引言TD网络的大规模建设已迫在眉睫,如何快速高效地建设TD精品网络成为业界关注重点。由于TD采用智能天线等先进技术,TD功放部分必须临近天线口放置,无论是光纤基站或者是馈线基站都必须有室外塔顶单元,这种架构与GSM/WCDMA/CDMA等无线制式存在很大不同。
Introduction The large-scale construction of TD network is imminent. How to construct TD high-quality network quickly and efficiently has become the focus of the industry. Because TD uses advanced technologies such as smart antennas, the TD amplifier must be placed near the antenna port. Both fiber base stations and feeder base stations must have an outdoor overhead unit. This architecture is very different from the wireless standard such as GSM / WCDMA / CDMA .
