走向宽带化的VSAT卫星通信

受数据音频视频广播、计算机卫星宽带交互接入和音视频会议等业务的推动，VSAT卫星通信网向宽带业务发展巳成为必然趋势。分别对应以上业务的VSAT卫星通信网也日益趋于融合成一个统一的宽带VSAT通信网。发展宽带VSAT通信网的关键技术涉及到宽带数据广播、宽带多址接入、卫星通信规程、网络综合管理和宽带虚拟子网等。

VSAT Satellite Communication toward Broadband

Pushed by services of data/audio/video broadcasting, interconnection with computer networks and audio/video conference, VSAT is now irreversibly developing to provide broadband services. The separate VSAT satellite communication networks, which provide above services respectively, are converging into a consolidated broadband VSAT networks. The key technologies involved in developing broadband VSAT networks include broadband data broadcasting, broadband multiple access, satellite communication protocol, integrated network management and broadband virtual subnetworks.
