Make Wi-Fi Visible – Season 1 Recap
As 2014 is ending today, this makes it the perfect day to do a recap of the first season of Make Wi-Fi Visible. This series of articles is aimed to explain Wi-Fi concepts using the light analogy.
EPISODE #1 - PROPAGATION
Propagation is the idea that a radio frequency electromagnetic wave is losing energy as it travels away from its source.
EPISODE #2 - REFLECTION
Radio frequency reflection occurs when the electromagnetic wave encounters a flat surface and is reflected with a loss of energy.
EPISODE #3 - REFRACTION
Refraction occurs when a radio wave is moving to a medium having a different density.
EPISODE #4 - DIFFRACTION
Radio waves tend to bend around sharp objects creating a new wave front. This phenomena is called diffraction. This allows the waves to go around an object and still reach a receiver.
EPISODE #5 - SCATTERING
Scattering happens when the diffusion of the signal is reflected in multiples directions when hitting an uneven surface.
EPISODE #6 - ABSORPTION
Absorption is the fact that a radio wave loses some of its energy going through a medium or an obstacle.
As of today, I am happy to announce that season #2 of Make Wi-Fi Visible will be released in 2015! This second series of articles will focus on antennas.
Happy new year 2015!
Bonne année à tous!
