The indoor signal covers the technology and application study
ABSTRACT
The capital is designed is to study the indoor signal covers the technology and application study mainly. Do more thorough analysis and contrast by the fact that network various covers a technology to the beehive , point out that technology developing direction. Suggest that indoor being unlike a type several kinds distributes system , study whose made up of , scheme and apply a characteristic. Discuss that system designs problem combining with project practice. To multisystem, indoor synthesis covers a technology and manages go along studying.
Have done the basis introducing that system covers systematically in indoor introducing single communication system's, as structure from the angle that the indoor wireless signal transfers to indoor distribution system. And, to displacement, in communication system, main displacement makes style having assumed a summary. Then we indoor coverage system based on the composition of indoor coverage system design, including the design basis for design, engineering scale, electromagnetic radiation protection, equipment technical indicators, project planning, Traffic and economic analysis, the use of mathematical , Physics, microwave, signal processing, and other knowledge, personally designed a room distribution system. Through the system and the opening and commissioning of the repeater and the opening of a certain degree of understanding, in the opening of the steps, specific debugging, straight-Performance indicators to monitor the set of parameters and debugging, feel that the time and the importance of combining theory . Carry out analysis , get deep cognition from practice middle on the effect covering effect testing and communicating by phone. Analysis and system being in progress to namely synthetical multisystem small side door road construction coverage introduce an at last.
Key words： Indoor distribution system Design Debug Cover synthetically
