BT Unveils 1000Mbps Capable G.fast Broadband Rollout For the United Kingdom 132

Mark.JUK writes The national telecoms operator for the United Kingdom, BT, has today announced that it will begin a country-wide deployment of the next generation hybrid-fibre G.fast (ITU G.9701) broadband technology from 2016/17, with most homes being told to expect speeds of up to 500Mbps (Megabits per second) and a premium service offering 1000Mbps will also be available.

At present BT already covers most of the UK with hybrid Fibre-to-the-Cabinet (FTTC) technology, which delivers download speeds of up to 80Mbps by running a fibre optic cable to a local street cabinet and then using VDSL2 over the remaining copper line from the cabinet to homes. G.fast follows a similar principal, but it brings the fibre optic cable even closer to homes (often by installing smaller remote nodes on telegraph poles) and uses more radio spectrum (17-106MHz) over a shorter remaining run of copper cable (ideally less than 250 metres). The reliance upon copper cable means that the real-world speeds for some, such as those living furthest away from the remote nodes, will probably struggle to match up to BT's claims. Nevertheless many telecoms operators see this as being a more cost effective approach to broadband than deploying a pure fibre optic / Fibre-to-the-Home (FTTH) network.

    My local telephone exchange has been enabled for fibre-to-the-cabinet (FTTC) for a year and a half

    The street cabinet my line connects to has not been upgraded. I can't even physically find the damn thing, no idea where they've hidden it. Maybe BT doesn't either. Nobody can tell me when or if it will be enabled.

    I can get 4G LTE on my phone and get 30 Mbit/sec up or down. But ADSL2 is as fast as I can get - with the distance from my exchange to my house, I get no more than 9 Mbit/sec down (but more often than not closer to 6 Mbit/sec) and no more than 1 Mbit/sec up.

    I'm all in favour of gigabit broadband rollouts - but I want them to finish the FTTC programme first.

    Also - I live in the middle of a city of 230,000 people, and the area I'm in is entirely residential. They'd get more fibre subscribers if they enabled more cabinets.

      This seems to be a common problem. It was nearly three years from when they upgraded our exchange to when they did the cabinets. For the interim period you're in the weird position where querying the rollout information tells you that your exchange is in a state of "AO" (Accepting Orders), but if you try to order it you're told you can't have it. You can't get any projected date when it will be available, because if you go to the "When will FTTC be available?" pages you're told your exchange is already e

          You're using an argument technique known as "putting up a straw man". We're discussing the tendency of BT to upgrade exchanges long before they do the corresponding cabinets (which they do), so you raise an imagined case of one person behaving unreasonably because, although his local cabinets have been upgraded, he can't get service.

It hadn't been connected to anything inside the house for a very long time - telephone service came in on the other side of the house, underground. They just never got around to removing the poles and the above-ground wires that didn't have a signal going through them.

        It might be true to say that new developments don't now have telegraph poles, but the vast majority of the UK still does.

In both houses, the wire eventually fell off the back. I presume that the previous owners did notice when they re-did their telephone wiring...

I've done quite a few trace routes on different ISPs during file transfers, and in my experience over half of the time that I got below line rate transfers was because a trace route showed latency and jitter on a peering link with the ISP, not an issue with the remote server.

A quick internet search will confirm this as there are a number of posts on the topic from about 10 years ago.

        There is no excuse for having congestion in your network on a daily or weekly. It can happen once in a blue moon when a line becomes unexpectedly busy, but it should never be the normal mode of operations.

    Slashdot are posting what The Register posted two days ago, so I'll post the same comment I posted there two days ago:

    I work for a UK school.

    BT took nearly TWO YEARS to get a leased line to us. They were blocked from completion after we cancelled the contract because they said there was a 20th delay because "there's not enough room in the duct" followed by "there's not enough room at the exchange". You'd have thought someone might notice in two years that you had no room, eh?

    We cancelled because, despite wonderful promises, prices and speeds, we never actually managed to get the line into the building.

    In the meantime, I'm running a school for 400 kids on a VDSL line with ADSL backup which BT promise me can get "45Mbps" and "20Mbps" at best, respectively. Funny. Because my Smoothwall says we've never pushed more than 10Mbps for a fraction of a second and the average over the working day - with 500 users and 600 devices - is somewhere around 4MBps down and 1MBps up..

    BT can make all the "maximum" speed promises they want. If you can't get it installed, or the actual download is so much less than the maximum, it's pointless. Absolutely pointless.

    Ironically, I get 32Mbps download on 4G when sitting in the IT Office. If only 4G didn't have such pathetic data allowances.

    can I have a unicorn, please? Local exchange has been 'enabled' since June 2013, but I don't know anyone who can actually get Infinity in my town. I live a mile from the exchange, and 100 yards from the cabinet, and am still on standard broadband.

    The story keeps changing, too, whenever I talk to BT. First it was that the cabinet hadn't been upgraded, then that it couldn't be upgraded, and now it's because fuck you, that's why. Their website says they cover two-thirds of the UK (which is a weird definition of 'most', but I suppose it is greater than 50%), but it also says (in paraphrase) that if you live more than 300 feet from an exchange, forget it. Lots of the UK, and especially Scotland, is still pretty rural, so I don't expect to see anything better than broadband any time this decade.

    So while I'd welcome the service they claim to be offering, the fact that they haven't managed to deliver the original service to about 40% of the UK yet, does make me wonder if it'll ever actually materialise.

And even then they barely get 20 MBits downlink and a really horrid uplink. Comcast is twice as fast at a minimum.

      I wonder just how many fibers they ran to the pole in the first place. With the tech they're using, you only need one fiber or fiber pair to the node, then the node uplinks to the fiber. With modern fiber networks, each customer gets their own separate strand of fiber. They may need to re-run the fiber or use a sub-optimal fiber design of having a fiber node. Modern fiber networks have no nodes. Fiber strait back to the trunk.
  • Up to 1000 Mbps - yeah, perhaps if you have built your house right on top of the cabinet. In fact, not even then.

    I was on their FTTC product for a couple of years, the one that's "up to" 80 Mbps. I got 18 down and 0.75 up. I tried reporting the speed to them on several occasions, especially the upstream speed which was very limiting, only to be told they didn't consider that to be a problem - it's within the range of speeds considered acceptable for that product.

    • Change ISP. Seriously.

      The "big 6" will shag you about. If you move to AAISP or Zen or phone.coop (there are a lot more), they have a vested interested in keeping you happy and will keep tickets open until openbletch fix it.

       

  • TFA says it "uses more radio spectrum". I am confused. Does that means they use some radio network like WiFi or WiMax?
    • DSL services use a series of narrow bandwidth carriers across the spectrum. VDSL2 ranges from 100kHz 33MHz down the wire. G.fast adds more high frequencies.

      The reality is that higher frequencies are more susceptable to crosstalk, have higher attentuation and are extremely touchy about bridge taps, bad joints, etc.

      Whilst it's entirely _possible_ to run G.Fast on existing copper the question is whether it's _practical_ and the smart money is on it being a failure in service.

    It's highly likely that it will be around 50 metres once crosstalk and other interference is taken into account (VDSL2 operational distances are shown to be suffering badly as more VDSL is rolled out, especially along the rotting distribution infrastructure that BT operates (there has been insufficient infrastructure reinvestment to maintain services since the mid 1980s)
