Bandplanとは 意味・読み方・使い方

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 license
