DIY phone and internet service for rural areas
Kurtis Heimerl enables entrepreneurs to build their own wireless networks. A postdoctoral student at the University of California at Berkeley, Heimerl packed a Linux computer, a 900 MHz power amplifier, and a 2G cellular-network antenna into a microwave-size box called Endaga CCN1. It costs a relatively modest sum of $6,000 and is simple to set up: Plug in power and Internet, mount the unit to a tree or pole, and voilà: connection. Endaga can connect up to 1,000 people within a six-mile radius.
