You should be getting much higher rates. At the default of 500 kilobits per second bit rate for GMSK, I can transfer, using scp, a 10 megabyte file in 3:32, or 212 seconds, for a effective throughput of about 49 kilobytes per second, or about 386 kilobits per second. That's shows about 23% overhead in terms of modulation, packet overhead, protocol overhead, collisions, and probably most significantly, the overhead from relinquishing the channel while the other end is sending ACKs. If you had the similar efficiency as the above, you'd be getting around 600-700 kilobits per second. Are you sure your figures aren't kilobytes instead? -Johnathan _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
