Community Broadband and BDUK-can it work? 03/06/2011
With the recent announcement by BDUK (Broadband Delivery UK) that the first tranche of the £830 million promised for delivering super-fast broadband, things now start to get interesting. £50 million is up for grabs and the Government has basically said it’s up to local communities, through their local authorities, to come up with ideas and apply for the money. Whether using local authorities is the best vehicle, we’ll see (I though the idea was to give power to the people and cut through the local bureaucracy) but they had to start somewhere. Personally, I would have thought using the local community councils would have been better. The irony is this-those big councils/authorities will already have access to superfast broadband (lets aim high here and say anything greater than 20Mb/secs is superfast) so it’s the outlying areas, the more rural sort of places we are talking about. Basically where the likes of BT and Virgin either never built or don’t see as immediately profitable. Which in turn will be more technically challenged. You only need to look at the 4 BDUK pilot sites to see that. Which leads me to those technical challenges. You either go one of two ways-wired or wireless. Wired (cable, fibre optic, copper) is the more long term and feasible way to go because it’s a lot more future proof). Wireless (Wi-Fi) is cheap and relatively easy to install. Wireless also includes the mobile operators but you only need to look at the recent debacle in London with O2 and Iphone users, to see that those chaps are now looking at Wi-Fi to offload the data costs of upgrading their cell systems. The system can’t cope with the amount of bandwidth that hungry smartphones desire. However, wired has an awful lot of up front costs in laying the cable (even if BT go down the fibre to the home route).Wireless is limited (although the review of the 800Mhz spectrum could go a long way to improving things) as it’s an unregulated spectrum, it’s very crowded and has limited distance capabilities). So what do these local communities do? It all depends on their aspirations. Local people need to decide what they want to do before embarking on this brave new world. The Government defines superfast broadband as > 2Mb/secs. Which is pitiful when you consider that none of the big players now market such a service. Indeed, Virgin dropped it some 2 years ago! If your looking for that sort of speed, I would suggest wireless is the way to go. Anything higher, the limitations of the physics of radio, shared amongst many, start to come in to play and you need to go wired. But wired means ducts, or digging up roads, street cabinets, commercial power, battery backup, local road laws, wayleave-the list goes on and on. Even if you manage to get access to BT ducts, it still will be a long slog. If it was that easy, we would have done it years ago. There is also a perverse irony in the wired/wireless argument-most people in the home use a wireless network but it is brought to them via a wired connection. If you are out of the main broadband areas, the differences in speed between a wireless connection from a street light, or in your home router, start to shrink. But I digress. Ofcom also worry, or should, that in the gold rush for superfast broadband, they end up with a UK that has lots of different technologies and solutions ton what is a common problem. For me, it’s not the local solution that will be the roadblock-it’s the backhaul. That is, use whatever means to connect communities (I’m trying to get a small wireless network up and running in my area-more out of interest than anything else) but where does the fat pipe come from? Wired will involve the BT route above which, in 99.9% of cases, doesn’t bare thinking about and will be beyond the capabilities of most (though not all), so wireless seems appropriate. My town has about 7,000 people-with about 12 strategically placed mesh transmitters/receivers, with dynamic routing, and I could blanket the town. I don’t think it would be hard to find 12 people who would let me put an aerial on the roof and access to a power socket in the loft. Indeed, with the local authority help, there are enough of their buildings where this could be the case. We have a lot of people in outlying areas (farmers and rich people J ) where wireless would be ideal, through P2P (point to point radios), and most probably increase their broadband speeds. Again, ironically, it’s probably those who need it the most. That backhaul would need to be a minimum 1Gb/sec, upgradeable, to satisfy the needs of local people. The counter argument is if all your aiming for is 2Mb/secs, then you don’t need this but it really is a pitiful speed-one stream of BBi Player and your maxed out. This is the part that needs an answer, not the local bit. So far, I’ve not seen this. People are concentrating on how to connect people-that is easy, with wireless. Unfortunately, this is where you need a big player, with wired connections. Which usually means BT, and/or a service partner/provider. It also costs a fortune. Which means we are back to the beginning again. It will be interesting to see how this all pans out, and what/where/how the money can be spent on. I hope that BDUK will help in this part as the local part is the easy bit. Add Comment If you've been following the news websites recently, you'll know there has been a breaking story detailing a breach on the corporate website of ACS:LAW ACS:Law are a company who chase people, on behalf of the movie and record industry, who download content that they shouldn't be-in laymans terms, movies and music. Usually from illegal sources and distributed by Torrent sites and other P2P programs (Limewire is an example). **Update**-I had to link to the wiki article as the ACS:Law website is down-I wonder why? The main thrust of the story is that a hacker group managed to get inside the servers of said company and obtain files detailing not only IP address's (the "fingerprint" of your broadband connection) but the customer details of who owns that connection. This group, being the charitable souls that they are, then put these files up on the web for anybody to download and view-ironically on the same Torrent systems that were used by the people fingered in the ACS:LAW files. They are still there-go to any Torrent site (here's one I am reliably informed that will point you in the right direction-I wouldn't know being an honest chap). You'll need a Torrent client to download the files-again, so I'm told.I still think Netscape is groundbreaking technology in action :-) Just to rub salt on the wounds the UK's Information Commissioner has said the company may face a fine of up to £500,000 for this breach of the Data Protection Act. The irony increase as this has happened in the same week that the ICO have issued guidelines for small and medium business's to protect this sort of data-ouch! Now, I've not seen these files as I keep away from torrents and all that but I'm reliably informed (I'm well informed me) that there are customer details, postcodes etc for each infringement of copyright. So if you download the files, you can look at the various peeps and see if your neighbour is one of the "bad people". Again, if I was betting man and reading the various articles on the web, I bet the files being downloaded, especially the movie ones, are not the type you would show your mother-more likely there's a mother in them-all the above is alledged of course. So what's this got to do with wireless you say? What's you point matey? My point is, if you know about the likes of ACS:Law and what they do, and you still want to get these files, would you be likely to do it on your own broadband connection? Nope. You'd use someone else's (an open/unsecured wireless one) or you'd hack into a weakly configured wireless network (again, using the likes of aircrack facilitates this-so I'm told). This is probably the most high profile news story to date I can think of that demonstrates why you need to have a very high level of wireless security on your home broadband network. So if you don't want a letter demanding £££'s for a copy of Debbie Does Dagenham because your wireless broadband connection is open to the world and his porn hound, drop us a line or look at some of the tutorials. Happy downloading ;-) First of all apoligies-I've not found the time to keep the blog up to date. It's a mixture of work and laziness :-) I've been meaning to write about this for a while-BT FON. What's that then I hear you cry-and if your a BT customer, then that wouldn't surprise me! BT FON is a freebie that BT throw into your home broadband wi-fi connection. Essentially if you give a bit up of your wi-fi connection for public consumption, you can then use other BT FON users bandwidth when your out and about-sounds great. A massive source of untapped broadband supply, just waiting for you, the loyal BT user, to use. One problem-most users dont know they have signed up for this service.On all new users, the facilty is opt-in by default-that is, BT have it turned on on your router when it is shipped to you/ bought by you. Which is fine if you get your 8Mb/secs (lucky you) but not so if your getting a few Megs. I'm surprised more has not been made of this when you consider the Facebook row over privacy settings story.You would think a big company basically making decisons on what some people see as important as their gas, electricity and water-giving it away from free-would have eliicted some sort of response but no. I think a lot of just amplifies the general ambiliance and ignorance most broadband users have towards that home connection.Think of it this way-its like the Water company saying if you give up some water from your garden hose connection, you can use someone else's when your out. Thing is: 1) I doubt if you would sign up for it 2) you wont use it very often 3) the reason for 1 is 2 But they've stuck a big map up on the Web where all those free taps are-dont believe me? Try this and stick in your postcode-ok, here's one I did earlier The large blue circles represent areas where the indivdual wi-fi hotspots are so many, BT need to show this as one big circle.Now I'm sorry, I know that the British are known for their generosity but I simple dont believe that all those people are 1) giving up their bandwidth and 2) are doing it of their own free will. Come on-the Brits are so paranoid do you think they are going to let their neighbours onto their wi-fi? No chance. Not a Scooby Doo in hell's chance. But I mentioned exploit in the header-now, the way BT FON works is it takes the "pie" that is your broadband connection and slices it up-with you keeping about 90% (based on a 8Mb/secs connection-lol) and the other 10% goes to Joe Bloggs looking for porn or some torrents under the radar, parked outside or next door. It is secure (WPA/WPA2), but secure comes with a caveat-WPA will be broken in the next few years, its only matter of time. As discussed in a previous post, there are now cloud services willing to do the job for you of finding that elusive password.Anyway I digress.Somebody will find a hole in this system and crack it wide open-if its not been been done already and the blackhats are just keeping Mum about it. And yes, you do need to sign in with your BT FON username and password-you know, that same one you ask your Mum and Dad for when you want to get your email...... The biggest shame about this is that in these day where we talk about the broadband poor, that BT havent worked out a way to build a super mesh network for the whole country-think about it-thousands,millions of wi-fi access points being combined together for the greater and common good.Now that's a good idea. WPA protection dead in the water (cloud) 01/05/2010
Looks like WPA as a step up from WEP for protecting your wireless home network will soon be dead in the water. Cloud computing is now being offered (for a small fee) by not one, but two, operators. This technology offers to take a WPA capture file (which can easily be obtained by the likes of Aircrack) and combined with your SSID (the advertisement that you see when you fire up your laptop). The clever thing is that it takes this SSID and tailors the "attack" on the password. Unlike WEP, the attack is still brute force in nature, in that it uses a dictionary attack. Granted, the dictionary is an eye-watering 540 million long list of words, so if your password is long enough and random enough, then your safe. Unfortunately, most people don't use long and random passwords-duh. Its only a matter of time before others get in on this market and/or someone gives it away for free. WPA2 is an option but either people wont/dont know about this option or their hardware wont support it. Or cant be bothered to change it. Time to look out that cabling tool. Speed test sites 09/07/2009
Just a quickie today-I have a particular soft spot (quicksand) for speed test sites. But I’ve found this one which seems to tick all the boxes. You can do the usual HTTP tests and if you sign up, you get to record your history. But it also has the option to do direct downloads, by HTTP or FTP which when combined with a good free download meter really gives you an idea of the speeds your are getting. If you have a 20Mb connection (or higher-lucky you!), then I would go for the direct downloads and download at least 2 files at the same time in order to “fill up” your connection.I find only one connection at one time, even on the fastest servers, can lead to not maxing out your available bandwidth thereby giving misleading results It seems to be mainly ADSL based but it works on your cable modem connection as well. The servers are based in Slough so latency and bandwidth should not be an issue. Tracerouting from my home connection (middle of the UK) shows a 12 hop route with a round trip time of 22ms-which is blooming good!
