What is frequency hopping?
A. Frequency hopping is a technique used to improve performance of the RFID system and to allow multiple readers or other RF devices to work in the same area without interfering with one another. Frequency-hopping readers operate briefly at a particular frequency and then “hop” to another frequency within that ISM band. The 915MHz band actually runs from 902MHz to 928MHz. Thus, there are a lot of different frequencies to hop to when many readers are in the same area.
