Mobile WiMAX to Succeed Where Muni WiFi Failed? 93
WiNot writes "WiMAX's supporters are positioning Mobile WiMAX as an alternative to municipal WiFi networks in the wake of recent cancellation or postponement of muni WiFi projects in Chicago and San Francisco. 'There's no business case for municipal WiFi ... With many municipal WiFi deployments in a holding pattern, it may be Sprint's Xohm WiMAX network will be up and running before muni WiFi can get its act together.' From what Ars saw during its Motorola-sponsored cruise on the Chicago River earlier this week, WiMAX has the potential to deliver the goods in terms of speed, latency, and reliability. If Sprint hits its goal of blanketing metropolitan areas with WiMAX in a timely fashion and prices the service attractively, the kind of expansive municipal WiFi networks once envisioned in Chicago, Houston, and San Francisco could go the way of Pets.com and Flooz."

I once got involved with a group of people who wanted to deploy a system like that; basically a mesh network of wireless nodes. There was a linux distribution around that turned a computer with a wifi card into a mesh node, doing all sorts of neat intelligent routing. You could have multiple uplinks in the mesh at various points and packets would automatically pick the best route, it would route around damage, you could use cards with multiple wireless NICs to do long-distance WiFi point-to-point connections (although using external antennas with consumer wifi gear is technically a violation of FCC rules).
Unfortunately what hobbled the system was the limited number of Wifi cards supported by Linux. We wanted to use donated hardware and most of the wireless cards we could acquire cheaply weren't compatible. The situation might be better now (this was 4-5 years ago).
The main problem with Wifi or any other very low power system is that you need a LOT of nodes. That's why WiMax looks better; it can use higher power levels and thus you need a lot fewer nodes.

Figure out how much muni WiFi would have cost, total. Then add up all the future private company bills for service. Yup. We're screwed. I've always said that the real cost is the TOTAL charge for every customer since the inception of service, added up. It's fun to figure out how much a taxpayer-paid nationalized internet would have cost, and then add up every wireless, cable, telephone and DSL bill since the beginning of private service. Ans: we've been massively overcharged.
Do we pay for roads like this? Airports? Harbors? Altho it's interesting to note that embedded GPS and cell systems have led to a pilot project for a state to charge your car per mile driven. So we'll get it both coming and going, first taxes and bonds, then a usage charge.
The ultimate question is: where is the money going? Who's making billions unfettered by regulation?
