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