Power scheduling for short-range wireless tags
First Claim
1. A reader device for short-range wireless tags comprising:
- one or more RF antennas;
a sensing module coupled to the RF antennas and arranged to selectively activate and deactivate one or more of the RF antennas and to read data from a plurality of objects comprising short-range wireless tags which are proximate to an active RF antenna; and
a scheduler module arranged to obtain device characteristics for the plurality of objects based at least in part on data read by the sensing module and to generate a powering schedule for the plurality of objects based at least in part on the device characteristics, the device characteristics including at least one of power usage data for the plurality of objects or an indication of an amount of data to be communicated to the reader device from the plurality of objects,and wherein the sensing module is further arranged to implement the powering schedule generated by the scheduler module.

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.
