Power over WiFi
Formal
A technology that can convert the signals sent by wireless routers into DC (direct current). WiFi hotspots and routers are programmed under PoWiFi to broadcast noise when a channel is not being used to send data, thus providing a continuous stream of low-power signals that can be harvested.
Practical
WiFi hotspots and routers are programmed under PoWiFi to broadcast noise when a channel is not being used to send data, thus providing a continuous stream of low-power signals that can be harvested. WiFi generally transmits up to 1 watt of power to carry data.
