In order to meet the needs of the community's property, security, fire, emergency communication, and ensure that the daily work of management, operation, maintenance and other departments is smooth, safe and efficient, the wireless walkie-talkie communication system provides a convenient and efficient way。Because the radio signal is easily blocked by obstacles such as the indoor walls of community buildings, it is seriously attenuated，The voice signal is interfered with and the communication quality is affected，There are signal blind spots in some areas of indoor coverage，The communication needs of wireless communication and security dispatching for large properties (communities)，Beifeng Company by providing diversified products，Develop reasonable solutions，To provide the community with a set of reliable communication, simple construction, convenient expansion of cost-effective wireless coverage communication scheme。

I. Customer demand analysis

With the development of economy and the improvement of people's living standards, large upscale communities have sprung up like mushrooms。However, due to the multi-building, high floor and complex building structure, there may be some problems in the wireless communication and security dispatch communication of the underground garage, the public area of the building, the fire stairs, the elevator and other areas of the community:

1.High floors, underground garages and complex steel structures shield and attenuate radio signals badly, leading to the existence of communication blind areas.

2.The indoor signal coverage area of community buildings is large, the wireless signal between the buildings can not be completely covered, the signal is unstable, and the call between the buildings is intermittent;

3.With the increase of the number of community users, the original communication system can not meet the increasing needs of users。

4.The battery life is short, which cannot fully meet the all-weather work needs of security personnel;

5.In large communities, the flow of people is large, the environment is noisy, the noise is large, and the staff can not hear the content of the intercom clearly affecting their coordination work;

6.Different positions holding the same walkie-talkie, can not highlight the applicable characteristics of the staff of each position;
