Math and physics for the 802.11 wireless LAN engineer

Bardwell J.

This is a highly technical (but very readable) paper detailing the principles of electromagnetism and RF signal propagation. The paper includes an overview of Maxwell’s wave equations and a derivation of the Fresnel Zone formulae from a Pythagorean representation of out-of-phase multipath signal waveforms. The paper is intended for RF communication engineers and experienced WLAN designers who seek to understand the underlying physics behind 802.11 wireless network.
