Abstract
|
With the development of the mobile communications market , especially in the construction of TD-SCDMA, WCDMA, CDMA2000 and other third-generation mobile communication system development , the 3G indoor user traffic will more and more , according to forecasts , more than 90% of the 3G data the business will take place indoors , while the proportion of larger indoor data services . Currently the most effective way to solve the indoor coverage in the country is to build indoor distribution system , thus for indoor terminal communication users to provide a stable , reliable signal , allowing users to enjoy high - quality communication services in indoor . TD-SCDMA is China 's self-developed 3G system , indoor distribution can be shared with existing 2G indoor distribution system , the source has the same type of equipment , such as macro base stations , micro cellular repeater . All mobile communication systems are now exists an inherent problem is that the capacity and interference contradiction . How to maximize the limited frequency resources in space multiplexing, in order to obtain the maximum capacity , the pursuit of the ultimate goal of the mobile communication network planning , so the article at the last hierarchical network planning , the basic idea is to enhance the capacity of design. The purpose of this study is to solve the indoor coverage of the TD-SCDMA network . Focuses on how to solve the TD-SCDMA system in the indoor environment, missing key technologies - smart antenna technology with good network performance and coverage of TD-SCDMA indoor construction projects has certain guiding significance .
