I recently built a Bluetooth transmitter that can advertise by transmitting binary bits at 5gbps, which has essentially the same physical characteristics as USB 3.0 [1]. Whereas I used an FPGA, I wonder if one could intermingle the right bits amidst the rest of the USB 3.0 protocol to build a bluetooth transmitter...
It's not surprising but still insane that so many USB cables aren't properly shielded, thus making all of the FCC's efforts regulating devices effectively useless as your USB cable turns into an antenna to transmit garbage.
