Abstract:
Systems and methods for managing power consumption of a transceiver, e.g., Bluetooth, are provided. A representative transceiver includes an antenna that receives analog radio frequency (RF) signals, and a RF analog circuitry that receives and processes the analog RF signals from the antenna. An analog-to-digital converter (ADC) receives and converts the processed analog RF signals to digital RF signals. A digital circuitry includes a RF power detector that receives the digital RF signals and determines a RF power of the analog RF signals from the antenna based on the digital RF signals. A computing device instructs the RF analog circuitry to operate in low current drain RF receiver mode during page scanning and/or inquiry scanning. The computing device is designed to receive the RF power of the received analog RF signals and manages the power consumption of the transceiver based on the RF power.
