4.3.5 Reciprocal influence of read points
Antenna alignment and resulting antenna spacing
The minimum distance required between antennas that use the same frequency and that are
connected to different readers depends on the maximum transmit power set and the antenna
alignment. The following minimum distances apply with maximum transmit power.
A Back to back
B Pointing at each other
C Next to each other
