Antenna distance
Consider the Fresnel zone, which is an ellipsoid shaped area
between wireless devices. XIRIUM PRO TX and RX units should
be free of any obstacles within the Fresnel Zone. Maintaining
proper antenna height becomes essential to ensure trou-
ble-free communication between XIRIUM PRO devices.
To define an area that is free of obstacles, use the following
chart to estimate proper antenna height.
