Although I know that far-field RF Exposure measurements have been done for this product, I was wondering if there have been any near-field measurements or certifications performed on this device? I am specifically interested in the power density levels from the Tx antenna(s) at a distance of a few millimeters. This type of information would be important to assess safety in the case where the device is operated in close proximity to the user. I would appreciate any information you can provide.
