Just out of interest, as I see Telecom only have one in Chch and one in Auckland for the whole country, but apparently Vodafone have 6.

a bit off topic but from the Gen-i CEO Webcast earlier Today, IIRC One of the major UK providers only has 4 RNC's to cover the entire network going across the UK,

RNCs cost a few million each but they're only one component in the network. A key component for sure but still only one part.

Cheers

Question for John: Do you think there would be any benefit in building a second South Island RNC? Maybe in Dunedin? If the Chch one dies, does Vodafone re-route the traffic to Wellington or something (hypothetical question here)?

No we don't route traffic between them in that regard. But having fewer people logged on to each RNC reduces the risk.

The 3G customers automatically fall back to GPRS until it's restored.

Changing the IuB routing from 1 RNC to another is not a quick change just before christmas we starting migrating 3G cells from manukau RNC to Frankton RNC And this took alot of planning so there was no impact to customers.

As Paul advised devices will pass to the 2G network as long as they are not locked to 3G only

At cell and core network 2G and 3G are seperate so if 3G plays up we can lock down 3G and same for 2G we have full control of the cell. If it has no pwer thats a different story.

So does this mean that Vodafone should arguably keep the 2G network running indefinitely to provide redundancy against an RNC failure?

Arguably yes... LTE sites will probably be configured to offer 3G, GPRS and GSM as well, so there will be no loss of any of the layers, from what I've read.
