How Wireless Intercom works

This system uses a conventional wireless communication system, push-to-talk, and respond to every call. In order to achieve no blind areas 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, a relay and forwarding base station is required to play the role of relay communication. The relay base station works in full duplex mode, and the user machine works in half duplex mode.

In order to achieve the requirement of 100% of the internal communication coverage of the building complex, coaxial cables and power splitters are used according to the building structure, and multiple antennas are arranged to transmit and receive signals.

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