Green Bank, WV, isn’t exactly the kind of place you'd expect to find world-class high-speed Internet. Nestled in mountainous terrain, the tiny hamlet has a population of fewer than 200 people. As is common in many rural areas, cellphone service is unavailable for miles, but Green Bank has a rather unique communications problem: even radio transmissions are strictly limited to avoid interference with a federal astronomical observatory nearby. Green Bank is a place where many residents literally live off the communications “grid”.
