According to statistics, used in mobile phones, the number of indoor users greater than the number of outdoor users than 2 times, the users tend to use the mobile phone in the indoor. However 3G band higher signal penetration is weak, it is difficult to realize the depth of indoor coverage.TDSCDMA networkbased data services, while most of the data traffic occurred in the room, so early in the TDSCDMA network construction, the introduction of TDSCDMA indoor hot spots in some indoor distribution system is very necessary. Implementation of indoor coverage projects, buildings traffic can generally be increased times, and at the same time reduce the outdoor network load and expansion pressure, reducing the outdoor network39。s overall interference and improve the quality of network services.1 .TDSCDMA indoor distribution system characteristicsTDSCDMA indoor distribution system pared to other indoor distribution system of the munication system has the following characteristics:(1) TDSCDMA indoor distribution system using smart antenna system coverage, capacity and quality are affected. No shaping gain downlink traffic channel, business channel downlink power 6dB ~~ 8dB lower pared with outdoor coverage. Due to the lack of smart antenna uplink interference is not well controlled.(2) the coverage of the mon channel and the traffic channel be considered separately. Since forming gain smart antenna indoor business channel, so it is a business channel coverage limited system. TDSCDMA pilot power can be flexibly set according to the requirements of, not a fixed value.(3) business coverage is basically the same. Respiratory effects of the TDSCDMA system is not obvious, the business of various rate basically covered the same diameter.(4) support asymmetric data services, according to the traffic up and down to adjust the time slot configuration.(5) working band, big loss, poor signal indoor propagation, deep cover difficult.(6) To reduce indoor, outdoor interference, indoor, outdoor is more suitable for using different frequency Zuwangfangshi.(7) In the indoor distribution area to the outdoor coverage area movement, can not use relay switching, can select only the hard handover.(8) for control system equipment delay. The maximum radius of the TDSCDMA base stations covering , which requires indoor distribution system relay device is not large transmission delay, to ensure that the interference between downlink.(9) using the uplink synchronous technology, improve the technical requirements of the repeater and dry amp.(10) The majority of sources need to introduce a separate GPS antenna, and select a suitable location for installation.2. TDSCDMA indoor distribution system construction principlesTDSCDMA indoor distribution system construction should consider the needs of the coverage, capacity, quality unified. Constrained by the proximity effect, consider a single antenna coverage should be balanced design. And other munication systems between interference and multisystem power sharing 2G indoor distribution system, you need to pay attention to the match. According to the TDSCDMA technology features, this paper presents the following TDSCDMA indoor distribution system construction principles.(1) meet the target area of coverage, capacity, quality demand。(2) to build a prehensive distribution system, using broadband passive devices。(3) To conserve resources, try to share the existing indoor antenna distribution system。(4) to minimize the impact on existing 2G systems。(5) reasonable power configuration to minimize the use of the TDSCDMA dry release。(6) to minimize passive ponents, reduce device insertion loss。(7) considering the construction and operation and maintenance costs。(8) take full account of the system patible, upgrade, expansion capability.According to the above principles，the source selection need to consider the following factors: coverage，capacity and quality requirements of the building, and give due consideration to the longterm business development needs of buildings。 whether the source installation location，whether to meet to take power conditions 。 Third，network conditions，and signal transmission in place around.Coverage, such as switching and interference factors to consider in the des
