Hello,
Its common to use some kind of shield around the device to reduce the emissions.

Hello,
If you have used a shield around the PCB it should have reduced the emissions. Have you isolated that the emissions are indeed coming from the device and its not some WiFi or Bluetooth activity in the vicinity?
