OPERATIONAL PARAMETERS BASED ON PROXIMITY
First Claim
1. A method for controlling an interrogation rate of a radio-frequency identification (RFID) reader based on proximity of the RFID reader to an RFID tag circuit, the method comprising:
- moving the RFID reader from a first location to a second location, wherein at the first location the RFID tag circuit is outside an interrogation range of the RFID reader, and at the second location the RFID tag circuit is within the interrogation range of the RFID reader;
at the first location;
transmitting interrogation signals from the RFID reader at a first interrogation rate;
at the second location;
transmitting the interrogation signals from the RFID reader at the first interrogation rate;
receiving response signals at the RFID reader, the response signals transmitted from the RFID tag circuit in response to receiving the interrogation signals from the RFID reader, the response signals conveying a control parameter to the RFID reader that indicates to the RFID reader to transmit the interrogation signals at a second interrogation rate different from the first interrogation rate; and
thereaftertransmitting the interrogation signals from the RFID reader at the second interrogation rate.

Abstract
A method is disclosed for controlling operational parameters of a wireless reader device and/or one or more other devices based on proximity of the wireless reader device to a wireless electronic circuit. At a first location, the wireless reader device and/or the one or more other devices are controlled based on a first operational parameter. At a second location, interrogation signals are transmitted from the wireless reader device, and response signals are received at the wireless reader device. The response signals are transmitted from the wireless electronic circuit in response to receiving the interrogation signals from the wireless reader device. The response signals convey a control parameter to the wireless reader device that is associated with a second operational parameter. Thereafter, the wireless reader device and/or the one or more other devices are controlled based on the second operational parameter.
