Patent ID: 10976791

Abstract:
An access point, which is a Power over Ethernet (PoE) Powered Device (PD) measures input voltage and input current. The access point determines a power requirement of the access point based on the measured current, measured voltage, and information about power requirements of access point components or devices coupled to the access point a power requirement of the access point. The access point communicates the determined power request to a power sourcing equipment (PSE), e.g., a network switch. In some embodiments, the access point further communicates one of: measured input current and measured input voltage to the PSE. The PSE uses the information received from the access point, e.g., power request and power measurements to determine an amount of power to be granted to the access point. If the access point does not receive the requested power level the access point selects internal components and/or external devices to de-power.
