As many are aware, there is a digital divide in this country. In a vastly oversimplified nutshell: The haves have broadband. The havenots try phone based ISPs and decide it isn't worth the hassle.
I was recently pondering the idea of having a single wireless access point for a city block. Could this be used as a cheap alternative to cable. No per household wiring. Wireless cards are cheap. The bandwidth would be shared and hence could face contention, but you would not have to sit and wait for the phone to dial and connect.
Is the technology good enough to make this feasible?
