The Fresnel Zone formula shown below is based on a flat earth. In other words, it does not take
the curvature of the earth into consideration. The effect of this is to budge the earth in the
middle of the link. However, for relatively short distances, the effect of the earth’s curvature
and the specific topography of the terrain are negligible.
Table 2-1 shows the calculated minimum path clearance required for operation of a pt-to-pt
millimeter wave operating in the 60 GHz band based on the Fresnel Zone formula shown below.

Can emissions, blowing or swaying trees, or other obstacles in the line of sight interrupt the
connection?
Is there a possibility of work activity or people passing in front of the transmission that could
interfere with the clear line of sight
Evaluate environmental mounting conditions
Only mount the radio transmission equipment to a stable and vibration-free mounting platform
– this is a critical factor to successful performance.
