mjsit&t: They must still be operating a 850mhz GSM network in the cities as well as 2100MHZ, if they want the roaming dollar they will.


Newps... that's not the plan currently. UMTS 2100 in cities, GSM 850 outside.

That just wouldn't make sence. It would have to be 850MHz nationwide with WCDMA 2100 in the major cities.

The N80 can do 850/950/1800/1900/WCDMA 2100 if I remember correctly

fact is no one really knows yet what the end network will look like. Seriously a nationwide network of GSM/EDGE and 2100 WCDMA HSPA in major centres.. Having no fall back when in fading WCDMA coverage in a city would be appalling so it is highly proabable that TNZ will build GSM.EDGE nationwide.

Who had a comment about the missing WCDMA 900 phones from the market?

Nokia introduces versatile mobile phones targeted to mid-range market

They'll have to off-load a lot of voice traffic onto 2.1GHz UMTS before they can do that, especially once they lose some of their 900MHz spectrum.

It really depends how much 900MHz spectrum they really need. Vodafone claim they currently use the entire 2x22.5mhz they have MR's for. If they do it's probably in part due to building a network with very low frequency reuse. Many European operators cope with 2x7.5Mhz of 900MHz spectrum and far greater user bases. Vodafone have plenty of 1800MHz GSM spectrum and only make quite limited use of this, it would be very easy to keep the existing GSM capacity by rolling out additional GSM 1800 sites.

Nobody really knows at this stage what's going to happen with existing 800 and 900 MR's but you would have to argue that existing owners of MR's would be unfairly disadvantaged if they were forced to give up any of their existing spectrum. MR's are only a right to use a piece of spectrum and not ownership of that spectrum but trying to force a company to give up spectrum verges on being rather anti competitive.

well, yes, there are plenty of ways of freeing up spectrum, but migrating voice to 2.1 is probably the easiest.

Cunliffe's April cabinet paper gives us a fairly good indication of what's going to happen - Telecom and Vodafone will each lose 2x7.5 MHz when the MRs expire, unless they sell 5MHz before hand. (I'd go for the latter otherwise 7.5MHz will screw up the 5MHz UMTS carriers.) I don't know how binding the cabinet paper is though or what happens next. All the arguments are debated there and in the other renewal documents.
