3.2.3 Crosstalk between readers in the application system
When multiple RFID readers are working in the application system at the same
time, the unreasonable installation method will result in the risk of the tag being
read by other readers.For example, the installation direction between the reader
antennas is not standardized, and the distance between adjacent readers is too
close.
To avoid crosstalk, adjacent readers operating in the same frequency band should
maintain a minimum safe distance.This distance mainly depends on the
maximum effective radiated power (ERP) of the reader and the directional
relationship between the reader antennas.
