With the development of The Times, people in daily life and work encountered in the emergency handling work needs to be improved, in the life and office area of property management security prevention has become the focus. How to deal with various safety issues quickly and effectively has become relevant and important.

Radio from military use evolved into civilian communications greatly convenient and improves the security of people's living and working, and in an emergency and accident occurs, the relevant departments of the staff can be a unified command and scheduling and realize the rapid and timely treatment, become indispensable partner in daily safe and efficient work.

In the actual use process of radio talkie, radio frequency signal of radio talkie is affected by various radio waves, metal structure and other interference and other factors, such as steel, concrete, glass and other materials to the signal shielding and transmission attenuation, resulting in a lot of blind areas, communication voice is not clear. Wireless walkie-talkie communication distance is limited, but also to deal with the security of security has become a major hidden danger.

How to solve the blind area of wireless intercom signal coverage area to meet the user's communication requirements. Improving the quality of communication has become particularly important and become a key point of communication network optimization of wireless intercom system. In a sense, solving the problem of wireless intercom system coverage is not only to improve the communication blind area, but also to improve the communication quality of wireless intercom system, the problem of frequency interference, and the use capacity of system compatible wireless intercom.

Advantages of wireless intercom:

1. Low operating expenses

The system is dedicated to the private network, without monthly call fee, reduces communication cost, improves communication quality and management level, brings benefits to leaders and users, and improves the high-tech image of enterprises.

2. Fast network construction speed and low investment cost

The network structure is simple and universal, and the network costs are economical and cost-effective.

3. Improve efficiency and control cost effectively

Coordinate department management and have supervision and execution strength, provide managers with efficient and convenient tools, and more effectively improve efficiency and control production cost.

4. Emergency and quick response

It can meet the high security needs and guarantee personal safety. It can respond quickly to emergencies, maintain emergency contact with people in potentially dangerous environment, and deal with all kinds of emergencies in a timely manner.

Working principle of wireless intercom:

When the distance between radio talkie A and radio talkie B is relatively far, communication cannot be realized. In the wireless repeater method for pilot frequency signal coverage, when radio A call, radio by emitting frequency to send signals to A repeater receives, the current gain antenna again recently through the link to the repeater, repeater via transmission frequency to send signals to the wireless interphone B, signal transmission by the link to the wireless interphone B nearest antenna.

When radio talkie B sends A message, radio talkie B sends the signal to the relay station to receive through the transmitting frequency, and the relay station sends the signal to radio talkie A through the transmitting frequency. Thus, the communication distance between wireless walkie-talkies is enlarged. The repeater system automatically switches over when both parties talk, and automatically resets after both parties finish speaking. In this way, it is just like the automatic circulatory system of the computer, which saves the trouble of manual guard for the user.

Wireless walkie-talkie is mainly used in public security, civil aviation, transportation, water conservancy, railway, manufacturing, construction, service and other industries. It is used for communication and command and dispatch among group members, so as to improve communication efficiency and improve the rapid response ability to deal with emergencies. As walkie-talkies enter the civil market, people go out to travel, shopping also begins to use wireless walkie-talkies more and more.
