    ... is a wireless network with absolutely no security so people can walk within a 3km diameter space and just hack in on a whim?
    • It's not so much the wireless network per se. It's more the connectivity to the rest of the world you want to secure- and that includes the laptops and other machines that are hanging off of the wireless network.

      Still, the same is true of the internet.

      Connecting to internet == connecting to wireless net

    • From the article: RoamAD operates with a multitude of encryption protocols in conjunction with its proprietary authentication systems that provides a genuinely secure wireless connection
      So we can't say that there is absolutely no security, but we also can't say that there security is any good either unless we get to look at it, which we probably can't since it's proprietary.
    • ... is an ISP who doesn't secure MY home computers so people can log on for a low monthly fee and just hack in on a whim.

      This isn't some person's private network... This is an experiment in making a large-scale wireless network to cover a city-scale area or beyond. Think of it as something similar to Ricochet. And if you use it, it's up to you to secure your machine... if you leave it unsecure, sure, someone will hack in.

      I'm wondering how they limit down access to this network, so only paying subscribers can get on. Will it be PPPoE? Or maybe MAC address-based authentication (only specified MAC addresses are allowed to get onto these access points). How do they do this on a large scale with >1000 users? Most access points only handle a couple hundred MAC address for that type of access.

      Sounds like a great idea though. Imagine eventually this 802.11b network spanning an entire continent, with little to no roaming or coverage gaps. It should be good for at least 5 years, until the average Internet feed for a home user becomes >11 Mbps, then they'll be needing to replace the infrastructure (or be smart now and just make the whole infrastructure combination 802.11a and b access point, to handle the 55 Mbps 802.11a gives).

      Get 9 cans. Set up 8 of 'em together at 45-degree angles, so they form a "wireless hub". Connect them all together and you can communicate in a 5-mile radius of your location. Now just find someone within that range who can get high-speed Internet access, and use the 9th Pringles can to connect to them.

      Then you could offer wireless access to others through your "hub", and all chip in for the cost of the service.

      • I am busting my butt trying to get people in Houston interested in something like this. Except, of course, that the ninth can doesn't point to an internet access point, but to another hub. And maybe the same for the tenth and eleventh cans too.

    • > what kind of unit is a sq/km?

      It's the inverse of km^2. 1 sq/km is a square with side length of one kilometer. This unit of measurement is odd in that it increases as the area described decreases, but it's popular in Bizarro World and on Slashdot Island (where hamburgers eat you, and people throw ducks at balloons, and caching is impossible, and trying to moderate fairly gets you banned. Huzzah!) Therefore 3 sq/km is 1/3 km^2. What the article describes is 3 km^2, which translates to 1/3 sq/km -- that's the real typo in this article's title, not the units. No...no, not the units.

      Nobody better tell this guy about the existing network of dial-up nodes that pervades almost every corner of every country on the planet...

      That shares with this one the need for client authentication, the prevalence of users with little knowledge of security, and the tendency of machines to come on and off the network.

      The only particularly significant difference, which will hopefully be mitigated by development and adoption of effective encryption, and which in the meantime has little relevance to the substance of the comment, is the relative ease of snooping.

    • Well, I, for instance, currently operate a public 802.11 node in Seattle. It has a DHCP server listening on it to pass out ip addresses with full internet access. The only access-control on that network is some restrictions in place to keep wireless users from accessing my internal network, and only inbound established tcp sessions allowed.. (to prevent my next door neighbour from running a warez server off my bandwidth. :) The only other piece of "access-control" is an HTTP proxy-authentication piece that wifi users just login with "public/public" to get internet access. No logging, no tracking, nothing, nada. So if you want to hack the gubbmint from my home network, well, then I guess I'm just up shit's creek.

      I am willing to accept the fact that not everyone will be kind in their usage of my public offering. By sharing something that I believe everyone should have access to, it makes me feel a bit better knowing that I have helped out the global community as a whole.

    Recently I investigated GPRS availability where I live.

    I can switch to a GSM network (Rogers/AT&T is rolling out GSM as we speak) and get 53kbps of always-on internet. Not fantastic, but not bad.

    Unfortunatly they charge per Kilobyte. Yes. You heard me, Per Kilobyte. Even a few cents per K it adds up quick and becomes pointless.

    Ok, so check out another provider. Ok, GSM/GPRS service as well. Always on, blah blah, $50/month unlimited. Ok, good deal. fine print: for 12 months. After that, who knows? They revert to their regular rates(?), which aren't any better than Roger/AT&T.

    Ok, so how about CDCP? Hmm, about $50/month but it's 19200 Maximum. They add compression, but that won't solve the whole speed issue. And of course, only works with appriopriate modem, dead end technology, etc.

    No wonder these companies can't recover costs... nobody will pay the rates they want.

    • When you use GPRS downunder, the bill shows you which tower you connect to and how much data got transfered.
  • Considering the availability of huge fucking 3G networks [verizonwireless.com]. Highspeed wireless shit that is available in even towns less than 120,000 population [monetmobile.com].
    • Uhm... WiFi is WAY faster than 3G. I can set up a WiFi extension to my existing network for about $500. Can't do that with 3G (GPRS/GSM what have you).

      WEP has security issues, but none that can't be overcome with some creativity (VPN perhaps?).

      BTW, WiFi is broadband, 3G is not.

      Geez....

      PS Nice Troll
      • True 3G is broadband, the soup of 2.5G that the US will get is barely broadband. 802.11b is 11Mb/s on a 2.4Ghz carrier. 802.11a is suprisingly(from the name anyways) a newer and faster protocol that achieves 54Mb/s with a 5.2Ghz carrier. 802.11g uses the same encoding as 802.11a but over a 2.4Ghz carrier and also achieves 54Mb/s but has to share the airwaves with 802.11b and everything else in the 2.4Ghz ISM band. All speeds are raw wire speeds and actual throughput will be roughly half to two thirds wire speed in ideal circumstances. At fringe reception distances all protocols will drop speeds to some fraction of the rated speed. Having too many devices on a channel or close together will also cause backoff storms similar to a broadcast storm on unswitched ethernet.
    • My dear Mr. L00zer,

      3G is low speed and it doesn't exist everywhere, nor will it be ubiquitous. There are a few popular places where companies are trying to roll it out, but the overall cost is somewhere north of $100 billion to get major cities hooked up.

      3G is microcell based, meaning that you have relatively high power transmission compared with Wi-Fi, but large enough cells that you have a lot of people sharing a very few available channels. Thus when more than a handful of people are using 3G data services, the 100 Kbps or 300 Kbps or whatever they claim today as a maximum is split down into 3K chunks.

      With Wi-Fi, because it's picocell, tiny itty bitty cells, you can typically increase density (and the equipment's cheaper and requires fewer towers or other spots to make work) and keep overall bandwidth closer to the 4 Mbps that most devices throughput.
  • This is good news. I have really been missing the BBS times! Now that these wireless unlicensed spectrum miracles keep pouring in, we wil soon be in the position to have enough users to drop down the bandwidth to effectively emulate the Hayes Micromodem 100 [syssrc.com]. Excellent!
    • You are kinda on to something...

      For those of you old enough, remember when it seemed like every town (even the small ones) had at least one BBS to dial into, and inter-node email through FIDOnet at night (long distance rates being cheaper)? Couldn't something similar to this be done with WiFi? Hear me out:

      Imagine if every individual set up a WiFi hub node, with some kind of high-gain omni, and kept it open. This hub is connected to a web server - and NOTHING ELSE. It isn't connected to broadband, or even to the individuals home network (or only through a good firewall). Basically, it is a lone machine.

      Others set up similar machines, people in the immediate neighborhood (both fixed and mobile stumblers) could "connect" at leisure, just like the old BBS's - except without needing major numbers of phone lines, etc. Maybe the website on the server could show how to build such a system cheaply, where other nodes are, and where intermediate nodes are needed to bridge gaps in an area. These nodes could then form a more "permanent" mesh.

      Ok, perhaps this is what is basically happenning already - but what many of them do is have broadband connections that aren't legally allowed to share. I guess what I am aiming for is more of a return to the grassroots local scene, and perhaps certain nodes could be "volunteers" to "FIDOnet" (just the term - not actual protocols, of course) packages of emails, etc, across the internet via broadband/etc connections in bursts, to other nodes that could disseminate the contents of the package. IE, make it as legal as possible - but still "open/free"?

        I am even willing to personally finance the first few hubs, just to get some momentum, but I just can't find anyone that cares.
    • Here's a good point. Back in the day, it *WAS* possibly to hack BBS's. Most of the time it wasn't all that easy, since there wasn't an internet full of script-kiddy solutions or a buttload of docs, but at times it was done. And yes, BBS's did prevail.

      Having large local Wireless networks doesn't sound like such a hugely bad idea, provided that somebody is willing to pick up the tab for the access, and maintain the security. Knowledgable hackers will probably get in for free, but that's true to a lot of situations.
      Doors and locks only keep honest people honest...

      perhaps the WiFi script kiddies should dedicate some time to learning how to create security instead of break it, it might get them some local recognition, and looks better on a resume...

    During the last few years cable companies and the like spent a lot of money laying the backbone of their networks. In the city the last part was getting old buildings wired. This to me seems like a bigger expense.

    A you have to interact with the customer a lot. Schedule times, get access to the building, etc. Then somehow wire the thing.

    I think an easier solution would be for these high speed providers to hook up key buildings in neighboor hoods with good wireless equipment. Then ship the modems in the mail to the customer and they are all set to go.

    Eventaully we need to start fiber or at least cat 5 through these building. Or rather run piping so re-wiring in the future isn't such a problem, time for new building codes.

    For rural customers, I would think a chain approach might be the best. House 1 is hooked up high speed and then relays to the next and so on and so on. Of course being on the end of the chain is no fun, but it might be faster then dialup.

    In my opinion, any company that sells a proprietary extension to a standard will most likely fail, esp. when the standard is free (free spectrum, free implementations, just buy the radio). After all, there are plenty of better, proprietary networking standards, but we all use TCP/IP.

I've been deploying a beta version of our software in-house, and although I may be a bit biased, it really is a boon for WiFi. Seamless handoff, multihop, the works.

      I might also point out we have a solution that supports mobility at highway speeds. From what little RF theory I know, doppler shift will kill 802.11b at anything over walking speeds. I routinely demo this technology to different companies on a local highway. And I can promise this, the tagline "T1 in your pocket" is all too apt. Even if driving around can be monotonous, reading /. while listening to internet radio (what's left, at least) at 70 MPH helps.

He said the farthest he usually has to travel on the MassPike to find a hotspot is 10 minutes away. Not much along the 395 corridor yet, though.
