Abstract

A radio frequency identification interrogator comprises a transmitter (27, 28, 29) and a receiver (32). The transmitter transmits an interrogation signal and the receiver receives a backscattered signal from one or more tags. The transmitter includes a modulator (28) which further modulates signalling information from a signalling channel onto a continuous wave signal (27). The modulated signalling channel signals are orthogonal to reader to tag and tag to reader data transmissions.
