The development of the communications industry is very fast at present, China mobile, unicom,
telecom competition between the three operators are increasingly bigger. Each operating
manufacturers hope to be able to get more customer resources, and obtain the customer
resource is the most effective way is to do their networks better, let the customer to use
contentment. The current 2 g, 3 g, 4 g networks, there was an obvious high promotion in the
data transmission speed, now everyone through mobile phone network to realize many functions.
Take 3 g network, for instance! In the three operators, China mobile's 3 g network is relatively
less,. Td-scdma in network coverage for the other two operators are more bad, this led directly to a lot of 3 g users in many areas, 3 g network cannot be used, the web services directly

楼主你好、译文如下:
At present the development of the communication industry is extremely rapid, between China Mobile, Unicom, telecom three operators competition is growing. Each of the operating companies hope to get more customers resources, and access to resources in the most effective way is to own customer network to do better, to allow customers to use as one wishes. At present, 2G, 3G, 4G network, in the speed of data transmission is obviously very high increase, now everyone through the mobile phone network to achieve a lot of features. Take the 3G network! In the three operators, China Mobile's 3G network is relatively poor,. TD-SCDMA compared with the other two operators are relatively poor in the network coverage, which led directly to many 3G users in many regions cannot use 3G network, this network service led directly to the China Mobile 3G users to reduce. Network service is poor, the China Mobile 3G's market competitiveness significantly lower than the other two operators. Here the TD-SCDMA indoor coverage analysis, is through the analysis of more in-depth understanding of the mobile 3G network, through analysis, more mastery approach what are the main problems and their existing TD-SCDMA indoor coverage network. In the mobile communications network, indoor distribution system is an important part of the. TD-SCDMA indoor coverage exists for not using smart antenna, delay, the public channel and service channel cover separate etc.. Compared with the GSM system, the loss differences allowed by the TD-SCDMA, covering the worse effect, at the same time, the signal source differences between single and multi channel, these factors need to be considered in the design and construction, reconstruction of TD-SCDMA indoor distribution.本回答被提问者采纳
