The New York Times has an excellent article on the now almost two decades old digital divide problem. Where the digital divide was once "who has dial up access and who doesn't," it is now "who has real high speed access and who doesn't?"
The article does a good job of outlining the challenges that face communities, including the citizens and businesses that find themselves on the wrong side of the digital divide. Of particular note is this:
"...it is hard to get a college degree from a remote location using wireless. Few people would start a business using only a wireless connection."
Fiber is the long term technology solution for both wired business and residential access as well as improved wireless and mobility access; what everyone forgets is that wireless networks have to move data and voice traffic onto the wired network, and robust open access fiber networks make wireless networks work better and makes wireless less expensive..
