The Researching And Engineering Practice Of Indoor Distribution System

In recent years， as telecommunications operator gradually expend the size of the network，the wireless network，s overall coverage has reached a certain level， the user，s perception hasgradually improved as the network slowly getting better. As the user，s perception is graduallyimproved， the user，s requirements are increasingly more higher. On this premise， improvingthe coverage levels indoors and improving the quality of the voice is urgent. The level of indoornetwork and voice quality situation is an important judge whether the network is good. Increasingthe indoor distribution system just can improve the network quality indoors. So indoor distributionsystem is getting more and more important to all operators. Construction of indoor distributionsystem is very necessary and urgent， for meeting the market demand for communications，providing users with high-quality mobile communications services， and improving the marketcompetitiveness of China Mobile， improving enterprise efficiency， consolidating market shareand their own sustainable development and promoting advances in communication technology.In this thesis, the basic theory of indoor distribution system has been introduced，including theconcept, composition, implementation and construction processes of indoor distribution system, etc.Secondly, the design solutions of indoor distribution system including set of GSM and TD-SCDMAtechnology indicators and program design principles to be followed have been researched. Thirdly,by combining the basic situation of a school network environment with the previous theoreticalstudies, the final design of the school indoor distribution system has been given, and the feasibilityof the program has been carried out a detailed avalidation. Finally, the performance of the schoolindoor distribution system has been accepted by approval from the cover effect, data business, callquality and interference test four aspects. At the same time, the quality of construction indoordistribution system specification contains the actual construction process, the host device, standardinstallation requirements antenna, feeder lines, passive components and labels used have beengiven.In this thesis, the construction of the school indoor distribution system has achieved theanticipated effect by combining theoretical research and engineering practice. The design andresearch of indoor distribution system adopted in this thesis has applicability to explore indoordistribution system construction.
