Comcast To Expand Public WiFi Using Home Internet Connections

Bob the Super Hamste writes "The St. Paul Pioneer press is reporting that Comcast is planning on expanding its network of public WiFi hot spots in the Twin Cities area by using home internet connections and user's WiFi routers. Customers will be upgraded to new wireless routers that will have 2 wireless networks, one for the home users and one for the general public. Subscribers to Comcast's Xfinity service and customers that participate in the public WiFi program will be allowed free access to the public WiFi offered by this service. Non Comcast customers get 2 free sessions a month each lasting 1 hour with additional sessions costing money. The article mentions that a similar service already exists and is provided by the Spain-based company Fon."

      You connect and then you have to login. No login means no route to the internet.

      If someone else is already using the "public" side of the access point when you want to connect then you could probably hijack their session by cloning their IP and mac address but if only the "private" side is in use that option is ruled out.

      No... it maybe a separate ATM channel or something used for low level encapsulation by DSL service, but it still has to run over the same Signal-to-Noise ratio that is possible for the physical DSL line BT use between the DSL modem and the exchange.

      So indeed you have the share bandwidth, since the public side will be eating bandwidth out of the maximum possible bandwidth for the given signal-to-noise ratio of the physical line. Well this is true for ASDL2+ services (upto 24Mbit) that have historically run most BT.Fon access points. If you are 8 Kilometers from the exchange maybe you can only get 2Mbit services, where as if you are under 500m you can get over 20Mbit.

      Now BT have an VDSL service running 100Mbit and maybe more, I am not yet lucky enough to be able to order this service as the exchange upgrade cycle has not yet completed in my area. In this scenario it might be said that it doesn't matter if the public side eats some bandwidth since there is plenty for 2+ people to stream video. A single user can easily max out a 24Mbit services for some periods of time.

      I already do this, using my own cable adapter and my own router. And it is free for my neighbors and passersby to use. No charges from Comcast or anybody else. I do it as a free public service.

      And you have NO LEGAL LIABILITY for strangers using your Wi-Fi to perform illegal acts without your permission. Any more than an "internet cafe" does. People use it as they please, and they are responsible for their own actions. There have been many, many court cases over this by now.

      Think about it. If somebody came into your yard without explicit permission, grabbed your lawn de-thatching tool, and hit somebody over the head with it, would you be "liable" for murder? Hell, no. Nor are you liable, generally speaking, if you (legally) loan someone your gun and they shoot somebody with it. Unless of course you knew their intent ahead of time and loaned it to them specifically for doing that. But we're talking here about somebody doing something without your foreknowledge.

      So why should a router be any different? (Hint: it isn't.)

      By the way: the EFF recommends doing this as a courtesy to your neighbors and the public, and assures you that there is no liability.

    Yes. The kick back is that you get to use all the other wifi hotspots that are setup the same way by other customers for free (or, as part of your package). It actually seems like a decent little "give some, get a lot back" type of setup, except the part where they allow random users that aren't contributing hotspots to the system (but they do charge them and, at least hypothetically, that could be going towards maintenance/bandwidth/etc**).

    ** no, I'm not naive. This is the part they want to profit off of. The mutual agreement to share wifi networks could have been setup by anyone without a carriers involvement, or they could have set it up without an additional profit motivation, but that's not the case. This gives them a selling point; it keeps people from putting money into other networks pockets (keep them on comcast networks); it widens their grasp; it's a cheap grab at a potentially giant amount of wifi hotspots for nearly free; and it's a potential money maker on people that aren't participating; and later one, they can flip the switch and upcharge existing customers.
