This discussion is going around the place at the mo especially since Telstra Aussie are looking to close CDMA 2000 over there. Well thats the idiot CEOs plan, the Govt have told them to delay it as many interest groups are submitting to get a repreive.

I have heard the CDMA subscriber base has been out growing GSM and even WCDMA with Telstra?

Any way if Telstra does close the network, wouldn't it be of great benefit for Telecom to build a sister network to CDMA 2000 in NZ and migrate it's Voice and some data clients over to WCDMA and then ramp up it's EVDO 0 then Rev A, B then C to nationwide network to provide a decent nationwide wirless broadband network??

Can this be done? i have heard yes but then iam most likely wrong.

The long term handset choice and roaming alone with WCDMA would give Telecom customers all the benefits that Voda's 3g WCDMA clients have but with better coverage, 850 is of course going to better than 2100 or in the future 900mhz.

Aledgidly the brass at Telecom reackon no??? Wonder if thats the right decision to make or are Telecom just waiting to see how Voda's WCDMA roll out and HSDPA goes, plus the final closure decision on Aussies CDMA?

I would put more money on seeing Telecom follow Sprints evolution path, both for mobile and a nation wide mobile broadband network due the close relationship the pair are currently involved in. As Telecom has said before, they are happy with the performance of their CDMA network. To me this would suggest Telecom is waiting for dual chip phones (CDMA/WCDMA)?

Time will tell, although the other speculation I have heard is Telecom getting together with TCL to build a network as you are talking about. I doubt this, but don’t put it pass either party.

Even though we don't know what Telecom's future direction is I'd still put my money on any future Telecom WCDMA network being a joint Hutch/TelstraClear/Telecom project with the 3 networks each deploying MVNO's under their own brands. Telecom are very clear that their very significant investment in 3 Australia is strategic, it would seem the logic behind this is to stay in bed with both both Hutch and Telstra. A joint transtasman network for both companies would be extremely powerful for all involved especially since Vodafone's old plans to effectivaly crate one big trans tasman network with are now history.

The same scuttlebug is what i have heard and the media outlets are talking about.

TCL/Hutch and TNZ together in one big network would be interesting but Telecom aren't one for not having control of everything.

They are talking up Wimax at the mo as a solution, dual chip CDMA/WCDMA phones are not too far away though and as l;ong as they are cool i am sure will be the answr for Telecom. I have noted Several European countries are building CDMA 450 networks with the intention of EVDO/A/B/C, seems that WCDMA is not everyones first choice.

I read somewhere that the uptake for CDMA was a lot higher than GSM/WCDMA. The eastern european countries really seem to be getting in on it. At least one was starting with Rev A

Believe it or not ~ Close to 80% of the entire global 3G user base is on CDMA2000. By 2008 it is expected that 231M people will be on EVDO and 200M will be on HSDPA.

The convergence point for mobile broadband will be the introduction of OFDM which is expected to be adopted by both GSM and CDMA operators.

450MHz EVDO is currently being trialled in Finland and Norway

It seems to me that Telecom are already using the right 3G technology. Why would you change?

OFDM is a new one to me... *quickly checks google* so would that be used for data only or voice and data... one worldwide standard sounds good.

I agree with you, why change, CDMA and EVDO A/B/C are going to be the superior choices in the future.

All CDMA operators need to do is get their roaming sorted for voice and especially data and also some of the messaging services such as PXT and TXT.

Once these are sorted CDMA 2000 is the choice for networks wanting the most bang for their buck!!

OFDM would be used for both voice and data. Ultimately circuit voice will disappear and all voice will be like VoIP.

OFDM was developed by Flarion who were acquired by Qualcomm.

Qualcomm tried to push it through the IEEE as 802.20.

Interesting info on it at Wikipedia:
http://en.wikipedia.org/wiki/802.20

It would seem development has halted. This is very similar to WiMax which Sprint have said they will be using

Correct but that will not stop development of OFDM. Expect to see it pop up as an ITU or 3GPP standard.

I'm presuming that includes 1xRTT customers which is a bit of a stretch to call 3G don't you think?

Latest figures I've seen is ~70 million WCDMA (June 06) vs ~36 million EVDO (August 06), growing at 3.5 million a month and 6 million a quarter respectively.

With GSM/WCDMA having an 82% share of the mobile market (up from 78.3% a year ago), and with GSM/WCDMA subscriptions growing at 10x CDMA during 1H 2006, the future is looking pretty good for WCDMA....

I don't think it's a stretch. AFAIK, ITU standards say 1xRTT is 3G.

Back to your point. GSM is not the same as WCDMA. And not all GSM subscriptions are WCDMA subscriptions - some networks don't even have WCDMA.

Yes, I got that press release last night and couldn't be bothered posting - too much hype.

GSM != WCDMA

They (ITU) also say that EDGE qualifies, but you won't see that counted as 3G. I'd consider the inclusion of 1x & EDGE to be "creative accounting".

Quite correct - but I was comparing apples with apples. Current figures were WCDMA & EVDO only, and market share was GSM/WCDMA & the CDMA2000 family.
