Mitigating Adjacent RFID Reader Interference |
| 摘要 |
A radio frequency identification (RFID) automatic vehicle identification (AVI) system configured to mitigate signal interference, the system comprising a plurality of RFID readers, comprising a first RFID reader and a second RFID reader; and a plurality of antennas, wherein a first antenna is connected to the first RFID reader and a second antenna is connected to the second RFID reader. Prior to the first RFID reader transmitting a signal through the first antenna, the first RFID reader samples a received radio frequency (RF) signal from the first antenna, and if the received RF signal meets predetermined strength and frequency criteria, the first RFID reader inhibits transmission of the signal through the first antenna. |
