The LANCOM Antenna Distance Calculator is a program that you can use for calculating the output power at the AP and to make a first estimate of the achievable ranges and data rates.
After selecting your components (APs, antennas, lightning protection and cable) the calculator works out the data rates, ranges, and the antenna gain settings that have to be entered into the AP.
Important: Please note that when using 5 GHz antennas additional technologies such as dynamic frequency selection (DFS) may
be stipulated depending on the country of use. The operator of the wireless LAN system is responsible for ensuring that local
regulations are met.
