And now... some math. The Fresnel zone radius can be calculated along any point of the link using the following
equation:
where,
F
n
= The nth Fresnel Zone radius in meters
d
1
= The distance of P from one end in meters
d
2
= The distance of P from the other end in meters
λ = The wavelength of the transmitted signal in meters
Tip: Convert Frequency to Wavelength
Tip: Convert Frequency to Wavelength
Lambda "λ" is calculated by dividing the speed of light (c) by the desired frequency (f) in Hz.
Lambda "λ" is calculated by dividing the speed of light (c) by the desired frequency (f) in Hz.
For 5 GHz, lambda is 299,792,458 meters per second / 5,000,000,000 Hertz = 0.05996 meters
For 5 GHz, lambda is 299,792,458 meters per second / 5,000,000,000 Hertz = 0.05996 meters
Application Example
Example 1
1st Fresnel radius, middle of a 10 km, 5 GHz link
