DISTRIBUTED ANTENNA SYSTEM USING POWER-OVER-ETHERNET
First Claim
1. A system, comprising:
- power sourcing equipment configured for providing power to a powered device via a channel; and
a sub-system configured for determining, based on a resistance of the channel, an amount by which to increase a level of power provided to the powered device,wherein the power sourcing equipment is configured to adjust the level of power by the amount in response to a command from the sub-system.

Abstract
A system is provided for adjusting power provided to a device. The system can include power sourcing equipment and a sub-system. The power sourcing equipment can provide power to a powered device via a channel. The sub-system can determine an amount by which to increase the power based on a resistance of the channel. The power sourcing equipment or the powered device can adjust the power (or load) responsive to a command from the sub-system. The sub-system can include a measurement device and a processor. The measurement device can measure an output voltage of the power sourcing equipment, an input voltage of the powered device, and a current on the channel. The processor can determine the resistance of the channel based on the output voltage, the input voltage, and the current. The processor can output a command specifying an increase or decrease in power supplied by the power sourcing equipment.
