So I stumbled upon this on reddit, when i first saw it i thought the speeds it was quoting was the speed all the users on a single node had to share but i'm not really sure and i thought i'd come here and ask some of you.

this article refers to cable networks in america.

Vodafone NZ are already working on upgrading their cable network to deliver 200 Mbps performance in order to compete with the fibre UFB.

As the article mentions, the key to higher speeds on HFC is node splitting which is expensive. Retiring legacy DOCSIS 2.0 modems is also needed as they are sitting their taking up bandwidth which can be used more efficiently on the newer protocol.

It's not only retiring older gear, it would also require shutting down their older existing DVB-T TV MUXs and replacing the older STBs - and I can't see that happening with the massive cost cutting occurring at VF.

Even with that you'd need to completely redesign and reengineer the entire network to reduce node sizes to come anywhere close to offering similar contention ratios for higher speeds as what UFB offers.

it's down to cost vs age the older an ISP is the more it's going to cost where as a brand new ISP can do it right off the bat 

just ask Chorus how much is it going to cost to do the upgrade for gigatown

wouldn't they just build the network from scratch to support gigatown? or had they already started building it?

Stick Dunedin into the Chorus mapper, you will find that a big chunk already has 200mbs UFB, so there is plenty to upgrade...

 

 

To be honest I suspect it will be a nice little testbed for the future upgrade of the rest of the UFB network down the line...

Not a whole lot at all.. The UFB architecture has changed progressively each year, with the move from away from cabinets to ABFAT's an so on, and reduction of the splits. Dunedin really is no different to anywhere else.

There had been some talk that the town that won Gigatown would potentially see a trial of 10GPON gear at some point in the future.

Alot of areas currently with cable are going to have fibre within the next couple of years so its probably barely worth it

DVB-T? Do you mean DVB-C

I cant see cable lasting more than 5 years. With VF's customer service policy they don't seem to really want customers anyways.

Telecom managed to survive with really poor service back in the old days. I think you don't realise how tolerant the average kiwi is of poor telecommunications service. Sad but true. :(

I think most of the market is mostly worried about cost (and why not?).

Is there really much you can do with Gigabit speed anyway?

It'd just be good for having good speeds when people are downloading on your connection, you'll still have fast browsing

Any why would browsing be any faster just because it's a Gb connection?

You're never going to saturate a 100Mbps connection now, so any such benefits aren't going to be visible.

How many people are you planning on having downloading from your connection? Hundreds?
