I doubt that we're disagreeing on anything of substance. I took
it that Steven's bit about lots more cell sites was based on
his assumption that Telstra was replacing existing CDMA with
GSM. I hadn't made it all that clear that UMTS was to be the
replacement, so any misunderstanding was natural. He certainly
didn't deserve harsh treatment for that. If you have other
issues with Steven, I'm not a party to them.

Different or not, WCDMA is Wideband CDMA. UMTS uses
code-division, so it's CDMA. To say otherwise is like saying
that a catfish isn't a fish because it's a catfish.


Not really. While the air interface of WCDMA is similar to CDMA, even that is
quite a bit different, and the rest of the technology is based on GSM, not
CDMA. The claim that WCDMA is like CDMA is mostly spin by the pro-CDMA
anti-GSM camp.

OK, I see where you're coming from now. I was using the term
generically, because I simply wanted to eliminate timing
advance as a UMTS distance constraint, and didn't want to
unnecessarily complicate things.

Maybe things need to be more specific. WCDMA and CDMA2000 are both
forms of CDMA. CDMA2000 in its various flavors, is usually referred to
as just CDMA. There is a distinction. Both CDMA2000 and WCDMA are
forms of CDMA, although not compatible.

Does QCOM have the patent over WCDMA?

They have a number of CDMA patents, however I don't remember if it is
WCDMA ,or CDMA2000. One if tightly controlled, the other is not.

Qualcom was furious when the Europeans settled on a standard that
didn't require the use of any of the Qualcom patents. One of the
reason for the much more widespread use of GSM is that while there are
patents on some of the chips and implementation, there are no patents
on the underlying technologies. I.E. you can build a GSM BTS or phone
without violating or licensing a single patent.

ATLANTA - DECEMBER 6 - Cingular Wireless today launched its
super-charged wireless network capable of providing customers with
high-speed access to information in a world that has gone mobile.
Customers can use the third-generation (3G) network to access
Cingular BroadbandConnect, which is available to nearly 35 million


Does anyone know how this will compare to VZW's Broadband service?
(VZW's service is great, BTW.)

Only time will tell, but on paper HSDPA looks to be superior.



At this month's Microsoft Road Show in Ft Worth, one presenter quoted claims
of "30% faster than EV-DO". He was repeating what he had been told.

One developer there claimed he downloaded a 2MB file from Microsoft.com in
seven seconds.

I'll be interested in how well it maintains a connection at 70+mph.




Which begs the question.... why would anyone WANT to maintain a
connection at 70+mph?

Not all computer use is interactive, and staying connected at highway speeds
can be useful for unattended operations like up/downloading; e.g.,
transferring a large report file while driving after arriving on an airline
flight.
