Energous uses radio frequency radio to do wireless

As the first speaker of the concept of wireless charging, Edison's dead rival, Tesla (really not a big-screen sedan run, is a scientist Nikola) had conceived a signal tower to provide radio power to the city's citizens. Most of the wireless charging solutions so far have been connected by coils and paired charge plates to obtain electricity, and the distance between the two is greatly limited. However, the Bay Area company energous another option: using radio frequency waves to provide point-to-point radio power to equipment within 4.5 meters.

energous WattUp Scheme distribution transmitter and receiver at both ends, the transmitter can be placed in the room high or corner, when the device connected with the receiver into its range of transmission will gather radio frequency waves for the device charging. The receiver locates the device location and connects to the transmitter via Wi-Fi and low-power Bluetooth (Bluetooth LE). Compared with the traditional single high power antenna transmission scheme, energous WattUp uses multiple antenna design to achieve strong signal transceiver.

A transmitter can provide 2 watts of power (a single device theory up to 10 watts) for four charging devices at a distance of 4.5 meters, while taking only half of the traditional wiring charge (excluding the fast charging technology).
