The technology for wireless connection to the Internet is as old as the Net iteself. Amateur radio operators began "patching" into telephone lines with fixed, mobile, and portable two-way voice radios in the middle of the 20th Century. A wireless modem works something like an amateur-radio "phone patch," except faster. High-end fixed wireless employs broadband modems that bypass the telephone system and offer Internet access hundreds of times faster than twisted-pair hard-wired connections or cell-phone modems.

Some of the most important assets of fixed wireless are as follows.

• Subscribers can be added or moved (to a certain extent) without modifying the infrastructure.
• Subscribers in remote areas can be brought into a network without the need for stringing new cables or optical fibers across the countryside.
• Broad bandwidth is possible because there are no wires or cables to introduce reactance into the connection (reactance limits bandwidth by preventing signals higher than a certain frequency from efficiently propagating).
• As the number of subscribers increases, the connection cost per subscriber goes down.
