With luck, you have found this site via either my original Stompbox How-To or the article I wrote for Make: Magazine. I've put up these pages under the stompboxnetworks.com name as the original URL (moro.fbrtech.com/~tora/EVDO) was rather ugly. All the old project pages are mirrored here now.
If you just wandered in here from a web-search or a curious click, you may be wondering just exactly what a 3G/Wifi StompBox is. A Stompbox is a home-brew WWAN (Wireless Wide Area Network) router. In more human terms, it's a compact little box that gets data from cellular towers and re-shares it for multiple computers to use.
To use it all one does is plug it in to the cigarette lighter of a car (or a 12v supply when at home). It automatically boots up and links in to a cellular data service, turning itself into an access point. Turn on your laptop, join the network and voila -- you're on the net! It's just like using a hotspot (such as they have at Starbucks and airports), but it goes anywhere you car goes. Some people have even hauled them around in backpacks to make themselves into a walking network access site.

I've actually built one of these from the original pages that were posted on the project back in the spring. It works well and has come in very handy.
