GSM rebrands 3G service but claims victory over CDMA prematurely

The GSM Association has rebranded its 3G technology as 3GSM to avoid confusion with CDMA, and is claiming resounding victory over the Qualcomm-controlled rival. This is somewhat premature.

Few doubt that, eventually, the GSM upgrade paths to 3G – which embrace GPRS, EDGE and W-CDMA – will be more dominant than the 2.5G and 3G versions of CDMA, CDMA2000 1xRTT, EV-DO and EV-DV. But the CDMA upgrade path has been far simpler and smoother than the GSM one, so at this stage it is ahead in terms of live 3G networks and actual subscriber numbers. And the delays and technical hiccups in W-CDMA have served to enhance the appeal of CDMA and to guarantee it a longer and stronger life than would have been predicted a few years ago.

The GSM Association, the industry body behind the cellular standard, said this week that 85% of the world's operators have committed to W-CDMA. Its chief Ron Conway was on the offensive – or perhaps the defensive – slamming Australia's Telstra for choosing recently to upgrade to CDMA2000 1X EV-DO for its Mobile Loop services. By 2008, its users will be unable to roam in other countries, he claimed.

He was keen to reassure carriers that the key technical problem with 3GSM, the incompatibility of handsets with GPRS and GSM, was "on the way to being fixed", though this fixing process has already dragged on for far too long.

But despite teething problems, the installed base of GSM will ensure the success of 3GSM in the medium term. It has 850m subscribers worldwide, compared to 150m for CDMA, according to researchers at ABI. At this point, however, CDMA2000 is ahead. Of the 20 live 3G networks in the world, the CDMA-based ones have higher subscriber levels because there have been fewer technical problems, more rapid development of attractive handsets and more appealing pricing.

CDMA is much better

Greetings,

GSM is pretty crappy if you ask me. Its lack of speed, and capacity makes it one of the worse cellular technologies around.

Skip EDGE and go the WCDMA directly instead.

Then again, why not CDMA2000? I use it, and I never missed a call because of the lack of network capacity.

Re: CDMA is much better

EDGE will blow CDMA2000 away, it will also free up more time slots for voice calls that GPRS previously used. Also UMTS will not be everywhere GSM/GPRS currently is, it requires a lot more spectrum.

Greetings,

EDGE's speed is approx. 2x the current GRPS speed... (in theory) isn't it?

Instead of trying to compete with CDMA, why not just blow it away by migrating to WCDMA?

Re: CDMA is much better

EDGE peak speed is 473Kbps, and test by AT&T are averaging 110-130Kbps. GPRS peak is 115Kbps and average is 35-40Kbps. UMTS peak is 2mbps and average should be 200-300kbps. 1xRTT peak is 153Kbps and averages 50-70kbps.

They all have their advantages and dis-advantages, I prefer the codec GSM uses over CDMA.

As I said UMTS requires much more spectrum than current GSM/GPRS or EDGE system will. This spectrum also isn't avaliable to all the carriers until we get some consolidation here in the states, I am not sure about Canada. Also UMTS most likely required more closely spaced towers, and in rural areas and such that can be expensive with not a lot of users. The term 3GSM basically means UMTS in major cities, EDGE in not so major cities and possibly suburbs, while GPRS in rural areas. I also believe to compensate for the lack of spectrum for UMTS US carriers will be purchasing another band, possibly 2100Mhz.
