Abstract
A dual mode interrogation is carried out by sending narrow band radio frequency interrogation (RFID) signal for narrow band RFID communication units, the narrow band signal comprising substantially continuous periods, and by sending a high data rate RFID interrogation signal during the substantially continuous periods of the narrow band RFID signal so that two different types of RFID communication units are interrogated substantially simultaneously.
