Study On The Solution For TD-SCDMA Indoor Coverage System

With the successful restructuring of China’s telecommunications industry, the three mobile operators have launched full-service telecommunications qualifications and abilities. In order to ensure competition in the future to obtain greater advantages, the three operators have launched3G services rich. The most important3G business users focused on indoor, therefore, a good indoor coverage for mobile operators to develop new users, retain old user focus and key. Based on this background, the paper selected China Mobile’s TD-SCDMA network indoor coverage solutions for the research on TD-SCDMA indoor coverage in detail the theory and technology research.Based on the characteristics of TD-SCDMA indoor distribution system construction and features indoor wireless signal propagation environment, combined with the subway and college application case scenario, the paper discusses in detail the construction process and strategy TD-SCDMA indoor coverage systems. Provides a theoretical basis and the corresponding solutions for China Mobile’s TD-SCDMA network construction interior. The main work of this thesis are:(1) TD-SCDMA clear purpose indoor distribution system construction; study the characteristics of TD-SCDMA indoor wireless propagation environment, and establish the corresponding propagation models; gives the TD-SCDMA indoor distribution system of four access methods; identified TD-SCDMA indoor distribution system construction design process. Detailed discussion of the TD-SCDMA indoor coverage commonly used networking solutions and multi-play indoor distribution system design.(2) Select the Beijing subway Shenyang Institute of Physical Education both TD-SCDMA indoor typical application scenarios for the case, analyzes the characteristics subway and universities of the two scenarios, and the construction of the corresponding TD-SCDMA indoor distribution system was described in detail.(3) TD-SCDMA solution uses a variety of advanced technology and networking concepts, solve the problem of TD-SCDMA indoor coverage.
