Qualcomm Suspends EV-DV Development
Mar 4, 2005, 4:45 PM by (staff)
Due to a lack of interest from carriers, not just in the US but world-wide, Qualcomm has suspended development of EV-DV chipsets. EV-DV is a high speed data standard designed as a faster, more efficient alternative to EV-DO on CDMA 2000 networks. However carriers have instead chosen to launch EV-DO networks since hardware for them is available today, and the next revision of EV-DO (rev. A) adds many of the speed boosts and features that EV-DV offers while maintaining backwards compatibility. Qualcomm has not pronounced EV-DV dead yet, maintaining it will monitor the market for interest in the standard.

Kind of sad
It's crazy we've come to a point in technological advancement where someone has developed the next best thing and people say, "Eh, what we have is fast enough." i realize this is an oversimplification, but still true.
actually REV A is a lot better then DV
...
EV-DV killed by DO
there was no point in EV-DV because the operators want to do VoIP via DO.
The real story here is that operators want a full IP network and an air interface with low latency to do VoIP.
The other story is the fact that Qualcomm has reduced the latency on EV-DO enough so people think VoIP over EV-DO might be doable in the not so distant future.
I beleive latency on the latest EV-DO release (the one sprint will deploy) is sub 100 ms. That is huge compared to the 300 to 500 ms it is with 1xrtt and its going to get better.

I think I get what you're saying, but what exactly do you mean by "low latency." Thanks in advance.

sprint will be doing REV A also which is under 100ms and faster data speeds then REV O.
i cant wait for Wimax and Flarion (ofdm) though. thats going to be fun.
