The demo TV has a receiving coil on its back panel (production models would include the loop inside) while the transmitting system is placed flat underneath the TV at a distance of 20 inches. The company says the transmitting system could be also integrated into a wall or an AV unit.

The company says you'll be able to move the TV around without fear of misalignment and that the system is 80 to 90% more cost-efficient than other existing wireless solutions. The technology is patented and ready to go, and it could also be used in larger devices such as e-vehicles, drones, robots or wearable devices.
