Qualcomm expects EVDO RevB in 2007

By Gary R, in , posted: 12-Apr-2006 20:08

When you consider that it was only a few years ago that we were stuck with 9600/14400bps mobile speeds the rate of progress now is quite astounding.

Qualcomm are expecting that the first RevB products will arrive late 2007 and so far they have been pretty accurate with their predictions.

It is interesting that RevB will still use 1.25MHz carriers but the speed capability of each carrier will pumped to 4.9Mbps. You could then (for example) combine 3 x 1.25MHz carriers to achieve 14.7Mbps.

The one thing I do like about Qualcomm is their focus on improving network efficiency in each CDMA release.

Dare I say it - but with the predicted speeds coming out from both CDMA and WCDMA networks WhyMAX? At the rate of change we could be achieving 100Mbps over mobile well within the next 5 years.

Prices keep going down, speeds keep going up. Somethings gotta give at some point? Once there is equivilent speed on mobile to fixed line, and we are running at speeds considered to be 'more than adequate' (today, 10Mbit over mobile could count as that - hypothetically of course), then where will the motivation to invest in faster technology at the same rate be? Will we eventually be downloading say a BLU-RAY sized movie over mobile, becuase its just as cheap and fast? I sure hope so. Heres hoping the bubble just keeps getting bigger, and never gets to bursting point.

Is there really a future for "convergence" or is this simply a term used by PSTN carriers who require a business model so ensure they aren't put out of business by mobile operators? Mobile is the future and I agree that WiMAX probably won't be part of this future when mobile networks will offer true device portability and voice as well.

The main advantage of the WiMAX standard is that it's not dominated by a single vendor like Qualcomm's stuff. The problem with WiMAX seems to be that getting spectrum is a lot harder for operators than envisaged. It's pretty impressive to squeeze out 4.9Mbit/s out of just 1.25MHz. NZ frequencies are auctioned off in 7MHz lots... so 27Mbit/s per management right?

Sorry to be blunt, but I think this is all wireless hype. It started with 3G and now WiMAX, CDMA etc. When the vendors talk about 1Mbps, 100Mbps, or even 300Mbps downlinks, this is the aggregate capacity of the base station or the sector. It is not what each subscriber will get. (Unless you deploy one base station per subscriber.) Let's face it, wireless will never compete heads on with wireline broadband. Its place is for mobile and nomadic usage. JMHO. In addition, the way that NZ spectrum was carved up in smallish chunks does not make it any easier to deploy high speed services. Damn, I will have to write an article about this... :-)

Not sure where you are but at the moment I am getting 1.2Mbps on EVDO Rel0 in the central city at 10:48am. The other day I was getting 1.9Mbps.
