The Fresnel Zone is important to the wireless link as it defines an area around the LoS that can 

introduce RF signal interference if blocked. Objects in the Fresnel Zone such as trees and 

buildings can diffract or reflect the main signal away from the receiver, changing the RF LoS. 

 

The integrated antenna radiates and receives polarized radio signals. For the link to operate 

correctly, two antennas at each end of the link must always be set for the same polarization, 

either vertical or horizontal.
