It based on smart antennas, synchronous CDMA technology, multiuser joint detection, dynamic channel allocation, software radio, relay switching and a varity of hightech. It has many advantages, for example, high spectral efficiency, low cost, asymmetric uplink , downlink channel asymmetry which can be applied to business and so on. The construction of the Indoor distribution system is an important part of the construction of the entire wireless work, different scenarios for the interior design of distributed systems have different requirements, an excellent design of indoor distribution system, not only can avoid wasteful investment, but also can improve the work quality and thus can service customer better, and can create value for clients. The article analysed TDSCDMA technology, work planning process and method. In the rational use of existing cyber source conditions, bining work planning theory, according to the actual situation of Large office buildings DongHai Building and work construction scale, the use of radio propagation prediction model of Large office buildings, formation of TDSCDMA indoor coverage for the planning and design of Large office buildings, indoor TDSCDMA work construction scheme.
