[…] happens when a material causes a signal to scatter in all directions.
Scattering
[…] happens when a signal bounces off of a material, for example metal.
Reflection
[…] happens when a wave encounters an obstacle and travels around it.
Diffraction
[…] happens when a wave is bent when entering a medium where the signal travels at a different speed.
Refraction
[…] happens when a wireless signal passes through a material and is converted into heat, weakening the original signal.
Absorption
[…] is aka Wi-Fi 4.
802.11n
[…] is aka Wi-Fi 5.
802.11ac
[…] is aka Wi-Fi 6.
802.11ax
[…] is the maximum strength of the electric and magnetic fields of a wave.
