I have linphone working quite well with a WIFI connection - the detail is you have to limit other computers accessing the same AP at the same time. The interesting development is 802.11ac with MU-MIMO - I don't have hardware to test with, but MU-MIMO apparently fixes the VoIP wifi problem. http://en.wikipedia.org/wiki/Multi-user_MIMO Also - 802.11ac should do good beam-forming with devices that support it. http://chimera.labs.oreilly.com/books/1234000001739/ch04.html There is also work on UWB and wavelet radio that if allowed at enough power could do some amazing things. There is a link to a working server that would show the details - but the administration wants to jerk the public around for political purposes and has it redirected to a nag page. http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-02-48A1.pdf ... but you can see it here: http://web.archive.org/web/20111016141207/http://hraunfoss.fcc.gov/edocs_pub... I first learned of wavelet radio in 1984 from a Russian engineer - our government did everything it could to prevent it's use and development. (It is difficult to intercept or jam such signals ) - if we lived in a sane world wifi would be based on this and be much more advanced than it is now. The current regulation limit the power and usefulness to limit competition to protect particular companies. In spite of these roadblocks wifi and UWB has slowly developed.. -------------------------------------------------------------------------------- Karl Schmidt EMail Karl@xtronics.com Transtronics, Inc.
