Example 2
1st Fresnel radius, middle of a 10 km, 24 GHz link
With all other variables equal except for lambda, we see that the Fresnel zone radius can vary greatly based on the
frequency. While choosing a higher frequency to achieve a smaller Fresnel zone may sound appealing to avoid
obstructions, there are tradeoffs: tougher aiming and higher rain fade.
Fresnel Zone Calculation Shortcuts
Who doesn't like a shortcut? If you only care about the maximum radius, the following equations can be used
instead:
Metric System US Customary units
where,
r = radius (meters)
D = total distance (km)
f = frequency (GHz)
where,
r = radius (feet)
D = total distance (miles)
f = frequency (GHz)
