Flexible Optic Fiber Promises Cheaper Last Mile 161
bn0p writes "Ars Technica has an article on a Korean company that has developed a low-cost, flexible, plastic optical fiber that could bring cheaper 2.5 Gbps connections to homes and apartments. While not as fast as glass fiber, it is significantly faster than copper. In related news, Corning recently announced a flexible glass fiber that can be bent repeatedly without losing signal strength. The Corning fiber incorporates nanostructures in the cladding of the fiber that act as 'light guardrails' to keep the light in the fiber. The glass fiber could be as much as four times faster than plastic fiber. Neither fiber is available commercially yet, but both should help with the last mile problem when they are deployed."

That's pretty much it.

Unless you've found a free supply of commercial grade wifi routers, free connections for them to a backbone, volunteers to do all the installation, etc.
If the trench (pipe, tunnel, etc. depending on location) already exists then installation of wired connections can be far lower than than wifi - and installing a fiber bundle gives orders of magnitude more bandwidth availablility == more options to make your money back.

Err, no. Wireless is very expensive to install. Even more expensive perhaps than mobile phone networks (mainly because you need 50-100 times more access points than you need for mobile phones (due to the very low transmission powers the standard permits).
Why do you think that there are almost no cities with city-wide wireless access, years after the technology became prevalent? Most people have problems getting WiFi working in their house - let alone trying to get it to work for a whole town without all the channels massively overlapping. Municipal WiFi won't take off until the standard (perhaps a NEW standard) allows higher transmission powers and a larger frequency band for extra channels.
