It requires a license in the United States, but some GMRS compatible equipment can be used license-free in Canada. The US GMRS license is ...
FRS radios use narrow-band frequency modulation (NBFM) with a maximum deviation of 2.5 kilohertz. The channels are spaced at 12.5 kilohertz intervals. All 22 channels are shared with GMRS radios. Initially, the FRS radios were limited to 500 milliwatts across all channels. However, after May 18, 2017, the limit is increased to 2 watts on ...
The International Telecommunication Union defines frequency allocation as being of "a given frequency band for the purpose of its use by one or more terrestrial or space radiocommunication services or the radio astronomy service under specified conditions".

This requires either two separate radio channels or channel sharing methods such as time-division duplex (TDD) to carry the two directions of the conversation simultaneously on a single radio frequency. [2] The first two-way radio was an AM-only device introduced by the Galvin Manufacturing Corporation in 1940 for use by the police and military ...
As a result, it was not authorized for use in the GMRS and FRS, only for amateur radio. [5] [6] Baofeng launched a number of other models based on the UV-5R technology, since 2012. Other radios from other Chinese manufacturers have mainly the same range of functions, specs and menu like the UV-5R, for example the Retevis RT5. [7]
