摘要
从分布式覆盖技术概念、组网设备、组网方式等方面对以RRU设备为主体的分布式覆盖技术进行了阐述,从而总结出其技术特点;以山西省临汾市WCDMA试验网为背景,突出了分布式覆盖技术在3G网络建设方案中的应用,并且得出投资、建设周期、安全、扩容性等方面的结论。
In terms of conception, networking equipment and networking manners, distributed coverage technique based on RRU device was expounded and its characteristics were summarized. Taking WCDMA trial network of Linfen city in Shanxi province as background, the application of distributed coverage technique in 3G net construction was introduced and some conclusions of investment, construction period, safety and extendibility were drawn.
