Abstract
Systems and methods to determine motion parameters of physical objects using radio frequency identification (RFID) tags attached to the objects. In one embodiment, a method implemented in a radio frequency identification (RFID) system includes determining a motion parameter of the RFID tag based on detecting a Doppler frequency shift in a radio frequency signal received from the RFID tag.
Claims22
An apparatus, comprising:
- a modulator configured to generate a first signal according to first data;
- a transceiver coupled to the modulator to transmit the first data via first radio frequency signals;
- a circuit coupled to the transceiver to generate a second signal based on second radio frequency signals;
- and
- a controller configured to determine:
- an identity of a device based on second data received in the transceiver and a frequency of the second signal.

A method, comprising:
- generating, by a modulator of an apparatus, a first signal according to first data;
- transmitting, by a transceiver coupled to the modulator in the apparatus, the first data via first radio frequency signals;
- generating, by a circuit coupled to the transceiver in the apparatus, a second signal based on second radio frequency signals;
- and
- determining
- an identity of a device based on second data received in the transceiver and a frequency of the second signal.
