Long Range RFID Scanner for Warehouse Gates: How to Reduce Misreads
A long range RFID scanner can identify tags across a warehouse gate, but simply increasing reading power is not the best way to improve performance. A reliable RFID gate needs the right antenna direction, reader settings, tag placement, physical layout, and software filtering to create a controlled reading zone. There is a moment in almost every RFID gate project when someone asks: “Why is the reader picking up the pallet next to the gate?” The reader may be working perfectly. That is what makes the problem confusing. A long range RFID scanner is designed to detect tags from a distance. If the reading area is not controlled properly, the reader can do exactly what it was designed to do — detect tags that happen to be within its RF field. The problem is not always weak performance. Sometimes there is simply too much reading range in the wrong direction . This becomes especially noticeable in warehouses where several pallets are waiting close to the entrance.
