目前卫星通信正从大型终端的少数大容量业务向使用许多小型终端的更多用户定向分配网络方向发展,这种发展最终结果可能就是手表式通信机。小型终端网络有若干共同点: 一般均采用星形网络结构,这样做发射功率和接收灵敏度要求低。小型终端之间的通信为双跳卫星线路结构。
Satellite communications are now moving from a small number of large-capacity end-user terminals to more subscribers using many smaller terminals for targeted distribution of network direction. The end result of this development may be the watch-type communication machine. Small terminal networks have a number of things in common: Star networks are generally used structure, so do not require low transmit power and receiver sensitivity. Communication between small terminals is a double hop satellite line structure.
