| 3G service types and increased innovation, indoor coverage becomes the key3G communication. The rapid development of China’s urbanization, high-rise buildings and large increase in traffic density and indoor coverage requirements are also rising.3G services focused on data services, data services, and most users will happen indoors,3G network coverage, capacity, quality, and efficiency has become a key factor in operators to gain competitive advantage. In an urban environment is difficult to predict radio signal propagation characteristics depend on the outdoor station for indoor coverage is very difficult, unable to meet the capacity and communication quality requirements. To improve the3G network quality of service, using indoor coverage technology.By analyzing the operational stage WCDMA market situation, put forward the necessity of WCDMA indoor coverage and analysis of the current stage of Xinjiang Unicom3G indoor coverage status.This paper studies covering WCDMA network application technology. Articles on WCDMA network indoor coverage characteristics were analyzed to study the general principles of indoor coverage, indoor coverage techniques, antenna selection and deployment principles airport scene coverage requirements. Article detailed study of the basic ways indoor coverage, indoor coverage compare the advantages and disadvantages of different ways. Then on the indoor distribution system were studied in detail for WCDMA indoor distribution system design four important areas:indoor propagation model, select the source, the antenna deployment and technical issues related to indoor coverage are discussed. Then it analyzes the typical indoor scenes coverage problem, and finally completed the interior of an airport terminal cover design.Indoor coverage through the study of WCDMA technology, completed the airport terminal interior design. By studying the indoor coverage of the scene, a combination of different indoor coverage technology to guide the class indoor coverage projects. |
