Building A Community Wireless Network From Scratch

adelayde writes "This summer I've been involved in a project to build a community-orientated wireless network in the city of Bristol, England. Recently I published an article ( mirrored here and here) describing what we have achieved so far, including some interesting thoughts on passive repeaters. There is a supporting site (mirrored here) with detailed instructions on how to build antennae, and the main project web site is also available here. A bit of own trumpet blowing perhaps, but I think it'll be of interest to those readers involved in similar projects and be of some help to those thinking of starting their own."

      Hi Jonathan,

      Thanks for your comments. Yes, we only have 4 houses connected at the moment, this have proven that it works. If you have a look at the project web site, you'll see that we're making funding applications at the moment in order to install more nodes - it's a question of finance essentially. There are plans in the next month to put up several new nodes and to exetend the back-bone to cover a wider area. It is a coumminity oriented project and so anyone with the wherewithal to do so can put up a node now and get connected. If you are interest in being involved in the project, check out the web site and join the mailing list. BTW. We are and have been in discussion with the city council and are looking for funding there.

    Lots of articles appear on slashdot about ISPs monitoring communications for the government, shutting sites down without authorization or anything resembling due process (important if you are a US citizen!), operating system and software vendors restricting freedoms, abuses of media by government PsyOps (ack!) organizations, media conglomerates manipulating editorials, ad nauseum.

    While all of that may or may not be true, there is now a technology that can greatly reduce the reliance of the technically inclined and general populace alike on these large, controlled networks. This is the first time in history that a viable, high bandwidth technology can be bought into for a hundred bucks and some clever thought. The signifigance of that is not immediately apparent now, but I suspect it will become VERY important in the years to come.

    If you really care about getting shafted by your ISP and care about free speech this is a avenue to pursue in addition to your standard channels of protest. Set up local networks! Once upon a time, we did this with modems, call forwarding lines, and crummy XTs. A bunch of kids trading software provoked national secret service investigations. Not with the internet, but with long distance phone calls. 802.11 is making being a ham radio operator interesting again - I can play with antennas and build networks on the cheap! At 11mbits to boot! When I was in high school, I thought the kenwood handheld and a battery operated packet modem was pretty pimp - and it cost me a lot more than a d-link pcmcia card!

    If you live in a high density area, look at getting together a co-op for bandwidth. Distribute it on WiFi. Get people together and pool some cash. The networks are there, and once they're built, they only have to be connected. There is no reason that in 5 years, there can't be an alternative to commercial ISPs for bandwidth. Just as nobody thought the internet would work (what! no circuits! no central provide!), there is no evidence a widely distributed decentralized wireless network won't, either.

    Security is a non starter. Make the network all-encompassing and encrypt your traffic.

    Combine the technologies with something like Freenet (freenetproject.org), and you have a real motivator for social change (like it or not). Run more static nodes!

      I don't think they'd mind a wireless ISP with a T3, because a T3 still costs quite a bit of money. From the perspective of an ISP, a wireless or wired service looks the same if it has a T3, they don't care what happens beyond the router at the ISP itself. What they would object to is running a "community" ISP off of domestic ADSL lines. No matter what your "good intentions", ADSL is as cheap as it is because of calculations done by the telcos of how many potential paying customers there are per exchange. If suddenly there are far fewer paying customers because everyone's piggybacking on a few who do pay (even if those people do give their service away voluntarily) then the price of ADSL will have to go up by a proportional amount. Imagine what happens if instead of 10 paying ADSL customers an telco gets 1 and 9 sharing it - ADSL will have to become 10x more expensive for those that do pay, and then will they be so willing to give it away for free?

      The technology works - 512k down is a lot of bandwidth for sporadic network loads like web browsing and reading email (less for streaming video and file downloads, sure). Wireless access points are cheap, 802.11b PCMCIA cards are cheap, DHCP and no WEP means that administration costs are trivial. But the economics don't, and so-called community ISPs are going to kill the goose that laid the golden egg, if they're not careful.

    While I think that creating more local nets like we see here is great, it will take much more than a project like this to get rid of the "Oppressive ISPs."
    The community in the article is still getting net access through a DSL modem, so they are still beholden to the Telco powers-that-be. If enough communities were to start up projects like this, and link together using their own methods, then a new form of Internet could take shape independent of the Telcos.
    Imagine a mesh network on a national or international scale created from local nets and linked through purely public lines. Either that, or enough such networks sharing a few high-bandwidth connections along with freenet and tunnelling to make any monitoring and censorship pointless. The ISP's would have to adapt if enough communities simply shared one connection. The one's that refuse to move away from "one person/household == one account" will hopefully wither away.
    As much as the Internet has become a big part of the way we live, we must take a greater part in shaping the way it develops if we want to retain the freedom we have with it, or to gain back the freedom we had before the Internet was declared a different arena from any other global communication tool (See DMCA, COPA, the recent decree from Panama etc for examples of this problem).

    As a cheaper alternative, why provide any direct bandwidth to the Internet? Use spare older boxes and set-up local news, email and web servers -- almost stepping back to UUCP days. It's a little hard for The Man to control your connection when you hardly have one, except for news and email feed. The local community web sites might not be too great, but they'd be in the community, which could be a plus.

    Anyone who wanted could toss spare boxes onto your community intranet. Games servers, web sites, local small business -- And all without worrying about the pipe bill.

  16. WiFi BBS model by AndroidCat · · Score: 5, Interesting
    The current model for WiFi community networks seems to be that of a community wireless pipe to the Internet. Now that sort of project is worthy and has it's place. The problem is cash and the pipe.

    Dropping it on an existing home-use DSL will cause .. trouble. If it doesn't violate the AUP, it will soon, and since the usage curve of a community WAN should be easy to detect.. (Sympatico has imposed a monthly transfer cap with extra charges past the cap.)

    Alternately, a group could pool/raise the money for a legit connection, but then you're talking about money and organization. More power to those with the time for it.

    One obsolete model was that of a lone operator setting up their own system and paying the costs out of pocket: The BBS.

    I ran a BBS (Coherent/Linux based) for a decade until the Internet killed BBSs. (In the end, I tried a web-based BBS, still through my two phone lines. Couldn't afford that and a pipe out to the Internet, it died.) The main kicker was always the phone lines. I could have supported a large number of users even on a 486, but I couldn't justify the cost of the phone lines.

    Now WiFi might make that model viable again. (After all, other than the cost of equipment, it's free.) WiFi doesn't have the coverage of the local telephone, but the number of "lines" are rather large.

    I'm not talking about ye olde text BBS here, of course. Times have changed as have user expectations. I just think there might once again be room for a one-person cheep operation. What it would have to offer to make it attactive to users, I leave as an exercise...

    Being from Bristol (UK), an early wireless adopter and a computing student, this article was very interesting.

    However, I'm going to be very cynical and say that I don't see the point. What you have effectively done is split a product that costs >=£100 per month (2Mb ADSL) between 4 people. Individually it would cost those 4 people £20 each (512k ADSL for £19.99 per month).

    While I think the project is a great excuse for the use of interesting technology, on such a small scale it's ultimately pointless.

    The current aim of the project is feeble: "the aim was to prove that a portion of this connection could be successfully shared between a number of local residents or community groups by using wireless technology". Well, I could have saved you a lot of time and effort and told you it was possible :-)

    To make the project of any use (imho), it either needs to be far more widespread than it is (as you suggest, explore into other parts of Bristol), and approach Bristol City Council directly for funding/support, or there needs to be some benefit for those using it on a small scale, that there otherwise could not be. Simply giving 4 users ~512Kb/sec each isn't much benefit.

    I'm pretty sure this might get moderated as a troll (if moderated at all) but that isn't the intention. Coming from where the article is based, it's hard not to get personal about the details - and although this project has a lot of potential, it seems to be in a very unevolved state.

  20. Mulling over the possibilities by praedor · · Score: 3, Interesting

    I have been mulling over the possibilities of becoming a local ISP in my rural area since getting here 6 months ago. Where I am there is no cable, no DSL of any kind, and there wont be for the foreseeable future. What IS available is satellite internet...high latency and HIGH cost. I (and my neighbors who haven't gone stupid and overpaid for satellite) am stuck with pathetic dialup with rarely better than 36kbps speeds.


    As a result, I have been considering the local ISP possibilities. It would not be free, as a connection costs, plain and simple. I would also have to maintain the servers and handhold people in setting up and trouble shooting, thus I would charge - but I would like to charge below what telcos and cable companies charge for broadband access. I would even like to undercut AOL, which I suspect at least some locals would likely currently use. Basically, I would like to charge enough to cover the costs of a T1 line (or halfline) plus a little extra for equipment costs. I see something in the line of $17/mo.


    This is based on a few assumptions: at least 100 local area families/individuals/companies interested in the service and the ability to gain wireless coverage over the important areas. This is the hitch. I am in flat country (Indiana) with trees hither and yon. There is a half-mile between me and my next-door neighbor. The local town is, of course, more tightly packed BUT there are trees everywhere. I can see my neighbor's house and even the house beyond him. The town is another 500 meters further still and hidden amongst trees.


    I have checked on various community wireless network projects now and again and almost every one of them is associated with cities (clear LOS from rooftop to rooftop) and few tall trees. Other rural networks are associated treeless expanses. Are there any such networks being worked in rural settings that actually includes trees? Not a tree here and there, but TREES? If so, how do you obtain interconnectivity via wireless? I suppose with enough nodes useful signals could be passed through treed areas by "force" but I would like to be as clean an efficient (and cost effective) as possible if I decide to go into this further.
