How far can an intercom communicate? For this question, we first need to understand what is a walkie-talkie? What are the functions of walkie-talkies with different communication methods and specifications?
Walkie-talkies are a communication tool. The biggest feature is that when you press the PTT button, you can transmit content to walkie-talkies operating on the same frequency, allowing more people to grasp timely information and be prepared to respond. If you use mobile phone notifications, you need to notify them one by one. It can be said that walkie-talkies have conveniences that cannot be replaced by other devices.
Mobile phone communications rely on base stations built in cities to achieve coverage. If you are in remote mountains, islands and other places far away from communication base stations, or if there is a geological disaster and the power and communication base stations are damaged, the mobile phone cannot be used. Walkie-talkies can communicate without relying on base station facilities. As long as each other's walkie-talkies have the same frequency, they can communicate, establishing a lifeline in an emergency.
1. Transmission distance of different walkie-talkies
Public walkie-talkies generally refer to walkie-talkies with a transmitting power of no more than 0.5W and operating at designated frequencies. Such walkie-talkies do not need to apply for a radio station license, are exempt from frequency occupancy fees, and can be used immediately after purchase. The communication distance is generally around 1~2KM.
Public network walkie-talkies, also known as IP walkie-talkies, use mobile phone networks (mainly China Telecom's network) to communicate. Public network walkie-talkies can make calls wherever there is a signal from the operator. In theory, nationwide communications can be achieved.
Professional walkie-talkies generally refer to walkie-talkies with a transmitting power of 4~5W and working with radio frequencies specially allocated by the country. The working frequency is specially allocated by the country, and a walkie-talkie corresponding to the working frequency is also required to use it. The communication distance is generally 3~5KM in cities and 5~8KM in plain open areas. The communication distance of our latest MOTOTRBO R7 is generally 3~5KM, and 5~8KM in plain open areas.
Civilian walkie-talkies refer to machines with a transmitting power of no more than 0.5W. They mainly meet applications that do not require strict communication distance, such as restaurants, small gatherings, exhibitions, travel, etc. The price of such machines is relatively low, generally between 240-600. between.
Shortwave walkie-talkies have a very long communication distance. If the external environment permits, this kind of walkie-talkies can communicate across the country or even the world. But users of this kind of walkie-talkie need to have a professional license.
A walkie-talkie used with a repeater station can effectively increase the communication distance. Generally, after adding a repeater station, the communication distance can reach as far as 30 kilometers.
