Abstract:
This paper was written in an effort to demonstrate the applicability of professional microwave engineering techniques to consumer wireless networks using unregulated spectrum by documenting the design and implementation of a 7-kilometer 802.11b bridge. The wireless revolution is in full force. The 802.11b standard adapted in 1999 created the first wireless standard to break through the important 10 mbps barrier. Shortly after adoption, inexpensive consumer wireless devices became widely available. At first, these were used for the predicted purpose of creating a local network at home. Later people discovered that using directional antennas allowed these devices to communicate over long distances. In a quest to spread the broadband revolution, some users started building point-to-point links several miles long. Many of these links were built using trial-and-error. However, the science of engineering microwave networks is not new. Professionals have been designing long distance links using regulated microwave frequencies for years. With improved scientific knowledge of microwave engineering, individuals will be able to create even more amazing wireless feats.
