The Research On LTE Indoor Distribution System

With the rapid development of mobile communication technology, a new generation of bandwidth wireless mobile communications technology continues to evolve. LTE as the development direction of information and communication technologies are highly concerned operators and the Government. Due to more modern buildings due to the reinforced concrete skeleton, plus decoration fully enclosed, shielded radio signal attenuation more serious, so call quality is in serious decline. To solve the indoor coverage issue is not ideal, the most effective solution is to install in the building indoor coverage distribution system, and LTE technology can provide a stable communications users building reliable indoor signal, so that users in the room You can enjoy higher quality of communication services.This article distribution system design background covered by the introduction of indoor LTE, described in detail the composition of indoor distribution system includes a source, transmission medium, splitters, couplers, combiners, bridge, attenuators, load, line, antenna and the like. Secondly, the indoor distribution system design. Respectively, from the system-building programs, equipment selection, analysis and calculation of coverage, installation requirements, indoor distribution systems, transmission scheme, power supply and support programs as well as electromagnetic compatibility and electromagnetic protection, and were described in detail, complete description of the overall indoor distribution design situation.By combining specific projects, the Aocheng city Ⅱ of Tianjin. It’s TLE indoor distribution system design and project implementation, so that the second phase of the Aocheng city apartment indoor communication network has been improved significantly, the overall network congestion eased, coverage levels further improved. And it shows that LTE indoor distribution projects can make to enhance the quality of indoor network, indoor coverage overall increase, to solve a large number of poor indoor call quality issues.
