1|2

1|2 : Bacolod 3 The throughput of pure ALOHA is optimized when the frames are of the same length. The efficiency of this channel is the probability of successful transmission without any collision. The channel throughput of pure ALOHA is η = Ge −2 G, where G is the number of GWs that wish to access the channel in one frame time, i.e., 1Tfr.
