ZTE completes EV-DO Rev. B VoIP call on CDMA2000 system

It seems like just yesterday that Big Red was firing up its EV-DO Rev. A network in America, and already we're seeing signs of life with Rev. B. In all honesty, though, we've known about the next iteration of EV-DO (and the next-next, for that matter) for years now, but said Chinese carrier has just completed what it calls the world's first EV-DO Rev. B VoIP call on its CDMA2000 system. In other words, this is the first time a CDMA carrier has achieved a 9.3Mbps download rate and 5.4Mbps upload rate. The lovely part of this is that ZTE can upgrade from Rev. A to Rev. B without any additional hardware, thus paving the way for a quick commercialization in Q3 2009. Huzzah!

Qualcomm announces improvement in CDMA network capacity

Qualcomm's latest release has left us smothered in technobabble, but frankly, it's a breath of fresh air to not see any sort of vitriol spewed in Nokia's direction. Announced today, the aforesaid outfit has developed a method for improving capacity of CDMA2000 networks; more specifically, its technology will enable "operators to support more than double today's capacity of 35 simultaneous calls in 1.25MHz of spectrum while delivering the same level of voice quality." Unfortunately, the improvements are slated to be featured in Qualcomm's forthcoming Cell Site Modem CSM8xxx-series chipsets, which aren't supposed to go commercial before 2010. Oh future, you seem so far away.

Qualcomm unveils EV-DO Rev B roadmap

While most folks are just getting over the Rev A novelty, it looks like Qualcomm is already prepared to take things to the next level, as it has developed a new chipset that reportedly delivers "9.3Mbps data transfers in field testing." The MSM7850 is being touted as the "industry's first device solution for EV-DO Rev B," hopefully enabling more of those mobile streaming niceties that we all adore. Additionally, Qualcomm stated that there wouldn't be a need for "infrastructure hardware changes" in order to take advantage of the Rev B sweetness, and the chipset itself would be "fully backwards compatible." As for the firm's CSM6800, a "software solution" will purportedly be available by the month's end which will enable "multi-carrier EV-DO Rev B support." Unfortunately, there wasn't a lot of detail surrounding hard dates beyond that, but we can expect the outfit's Rev B-capable MSM7850 to hit testing / sampling later this year, after which the countdown to EV-DO Rev C can officially begin.
