I have just read a article on the news that the CDMA owned by telstra OZ is going to be phased out. Surely this is not true has anyone heard anything else related to this.

This sounds really weird... Telstra has a strong CDMA network outside the main centres - basically CDMA is the only network outside the big cities in Australia...

I have just read the article you have posted about WCDMA/HSDPA on 850mhz for telstra OZ. I thought that was the frequently there CDMA network ran on. You can't have both on there.

Telstra OZ do but soon it looks like its only going to be GSM/WCDMA/HSDPA same as vodafone NZ. China unicom run a GSM and CDMA network as well.

I bet Vodafone are now hoping that 900Mhz WCDMA becomes a ratified standard.. Imagine how quickly they could roll out 3G coverage to the whole of NZ particularly since they own all of the 900MHz GSM spectrum in NZ so have no shortage and not have to worry about the coverage issues they are experiencing with 2100MHz!

The Telstra decision is very interesting, has anybody read much about coverage for CDMA and WCDMA at 850Mhz? Does it offer identical characteristics?

CDMA is ~824MHz -> ~848MHz or thereabouts.

Telecom may be already in the planning to role out the same sort of thing as they have a 850mhz network here i believe and the infrastructure. Telecom have never said they wouldn't.

I have been told by a friend Telecom reackon this role out will take some serious time so the CDMA roaming agreement will stay in place for time yet, lucky for them!

All things considered as some one who prefers CDMA 1x over GSM or UMTS i think it's a move towards global ability, CDMA still and probably will never have a commanding place in the world market even if it is the better technology.

It will be interesting to see if the coverage ability is the same, in the outback etc the CDMA sites can pump usable 1x signal 120km's, the cockies love it and are concerned that this new network will struggle to match the existing coverage.

This may be the ammo Vodafone needs to take back some market share that they have been loosing to Telecom lately.

I can't see any logic behind Telecom wanting to roll out a 850 WCDMA network when they already have 800 CDMA, EV-DO's upgrade paths in the future give it a very singificant advantage over WCDMA in many aspects. The only aspect it will probably lack in is market share due to a lack of worldwide networks deploying it.

Telstra on the other hand can obviously see huge advantages in having a single standard for their entire network, having multiple technologies and platforms must cause them huge headaches. This move will also be very significant for their Hutchinson investment as well, suddenly they will have a *huge* advantage over any other 3G competitors with the 3/Telstra network covering a significant portion of the country.

Telecom NZ will lose market share with this move by Telstra. Your average pre-pay customer will not be bothered about not being able to roam to Aus but business users will not be happy.

The article I read said the switch to the new network will be a 12-18 month process. I guess that means my business has that time to plan to get our mobiles shifted off CDMA.

True it may not seem logical but look at beta verus VHS, same example of the better Technology suffering due to marketing and global impact.

Telecom have not ruled this out and the head of Mobile said last year that they still can go this way.

Looking from a financial point of view, if your biggest roaming location dosen't support your Network type and your opposition has roaming nationwide in that countyr then how long will it take for Telecom to change their direction.

Prime time for Telstra to make a WCDMA move?

Your comment is very valid, but don't forget that Telecom has never offered roaming (except with a loan handset) in Europe. With high volumes of young New Zealanders travelling to the UK, and Vodafone's extremely comprehensive roaming coverage throughout Europe, you'd think that CDMA's poor global coverage would be hurting Telecom quite a lot, yet they have been happy to persevere with this technology for over four years.

mjsit&t: Prime time for Telstra to make a WCDMA move?


Telecom convert to WCDMA 850 and join forces with Telstra who launch a MNVO and bring the 3 brand to NZ. Never happen? Considering Telecom do own both AMPS A and B bands in NZ is is technically feasible to run a WCDMA 850 and 800Mhz CDMA-EVDO network in parallel?

This looks to be purely a cost cutting exercise from Telstra. Running two network standards in parallel must incur huge costs overhead, let alone Marketing and Sales confusion internally and in the market.

The interesting comments in an article in AustralianIT News were that the cost of delivering a voice call over a CDMA network were 3 x that of GSM and that Telstra spent 4 x the capital per CDMA subscriber than they did for GSM. Telstra would be one of the only operators in the world who could actually make these comparisons.
