This page provides a Fresnel Zone Radius Calculator for determining the optimal Fresnel zone, crucial for achieving peak performance in wireless links between two Line-of-Sight (LOS) antennas. It offers two calculators based on different equations for calculating the Fresnel zone radius.
Fresnel Zone Radius Calculator (Equation 1)
This calculator uses the first equation to determine the Fresnel zone radius.
EXAMPLE #1:
- INPUTs:
- Distance = 10 km
- Frequency = 2.4 GHz
- OUTPUTs:
- Fresnel Zone Radius = 17.67 meters
- 80% of Fresnel Zone Radius = 14.14 meters
Fresnel Zone Radius Calculator (Equation 2)
This calculator uses the second equation to determine the Fresnel zone radius.
EXAMPLE #2:
- INPUTs:
- Distance = 100 miles
- Frequency = 2.4 GHz
- OUTPUTs:
- Fresnel Zone Radius = 232.54 feet
- 80% of Fresnel Zone Radius = 186.03 feet
Fresnel Zone Radius Calculator Equation
The following equation is used to calculate the Fresnel Zone Radius. The calculators above are based on these two equations:
