the way the system works:
The system uses a transmitting antenna, a series of relays and a receiving rectenna (a rectifying antenna capable of converting microwave energy into electricity). Each of these components appear in these images to simply look like big ol' squares on poles. Its beams use the non-ionizing Industrial, Scientific and Medical band of the radio spectrum, including frequencies commonly used in Wi-Fi and Bluetooth.
good technology. very efficient and simple ..
