Trango Broadband Wireless, a privately-held company founded in San Diego in the 90s, makes connecting to the Internet possible just about anywhere. Trango uses radio spectrum that doesn't require a license and requires just a base-station radio and a subscriber radio. A base station (access point) runs about $1,000, and a subscriber radio can go as high as $500. The system serves as a relatively inexpensive alternative to laying cables in hard-to-reach areas and in emergency situations, and can reach as many as 300 computers within a 10-mile radius.
