Abstract:
A method for operating a sensor includes receiving identification information from one or more electronic identification devices (EIDs) located in a vicinity of the sensor. A number of EIDs located in the vicinity of the sensor is determined based on the received identification information. A determination is made if the number of EIDs located in the vicinity of the sensor exceeds a first predefined threshold. Transmission power to the sensor is selectively adjusted based on the number of EIDs with respect to the first predefined threshold, in response to determining that the number of EIDs located in the vicinity of the sensor exceeds or is less than any number of predefined thresholds.
