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.
