摘要
由于受到客观条件限制,偏远岛屿和山区无法通过光通信、微波等传统传输方式部署4G无线网络,严重影响了偏远乡村无线通信的发展。文章对不同轨道类型卫星特点、甚小孔径终端(Very Small Aperture Terminal,VSAT)卫星通信技术以及4G无线网络与VSAT卫星系统进行适配研究,针对卫星系统传输带宽小、时延大等技术瓶颈,通过卫星轨道和频段选择、无线基站带宽控制、卫星系统服务质量(Quality of Service,QoS)部署、卫星系统带宽共享等方式,开发了一套基于VSAT卫星通信技术的4G无线网络部署的方案。文章研究方案成功地在偏远岛屿和山区进行规模化部署。
Due to the limitations of objective conditions,remote islands and mountain areas cannot deploy 4G wireless networks by traditional transmission methods such as optical communication and microwave,which seriously affects the development of wireless communication in remote villages.In this paper,the characteristics of different orbital types of satellites,VSAT satellite communication technology and the adaptation of 4G wireless network to VSAT satellite system are studied.In view of the small transmission bandwidth and large delay of satellite system,through satellite orbit and frequency band selection,wireless base station bandwidth control,QoS deployment,satellite system bandwidth sharing,etc.This paper develops a solution of 4G wireless network deployment scheme based on VSAT satellite communication technology.This solution has been successfully scaled up in remote islands and mountain areas.
