What is wireless communication?
• wireless communication is basically transmitting and
receiving voice and data using electromagnetic waves in
open space. They are basically free from wires.
• Electromagnetic waves
• Travel at speed of light (c = 3x108 m/s)
• Has a frequency (f) and wavelength (l)
» c = f x l
• Higher frequency means higher energy photons
• The higher the energy photon the more penetrating
is the radiation
