The Design And Practice Of Residential District TD-SCDMA Network Coverage Program

At present, China mobile increased speed TD-SCDMA the indoor cover construction, has been clear the TD-SCDMA indoor cover construction takes from now on the entire network construction key point, and in local will introduce a frequency band gradually the use. The research indicated that the 3G main business volume originates from the data, but the next massive 3G data traffic will certainly to occur in the indoor, therefore how discusses to further strengthen the indoor network construction, unearths the new indoor network construction plan unceasingly, optimizes the indoor network quality, how moves regarding China to further enhance the core competitiveness under the new 3G environment to have the practical significance.The paper first refers to the 3G indoor cover the characteristic, in view of the indoor cover scene construction structure, the service characteristic, the capacity planning strategy, link budget aspects and so on classification analysis, link loss analysis has carried on the classified introduction. Then introduced the TD-SCDMA different cover solution's characteristic and has carried on the related comparison. Then we have carried on the conventional cover plan characteristic introduction and the existence good and bad points analysis according to the typical scene.And the paper also introduced handovert, the antenna selection, the systematic inside and outside in the TD-SCDMA indoor cover to disturb, the AB frequency band plan principle and the handling characteristics, the electromagnetic environment frequently and so on related standard. Then unified Chongqing local imperial palace temple tianchenhuafu's characteristic to carry on a native place project design and the test orientation lecture. Then the union has carried on a native place project design and the test orientation lecture in Chongqing local imperial palace temple day chen Washington D.C. Chongqing TD-SCDMA the experiment site belongs to the pilot-scale construction, both has the high-level housing, and has the underlying bed housing, but also has the more spacious outdoor quadrangle part, needs the comprehensive solution three cover questions, to constructs the similar scene the indoor cover to have the important meaning, therefore this choice this plot takes the upscale residential district representative solution. This plot concrete solution is:According to tianchenhuafu in Chongqing s synthesis contrastive analysis, the outdoor great base depot satisfies the cover request with difficulty, constructs the indoor cover system actually not to be able purely to satisfy the plot quadrangle leisure region the cover, therefore, uses the indoor distribution system to unify outdoor beautifies antenna's cover strategy.In the tianchenhuafu indoor cover plan introduced that the part has mainly involved in the cover scene outline, the scene the service demand analysis, the power supply way and the construction cost; Has mainly divided into the traditional voice, the videophone, the HSDPA three kind of services regarding the test result, has carried on related test result provision.Finally, unifies the massive TD-SCDMA indoor cover project experience which our earlier period carries on, to the multi-RRU altogether plot plan which involves in the TD-SCDMA indoor cover, the multichannel technology, the space division multiplexing technology, follows the channel technology multiplying technology as well as the indoor cover implementation plan has carried on the use experience subtotal.The paper obtains main achievement:According to regarding the TD-SCDMA indoor cover technology and the plan research, system's introduction indoor had the new excavation innovation regarding mobile communication's 3G indoor cover construction plan, regarding optimized the indoor cover network quality to propose certain solution way.
