All clear after reading the “Intel 2012 white paper” about USB 3.0 RF interference in 2.4 GHz wireless devices.
“The noise generated due to the USB 3.0 data spectrum can have an impact on radio receivers whose antenna is placed close to a USB 3.0 device and/or USB 3.0 connector. The noise is a broadband noise that cannot be filtered out, since it falls within the band of operation of the wireless device (2.4–2.5 GHz). The noise degrades the signal-to-noise ratio that the wireless receiver sees and limits its sensitivity. This then reduces the operating wireless range of the device.
Improving the shielding on the USB 3.0 receptacle connector can help reduce the amount of noise radiated due to USB 3.0 signaling. In addition, shielding of the USB 3.0 peripheral device plays an important role in reducing the amount of noise radiated in the 2.4–2.5 GHz range. This is particularly critical for peripheral devices that are placed close to the PC platform, such as a flash drive. Placement of the wireless antenna should also be carefully considered on a platform and be located as far away as possible from a USB 3.0 connector and/or device“
Even OWC demonstrated in a 2012 video that shielding resolves USB 3.0 conflict with Bluetooth.
Hoping mr J.Srouji, SVP at Apple, takes the topic into consideration
