The Family Radio Service is an improved walkie talkie system, that does not use the Citizens Band (CB) at 27MHz, or the 49MHz band also used by the first cordless phones. FRS also uses FM instead of AM, and has a much greater range.
Technical information
FRS radios are limited to 500 milliwatts in the U.S, according to FCC regulations. Channels 8 to 14 are shared with GMRS, the General Mobile Radio Service. A license is required for those channels only if the power output is over FRS limits, up to GMRS limits.
