The handheld radio can have a call distance of up to 5 kilometers in a flat, open, and accessible environment. This is a small, lightweight, and low-power wireless walkie talkie suitable for handheld or bagged use, making it easy for individuals to carry around and communicate while on the go. Its power generally does not exceed 5W in the VHF frequency band and 4W in the UHF frequency band.

Mobile radio, also known as car walkie talkies, have a common power range of 25W to 50W. The communication distance in urban areas is about 10 kilometers, and it can reach over 20 kilometers in suburbs or plains. It is about 5 kilometers on mountain roads. Mobile radio is usually common in the equipment of self driving tour teams or off-road enthusiasts, after all, compared to ordinary handheld walkie talkies, its call range and transmission and reception performance are more outstanding, providing more favorable communication capabilities for the team.

Generally, the higher the power of a conventional walkie talkie, the greater the communication distance, but most of the power can only reach 05W~5W. No matter how high the power is, it can only be achieved by switching to a relay station. The combination of walkie talkies and relay stations can effectively increase communication distance. Generally, with the addition of relay stations, the communication distance can reach 30 kilometers.If there is network support, such as the installation of repeater or cluster networking, it can significantly increase communication distance and even achieve city wide coverage of communication. It is commonly used in professional fields such as public security, fire protection, and armed police.
