johnr: 2G is going nowhere at this stage vodafone NZ turned on sone new 2G sites in 2009

Good to hear. It amazes me more RNC's were not included in the specifications when the XT network was built. One only has to look at the past history of Telecom mobile to note they hardly ever get it right.

Remember the $50 Million they blew when they changed the specs from GSM/UMTS to a dedicated UMTS network deep into the build process. Alcatel-Lucent must have been looking at them sideways.?

So if they had of had GSM/UMTS would they have had fallback to GSM in an outage like they just had ?

Yes that's how it works. They have no GSM, instead it's CDMA which is incompatible. Need a different handset to connect.

Ahh, It sounds like someone said
" its a one in a million chance it won't break so we don't need GSM ! "

Remember the over $100Million Telecom blew in the 90's when they decided to abandon plans (when the project was at a advanced stage) to lay fibre optic cable throughout the Hutt Valley to supply Television to residential households when Rod Deane was the CEO. Another gigantic cock up.

Why is it amazing? Why do you believe Telecom needed more than 2 RNC's?

That would depend on the capacity of the RNCs

People need to build and bridge get over the concept that Telecom should have built a "backup" GSM network. The idea has absolutely no logic or merit.

Ok, fair enough..
So what other backup could you have for fallback/redundancy if a 3G network goes down and you don't have GSM ...

Edit: that is also compatible with all of their 3G phones as well so they could go straight to it on an outage..

You could also say why has Vfone got six and 2 degrees three.?

And the simple answer? Vodafone have six because their older NSN NRC's don't have anywhere near the capacity as the ALU RNC's that Telecom have. More than 2 ALU RNC's are not currently needed to handle XT's current network loads. Vodafone on the other hand couldn't run their network with 2 of their original NSN RNC's.

All data traffic is routed via the RNC's and SGSN and or GGSN before it hits the internet, as data speeds have got faster it puts more load on the network. Bypassing the RNC for data is currently being trialled by some networks and would mean additional RNC's were not needed to handle significant additional data capacity.

What I can't understand is why people are so hung up about the number of RNC's in a network. Greater numbers of RNC's DO NOT make a better network. If Telecom had 6 RNC's they would still only have a single RNC in the South Island. Why? Because there is not the population to support more. The issue that occured would have still affected the South Island and would have taken just as long to repair.

Likewise if Vodafone had suffered the same RNC issue in Chch as Telecom suffered Vodafone would have been without 3G coverage across the South Island also and would have been in the same boat.

I digress, why has 2 degrees got three, I am not bagging Telecom, the network they have built is state of the art but, you cannot have major network outages on a regular basis and expect no damage to your existing brand. It goes without saying that occasionly you do have problems Look at their CDMA network it never seems to give any problems, likewise 2 degrees, to my knowledge they haven't had any serious outages. And remember the XT network only has about 225,000 customers connected to it.
Their CDMA network had over 2 million connections. Go figure.

The point isn't 'how big is your RNC?' but rather 'how many customers are affected if it breaks?'. Vodafone has decided to have fewer customers per RNC rather than risking an outage that affects a large number of customers.

For me, and I've stressed this to the media, the more important point is around fallback capability. If one of our RNCs were to do what Telecom's did, all of our customers would fail over to the slower network. Yes, it would be inconvenient but voice and TXTs would continue, albeit with the associated issues around data speed and possible congestion.
