摘　　要：主要介绍了一种在不影响用户上网的前提下利用五类线将以太网信号和3G信号同时传输到用户家庭的室内覆盖接入系统。同时验证了五类线上传输3G中频信号和以太网数据信号的可行性,并对两信号间相互干扰引起的系统性能损失进行了分析。经测试分析验证,所提接入系统可以直接利用驻地网资源和用户资源进行室内信号覆盖,实现方便,可利用价值高。In this paper, a family of indoor coverage access system is described with category Five Line to the simultaneous transmission Ethernet signal and Third Generation signals without affecting the users online. At the same time, it is feasible to use the Five Lines to transmit 3G signals and Ethernet data signal, and the two signal caused by mutual interference performance loss are analyzed. The access system directly uses the resident network re- source and user resource of indoor signal coverage, and has easy implementation and high utilization value.
