In summary, the WPC – Qi Standard provides a level of functionality beyond the low-efficiency, low-power approach. It is a industry wide standard for wireless power up to 5 W. It is aimed to enable interoperability between various charging pads and portable devices. Additionally, the Qi Standard allows for power to be transmitted through a shared magnetic field, shielded below the transmit coil and above the receive coil, power is only transferred when needed and at the required level. Finally, Texas Instruments offers development kits to explore and develop with this technology.
