What is a cluster interphone

Trunk interphone is a kind of communication equipment with intercom function. It is one of the radio communication systems and belongs to the mobile communication system.
Its basic functions include: call, spread spectrum communication, scheduling function, timing signal transmission, etc.
In the current communication environment, the trunking interphone can meet the basic requirements of users in terms of call quality, transmission rate, call distance and storage capacity, and can be applied to personal mobile phones, vehicle-mounted radios and some specific industrial fields. In the wireless trunking communication system, in order to ensure the confidentiality of user information, a dedicated communication link needs to be established between the interphone and the base station.
Wireless trunking communication system can be divided into analog trunking and digital trunking according to the communication mode.
Analog trunking interphone adopts analog communication technology, mainly digital transmitter and analog receiver;
The digital trunking interphone adopts digital communication technology, which can be realized in two ways: What is cluster interphone Trunk interphone is the key equipment of trunking communication system. It is a handheld mobile communication device with intercom function, which is usually used in professional fields such as public security, fire protection and armed police. In these fields, an important feature is that it must have professional call functions, and these call functions are realized through the trunking interphone.
The cluster interphone has the interphone function, so it can achieve seamless communication in the communication process.
At the same time, the trunking interphone also has other communication capabilities, such as emergency communication, emergency broadcasting, vehicle-mounted radio and remote command and dispatching. Market status The walkie-talkie is a portable communication device, which can realize point-to-point communication without wireless communication network.
Due to geographical and time constraints, walkie-talkies cannot be covered in all places, so it is necessary to establish a cluster system through a base station.
The wireless trunking system can connect a group of people, and they can talk at any time no matter where they are. Advantages of cluster interphone The trunking interphone can make the call clearer, faster and smoother because it uses digital communication technology and the system is also very stable. Users can talk anywhere without worrying about the interference of other interphones within the communication range.
When you need to move, you can easily call without changing all devices. The cluster interphone is widely used, involving all walks of life. It can provide fast and high-quality communication services for all departments, effectively solve cross-industry communication problems, and meet the communication needs of different industries.
It has been widely used in different fields.
