|Intro to RF and dB math||
Slideshow presented at AfNOG 2009 in Cairo, Egypt.
It is a very quick introduction to the physical basis of telecommunications, many concepts are briefly introduced, like i.e.: e.m. waves (amplitude, frequency, ...), RF signals (power, modulation, ...), power measurement, spectrum analysis, dB (math, examples, Alexander Bell).

|Radio Propagation and Link Budget||
This slideshow was presented at AfNOG 2009, in Cairo (Egypt).
It is a brief introduction to radiopropagation (behavior of radiowaves, effects of the environment, line of sight, Fresnel zone) and to link budget calculation (link planning, power budget, sensitivity and gain, losses, software tools).
It is provided in both Adobe PDF format and Apple Keynote original source.

|Basic antenna theory||
This slideshow was presented at AfNOG 2009 in cairo, Egypt.
It is a very brief introduction to antennas for WiFi, touching concepts like directivity and gain. It mentions radiation patterns and other properties of antennas as well. A few examples of typical antennas for WiFi are also given (omni, cantenna, parabolic dish).
