四网协同下室外天馈系统解决方案

Outdoor antenna system solution under the coordination of four networks

当前TD-LTE逐渐步入规模建设轨道,而由于GSM、TD-SCDMA、WLAN和LTE四网的协同发展需要,多系统天馈共用天面的情况非常普遍。本文首先介绍四网协同的大环境下,天馈系统的发展演进过程;同时重点研究天线的内置合路及独立电调下倾特性,评测若干种新型天线的性能及应用场景,进而为解决四网协同下天馈系统建设提供参考依据。

Currently TD-LTE has begun the scale construction, and considering the needs of the coordination of GSM/TD-SCDMA/LTE/WLAN network, multi-system antenna using the same roof of the buildings are very common. This paper first introduces under the four network coordination environment, the development of antenna system evolution, while focusing on the built-in antenna combiner and independent electrical downtilt features, evaluation of several new antenna performance and application scenarios, and then provide a reference to solve the four network coordination outdoor antenna system.
