Distributed antenna system using power-over-ethernet
First Claim
1. A system comprising:
- a powered device configured for receiving power from a power source device via a channel, the powered device comprising a base load and one or more optional loads; and
a sub-system configured for;
determining the power capabilities of the channel,determining a respective power requirement for each of the one or more optional loads, andbased on the power capabilities of the channel and the respective power requirements for the one or more optional loads, configuring the powered device to operate the base load and all or a subset of the one or more optional loads.

Abstract
A system is provided for adjusting power provided over a channel 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) in response to a command from the sub-system. The sub-system can include at least one 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 the level of power supplied by the power sourcing equipment.
