Description
Summary:Recent advances in wireless data communications technology create new possibilities for connecting more than 2 RS-232 ports or other low-speed serial connections and supporting point-to-multipoint configurations. This low-speed wireless networking can be used to increase productivity, improve customer service, and reduce costs for a wide range of applications. Spread-spectrum radio is key to the application of wireless in the network topology. Instead of using a single, modulated carrier frequency, spread-spectrum uses one of 2 techniques: frequency hopping or direct-sequence. Beyond an immunity to noise and interference, spread-spectrum offers another key advantage: it can be used in much of the world without a license from a regulatory body. Three case studies of the use of outdoor spread-spectrum radio are presented.
