After reading these posts i thought I would throw in my own 2p

The upstream launch with Broadband Size XXL of only 1.5Mb is nothing to do with core capactiy but more to do with the "pre cert" headend gear. The initial trial of upstream channel binding was done with Arris CMTS equipment which is silver cdertified DOCSIS 3 and allows upstream channel bonding. I believe 4.5Mbps upload was tested at this phase by bonding three channels together.

The equipment that has passed standard is the Cisco 10k series uBR chassis, both Docsis and Eurodocsis standards are being trialled currently and wil no doubt be franchise specific upon completion.

The modem that is being supplied will be the rather sexy lookig Ambit VMNG 300 Docsis 3 modem. It is very different to current modems and is a matte polished finish to bring it inline with more modern equipment (think playstation 3).

And as for the initial post comments, the news that Virgin is the fastest doesnt come as a surprise but please bear the following factors in mind...

Virgins total speed is calculated on all three broadband tiers (2mb, 10mb and 20mb). Considering that 2.4million of its customers use 2Mb, thats quite an impressive result to have!
Faster speeds have inherent problems for all networks, how many non PC enthusiasts have high speed broadband from "legacy" cable days and may not have the PC (or modem) to support such a fast speed.
The speed tests dont take how the testers connect to the internet, the avergae wireless user will be "G" based, severley restricting most speed test results.

So overall, speed test sites are rubbish! They will never give you an varying result of your speed! If you want to judge your speed then use a newsgroup server and download large files to judge your true speed.
