宽带卫星通信在小型海岛通信中的应用研究

Application of broadband satellite in small island communication

随着国力的增强,我国对于海洋海岛的开发成为必然,海岛通信的重要性凸显。大型岛屿一般使用海底光缆作为主要的通信手段。而对于小型岛屿来说,其具有成本高、系统复杂、工期长等劣势。因而小型岛屿需要一种低成本、快速且容易部署的通信方式,宽带卫星通信能够满足要求。主要介绍了宽带卫星通信的概念、主要技术,分析了宽带卫星通信在海岛通信领域的现状,提出了基于宽带卫星和WiFi的适用于小型海岛的无线接入系统。系统能为小型海岛上的人员提供无线接入、语音通话等服务。本系统将大大减少部署小型海岛通信的成本,提高建设小型海岛通信网络的效率。最后,尝试分析海岛通信的未来发展。

It＇s gradually neccssary for China to develop the sea islands industry with the continuous enhanccment of our national strength. Is-land communication is particularly important under sitiuation of the island ＋ s infrastriuctiure ＋ s growth at a rapid pace. Large islands usually usesubmarine cables as the primary means of communication. However,small islands cannot use it because of high cost,high complexity and longduration of installation. So small islands need a low cost and more easy-to-install communication and broadband satellite to meet the require-ments. This paper introduces the concept and main technology of broadband satellite, analyzes the a p p l ic a t io n statius o f b roa d b an d s a te l l i te in island area, and puts forward an island communication system based on broadband satellite and WiFi （Wireless-Fidelity） applying for small islands. The system can provide wireless access,voice calls and otlier services for residents,researchers and the use of WiFi technology,improves the efficiency of broadband satellites, and reduces the cost o f sm a ll is la n d com m u n ic a t io n s . F in a l ly,thearticle also attempts to analyze the future development of island communications.
