An auto ID reader and one or two radio frequency transceivers are supported on
a common support having a predetermined form factor, such as that of a scan engine
module commonly utilized in hand-held bar code symbol scanners. Common digital
processing circuitry is used for processing the signal from the auto ID sensor
and an RF transceiver baseband signal, making a highly integrated and compact arrangement.
A single Fast Fourier Transform circuit is utilized for each transceiver.
