When two or more readers are working at the same time, in order to prevent adjacent readers from interfering with each other, the readers must meet the following two requirements when installing and debugging:
1) The center distance between the antennas of two adjacent readers is greater than 3 meters;
2) The working frequencies of two adjacent readers are set to 920MHz-925MHz frequency hopping, and the frequency hopping interval is recommended to be 1MHz.
