Selection of antennas using the LANCOM Antenna Calculator
You can use the LANCOM Antenna Calculator to calculate the output power
of the access points as well as for a first estimation of the achievable distances
and data rates. The program can be downloaded from our Web site at
www.lancom.eu.
After selecting your components (access points, antennas, lightning protec-
tion and cable) the calculator works out the data rates, ranges, and the
antenna gain settings that have to be entered into the access point.
