The FCC has allocated several bands and sets of frequencies for unlicensed use. There are some restrictions to the use of these bandsSee FCC regulations section 95.401 more information.
FRS are a fairly new frequency allocation, the radios are restricted to half a watt with fixed antennas. These frequencies are not to be used with a repeater and only use standard PL privacy Tones.These frequencies may only be used for voice communications.
