WebNov 13, 2015 · The FCC's Table of Frequency Allocations is codified at Section 2.106 of the Commission's Rules. For the allocation of frequencies the ITU has divided the world into … A radio band is a small contiguous section of the radio spectrum frequencies, in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands. For example, broadcasting, mobile radio, or navigation devices, will be allocated in non-overlapping ranges of frequencies.
