Intelecommunications, a frequency band -- sometimes called a band -- refers to a specific range of frequencies in the electromagnetic frequency spectrum assigned to certain applications. This spectrum is divided among ranges fromvery low frequencies(VLF) totremendously high frequencies(THF). Each frequ...

The rule is also very useful when determining the bandwidth of many two way radio communications systems. These use narrow band FM, and it is particularly important that the sidebands do not cause interference to adjacent channels that may be occupied by other users....
