Wireless is a different kettle of fish than wired network. Bandwidth is maximum... getting 50M on wireless is like having 50M on a wired lan shared with 50 other people... all surfing. Not quite so bad as if they were streaming, but the instantaneous throughput is all over the place. They reply on lots of resends to get everything there at all. In the language of audio, this reads like drop outs. Opus is probably the only codec that will at least sound like music. On the opus website they have an audio clip with 20% dropouts, it seems to muddle through ok, but not exactly high fidelity :) My 100M wired line when doing nothing else seems to transfer a file at about 40M max. On that I can run 20 bidirectional 16bit/48k pcm with sub 20ms latency (netjack), I haven't played with networking pulse to compare though. (I wouldn't expect much difference) Wireless I can't set much up. -- Len Ovens www.OvenWerks.net
