摘要
提出了一种基于LTE的战术无线宽带通信系统,可为半径为8 km范围的战术区域提供稳定的无线宽带通信信号覆盖,实现面向多种战术应用的宽带数据传输和集群话音、视频通话功能。对系统功能和性能进行了试验验证,试验结果显示,在MIMO天线采用空间分集设置条件下,单基站可在半径为8 km的区域内同时提供上行宽带约15 Mb/s、下行宽带约28 Mb/s的数据传输能力以及多路RS-422串口数据传输能力,并可在数据传输的同时进行多种模式的战术集群通话,满足战术通信业务需求。
A tactical wireless wideband communication system based on Long Term Evolution （LTE） technology is proposed in this paper, which can provide a stable communication network of 8 km coverage radius and support various tactical applications such as data transmission, trunking call and video call. The functionality ＆ performance of the system are validated by field experiments. Experimental results show that under the condition of setting antenna in spatial diversity receiving mode, within 8 km radius coverage area, a single base station provides sim- ultaneously up-link 15 Mb/s ＆ down-link 28 Mb/s data transmission rate, multichannel RS-422 data transmission capability, and multi-mode tactical trunking call capability.
