过去几年中,人们对天线口径非常小的地球站(VSAT)卫星数据网领域的兴趣不断增加,并展开了研究。VSAT网以用户为前提,采用低价的、天线较小(一般小于2米)的地球站,为地域上分散的远地点之间提供直接交互式数据服务。这种以卫星为基础的广域网与普通地面技术相比,在经济上和运行上有几项潜在的优势。由于当前卫星和地面技术的综合发展,使这些 In the past few years, there has been an increasing interest in the field of satellite data networks for very small antenna stations (VSATs) and studies have been conducted. Based on users, VSAT uses low-cost, smaller antennae (typically less than 2 meters) to provide direct interactive data services between geographically dispersed apogee sites. This satellite-based WAN has several potential advantages both economically and operationally compared to conventional ground-based technologies. Due to the combined development of current satellite and terrestrial technologies, these are made
