Interphone is a terminal device for cluster communication
The walkie talkie covers a wide range. Here, we will collectively refer to radio communication equipment operating in the ultra short wave frequency band (VHF 30-300 MHz, UHF 300-3000 MHz) as radio walkie talkies. In fact, according to relevant national standards, they should be referred to as ultra short wave FM radio telephones. People usually refer to handheld wireless telephones with small power and size as "walkie talkies", which were previously referred to as "walkie talkies" or "walkie talkies"; A wireless telephone with high power and large volume that can be installed in vehicles (ships) or fixed for use is called a "radio", such as a car mounted station (car mounted machine), a ship mounted station, a fixed station, a base station, a transfer station, etc.
