Being Wireless: Viral Telecommunications

802.11 + VoIP = Bye Bye Cell Phone

[mhesseltine]

Unless, of course, Verizon, T-mobile, Voicestream, etc. "influence" their favorite congress rep and get some BS law passed claiming that VoIP on 802.11 is so cheap and available that the terrorists will use it to coordinate missions. And then, when someone uses your hub, you are now responsible for aiding terrorism.

On second thought, forget I ever posted this. Those bastards don't need any more ideas.

It has potential, but...

You need a fundamenatly different method of IP addressing, new routing protocols, and methods for interacting with the current net as it exists. Do you think that IANA will easly start putting out IP addresses for Mesh networks? Even with IPV6? The hardware is there, but more work needs to be done on the practical implementations of mesh networks and integrating them into the current infrastructure.

Then lets consider how ling it will take the "Bells" to wake up and notcie that thier stangle hold on the local telco market is threatened. It will not take too long for Congress to churn out some back-assward laws that stifle any creative use of Wi-Fi.

Problems with this concept

He mises one crucial point, the backbone, this posting for instance isn't going to magically bounce from the middle of the UK to Exodus(?) by 802.11 alone, as illustrated by the recent crackdownby cableco's on publicly listed access points they're reluctant to support an essentially public network that runs contrary to their business model, and transcending the traditional backbone requires organisation and capital, something absent from P2P systems.

A concern is the finite amount of spectrum available in regards to the scalability of P2P wireless systems, as the number of users increases so does the baseload just to maintain the system, some clever managed routing will be required along with a wired backbone between nodes, if you use daisy chain style off-air repeating between nodes you quickly deplete spectrum and diminish the benefit of local frequency replication, basically the "everyone shouting in a crowded room" scenario.

"Distance decay" is a feature of the traditional phone network yet on the net people no longer communicate on the basis of geography, did that Wired article come from a server in Silicon Valley, New York, London? Does it matter, I don't particularly care, I'm just interested in the content. However the "lily pads and frogs" architecture is deeply tied to locality, it's easy to communicate with local nodes but it progressively gets more difficult the farther you go, again this leads us back to the backbone problem.

Another issue is misuse, free wireless reminds me of the net of yester year, you could for instance use SMTP servers all over the globe and the vast majority of users didn't abuse that facility, but obviously the small majority of spammers swiftly made that a thing of the past and continue to annoy us today, how would open wireless networks be any different? Control is needed, which leads back to structure and capital.

Call me a pessimist, but it's not quite as rosy as he makes out.

Already happening in my town...

Check out http://reseaucitoyen.be/, a project in Brussels that has been pushing this idea for some time.
It's in French. Translation: take a WiFi card, attach an external antenna.
Next, take an old Linux box, turn it into a router.
Aim towards another node, and you join the network.
Security is easy: treat this segment as being unsecure and use your existing firewalls.
Basically such an architecture creates a public infrastructure on which all kinds of services are possible.
It's cheap, robust, and a serious threat to the telcos.
Negroponte is right: 3G is the Telcos trying to define the future, when the future is busy happening somewhere else entirely!
