Abstract:
1. A communications device comprising: a transceiver; a power supply capable of selectively operating in one of a pulse width modulation (PWM) supply mode and a pulse frequency modulation (PFM) supply mode, and electronically coupled to the transceiver to supply power to the transceiver according to an active supply mode of operation; and a controller coupled to the power supply and to the transceiver and which determines a quality level of a signal that is processed by the transceiver, the controller further triggers the power supply to operate exclusively in the PWM supply mode when the quality level of the signal is below a threshold performance level, else the power supply autonomously switches between the PWM supply mode and the PFM supply mode if the controller does not trigger the power supply to operate in a specific supply mode, wherein the controller: dynamically determines a level of power supply demand associated with dynamically changing device operations, and in response to determining that the level of power supply demand exceeds a threshold power supply level, triggers the power supply to operate exclusively in the PWM supply mode.
