Commercial and residential wireless radio coverage of wireless signal coverage transit project Digital Radio coverage of commercial / hotel // office / residential urban society with the development of civilization, people's living and working environment of security put forward higher requirements for government and public utilities Units for the management of attention, especially in the commercial / hotel / office / residential management, security, and emergency dispatch become the focus of increasing concern. In order to meet social demands, fast and secure timely and effective communication tool has become a security and an essential tool for dealing with emergencies.

Rapid emergency wireless intercom communication property management efficiency and emergencies may bring, has become an indispensable and convenient communication tools. Conventional walkie-talkie single communication through walkie-talkies transmit power of the machine, directly call another walkie-talkie. But with time when using wireless radio call often encounter a lot of noise and call not call each other, this is due to the walkie-talkie radio frequency signal is affected by many factors variety of terrain, terrain and other radio interference, etc. (through the trees decay, steel, concrete, calcium silicon structure, glass and other materials and shielding the signal caused), especially with the increase in the city's commercial / hotel / office / residential building Xun Meng, the floor continues to grow, basement By area, the number of layers, the user use in large buildings and convenient wireless communication is also increasing, conventional walkie-talkie can not guarantee the basement room in these areas, the area of ??the fire corridors, elevators and other air defense region and all smooth intercom signals an urgent need to provide better indoor and outdoor wireless radio signal coverage of the network platform. So, how to solve indoor wireless coverage to meet user requirements, improve network quality, has become increasingly important, also became a focus of the wireless communication network optimization.
