We use fixed RFID readers and antennas in our toll booths. Sometime, booth one's antenna reads booth two's vehicle tags. Can you please suggest a solution to this problem?
You could change the angle of the reader antenna to point down more, which might solve the problem. You might also be able to attenuate each antenna so that it would be strong enough to read tags on cars in a specific lane, but not powerful enough to read those in the adjacent lanes. If those options don't work, you would need to put shielding between the lanes to prevent the signal from reaching the tags in the other lanes. There are several companies, such as MWT Materials, that sell curtains for blocking RF signals.
