DISTRIBUTED ANTENNA SYSTEM USING POWER-OVER-ETHERNET
摘要
<p>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 (302). The sub-system can determine an amount by which to increase the power based on a resistance of the channel (306). 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 (304). The processor can determine the resistance of the channel based on the output voltage, the input voltage, and the current (306). The processor can output a command specifying an increase or decrease in the level of power supplied by the power sourcing equipment.</p>
