frequency hopping
A technique used to prevent readers from interfering with one another.

In the United States, UHF RFID readers actually operate between 902 and 928 MHz, even though it is said that they operate at 915 MHz.

The readers may jump randomly or in a programmed sequence to any frequency between 902 MHz and 928 MHz.

If the band is wide enough, the chances of two readers operating at exactly the same frequency is small.

The UHF bands in Europe and Japan are much smaller so this technique is not effective for preventing reader interference.
