Usage is divided into hand-held, vehicle (ship, machine) loading, fixed, and re-transmission.
Handheld intercom <br> <br> This is a small size, light weight, low power walkie-talkies, handheld or bag adapted to facilitate personal portable, capable of communicating in the road link, which power is generally VHF band Not more than 5W, UHF band does not exceed 4W. However, there are a few models whose power VHF is 6W and UHF is 5W, such as IC-T7H (VHF) up to 6W. The communication distance can reach up to 5 km without obstacles. With the support of wireless communication network, the communication distance through the relay station can reach more than 10 kilometers. The machine is suitable for close communication between various mobile users. In the series of radiotelephones, the number and variety of applications for handheld radio “walkie-talkies†is the largest, accounting for more than 80%.
<br> <br> wireless carrier which is a walkie-talkie can be mounted directly on a vehicle powered by a power on vehicles, ships, aircraft and other vehicles, and vehicles using <boats, aircraft> antenna walkie talkie, mainly For transportation, production scheduling, security command and other services. Its large size, power is not less than 10W, generally 25W. The maximum power is 56W for VHF and 50W for UHF. There are also individual radio stations that have a power of 75W (IC-VX8000) in a certain frequency band. The power of the radio station is 13.8V, and the communication distance can reach more than 20km. In the wireless communication network, the communication distance through the relay station is obviously increased and can reach several tens of kilometers.
