The cell carriers aren't using G711. I haven't seen how much a UMA call takes up, but I'd bet it's less than the 90K of G.711u. UMA basically encapsulates a GSM stream inside of an IPSEC tunnel. EDGE traffic gets up to 100K+ when surfing or downloading files, so I could see a data stream over UMA going up to 150-200K.
If you're talking EVDO data transfers via a femtocell, it could get up to a couple megabits (whatever they're touting EVDO's capability as, plus some overhead for security). -- Bryan Mike Hammett wrote: > I dunno if I'd use anything less than G.711. > > > ---------- > Mike Hammett > Intelligent Computing Solutions > http://www.ics-il.com > > > ----- Original Message ----- > From: "Chuck McCown - 2" <[EMAIL PROTECTED]> > To: "WISPA General List" <[email protected]> > Sent: Sunday, April 06, 2008 11:08 PM > Subject: Re: [WISPA] Femtocells > > >> G.711 require 64kbps plus overhead.
