Summary

This module covered the mathematics and physics necessary for understanding how WLANs operate. Although it is not usually necessary to perform complex calculations to install a WLAN, an understanding of the underlying principles makes it easier to account for the many factors that can interfere with the proper operation of the WLAN.

When performing a site survey for a new or existing WLAN, be sure to take into account factors such as refraction, reflection, and multipath distortion that were discussed in this module.
