Abstract
A reader device for short-range wireless tags comprises a sensing module coupled to one or more RF antennas. The sensing module is arranged to selectively activate and deactivate individual RF antennas and to read data from a plurality of objects comprising short-range wireless tags which are proximate to an active RF antenna. A scheduler module within the reader device is arranged to obtain device characteristics for the plurality of objects based at least in part on data read by the sensing module and then to generate a powering schedule for the plurality of objects based on the device characteristics. The generated powering schedule is then implemented by the sensing module.
