无源中继系统在网络覆盖中的应用

Discussion on Application of Passive Relay System to Network Signal Coverage

移动通信蜂窝组网,以基站覆盖“面”,直放站补充覆盖“点”。直放站的引入抬高了蜂窝系统底噪声,加大系统干扰,影响网络质量。在适当场景下,引入无源中继系统可以达到解决弱信号的目的,同时不影响网络质量。本文对无源中继系统可行性进行理论论证与实验论证,提出无源中继实用化的思路。通过对应用案例多角度重点分析,提出无源中继系统的技术要求、应用场景。

In the mobile communication cell network, base station is used to coverage a large area and repeater is used to coverage small area as supplement. Repeater raises up the GSM base noise,increases system interference, effects the network quality. In some suitable condition, passive relay system can solve the problem of weak signals coverage without effects the network quality. The article demonstrates that passive relay system is feasible in theory and by experiment, educes the idea of using it in the GSM network. basing on the analysis of the application example, the technical request and the application location of passive relay system are given.
