  • New lease on life: 3GPP2 publishes CDMA2000 1X Advanced spec

    All the next-gen focus seems to be on HSPA+, WiMAX, and LTE these days, but make no mistake, CDMA's alive and well -- and even for the world's present-day CDMA carriers planning to migrate to LTE, legacy cells will be critical assets for years (if not decades) to come. To that end, the CDMA Development Group has announced that the 3GPP2 has published official specifications for CDMA2000 1X Advanced, which bundles a whole bunch of tweaks and enhancements geared toward significantly increasing voice capacity on 1X airwaves (up to four times current capacity, theoretically). This'll give LTE carriers a technology path that should easily carry CDMA through the end of its life without oversaturation, and as an added bonus, it frees up space for more EV-DO spectrum. Perhaps more interestingly, the CDG is talking up simultaneous 1X Voice and EV-DO data -- SVDO -- which should finally close a big gap that EV-DO suffers against its UMTS / HSPA counterparts and deliver on a promise originally intended to be delivered by Qualcomm's EV-DV tech back in the day. 1X Advanced upgrades are expected to be available to carriers in the second half of 2010, and SVDO is anticipated to hit around the same time.

  • EV-DO Revision C becomes "Ultra Mobile Broadband"

    Does a theoretical max of 280Mbps (yes, we said two hundred and frickin' eighty megabits per second) downstream to your phone sound good? Yeah? Then get familiar with this name: "Ultra Mobile Broadband." That's the catchphrase the CDMA Development Group has chosen as its go-to-market term for the set of standards supported by EV-DO Revision C, the latest proposed evolution of CDMA2000 1xEV-DO. Of course, we have to wait for EV-DO Revision B -- with its mere theoretical 73.5Mbps down -- to come and go first, meaning that UMB is lining up for 2Q '07 standard finalization and a commercial introduction some time in the wee months of 2009. Not to be a buzzkill or anything, though, Cingular; we're sure we're going to love your 7.2Mbps HSDPA just fine.[Via Geekzone]
