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
EV-DV killed by 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 cant wait for Wimax and Flarion (ofdm) though. thats going to be fun.
