UK Completes 250km of Undersea Broadband Rollouts

DW100 writes The UK has completed a highly challenging rollout of broadband to remote islands in Scotland, covering 250km of seabed. The work has taken many months but will mean some 150,000 residents in the islands will be able to get broadband of up to 80Mbps. A cable laying ship, the Rene Descartes, carried out the work, with the longest cable stretching 50 miles between islands.

...and let's not start on mixing scales here... km to miles? Do I have to do EVERYTHING? Divide by 1.609.

These are the Scottish islands we're talking about; where the weather can get so bad that even radio stays indoors.

I hear that they are going top relay it to the more remote residents via bagpipes. The whole thing will use Scotland's major sustainable energy source, the virtually limitless supply of hot air from Alex Salmond

[Richard_at_work]

You know what also happens a heck of a lot up there? Storms. And you know what storms can do? Degrade radio transmissions significantly.

And why would submarines be colliding with cables laid on the sea bed? That would require submarines to be dragging themselves across the sea bed - which they don't normally do...

Also, it's much easier to drive all traffic through a few cables where they can be easily tapped by GCHQ.

Wat?

Cable-based communication is potentially much faster than any radio based communication. Each signal pair in a cable can carry as much information that you can transfer over radio.

Depends on what you mean by fast. The speed of light through air is quite a bit faster than through optical fiber or copper, thus yielding lower latency over distances. It's such a difference that the path from New York City to Chicago is now traversed by microwave/laser towers for financial institutions, in order to save a few milliseconds on the round trip and thus yield faster (read: more profitable) trades between the commodities market hub (in Chicago) and the

Re:

New expensive hallow fiber is about 99.5%c, while regular fiber is about 65%c. I'll be happy with regular fiber for now, but once I get 1gb Internet on the cheap, the next upgrade will be hallow fiber trunks for low latency gaming. Regular fiber for the last mile will be fine.

Hallow fiber is what you'll have when the Vatican gets into the ISP business.

Re:

Yeah, but what securities trader worth their salt is going to be on a Scottish island more than 50 miles from anywhere instead of in London?

Re: cable?? Bit extravagant, aren't we?

[garyok]

Wouldn't you need a 500m tall tower for LoS comms with an island 80km away? Good luck keeping that standing in an Atlantic gale.

Re:

[garyok]

Or 125m towers on each side. That's a bit more doable. But... then there's a chance an Islander will climb Satan's ladder and glimpse the beguiling lights of civilisation. Won't end well.

Re:

[Anonymous Coward]

There's no cable at Scapa Flow for this rollout. If you're worried about submarines, I'd be concerned about the cables around Arran and Bute, that's on the way to the submarine base at Faslane. Not that submarines tend to drag themselves along the bottom often enough to worry about the cables.

Re:

[Shinobi]

Radio is slow compared to fibre, it's prone to disruptions from weather and EMI, and, it's actually quite expensive too, in a situation like this.

Re:

[morgauxo]

Umm, no.

The faster the connection the more bandwidth is needed. I suppose that technically there is more bandwidth available in all of the radio spectrum than you are likely to get through one cable. However.. radio has to be shared with every other radio user out there in the world. You don't get to use ALL of the available bandwidth available in the open air for just one thing. You pay some government regulator a ton of money and then you get a channel, a little slice of that bandwidth which you can us

Re:

[unixisc]

So in UK, do mobile carriers like Vodafone offer unlimited data plans? Or conversely, do none of the broadband providers there provide unlimited data plans? This is only extravagant if people in Orkney & Shetland were getting uncapped data from the carriers. Is that the case here?

Re:

[ihtoit]

Hutchison 3G ("Three UK") offer unlimited data on their pay as you go and basic voice contract packages.

Re:

[Computershack]

Radio is no use. You'd need to be on VHF at least in order to get the bandwidth for the speed and VHF and higher is line of sight. You'd need fooking tall towers at either end to overcome the curvature of the earth for that kind of distance between the UK and the islands. Not only that, it can be easily interrupted by both man made and naturally occurring sources.

Re:cable?? Bit extravagant, aren't we?

[lars_stefan_axelsson]

There's this thing called RADIO, invented by a rather clever chap called MARCONI. It allows untethered communication between two points. It doesn't, therefore, rely on cables. It's also potentially much faster than any cable-based system and not prone to submarines colliding with it. Which happens a LOT up Scapa way.

Uhh. While it is true that radio has an edge when it comes to propagation delay compared to fibre, it's not enough to bother any but the staunchest algorithmic trader. When it comes to bandwidth it's not even close, the fibre wins by so much it's not even funny, and that's comparing to microwave, i.e. line of sight radio links, which are difficult to span large stretches of water with, being line of sight. Also since sea water is conductive you have a dickens of a time to deal with all the reflections and other potential signal degradation.

If you want to communicate via radio and it's not line of sight, then the only viable option if you're going to have any kind of bandwidth is satellite. That's both slower and suffers from a much longer delay. Any other radio is going to be much lower frequency (to follow the earth's curvature), and hence severely bandwidth limited.

P.S. Submarines will not cut cables laying on the bottom of the ocean if that's not specifically in their orders to do so. They a) don't spend much time dragging along the ocean floor, and b) have much better charts than you and I (since they also cover military cables and installations) so, that's be the very least of your worries.

Sounds like those sub captains need more training... The sub should never touch the floor.

Better than the USA

[Roodvlees]

So now even remote scottish islanders have better internet than most of the US.
When will the US realize they have to regulate their internet market?
Will it be when Africa passes them in average internet connection?(every other populated continent has)
Will it be when other nations start to apply diplomatic pressure because they are slowing down the world as a whole?
Will it be when they end up as the nation in the world with the worst internet connection?

Re: Better than the USA

[Anonymous Coward]

I live 1km from a small town, about 40km from the nearest major populace. We pay £5 and month (about 8USD) for our broadband. It's about 16MBs and unlimited bandwidth and comes through the copper phone lines. The reason it's so cheap that even though it's a small town, there's at least 8 companies offering broadband so they have to compete. The problem with the U.S. is no competition.

Re:

[unixisc]

How is the US a country w/ the worst internet connection? At least the major cable guys offer unlimited data a month, and price you according to the speed that you wanna rent. Which sounds fair. One has to pay far more than that in other countries - not sure about Europe, but definitely it's far cheaper than Asia

Re:Better than the USA

[OzPeter]

NYC has a higher population density that Tokyo, but Tokyo has connection speeds that NY'ers only dream about.

While you can argue that out in the boondocks high speed internet is harder to do, what is happening in markets like NYC makes the US look like a joke in comparison with other countries with cities of a similar density.

Re:

[unixisc]

Ain't that a given - as there are more consumers, the connections speeds would reduce due to the bandwidth being distributed b/w more people

Re:

[don.g]

I'm having trouble working out if you're being sarcastic or genuinely uninformed.

Re:

[Bengie]

A single $100/port fiber chassis has more bandwidth than all of the USA could use right now during peak hours, and that's divided among only 2500 users. Unless you're proposing 2500 home users need more than 4tb/s of bandwidth. For reference, Netflix is about 30% of peak USA traffic and is about 1tb/s.

Bandwidth density is not an issue unless you're using archaic copper.

[xaxa]

While you can argue that out in the boondocks high speed internet is harder to do, what is happening in markets like NYC makes the US look like a joke in comparison with other countries with cities of a similar density.

The population density of the Outer Hebrides is 9/km^2, about the same as the Scottish Highlands. The Inner Hebrides have 4-5/km^2. I'm pretty sure that will be the least densely populated place in the whole UK.

(However, I live in an out-of-the-way bit of London, and get about 2Mbit/s. That's very unusual though, so unusual that I didn't think to check before renting there.)

Re:

[Trepidity]

That's on its way out. Comcast recently started rolling out data caps [comcast.com] in several major markets, and plans to expand them nationwide over the next five years. Time Warner will probably match them soon.

Re:

[unixisc]

In that case, it would be accurate to say that the US will become worse than others. That's assuming that others have the things people in the US take for granted - like a 15Mbps with unlimited data for just $50/month (which is what I have w/ TWC)

Re:

[dave420]

You can just look at the statistics. The US doesn't fare well in pretty much any class. Substandard service, exorbitant prices, poor coverage, and so on.

Re:

[unixisc]

Something more than platitudes would be more appreciated. Like I get cable internet from TWC with a very good service, reasonably priced, and previously in CA, had the same experience w/ Comcast. If you think the prices are exorbitant, who are you comparing it with? Countries like Estonia & Finland, which have a far lower population density, or countries like China, Korea, Japan & India?

Re:

They're hardly platitudes [newamerica.net], and have been discussed to death. Feigning ignorance isn't really helping your position.

I pay the equivalent of $50 a month for 80mbps down, 20mbps up with no data caps or throttling here in the UK.

Re: Better than the USA

[garyok]

Me too. Although it's not all roses. Page loads do seem to have gotten quite a bit slower since the ISP filters went in. And I'm fairly sure they've started banning sites before they get court orders. Other traffic seems unaffected though.

Re:

[ThinkingGuy]

When will the US realize they have to regulate their internet market?

If the local government only allows one monopoly ISP in a given town, it's not really a "market," is it?

Re:

[Roodvlees]

So the problem is over regulation or just bad regulation? Maybe because it where big companies who brought this regulation into existence in the first place.

Re:

But it is regulated. Just not in the way it should be.

The Brits are confused about units. They can't decide whether to use SI, Imperial, or Ancient Hebrew measurements. Just be thankful they didn't measure the distance in palms or spans.

Agree, submitter is inconsistent with units, mixing them in the same sentence is pretty lax. As for confused, I'm not so sure. In everyday life we seem to be able to mix and match units fairly easily, weight is stones and pounds by default, height is in feet and inches, yet somehow I know my metric measures too. None of it really matters as long as we consistantly use metric for science and engineering.

It's probably because it's a French company doing a rollout in British territory. The French sources will quote km, the British will quote miles.

Undersea broadband?

I guess this undersea broadband deployment means that a certain sea sponge who lives in a pineapple under the sea can finally get broadband!

I wonder if this means that the Krusty Krab will start offering free Wi-Fi?
