eric brewer at his berkeley intel research laboratory

this is the voa special english development report.

eric brewer is a busy man. he is a computer science professor at the university of california, berkeley. he is also director of the intel research berkeley lab. there, he leads a team of students and intel company researchers on projects with new technologies.

one of their creations is a wifi-based long distance network, or wildnet. wi-fi is short for wireless fidelity. wi-fi connections, or hot spots, can be found in airports, hotels, coffee shops and many other places.

but wi-fi is designed for short distances. eric brewer predicts that most wildnets will only need to cover several kilometers of territory. yet, in venezuela, a network using wildnet technology and special software reaches over three hundred eighty kilometers.

each endpoint in a wildnet uses a router that takes only about seven watts of power. it can be powered by car batteries, energy from the sun or electricity from a local provider.
