitions set forth in a Band Plan are:
  • numbering scheme – which channel numbers or letters (if any) will be assigned
  • center frequencies – how far apart the carrier wave for each channel will be
  • bandwidth and/or deviation – how wide each channel will be
  • spectral mask – how extraneous signals will be attenuated by frequency
  • modulation – what type will be used or are permissible
  • content – what types of information are allowed, such as audio or video, analog or digital
  • licensing – what the procedure will be to obtain a broadcast license
