WiFi is not so good as a replacement for wires — the latency is too high. The main contenders seem to be Dirac and AVB, both of which run over Ethernet. Dirac uses entirely ordinary Ethernet, and AVB wants some fancy extensions, which will bump up the price of your switches quite a bit.

For good audio, you want known, controlled latency, preferably with quite precise timing. For live audio, or for a fully convenient replacement for analog cable, you want that known latency to be very short.

And you either need no drops or you need an entire drop + retransmit cycle to fit within your latency. (Hmm, FEC could be used, I suppose — encode packets such that an entire lost packet could be recovered from the preceding packets plus the next couple packets.)

In the professional world, Dante seems to be taking over as the Audio over Ethernet solution.
