Make sure that line of sight is provided when planning the device placement for a point-to-point link in order to achieve maximum range and performance between two devices. Perform a survey to identify all the obstructions (such as trees or buildings) in the path and to assess the risk of interference. Please note, any obstacle in the propagation path is critical for 70 GHz frequency band, make sure the line of sight is 100% clear.
Below is an incomplete list of possible obstructions along the signal propagation path:

Wireless device installation
...
- Keep 100% clear line of sight between devices. In case of installations over vegetation and forest, make sure the direct line of sight stays above the trees; in urban environments - above the tallest buildings along the radio path.
- Install wireless devices as far as possible from other radio devices (the recommended distance is at least 2 meters).
- Reflecting surfaces should be considered (buildings with reflective windows, water surfaces or wet grounds). These can also decrease the signal quality when encountered along a clear line of sight link, because of fading caused by multipath propagation.
- When installing wireless devices over the water, tune the height bracket within a 1-3 meters range variation, because it can yield significant signal level variations due to multipath fading70 GHz antenna has a very narrow beam, keep devices directed strictly to each other.
