Family Radio Service

Motorola T5320 FRS handheld radio

The Family Radio Service (FRS) is an improved walkie-talkie radio system authorized in the United States since 1996. This personal radio service uses channelized frequencies around 462 and 467 MHz in the ultra high frequency (UHF) band. It does not suffer the interference effects found on citizens' band (CB) at 27 MHz, or the 49 MHz band also used by cordless telephones, toys, and baby monitors. FRS uses frequency modulation (FM) instead of amplitude modulation (AM). Since the UHF band has different radio propagation characteristics, short-range use of FRS may be more predictable than the more powerful license-free radios operating in the HF CB band.

Initially proposed by RadioShack in 1994 for use by families, FRS has also seen significant adoption by business interests, as an unlicensed, low-cost alternative to the business band. New rules issued by the FCC in May 2017 clarify and simplify the overlap between FRS and General Mobile Radio Service (GMRS) radio services.[1]

Worldwide, a number of similar personal radio services exist; these share the characteristics of low power operation in the UHF (or upper VHF) band using FM, and simplified or no end-user licenses. Exact frequency allocations differ, so equipment legal to operate in one country may cause unacceptable interference in another. Radios approved for FRS are not legal to operate anywhere in Europe.

  1. ^ "FCC Part 95 Personal Radio Services Rules Reform" (PDF). Federal Communications Commission. Retrieved May 19, 2017. Paragraphs 51 and 52 list the changes on the FRS / GMRS channels and power restrictions. These modifications are meant to affect previous FRS / GMRS hybrid radios in the United States that were commonly sold to redefine them as FRS radios, since many users that purchase these radios did not know the FCC license requirements. As a result, these users will not require a GMRS license. Radios transmitting higher than the new FRS power restrictions are re-defined as GMRS radios and users will require a GMRS license to use these devices. The changes (channels and power limitations) went into effect on September 28, 2017.
