SYNOPSIS use Math::FresnelZone; use Math::FresnelZone qw(fresnel fresnelMi fresnelKm); The arguments are: 0 - distance in kilometers or miles (default is 1), 1 - frequency in GHz (defualt 2.4), 2 - set to true to specify that the distance you are inputting is in miles and that the results should be in in feet (default is 0 - IE kilometers/meters) fresnel() my \$fresnel_zone_radius_in_meters = fresnel(); # fresnel zone radius in meters for 1 kilometer at 2.4 GHz my \$fzr_in_meters = fresnel(5); # fresnel zone radius in meters for 5 kilometers at 2.4 GHz my \$fzr_in_meters = fresnel(5,4.8); # fresnel zone radius in meters for 5 kilometers at 4.8 GHz my \$fzr_in_feet = fresnel(3,9.6,1); # fresnel zone in feet for 3 miles at 9.6 GHz If you are inputting Kilometers the result is in meters (these 3 calls have identical results): fresnel(\$Km,\$GHz); fresnelKm(\$Km,\$GHz); # see documentaion below for info about fresnelKm() fresnel(\$Km,\$GHz,0); If you are inputting Miles (by specifying a true value as the 3rd argument) the result is in feet (these 2 calls have identical results) fresnel(\$Mi,\$GHz,1); fresnelMi(\$Mi,\$GHz); # see documentaion below for info about fresnelMi() fresnelKm() You can use this to make it easier to avoid ambiguity if are working in kilometers/meters. It takes the first two arguments only: distance in kilometers and frequency in GigaHertz my \$fzr_in_meters = fresnelKm(\$Km,\$GHz); fresnelMi() You can use this to make it easier to avoid ambiguity if are working in miles/feet. It takes the first two arguments only: distance in miles and frequency in GigaHertz my \$fzr_in_feet = fresnelMi(\$Mi,\$GHz);.
