That is what the FCC dictates. 83 channels which are 1Mhz wide frequency bands. A channel is a simply another way of saying a frequency band. FM channels are also frequency bands. The difference is you have a channel all to yourself (hopefully) with FM. In spread spektrum you are not on the same channel for more than .4 seconds. One of the ideas behind this is that interference rarely happens accross an entire frequency spectrum. Sadly, this notion is, a priori, wrong. Noise, by its very nature and definition. is a wide spectrum phenomena.
