EDGE and VOIP
No one can blame anyone to be cautious abot VOIP over EDGE. It's a joke. I've tested every possibility to use VOIP over mobile network here in Latvia, and our development of mobile technology has leapfrogged everything in US in recent years. Starting from plain GPRS, then EDGE. It wasn't feasible. 3G brought a partial usability: I at least could hear what the other party says, and the other party was able to hear what I say, without lost words and sentences. But not in duplex, not simultaneously. Only HSDPA enables full guaranteed duplex VOIP communication over mobile network. Not because of greater speed, but because this speed makes possible a caching of data that compensates for very high latency that's still inevitably here, and voice signal fully gets to the other side, though a bit delayed. WIFI has at least 1/10 of latency, even when we're talking about HSDPA. I don't have much of experience to argue about other subjects of this article.
