The same frequency simulcast technology solves the problem of communication blind spots and excessive dead zones caused by same frequency interference in wireless communication, and truly realizes seamless coverage of signals and rapid expansion of wireless communication applications.

The problem of regional coverage in the communication of police and fire police

As the size of the city continues to expand, the high-rise buildings in the city are getting higher and higher. At the same time, these high-rise buildings have also seriously hindered the transmission of wireless signals, and many new blind spots have emerged. In addition, as the urban area continues to expand outwards, the monitoring scope also needs to be larger and larger. Therefore, multiple wireless repeaters need to be installed in various areas of the city to meet the needs of communication. If you continue to use the same set of frequencies, there may be multiple wireless signal cross-coverage areas, resulting in inter-frequency interference sources causing intermittent or even complete interruption of communication between the two-way radios. It is more difficult to apply for a new frequency. This is a dilemma.


The same-frequency simulcast technology can establish multiple same-frequency simulcast stations that only require a pair of operating frequencies in the city, fully satisfying the requirement of seamless signal coverage, thereby eliminating the same-frequency interference phenomenon and solving the problem that has always troubled the user unit . The simulcast technology is not only used in public security, fire protection, armed police and other departments, but also covers the management of large tourist attractions, forest fire prevention, port and docks and other departments.


Linear coverage problems in road and rail transportation

The characteristics of linear coverage in road and railway transportation are: the management object extends linearly, and as the line goes from near to far, the wireless signal also changes from strong to weak until the signal is completely interrupted; sometimes the wireless signal of the tunnel and the mountain is also completely interrupted.


In the monitoring area, when major traffic accidents, major public security criminal cases, terrorist bombings, catastrophes, and other major hidden dangers occur in daily maintenance, the line management department needs to obtain information at the first time in order to make emergency command decisions immediately, to control and control disasters And losses are minimized.


Simultaneous broadcasting


The "first time" can be 5 minutes, 50 minutes or 5 hours. The longer the time, the more serious the consequences, and the results will be very different. At the same time, the cost of manpower and material resources invested will also be far away.


The simulcast technology can set the same-frequency forwarding base station on the monitored roads, railway stations or tunnels so that the intercom, the intercom and the management department will not have the same-frequency interference. In this way, when an emergency occurs, you can be notified quickly and in a timely manner, so that various departments can make an immediate emergency response.


Applicability of the same frequency and simulcast wireless communication system

The same frequency simulcast wireless communication system is suitable for: conventional wireless communication of police; wireless communication command of public security fire protection; wireless communication of highway traffic police; wireless communication dispatch of railway, highway and oil pipeline extension section; public security train, military depot, automobile transportation team, forest fire prevention Department of wireless communications and any industry requiring emergency wireless communications.


The simulcast technology scientifically integrates various existing link resources (wireless, wired, E1, digital circuits, IP, satellite, etc.) of the customer, and achieves a multiplication effect with relatively small resource occupation and capital investment, becoming a wireless dedicated A highlight of network technology development and technological progress.
