After initial start the WMI tries to detect if an object was placed on the surface. When the device detection was successful, the system switch to Qi-detection-mode. If the Qi-detection-mode has found a mobile (acc. Qi-standard) then charging process will start. The WMI was designed following the Qi standard to charge mobiles prepared for Qi-charging. Because the WMI2 does not fulfill the whole Qi-standard, therefore no Qi Logo is placed on the WMI and no Qi-certification has been processed. If you remove the mobile during charging from the WMI, charging process is stopped immediately. The Wireless Mobile Interface (WMI) enables the user to wirelessly charge a mobile device (ME) supporting the device in WLC equal standard. Additional key features of WMI include: Support of NFC telematics functions including NFC vCards Diagram of internal NFC antenna, relevant measurements in blue
