Can Mesh WiFi Solve The Net Neutrality Issue?
from the not-likely dept
We've pointed to two separate, but equally insightful, pieces on the real issues concerning network neutrality (which is, basically, that network neutrality isn't the issue -- a lack of competition is). The first piece was by Tom Evslin and highlighted why you can't trust either the telcos or the regulators to do things right. Then, yesterday, there was the piece by Andy Kessler, suggesting we go after the telco-owned networks to force the telcos to generate some real competition. Evslin has now come back and written another long post about the situation, in part responding to Kessler's piece while also filling it in with some ideas from an event he attended. He comes up with a two part solution to the competition issue and net neutrality. First, instead of talking about net neutrality, he suggests focusing the debate on America's Antiterrorist Network. The idea being that, if we actually had better, faster, more reliable broadband networks we'd actually be able to do a much better job protecting the country (economic boosts would just be a side benefit). Of course, in some ways this seems on the same level of propaganda as the two main players in the debate over net neutrality keep rolling out.His second suggestion is perhaps more problematic. He's betting on mesh WiFi as the answer. In fact, some of the telco supporters (the same folks who used to bash muni-WiFi) now point to such mesh WiFi efforts as proof that there is real competition already in the broadband market. If only it were so. As some of us have been pointing out for years, WiFi technology really is not designed for this sort of usage -- and early results have supported this position. Story after story after story highlight how wide-area WiFi is a lot more complicated than many in the industry (and the press) would have you believe. However, even if these networks worked flawlessly up to expectations, it still wouldn't be an answer to the net neutrality issue -- because even a perfect WiFi network can't handle the same level of usage and doesn't come close to providing the bandwidth of a fiber network. We can hope that other wireless technologies will be the solution -- but so far none of the upcoming technologies have been shown to be even remotely effective in competing with a fiber line. Cellular networks are cutting off users who use over 10 gigs a month of bandwidth, claiming it degrades network performance. If it can't handle that much, it's not a real competitor to DSL, let alone fiber. WiMax still has a long way to go before it shows it's a viable technology at the same scale -- and even then there are spectrum allocation issues that need to be dealt with. Meanwhile, Tom Evslin, himself, explains why satellite also doesn't represent real competition in the space. We can still hope that future generations of these technologies will be much more competitive -- but we're talking many, many years (and even then, it will still depend on spectrum allocation issues). So, using anti-terrorism as a peg for fighting for net neutrality may be useful in stirring up some debate -- but betting on mesh WiFi seems like a losing bet.
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

Mesh and Radi
As an answer to the quasi-questions in comment #2, one of the biggest problems of Muni WiFi is that the signals are ALREADY too high powered. There are only 3 distinct, non-overlapping channels in WiFi b and g at 2.4GHz. Boosting the power of public networks beyond the legal limit, which they already use, would cause a great deal more intereference on all other devices using the 2.4MHz spectrum. Think of cordless phones, baby monitors, remote surveillance cameras, and existing WiFi LANs inside houses and offices. The current FCC laws (and a fair use of the unlisenced spectrum) would not permit that kind of destructive interference. Other logistical problems would come up, like who gets the licenses. Well, auctions could solve that, but who wants to bid for the right to broadcast high-power, yet over unlicensed spectrum? That's still a risky investment. Next problem is that even if the towers are very high power, the CPE is not. That means that although you can hear the tower, the tower doesn't "hear" your laptop. Your laptop will report a strong signal, yet you won't understand why you can't connect. Jack up the output of every CPE out there, and you have significant cost increases, battery life decreases, and you'd have a cacaphony of interference in the three 2.4GHz channels, and basically nobody would be satisfied.
What's the fundamental, underlying problem here? The techology is using unlicensed spectrum. To do so inside your own four walls with low power works great. To do so outside of your four walls, and at higher power means interference beyond your control.

Unlicensed spectrum is not a defect, it's a feature. You just have to use it intelligently, in a highly focused way.

re: phased array
wifi technologies have been around for a number of years, as have dsl / cable. although true that wireless has improved over this time, and speeds have improved, interference issues are largely where they always have been, and prices have not significantly dropped (except for clearance equipment, which does not include the features you say will save the day)
incidentally, dsl and cable have also improved during this time, and at roughly the same rate. because dsl / cable are wired technologies, they do not have to have complicated signal processing to deal with free-space interference and losses. and because they are wire based, they have access to as much analog bandwidth as the wire can physically transmit, which is quite significant compared to how much analog bandwidth you can use in a wireless setup without expecting interference from others.
in other words, wireless may get better, but it does not get better faster than wired technologies, and therefore will remain a niche market because of its high price, low reliability, and low bandwidth.
you could say "but once this awesome technology / fcc regulation is passed, wireless will rule for all ever!"
or you could say, that once there is a wide scale deployment of fiber, that wireless will be forever relegated to niche markets.
i dont see the killer wifi technology development or regulatory hurdles being passed happening near as rapidly as fiber is being deployed.

Network
however, I believe wireless technology is the future. Why lay down fiber lines when you can just send a signal through a different medium, the air/space. After all, a wireless signal is just a lower amplitude wave than light, and one day we will figure out reliable and long distance wireless communication.

Use either 5GHz or a licensed proprietary band for the backbone.
Each "tower" would have its own channel to recieve on, while it must be able to broadcast on up to 4 or 5 other channels simultaneusly.
Each "tower" connects to at least 2 and preferably 3 other towers.
"Towers" would act as routers seeking around down towers and congestion.
Each "tower" would have a high power (around .5 - 1.0 watt) omidirectional 2.4GHz radeo.
Each "client" would have standard hardware equipped with high gain directional antenna's
said system would have little overhead and could support around 100 - 250 users per radio / per tower (according to specs of 802.11b) while maintaining a dedicated back bone. backbone equipment would require special programming and perhaps proprietary hardware.

All in all the cost for a 54 sq mile area is still beyond the realm of most organizations and is really not justifiable at this time.

Phased Array For Strategic Results
That is where Robert T. Morris has gone wrong with his Roofnet Project at MIT. The Roofnet Project is too democratic, and insufficiently aristocratic.
http://pdos.csail.mit.edu/roofnet/doku.php
Morris is spending too much time worrying about how to hook people up for a hundred dollars each, and his core constituency seems to be the impoverished student living in an apartment rented from an urban slumlord. That is all very well, but it leaves Morris bottled up in the urban slum district. Roofnet as presently constituted is tactical, not strategic.
For strategic results, you have to make it fun for the participants. Given the right circumstances, phased array WiFi equipment might be able to reach out for twenty miles. Again, given the right circumstances, a very small number of elite enthusiasts, a hundred or so, might be able to run a megabit link from Florida to Quebec, probably along the line of the Appalachian Mountains.

Wifi mesh
Althoug WiMax may not be perfect, it is much better suited to performing this task and (in my experience as a WiMax provider) does it not ony well, but with ease.

Mesh WiFi
Mesh WiFi is only as good as the ISP's backbone. Lets say the ISP is operating on a T-3 or T-4 network - then it would be really nice! Mine is operating on a T-1 line. Still it isnt that bad - about like low grade DSL.
My ISP operates on B protocol which in my opinion isnt as good as N protocol which overlaps and gives the same range - all with the added speed of N. I think that if he internet were entirely wireless then N protocol would be the way to go. There are a lot more cordless phones and other wireless equipment that operate on 5 ghz spectrum. If we could reserve the 2.4ghz for WiFi - that may rid the problem of high powerd licensed towers for the backbone.
For the home user to get onto the backbone - they would still rely on the 2.4ghz low power towers but these arent really that bad especially if I had my way and they broadcasted on wireless N!
