Just received

Telecom Retail Chief Executive Chris Quin announced today that Telecom will begin rolling out dual-carrier HSDPA to New Zealanders by Christmas, extending coverage to half the population during 2013.

"Telecom is committed to maintaining its Smartphone Network advantage and with more dual-carrier capable devices hitting the market, we believe investing in this technology and deploying it rapidly will make a real difference for our customers.

"This comes on top of the already substantial investment Telecom has made in our Smartphone Network, which was built with smart phones in mind and covers 97% of the population with super-fast 3G coverage.

"We've begun by trialling dual-carrier technology with our Telecom people in Auckland, which - with 2,500 people - is a bit like trialling it in a small town."

Do many handsets on the market support this? If not, wouldn't they be better off putting the work into their LTE network?

New iDevices support it (iPad 3 & iPhone 5) as does the SIII and a few others from memory.. but I could be wrong.

No DC-HSPA on the Galaxy SIII

iPhone 5 is the only handset on sale in the NZ market with DC capability.

...or they've had a knee-jerk since 2deg said it also had dual carrier sites so VF should cease with the greyhound.
And like you say it'll by them more time.

What LTE rollout? They are launching a trial, nothing more. Don't be sucked in my slick marketing!

Vodafone are miles ahead with their LTE rollout and have a far better technical solution but are obviously going to announce this when it's live and ready to carry traffic rather than making premature announcements.

Handsets don't need to support it. The added advantage is it also increases overall capacity of the cell.

Yip this is the main purpose of DC - it's not just about data speeds, it's the fact you're doubling the capacity of the network off the particular cellsite. Vodafone have tri carrier sites out there and also deployed quad carrier sites during the World Cup, simply to increase capacity.

FYI 3rd carrier is not bonded

Telecom probably don't need LTE any time soon. They have plenty of 850 & 2100 MHz spectrum and the latest standards allow bonding of carriers across different bands so there is plenty of life left in WCDMA before they need to go to LTE. Not sure if many devices support more than dual carrier at the moment though.

I get better speeds on Telstra DC-HSPA+ than I've seen on the Telstra LTE network (on 3rd gen iPad)

Perhaps this thread could benefit from some facts.

Especially the fact that Dual Carrier (DC) enables a device to use the power and bandwidth of two radio bearers (carriers) on the same cell site to transport Data. This can, in ideal radio conditions, double the available bandwidth for the device.

The capacity of a cell site does not increase other than, when available, devices using DC will get on and off the network quicker freeing up the cell power for other users. This means that if there are no DC devices using the network then there is no change to the cell performance, capacity or availability.

Dual Carrier requires two side by side blocks of spectrum (carriers) within the same 3G frequency band to operate. The 3G bands in use in NZ are 850MHz (Telecom), 900MHz (Voda), and 2100MHz (Telecom, Voda & 2D).

The comments I write on this forum do not necessarily reflect the views of my employer and as such cannot be taken as official statements of my employer.

So the big "LTE 4G" on the front of their web page means nothing?

Whose web page? Neither Vodafone's home page nor Telecom's mentions LTE...
