"The information technology revolution holds tremendous potential for addressing problems in developing countries," said Eric Brewer, a UC Berkeley professor of computer science and director of the Intel Research Berkeley lab who initiated efforts to develop the technology. "Historically, though, most projects have been either too expensive or too technologically complex to be used in poor, rural areas. What we've done here is develop a simple, inexpensive software and hardware system that can provide villages with a high-bandwidth connection to computer networks in cities as far as 50 miles away."
