The first season focused on the major Radio Frequency (a.k.a. RF) properties. Since both Wi-Fi and light are made of electromagnetic waves, the idea was to use light to have a visual idea of what these RF properties are and how they can affect our Wi-Fi networks.
Episode #1 - PropagationPropagation is the idea that a radio frequency electromagnetic wave is losing energy as it travels away from its source. Read the full article |
Episode #2 - ReflectionRadio frequency reflection occurs when the electromagnetic wave encounters a flat surface and is reflected with a loss of energy. Read the full article |
Episode #3 - RefractionRefraction occurs when a radio wave is moving to a medium having a different density. Read the full article |
Episode #4 - DiffractionRadio 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. Read the full article |
Episode #5 - ScatteringScattering happens when the diffusion of the signal is reflected in multiples directions when hitting an uneven surface. Read the full article |
Episode #6 - AbsorptionAbsorption is the fact that a radio wave loses some of its energy going through a medium or an obstacle. Read the full article |
Happy new year 2015!
