5.2. Indoor Radio Environment
As shown by Maxwell's equation, radio waves travel at the speed of light which has been measured at 186,281.7 miles/second or, equivalently, 299,792.8 kilometers/second in open space. For optimal performance, the dimensions of radio transceiver antenna depend on the radio wavelength. In the normal condition the wavelength is obtained by dividing the speed of light by the frequency of the radio wave as in
Equation 5.1
where c is the speed of light and f is the frequency of the radio wave. These wavelengths are between 0.32 and 0.33 m, 0.12 and 0.125 m, and 0.051 and 0.053 m for the 902–928 MHz, 2.4–2.4835 GHz, and ...
