Because building a barrier and crowd density increase caused by the difficulty of work optimization to enhance the establishment of outdoor macro base station has not pletely solve the city39。s weak inadequate indoor coverage and capacity issues in the city. But with the increase in user activity time indoors, they used indoors traffic generated by mobile phones more and more, but because of too dense buildings and personnel, resulting in weak indoor signal coverage and capacity issues inadequate, resulting in dropped calls poor voice quality, switching fails, not the Inter phenomenon, which the work operator39。s image caused great impact, causing great economic losses. Especially the growing promotion of LTE systems, signals his peration than the previous GSM, SCDMA signal peration is even worse, so dense highrise buildings to cover the LTE signal problems caused by more severe. So, to solve the indoor coverage problems, meet the munication needs of users, enhance the munication capabilities of the work, has bee the work operator important things. LTE system as a new generation of munication systems, also known as 4G, it has a high spectrum efficiency, low requirements for industrial control, smart antenna and with a higher download speed, etc. So LTE systems to the construction and promotion of strategic significance for the work operator. The rapid development of the city, building the barrier so dense fast LTE signal attenuation during transmission, resulting in weak signal coverage in large buildings, so that users can enjoy the convenience of indoor LTE system. The construction of LTE discounted distribution system can not only solve the user due to weak signal coverage dropped calls generated by poor voice quality, switching fails, not the Inter and other issues。 and inadequate capacity to solve problems caused by too intensive user generated. Construction LTE discounted distribution system can be wiped away a lot of problems encountered on the road to promote the LTE system, it has great significance for work operators to improve petition in Lee. This design is the use of a distributed antenna system designed Meritus building indoor coverage system, while taking advantage of a road SCDMA to TDLTE and two systems in one. It is through the Meritus location of the building, electromagic environment user traffic, LTE analysis, and technical theory to determ
