I've been hearing a lot about WiMax, and thi article,Mobile 'hot spots' push limits
from the St. Paul Pioneer Press explains how a Twin Cities tech entrepreneur has retrofitted an old TV-station truck to serve as a roving hot spot for Internet access. His technology firm has blanketed the metropolitan area with WiMax transmitters atop local skyscrapers.
"DeVaan's modified van performs a similar trick. Its mast communicates with any of the wireless-Internet transceivers Implex.net has put atop Twin Cities skyscrapers, including Wells Fargo Place in downtown St. Paul and several in downtown Minneapolis. Presto! The van is Net-connected. All DeVaan has to do is plug in his Webcam and point it... In addition to serving as a roving eye, the van can provide high-speed wireless Internet access within a 1,500- to 2,000-foot radius."
What a great idea.
