    One of the great things about DSL is that you have your own connection to the ISP, as opposed to cable modems, which share bandwidth within each neighborhood. With this scheme, it looks like they are using each subscriber as a relay, so your bandwitch is shared with anyone upstream from you. This can be good for business, but not so great for consumers.
    • by RC514 ( 546181 )
      Yes, but typically a DSL connection is not using the maximum possible bandwith. They probably use a fixed part of the bandwith for the paying customer and any excess bandwith is allocated to the wireless access point.
      • A local ISP in the "telecom valley",, is offering another type of weireless broadband called "rooftop []". Afaik, it doesn't piggyback other user's connections on top of yours. It sure is nice to see so many local broadband options in my area.
        • oops. I was mistaken. Further reading revealed it does actually get access from other users. Oh well. ;-(
        • This is the same thing. I was misled by the "Rolling DSL and Wireless Access Out In One Swoop" headline. Nevertheless, I think that using otherwise unused bandwith from customer DSL lines (the difference between what the customer is paying for and what the DSL-modem is capable of) to provide wireless access to an area is quite an intriguing idea.
          • does anyone have EXTRA bandwidth ? is kind of like extra money. I know I use every kbps on my sdsl line. 768 seems like a big amount but goes really fast.

              DSL is capable of several MBits/s. There are different types of DSL, but for ADSL, an FAQ [] mentions up to 8 MBit downstream and 1 MBit upstream. Since residential customers usually pay for and get less than that, there is extra bandwith which could be used for providing wireless access.
    • I may be showing my ignorance here, but does this mean that each subscriber is going to be broadcasting WiFi to the neighborhood?

      Doesn't this make the whole network more susceptible to wireless attackes by AirSnort and WEPcrack technologies?

      Or am I on crack?
      • by RC514 ( 546181 )
        If they do it in a responsible way, they split the bandwith (x MBit for the customer, rest for the WAP), but without sharing the broadcast domain. DSL modems usually have an ATM mode which could be used to create separate channels, guaranteeing QOS to the customer and keeping the wireless traffic away from his network socket.
        • The QoS may be there - while I was under the impression that current traffic maxxed out the DSL pipe, I'll just assume I'm mistaken - but that still doesn't explain how Vista is going to protect their own wireless traffic nodes (forget the end-user) from mobile attacks.

          Wouldn't they have to deploy high-end security for each router that gets an antenna to prevent every deadbeat with an 802.11b device and some sniffing technology from surfing for free?

            Sorry, now I get it. I had thought they wanted to provide a wireless network as a bonus to normal DSL. Stupid me. I guess I'll watch the demonstration [] from Nokia before I continue commenting.

            Ok, looks like the article is a little misleading. "Wireless coverage" is not really the goal of this approach, but merely the means to provide residential broadband internet access. It makes connecting distant customers feasible because up to 40 subscribers can be connected to one one "airhead", which is a special box connected to an uplink, which in turn can be either wired or wireless (but not through other airheads). The cost of installing an uplink can therefore be split among 40 customers, and because the "airhead" is so small, renting an office for hub hardware isn't necessary. This whole concept doesn't appear to be based on 802.11b at all.

    • That's also what it seemed like to me when I read stuff. But I don't think it's that simple. With the cable modem you send your packets thru a neighborhood hub, which then goes to the company and out onto the web. With this system I don't understand how they could coordinate that, and it doesn't seem right to me anyhow. Would the system keep a listing of all people connected and then go thru the fastest route? Would it only use systems that are not sending or recieving data? For some reason I doubt that this setup would fly, especially due to the capacity for security problems. What if you were able to configure your system to catch all queries relayed thru your box? Personally, I can't wait to inform my buddy about this. He's 220 feet outside of the area that he might be able to get DSL to, and Pac Bell sucks. This has the potential to be great for a great many people. - DaftShadow

      Yes with DSL it is true you have your own dedicated connection, but that usually only goes as far as a local collection point - it certainly is not a dedicated amount of bandwidth right to the ISP, nor to the Internet.

      The only difference with cable is the proximity to the individual customer at which the sharing begins. Peak usage times on DSL introduce just as much slowdown to the user with his "dedicated" pipe as they would to the Cable user with his "shared" pipe.

      I understand that your point relates to the sharing forced up on the user by the reselling of the wireless access which is sure to come, but the shared/dedicated differentiation between DSL and Cable is already misunderstood enough by Joe Sixpack without this added complexity.
      • Another point to make-- my local loop of cable is fed by fiber. Who's more likely to get fiber to my curb, the cable company or the phone company?

        I disagree with your point about DSL and cable being lagged at the same points.

        I have both DSL and cable connections at home. I'm 3k feet from my CO, wire-distance. My DSL is set to 5mbit down / 1mbit up. Cable is 2mbit down, 384k up.

        In my neighborhood, there is a very high concentration of customers terminating on the local cable node. When I last spoke to a contact I have at the cable company, he said that there were over 4 thousand connections from residences to the node. That node is connected via a single 45 mbit ATM DS3 to a regional ATM concentrator, then to the main office, which connects to the net over a singe 45mbit DS3.

        As for the DSL connections at the serving Central Office, mine currently has about 1100 DSL lines connected to the DSLAMs located there. Each DSLAM is connected to the local SONET ring by an individual 45mbit ATM DS3, which each then connect into an ATM concentrator, and from there to the main office, and out to the Net via dual 155mbit links.

        Raw performance in off-peak times isn't applicable, due to the speed of both connections. But during peak times, I'm lucky to get 20k/sec on the cable link while downloading a test file from the cable company's FTP server. The same test on the DSL network yields about 450k/sec duting peak times. Accessing the internet yields similar results.
      • quote: "Peak usage times on DSL introduce just as much slowdown to the user with his "dedicated" pipe as they would to the Cable user with his "shared" pipe. "

        That isn't very accurate. Every DSL customer has a guaranteed amount of bandwidth to the CO, which starts getting shared from that point on. Depending on how the telco has set up their network, the CO may have more than enough bandwidth to be non-blocking all the way back to their core. From there if the customer is accessing stuff that is on the telco's network, or that the telco has direct high speed links to, there will be very little slowdown even at peak times. Access to the Internet will probably be slow due to oversubscription of their PoP links, but that is pretty much to be expected.

        This differs from cable in that everyone in a neighborhood node shares their bandwidth right from the start. That means that at peak times, the customer could experience slow connections even to something on the cable companies local network.

        Granted most people probably don't do much of anything that is on the local companies network, so the essence of what you said is true. On the other hand, if people use the companies caching proxy server to access web pages and are just looking at the standard static content for the most part, DSL subscribers are likely to be much happier than cable users.
    • That thing about having your own connection with DSL is much overrated. DSL hits wire limitations so unless you live right next to the CO, your bandwith will be quite limited. Now coax cable can carry a much bigger amount of data than twisted pair, I think Docsys standard says something about a max of around 30Mbps. It's up to the cable company to make sure they don't oversubscribe the nodes. So it happens that my cable connection goes 3000-4000 kbps down and 950 up, and I'm talking peak time. Compare this to the 600/90 DSL line that's available in my area.

      I guess it all depends on the company and how much they value customer satisfaction. The only DSL ISPs still standing are the big telcos and we all know how customer friendly they are.

      It's all shared bandwidth if you look at the larger picture. With DSL, each person has a dedicated line to there house....but only from the CO. Once the line gets to the CO, then it is combined with many other subscribers and passed on to the fatter pipes. Several DSL subscribers can still suck most of the bandwidth. So what if you are guaranteed a 768/128 or whatever to the's beyond the CO that matters.

      Cable does share the bandwith among the neighborhood, but it usually (or at least is suppose to be) partitioned off into smaller neighborhoods once one gets beyond the capacity.

      See here [] for more of an explanation and other DSL/Cable myths. Yes it is from Cox cable, and yes the do have a vested interest in trying to get you to subscribe to cable service, so take it with a grain of salt. But for the most part it is true.
    • "One of the great things about DSL is that you have your own connection to the ISP, as opposed to cable modems, which share bandwidth within each neighborhood."

      Uh-huh, and does this make your DSL line any faster than a comparable cable modem? Take a look at the results of the DSLReports speed tests [] -- nearly all of the top speeds belong to cable modem networks.

      I had DSL from Speakeasy -- 1.5MBps down/384K up. Great service, but it was $100/month. My $35/month cable modem has the same download speed. I get 1.5MBps down, period. It's not dependent on how far I am from the cable company, either.

      You have a point, but the fact that your bandwidth isn't shared doesn't make a difference in your overall speed. This is just something the DSL companies came up with to try to differentiate their more expensive service from the cable modem crowd.
    • Who said they are using YOUR bandwidth? Isn't it possible that they run two lines to your house, one is yours and the other belongs to the AP. I wouldn't trust my connection if anyone with netstumbler could get to my internal network and I'm sure that they wouldn't trust letting you have the ability to monitor all subscribers that connect through your AP.
    • Someone else mentioned this, but it wasn't obviously stated. The ISP could give you a 1.5Mbps/384kbps bandwidth to your dsl instead of the 384kbps/128kbps that they are claim. Using bandwidth throttling they could keep you in line and you could support a few more people coming in on wireless.
    • This is technically true, and one of the reasons I always preferred DSL. But in practice, a Cable Modem is a pretty phat pipe, at least here on the Palos Verdes Peninsula (California / Cox). I regularly get 300 K-bytes per second downloads (yes, that's 2.4 megabits/sec). Nothing like getting 1/4 10Base-T Ethernet speeds.

      That's compared to the 384kb DSL that I used to pay twice as much for at my old pad.

    • One of the great things about DSL is that you have your own connection to the ISP, as opposed to cable modems, which share bandwidth within each neighborhood.

      Everybody (most notably DSL providers) is quoting this as a downside of Cable, and an advantage of DSL.

      I share something like 2Mbps with my neighborhood. From the central office of my cable company I still share the link with the rest of the customers of my ISP. My cable provider caps me at 512mbps.

      ADSL customers have their private 6mbps (but capped to the same 512mbps) link to the ISP, and then share a similar link with the other customers to the "rest of the internet".

      No provider will tell you what the capacity of those links are. And they won't tell you when and how much they are congested.

      What I do know is that on average, I get (slightly) better download speeds than my friends with ADSL.

      I deduct from this that at the moment, my Cable provider has a better internet link than hte averate ADSL provider out here, and that my local segment isn't very crowded.

    Residential wireless is neat, but only if you can't get DSL or a cable modem. The latency makes it problematic for fast-paced online games, but the download speed makes it ideal for web surfing. Also, wireless usually has a transfer limit -- in this company's case, it's 3GB-6GB a month (3GB for the lower-priced connections.) You have to watch your downloads.

    It's a great idea if your only choice is dialup, and I'm glad to finally see a company recognize that this is a great service to those in flat areas that DSL/cable are not covering.

IMO, having been one of the engineers for NorthPoint and now AT&T, it is refreshing to see a company address these markets with a topology that has the potential to turn a profit for them, as opposed to the standard approach of rolling out services at a loss to satisfy availability claims.

    Does anybody have an definitive answer as to how these wireless devices stand on the FCC's "totem pole". I was under the impression that us ham radio operators (at least for the part of the spectrum we share with 802.11b, about 1/2 - 2/3 of the channels) were given a higher priority than the ISM unlicensed users. In fact my license gives me the ability to jam out 1500 watts with no limitation of ERP. So my spread spectrum 5 watt signal at 2.406 mhz sent through a 15db vertical is going to cause them at least a hiccup if they ever make it down to Florida. (my signal is audible enough to digipeat at 23 miles from my house. (yikes, too bad I can't make money off of it...)) What would happen if say a company wanted to use the same frequency my station is set to? In the past hams have usually been trod upon, as the primary users have priority. Does this actually mean they have to work around me for once?!
  • Feb 7, 2003 -- In other news, the mean air temperature around Petaluma/Santa Rosa has risen 2 degrees in the past year, scientists say. This has absolutely nothing to do with the widespread deployment of microwave towers throughout the area, according to a Vista Broadband spokesman. He added, "It's also completely unrelated to the purely coincidental increased cancer rate in many of our subscribers houses."

  • I live in a sub division that has, untill recently, been way to far out of reach of broadband. Even if it would be shared bandwidth, as has been pointed out, it would be VASTLY better than the 24.6kbps modem speeds we get here. Plus my subdivision is full of multi million dollar homes: ie people with MONEY TO BURN. They would make a perfect test market. In a place like this, most everyone has a computer, and so you could test the system very well. It is a market like this where they will be able to make REAL money. But for us it's too late. We got cable modems about 10 months ago, and we should have DLS within about 6.
