This chart lists the radius of an ellipsoid for specific distances 
between TX and RX antennas:

distance d 

50 m 100 m 300 m           500 m  

radius r 

0,87 m 1,22 m 2,12 m           2,74 m

Any wireless RF system design employing XIRIUM PRO should 
consider the height of the antennas and the distance between 
devices. For a setup with a single transmitter and a number of 
receivers the minimum distance between the TX and any RX 
should be 10 meter*.

* For shorter distances enter Advanced Mode tin the Xirium PRO app to enable 
the RF attenuator on the RX.

When these factors are properly addressed, consistent links 
can be established.
