Two-way Radio

There is no professional concept of "the communication distance of the two way radio". the two way radio relies on radio waves to transmit signals, and signals will be interfered with by many factors, which affect the actual communication distance. The communication distance of the two way radio is difficult to determine. The article will introduce the communication distance in an ideal environment and the relative communication distance of the two way radio in different environments.

The Communication Distance of Two Way Radios

The communication distance of the two way radio in an ideal environment

Professional two way radios usually designed with a power of 4W or 5W according to different frequency bands, and the communication distance can reach 8km to 10km in open areas. the communication distance can reach 3 to 5km in urban areas(depending on the communication environment). professional two way radios can be connected to a dedicated trunking network to extend the communication distance over dozens of kilometers even cover the entire city.

Objective communication distance of the two way radio

Hand-held two way radios:

with 5w/4w transmission power: 3km to 5km in urban areas and 8 km to 10 km in open areas;

with 3w/2w transmission power: 1km to 3 km in urban areas and 3 km to 5 km in open areas;

with 1w/0.5w transmission power: 500 meters to 2 km in urban areas and 1km to 3kmin open areas.

Mobile two way radios:

with 50w/40w transmission power: 5 km to 15 km in urban areas and 10 km to 25km in open areas;

with 25w/20w transmission power: 3 km to 10 km in urban areas and 5 km to 15 km in open areas;

with 10w/5w transmission power: 1 km to 5 km in urban areas and 3 km to 8km in open areas.

trunking two way radios: The distance is very long. It is generally used in public safety networks and requires high costs for trunking network infrastructure.

 

Installation of repeaters: The cost of a repeater is relatively high, but the hand-held two way radio and mobile radio can greatly increase the effective communication distance by connecting to the repeater.
