Abstract
In one embodiment, there is provided a power interchange system for distributing direct current (DC) electrical power. The power interchange system comprises a plurality of nodes comprising a first node and a second node. The first node comprises a first communication device and a first power source to power the first communication device. The second node comprises a second communication device and a second power source to power the second communication device. The power interchange system further comprises a wired cable connecting the first node and the second node. The wired cable comprises at least one first wire to convey DC power from the first power source of the first node to the second node to power the second communication device or from the second power source of the second node to the first node to power the first communication device.
