Vs. several years ago with BT.

Not counting FTTPoD

Update 12:10pm In response to a few questions we have learnt that some G.fast nodes may be deployed from the fibre cabinets, the advantage being that DC power is available.
This year's pilot will test deployment scenarios and it'll become clearer at that time how Openreach are deploying. I would not be surprised if the 2016/7 financial year deployment is small, as they are still building out for BDUK, and tackling the easier stuff first which means where power and backhaul are easily available.
I read that to mean G.Fast nodes may be deployed from the fibre cabinets not in the fibre cabinets.

Isn't that what they said above? DC power from the fibre cabinets?

It's not like power distribution is a new issue to solve, I'm sure it's a minor technicality.

Not sure we should compare a product whose average delivery price is around the £3000-£5000 mark for install and whose cheapest retail offering is over £200/month with a residential service.

From BT's Chief Network Architect:

Quote:
After our recent trials with early G.FAST equipment we believe that we can run this technology from the cabinet and deliver significant speeds.
They have also gotten DC power from the existing cabinets working fairly recently and will be doing trials accordingly on a few different deployments.

Still, as I said, there are just trials and tons more to do. BT themselves don't know what they're doing yet, hence the pilot.

EDIT: I should mention in conversation with BT staffers that the deployment they are considering is to deliver from very close to the existing FTTC nodes initially and spread out more deeply into the network later on. Coverage will be slow in coming in the beginning.

I imagine that when or if those types of speeds become the norm 10, 20 years down the line that the copyright hounds will go ballistic and really put pressure on governments. 2GB symmetrical is faster than most dedicated servers used by 'pirates' and would no doubt cut into sales as everyone would be able to get 40GB full BD movies in minutes.

Ah yes.

Should be noted, though, that their 305Mb tier is $300 a month. Wonder how much this will be, let alone the installation costs for the 10Gb metro Ethernet kit. Ouch!

Arguably no less fair than comparing a product neither of us can actually get because it's only available to half the country...

US broadband prices are already way higher than ours regardless, they charge $115 for 150Mbps for example.

I know of an area that will be going to 6 upstream frequencies in the very near future. That's 6 individual not aware of how the bonding is going to be just yet, but I imagine it's with one eye on 4x bonding. A few of the nodes need the transmitters changing as they struggle with the 6 carriers.

There are a bunch with 3 or 4 DOCSIS 2.0 carriers already. The problem is that when you go from 2 to 3 or 4 bonded channels you lose 3dB of maximum transmit power. You've doubled the range of the power so it's spread across a wider band.

Any modems that are transmitting at over 51dB right now will max out if they're taken to 3 or 4 bonded channels.

This might be remedied by a feature called extended upstream transmit power which puts the maximum back at 54, however that comes with the price of higher load on the upstream lasers and risks clipping.

As far as I know they're going to try it in a few areas with DFB transmitters and see how it goes. Remaining nodes with F-P transmitters are going to have the transmitters replaced with DFBs if they're field replaceable else the whole thing will have to come out.

Comcast doubles Google Fiber with 2Gbps symmetrical fiber service
Price will be lower than the $400 a month Comcast charges for 505Mbps

[,,]

But while Google and AT&T offer gigabit service for as low as $70 a month, Comcast told Ars it is still evaluating pricing options. Comcast's existing 505Mbps service costs $399.95 a month, making a $70 price point seem unlikely. Comcast told us the 505Mbps customers will be upgraded to Gigabit Pro this year and that the price will be lower than the current $399.95 rate.

Interesting.

See how they feel about running it unlimited when someone's 95th percentile usage on it is 100Mb+ for a month or two ;)

Verizon were rather upset by customers pushing >5TB/month on their service.

Not that surprising as there's very little settlement free peering in the United States, virtually all paid transit.

At my current performance on my above-average VDSL it takes 5 times that.
That's assuming Sony are actually going to allow you to download a line rate, I've seen some pretty horrendous speeds from both PSN and XBL, the last system update I had for the xbox got a lovely 2Mbit/s meaning a 250MB update took over an hour to download and apply.

I think they expect people to leave their consoles in the connected standby modes and have the downloads trickle through in the background :shocked:

Steam downloads used to run at 60Mbps+ on my 70Mbps line most of the time.

Steam is not XBL/PSN unlike both of those Valve seems to be able to do CDN right, the only time I've seen steam download slowly recently is during a sale.
