Please browse and make use of these materials. Each title is one training unit—the total sum of materials for one single class, session or lecture. One unit may be one video of a two-hour lecture. Another may be several files including class handouts, presentation slides, trainer’s notes, and homework.
Members can add their own tags and comments to any unit. Your input and data is greatly appreciated! Success stories and suggestions will help us build this community to better serve you, our future trainers and students.
This lecture introduces some basic concepts related to modern computer networking: reasons to build a computer network, standardisation, OSI model, network layers in theory and practice, classification and topology of networks, media and hardware (ethernet), IP addressing, subnetting, DNS, basic network configuration of a PC.

|WirelessU Concept Paper||
A single 3-page paper with all the important WirelessU concepts. Mostly just copied from the web pages, for those that want a document rather than a pointer to the web site.

|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.

|Introduction to Radiowaves and Basic RF Measurements||
This very short lecture consists of two parts: the first part (15 minutes) is a basic introduction to radiowaves and RF signals, with definitions and terminology (frequency, wavelength, phase, amplitude, power, interference, modulation).

|A long-distance link in Malawi||
A case study of the 2008 ICTP / Blantyre Polytechnic / Blantyre College of Medicine joint project to build a long distance WiFi network. The network connects Blantyre to Mangochi, spanning a distance of about 160 km.
Given at AfNOG 2009 (Cairo).

|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).

|Unidad 21: Mapeo de Alcance||
Se presenta una metodología para el Planeamiento, Seguimiento y Evaluación de Proyectos, que hace particular énfasis en factores humanos y otros aspectos a los que frecuentemente no se les presta la debida atención.

|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).
