CDMA800与多系统基站共址的干扰保护研究

目前电信业已完成重组和3G牌照的颁发,进入全业务竞争时代,应推动网络节约、高效、环保地运营,然而重组后的3大运营商共拥有6张网络,重复性建设与资源浪费问题日趋严重。为探讨电信运营商共建共享中的技术问题,本文研究了CDMA800与多系统基站共址所需要的干扰保护隔离度,并根据广泛使用的天线型号,研究实际的干扰保护距离及工程实施可行性的措施。

The research of interference isolation needed in co-construction and sharing between CDMA800 system and other systems

Telecom has completed the reorganization and the issuance of 3G hcenses,now telecom is completely going into era of full-service competition,we should promote network with saving,efficient,and environmentally-friendly operation.However,after reorganization, the three major telecom operators have a total of six networks,there are lots of waste of re-construction and natural resources growing problems.To explor the technique in the co-construction and sharing work,this paper research the interference isolation needed in coconstruction of basestation between CDMA800 system and multi-systems.According to a widely used type of antennas,we research the actual isolation distance and implementation of the project feasibility for reference.
