DIY: Building A Wireless Freenet

techmuse writes: "Moshe Bar has an excellent article at Byte describing how he designed a wireless freenet for his community, and convinced his neighbors to participate. Most importantly, the freenet has resulted in new forms of interaction and strengthened social ties within his own local community (the inverse of what happens on the wider Internet)." And since consumer-grade wireless access points are now cheaper than a large hard drive, this sort of guide is especially welcome.

    Where are you buying them that cheap? I just bought a 40 GB for $100, I have yet to see an access point anywhere near that.

    I have long wondered why we don't have neighborhood-supported Internet access. Where I live, though, a new subdivision was coming up where people would have the funds to pay for this type of technology. It was not a bad deal:
    • Unlimited (virtually) email addresses
    • Unlimited (virtually) web space
    • Private, backed up file areas
    • T-1 Internet connection
    • NAT technology, no proxy


    The problem was with everyone not wanting to pay. It would have been T-1 access to every home for about 70 dollars per month. Every home built out there would have a 24 port hub and CAT 5 wiring as part of the house.


    I have also wondered why this has not caught on, considering hotels and dorm rooms at schools have this technology implemented just fine.

  3. Why can't this be applied to mobile devices? by mini+me · · Score: 4, Interesting

    I always thought one way to roll out the mobile internet is to create a freenet like network between all the mobile nodes. Every device acts as a node for the network and can route data to nearby nodes.

    For argument sake, lets say that each device can transmit up to 100ft. You however want to connect to a node that is 200ft. away. Luckly there is a node in between you that can route the information between you. Lets say you want to connect to someone miles away, well the same rules apply, just keep hoping until you find the host. Certain internet access points would be established too to keep wireless trafic to a minimum (for less hops) as well as routing traffic to nodes outside of your range.

    This would take some pretty fancy routing but I think it would be possible. If these nodes were added to every device that can use them (cell phones, pdas, radios, etc) then the network will quickly form. It may not be as ideal as other wireless network topolgies, but it is better than nothing at all, like we have right now!

    Wow, this is a great idea. But the application I'd really like to see is a T3 (or better) being pretty much standard coming into eavery big apartment building, or city block. Using wireless could save so much on infrastructure costs that it wouldn't be unreasonable to expect high-speed internet to be cheap and accessible almost universally. Between this and sub-$700 PCs, we could have most of the population online very soon... and maybe an ubiquity of online communication would make everyone's life better.

    Or maybe I'm just a geek.

    This is exactly what we want to see -- hobbyists helping hobbyists. It might not make money, but it's a valuable contribution to the community, both real-world and virtual.

    I assume that conducting the Freenet experiment with less-versed people might not be feasible altogether. At least not with today's technology.

    True, not everyone has the expertise available to set up several servers/firewalls/NAT boxes, and this could well be the major challenge facing Open Source. Someone should put together a wireless_net.rpm 'For Idiots' or similar, then finally things will start to change.

    Local networks are probably going to be the wave of the future as costs decrease and several-PC homes start to become more common. Experiments like this, pushing forward the mass application of such technology, should be happening everywhere.

The internet has disappointed me in locating like minded people in my area, but I've always believed the Internet can be a wonderful way of connecting to others. It's a shame all the hype about pr0n, hackers, and AOL idiot's make us forget the cool folks we speak to in email and via IM.

      Going back to those BBS days via a local freenet would be tremendous experiance for those involved in the set-up and administration efforts, as well as those enjoying the effects of local broadband survice. I sincerely hope that more technology inclined people show an interest in this type of connectivity.

  7. Sounds great but... by Illserve · · Score: 4, Interesting

    If my cable company found out about this somehow, they would pull by connection so fast, half our house would go with the wall plate. Then of course I'd be stuck because there's not a terrific variety of reliable vendors to choose from in our neck of the woods. So it would have to be low-key, somehow.

    Besides, more than a few people would likely saturate the upstream on almost any cable modem and many DSL's. Any words of wisdom for those of us with 10 Mbit pipes running into our house?

    How about, for example, a peer-peer setup with multiple cable modem gateways splitting the load?
    Would that work with multiple base stations?

      True, but hiding from the cable company isn't that difficult. There are a number of solutions out there to make your tcp/ip stack look like that of a Windoze or Mac box. If you're using some form of NAT'ing, the cable company won't even see your network. Sure, there are some more sophisticated ways of sniffing out NAT traffic, but is the cable company REALLY going to invest time and money to bust everyone doing it? Probably not.

      Besides, with the advanced routing techniques available to Linux/UNIX/BSD style boxes, you don't have to be the sole upstream provider. You can peer amongst other Wireless users that have a full/part-time connection to the Internet. Imagine redundancy over multiple users whose ISP's in turn have redundant connections over multiple networks using diverse methods of connectivity (Cable, xDSL, Modem, Leased Lines, Wireless, T1/T3, etc). Add in QOS rules to classify, route, and limit traffic. If one of you gets picked out for incorrect bandwidth useage, you're not out of the game. You may have added latency and reduction in local bandwidth resources, and your community members would have lost a fraction of their total bandwidth. Guess what, you still win; you're still connected.

    I want to setup a wireless network similar to this, but I wouldn't get my bandwidth for free so I'd have to charge a small fee to cover the cost of the T-1 or T-3 line. The main problem I saw was distance, sure I could put up a powerful antenna on my home, but what about everyones wireless cards? I figured I could transmit to them, but I figured their little antennas wouldn't be able to transmit to me unless I also put up a powerful antenna on each home.

    Does anyone have some ideas about how I could do this? The chaining of access points sounds like a good idea, but there is the routing issue if one goes down, not to mention to cost factor of having one in every home, maybe one every couple of homes to keep a fairly tight network. Could someone point me to a good resource that describes how I could setup a network like this and make it work well? What about FCC regulations on doing this type of thing? Ideally, in the future, I'd like to provide a wireless type service to my whole town, are there any regulations for using a standard wireless network for profit like that?

    I have so many questions about this type of network setup so if you want to e-mail me the answers and maybe we could talk off-slashdot, that'd be great too. My e-mail is pretty easy to figure out since there is no JeffSketch.com domain.
