Do you know what a wireless intercom system is? Then do you know how a wireless intercom system works? Today's society belongs to the Internet era, so slowly there are more and more systems, among which wireless intercom systems are used. How many people know about the intercom system? Today, I will help you to introduce the working method of the wireless intercom system that everyone does not understand.

The wireless intercom system has the characteristics of flexibility, easy operation, fast voice transmission, and economical use. It is the basic means to realize production scheduling automation and management modernization. The wireless intercom system is an independent radio-type dual-frequency two-way automatic repeating communication system, which solves the problem that the communication signal cannot be covered due to factors such as the use of communication range or building structure. , engineering, operation and service personnel, perform their duties in a non-fixed position within the management site.

This system adopts the conventional wireless communication system, press to talk to talk, and respond to every call. In order to achieve no blind spots for communication in the building, overcome the blocking and shielding of wireless signals caused by the building structure and environment, and enable the signal to penetrate from the ground floor to the underground floor, it is necessary to use a relay and forwarding base station to play the role of relay communication. The relay base station works in full-duplex mode, and the user terminal works in half-duplex mode. In order to meet the requirement of 100% communication coverage within the building complex, according to its building structure, use coaxial cable and power divider to lay out multiple antennas-----transmit and receive signals.

This system should not only ensure better call quality, but also avoid the interference of the antenna radiation source to other systems inside the building complex, and strictly implement the standard that the electromagnetic wave interference field strength in the integrated wiring area is not greater than 3V/m.

The above knowledge is how the wireless intercom system works and what is a wireless intercom system, but perhaps it is because of its advantages that many people start to use it.
