With the constant development of mobile network, the priority of the network coverage has changed from the breadth to the depth. As the antenna of indoor disturbed system households too difficult, the QoS of indoor signal can't be guaranteed. The pilot pollution of indoor disturbed system which has been built is difficult to solve. Based on this problem, CAT5 repeater is introduced by specific cases. While the technical highlights and application model of CAT5 repeater are discussed.%随着移动网络规模的不断发展,网络覆盖重点已由广覆盖向深度覆盖转变。由于室分天线入户较困难,导致室内信号覆盖效果无法保证,已建室分系统的导频污染等问题较难解决。针对这一问题,通过具体的案例介绍了五类线直放站,并对五类线直放站的技术亮点和应用模式进行了探讨。
