 IPICO’s Dual Frequency RFID Technology uses the same IP-X multi-read protocol as its UHF products, but the low frequencies used (125kHz power-up and 6.8MHz return signal) can penetrate through "lossy" media without the tag antenna detuning, and the high attenuation encountered with UHF systems. Because of the high tag transmit carrier frequency, high data rates are achievable (up to 128kbit/sec), resulting in fast reading of multiple tags in the beam. Dual Frequency technology allows for longer ranges to be achieved than single frequency low frequency technologies, e.g. 125 kHz or 13.56 MHz. This is because the tag data carrier frequency (6.8 MHz) is much higher than the power-up frequency (125 kHz). Because of these unique features and the robust multi-read anti-collision properties of the IP-X protocol, Dual Frequency technology lends itself ideally to "Free-Flow" people tracking, which means that the tag does not need to be specially presented to the reader. Sport Time-Keeping is just one application. Others are access control and attendance monitoring (e.g., at conferences).
