The simultaneous charging of multiple mobile devices at 0.5 meter away from the power source is now possible under the international electromagnetic field guidelines IMAGE: This is a demonstration of the omnidirectional wireless-charging system technology that allows mobile devices to be charged at any location and in any direction, even if the devices are away from the power source, just as Wi-Fi works for Internet connections. With this technology, so long as mobile users stay in a designated area where the charging is available, e.g., the Wi-Power zone, the device, without being tethered to a charger, will pick up power automatically, as needed.
