摘要 随着移动通信的发展,第三代的移动通信技术必将在室内广泛使用,但由于其工作频段为2GHz,因此TD-SCDMA网络有一个缺点:电波绕射能力比较差。这样就带来一个弊端,即TD-SCDMA信号要实现深层次的覆盖比较困难。现代建筑中不可避免的要用到金属材料、混凝土等材料,都对无线信号有很强的屏蔽作用,因此,运营商采用了"室内分布系统"来解决上述问题。本文将对TD-SCDMA建设中,其室内分布系统在网络和技术方面的需求及总体设计规划进行分析。 With the development of mobile communication, the third generation of mobile communication technology will be widely used in indoor, but because of its working frequency is 2GHz, so TD-SCDMA network has a shortcoming:radio wave diffraction ability is rather poor. It leads to a disadvantage, namely TD-SCDMA signal is difficult to achieve the deep cover. The modern architecture inevitably to use metal materials, concrete and other materials, has a shielding effect on the wireless signal, therefore, operators using"indoor distribution system"to solve the problems mentioned above. Based on the construction of TD-SCDMA, to analyze the demand and the overall design and planning of the indoor distribution system in the network and technical aspects.
