摘要
目前TD-SCDMA室内分布系统采用的设计指标主要包括PCCPCHC/I为-3dB、PCCPCH边缘覆盖场强为-85dBm、室内信号泄漏要求在建筑物外10m小于-95dBm三个方面。在城市内基站数量日益增多,站距变小的情况下,TD-SCDMA室内覆盖应根据实际网络情况并结合网络优化来设计,上述标准并不一定能反映网络的实际要求。
The designing objects of TD-SCDMA indoor distributed system include C/I=-3dB, PCCPCH Coverage Level=-85dB, leaked signal level beside buildings at a distance about 10 meters is -95dBm. Because the number of the base station is larger and the distance between stations is smaller, TD-SCDMA indoor coverage designing must be based on the real condition of the network, and objects mentioned above can not reflect the real needs of the network.
