Abstract:
This specification discloses methods and systems providing reader-mode performance enhancement for operating a device that communicates via inductive coupling. In reader-mode, Tx (transmitter) power of a reader device is maximized even though for some tags, the communication distance is limited by Rx (receiver) sensitivity. Therefore, power is wasted. Even worse, a too highly boosted Tx power demands a high Rx dynamic range and consequently a low Rx sensitivity. In turn, the communication distance may even be degraded by a too highly boosted Tx power. Therefore, in some embodiments, reader-mode performance enhancement is based on backing off Tx (transmitter) power when not needed (energy distance>communication distance) to save power and/or to relax reader-mode Rx (receiver) sensitivity requirements. In some embodiments, the backing off of Tx (transmitter) is also based on a sensor determining a geometric position/location of a reader device relative to a tag-mode device.

Claim (Index 14):
A reader device that communicates via inductive coupling, the device comprising:\n a transmitter unit, the transmitter unit configured to generate a transmitted field; a receiver unit, the receiver unit configured to receive a response from a tag device, wherein the tag device responds using load modulation on the transmitted field; a sensing unit, the sensing unit configured to detect the response from the tag device,\n wherein detecting the response from the tag device indicates that the response can be demodulated, \n wherein the sensing unit is further configured to determine a signal quality information associated with the response from the tag device; \n a transmitter control unit, the transmitter control unit configured to control a strength of the transmitted field based on the signal quality information.
