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.

| - Der Family Radio Service (FRS) ist eine seit 1996 in den USA (wegen der Beliebtheit später auch in Kanada und Mexiko) freigegebene Jedermannfunkanwendung. In Europa grundsätzlich vergleichbar mit dem Freenet, PMR-Funk (PMR446) oder dem SRD-Funk (ehem. LPD). (de)

- FRS (эф-эр-эс) — безлицензионная система персональной подвижной радиосвязи на коротких расстояниях в странах Северной и Южной Америки в диапазоне ультравысоких частот (УВЧ) (англ. Ultra-high frequency, UHF) на частотах около 462 МГц и 467 МГц. Является аналогом европейской системы PMR (Private Mobile Radio). Аналогично последней, это также аналоговая система, использующая тот же диапазон радиоволн (UHF), частотную модуляцию, такую же сравнительно небольшую выходную мощность — до 500 милливатт. (ru)

- 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. 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. None of these radios working with frequencies in the FRS frequency band are legal to operate anywhere in Europe. (en)

En todo el mundo, existen varios servicios de radio personales similares; estos comparten las características de operación de baja potencia en la banda UHF (o VHF superior) usando FM, y licencias de usuario final simplificadas o sin ellas. Las asignaciones de frecuencia exactas difieren, por lo que los equipos que funcionan legalmente en un país pueden causar interferencias inaceptables en otro. Ninguna de estas radios que funcionan con frecuencias en la banda de frecuencia FRS es legal para operar en cualquier lugar de Europa. (es)

Говоря проще, это рации небольшой мощности для связи на сравнительно коротких расстояниях. Никаких лицензий на пользование ими в некоторых странах (например, в США) не требуется. (ru)
