Public Radio Service (PRS) is a walkie-talkie personal radio service in the People's Republic of China, including Hong Kong and Macau, but excluding Taiwan.
[1] It is similar to the American Family Radio Service (FRS) and PMR446 in the European Union.
The PRS radios use narrow-band frequency modulation (NBFM) with a maximum deviation of 2.5 kHz.
The channels are spaced at 12.5 kHz intervals.
They are limited to 500 milliwatts effective radiated power.
