Why is that cool? Its basic population density. There are more people per square mile in the east than in the west. It costs a heck of a lot more money to deploy service when your customers live miles and miles apart!
Or less. Wireless gear is pretty cheap these days ($150 for a radio + antenna etc.) however it requires relatively clean spectrum. Which is available in rural areas where you don't have the nation's largest WiFi network at your disposal (linksys).
