Range of an IEEE 802.11b/g system in industrial environments based on site survey measurements and propagation models

In this paper, the wireless range of an 802.11b/g site survey measurement system in an industrial environment is investigated. A measurement procedure for executing site surveys has been developed. The range resulting from the site survey measurements has been compared to an existing industrial propagation model through calculation of a link budget, and generally good agreement is obtained. Deviations between site survey range and link budget range are attributed to attenuation by large obstacles.
