For multiple access communication systems with high propagation delay (e. g., satellite communication systems), an active repeat random access protocol is proposed.

针对具有长传播时延的多址系统(如卫星通信系统)，提出了主动重发的随机多址协议。

"The concept of being able to access any kind of communication from multiple devices is something fundamental, but so far they've all been kind of clunky -- there hasn't been a carrier-grade solution based on the network itself, " says Charles Gerlach, a director at the consulting firm Mainspring.
