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

by Chris Ziegler posted Aug 18th 2009 @ 9:21AM

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.

Meizu looking to CDMA and China-centric 3G with M8 successor

by Chris Ziegler posted Mar 3rd 2009 @ 12:42AM

We've barely had time to digest the fact that real, actual, honest-to-goodness Meizu M8s are now available at the odd retail outlet around the globe, and Meizu's famously colorful CEO is already spouting off about a successor. Talk about a buzzkill, eh? Jack Wong made an off-the-cuff remark in a forum post today about the M9 in two flavors -- M9c for CDMA networks and M9t for China's 3G TD-SCDMA networks -- but beyond that, he's said nothing about specs or availability. Odds are, we can expect a good 18-24 months of teasers, missed launches, and brushes with vaporware status before either model actually launches, so if you had your heart set on an M8, seriously, don't feel bad about taking the plunge.

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

by Darren Murph posted Feb 27th 2009 @ 1:39PM

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!

Telstra kills off CDMA, completes migration to GSM

by Chris Ziegler posted Apr 30th 2008 @ 12:52PM

Oh, come on, Qualcomm, show a little emotion; shed a tear or something! After some two years of planning and urging legacy customers to migrate, Australia's Telstra has flipped a big, red, scary-looking switch somewhere, sending its CDMA network into darkness, never to return. The move effectively obsoletes roughly 3,500 CDMA sites around the country along with what the carrier bills as "redundant equipment" -- a nice little cost savings, no doubt, not to mention the freeing of significant chunks of spectrum for more advanced services. As you might have guessed, Telstra is jumping through these hoops to get customers onto its Next G-branded UMTS network, mirroring a widespread trend away from CDMA-based technologies and toward the GSM roadmap. Globally, it seems like CDMA2000 has years of life left -- but without a shred of major carrier support for the 4G path, its glory days may be numbered.

Qualcomm spat may slow 3G rollout, says Nokia

by Brian White posted May 30th 2007 @ 2:01PM

While Nokia and Qualcomm continue various spats and other legal nonsense to the nth degree, the future of 3G may be at risk. Well, not really -- but Nokia says it could very well slow things down, and mobile WiMAX and other technology that Qualcomm can't claim exclusive license to may be a possible answer. Qualcomm may be in for a bit of shock as the world's transition to 3G technology will mean more and more reluctance to pay any entity royalties. One thing seems clear here -- these two companies don't seem eager to settle on anything these days.

Qualcomm unveils EV-DO Rev B roadmap

by Darren Murph posted Mar 27th 2007 @ 8:24AM

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.

CDMA phones to get ultra cheap, too

by Chris Ziegler posted Nov 27th 2006 @ 1:18AM

Anyone else notice that most of the fanfare surrounding the concept of the almost-free unsubsidized handset has been largely restricted to the GSM camp? Sure, we have occasional CDMA examples like Kyocera's K122 and K132 -- but with all due respect to Kyocera, cooler looking GSM goodies like the MOTOFONE have been generating just a bit more buzz. No worries, though; a handful of scrappy Korean startups are looking to correct the imbalance, committing to deliver $30 handsets utilizing CDMA2000 1x radios (no EV-DO, we're guessing) to India starting in December of this year with other Southeast Asian countries hopping on the bandwagon in '07. According to Rose Telecom, one of the startups involved in the initiative, the phones should take another dive to the $20 mark in 2008. We can almost sense American prepaid MVNOs expressing interest already.

Update: A resourceful reader has pointed out that Motorola's also offering a CDMA variant of the MOTOFONE, which clearly raises the bar for style in the CDMA emerging markets segment. The Korean folks still look to have a slight edge on pricing here -- but with Motorola having suggested that we'll be seeing $15 handsets by '08, they may not for long. [Thanks, Rich]
