Loftus:
Currently they are limited to the 14MB HSPA+.

All of Telecom's XT sites support HSPA+ which enables downloading at up to 21 Mbps.

Of course to get close to that speed you need to be the only active user in the cell and be located in pretty good coverage conditions.

In theory if Telecom deployed Dual-Cell that speed could be increased to 42 Mbps - now we're talking!

There are many sites that don't have hspa+ on Telecom.

Telecom said that the HSPA+ upgrade was 'complete' eariler this year, however many areas were only upgraded over the past few months with still quite a bit to go.

Really all of them?

Source is here (TNZ FAQ) The relevant quote is: "The XT network has been turbo charged with a technology called HSPA+"

Ask an Engineer on the TCNZ mobile network and see what they say

I might be wrong

sbiddle: I'm really surprised this hasn't received more publicity.

sbiddle: Telecom need the spectrum to be able to deploy upgrades such as dual carriers on the XT network.

Sorry for sounding like a very un-geekish geek.... But what is the dual carriers thing?

... Thanks

To summarise dual carriers briefly: it's a case of essentially having two cellsites that transmit from a single site which in turn doubles the capacity of a site. Devices that support dual carriers with MIMO antennas can connect to both carriers and double the speeds that are available from a regular single carrier network.

I thought Dual Carriers and MIMO are two separate things? If you combine both I think you can get greater speeds than DC by itself (42Mbps)?

You do not need MIMO for 42mbps DL yes they are very different
