Development trend of Wireless Trunking intercom

In the 21st century with the rapid development of information technology, not only profound changes have taken place in communication technology, but also earth-shaking changes have taken place in intercom technology.

The prototype of cluster intercom technology was born in the 1920s, and the real intercom equipment was born in the 1940s, of course, it was still concentrated in military and police use, especially in World War II. The development and popularization of civil intercom equipment was mainly in the 1960s and 1970s. The next 20 years can be described as 20 years of strong growth, intercom, wireless, clustering and other technologies are changing with each passing day, products and technologies have developed at the peak. After the cluster technology is mature, the cluster intercom network can be extended to every corner of the world. However, in an internet era where optical fiber has spread all over the ocean floor and connected the whole world, the rapid development of global information technology has turned the earth into a small village. Nowadays, users only need to pay a very low cost to enjoy the convenience of global communication. The wave of mobile Internet and BYOD is impacting and changing the traditional way of communication. The general trend of trunking communication is IP, mobility, intelligence and terminal diversification.

Intercom technology

It has gone through three main stages: regular intercom, analog trunking intercom, digital trunking intercom. With the development of mobile Internet, we are currently going through public network intercom-> voice and video data intercom. The first three phases are mainly based on wireless technology, while the latter two phases are cluster intercom based on IP technology.

Working mode

Even with the use of wireless technology, it has now evolved from simplex to duplex, and then to mixed intercom, multi-concurrent intercom mode, intercom will be more timely.

Control mode

At present, it is an intelligent era, intelligent communication is also necessary. The intelligent control mode of intercom is bound to make a breakthrough, changing the use mode triggered by PTT key, gesture trigger intercom, voice incentive trigger intercom and other technologies that are more intelligent and more in line with the user experience, which will make the intercom application simpler and more convenient. It's no longer boring.

Generalized terminal

In the past, there were two main kinds of intercom terminals: car desk and hand desk. However, the devices are dedicated and are mainly limited to the implementation of intercom-related functions.

With the development of intelligent operating system and the popularity of intelligent terminals, intercom devices will gradually adopt intelligent operating systems, such as Andriod; intercom terminals show a diversified trend, in addition to mobile, car, personal intelligent terminals (mobile phones, tablets) can also participate in cluster intercom.

Pervasive network

With the gradual transition of cluster intercom technology from wireless technology to IP technology, the region will no longer be limited, and we can still talk about it as much as we want, and there is no need to lay dedicated lines or separate networks.

Of course, the cluster intercom of wireless technology will not disappear, but will be used as a supplement to the IP cluster intercom technology. Wireless trunked intercom network is no longer an isolated island of information, but will be integrated with other communication networks, such as PSTN, PLMN, administrative office phone, etc., this essential change will break the boundaries and make users more convenient. In the end, the intercom will cross the border and is not limited to intercom. It will be integrated into daily communication, and the concept will be weakened.

With the development trend of intercom, Zhuhai Sanrun stands on the shoulder of giant (wireless cluster) and develops a 3G intercom system based on IP technology. The traditional function is not only comparable to that of cluster intercom, but also provides data intercom functions such as video and short message. The system can be used not only in private IP networking network, but also in 3G public network intercom. The terminal can use the current intelligent terminal. It can be an IOS, Andriod phone or tablet. And with independent intellectual property rights of the wireless trunking intercom gateway, so that IP communications, PSTN, PLMN, wireless trunking, wireless broadband and other systems can be interconnected, joint networking. Create and will continue to lead a new era of IP multimedia cluster intercom.
