Gigahertz Frequencies This lesson discusses 2.4 the gigahertz frequency; which has 14 channels. Only channels 1-11 can be used in the USA as the remaining channels are closed off for government use. Typically, we use 1, 6 or 11 as channels need separations between them to be the most efficient. Participants also learn about the 5 gigahertz frequency, which is more expansive and has more channels. Some of these channel have restrictions and special training is needed to set them up.
