To all I just came across a Japanese standard about a RFID product at 13.5 MHZ, it says that measurement of FCC from 30m to 3m will need to take the 20dB conversion(ie 20dB/decade) into account.
But I found a statement from FCC part 15.31(f)(2) that at frequency below 30 MHZ, 40/decade extrapolation factor shall be used. I just want to clarify which we should use for measurement below 30MHz, 20dB/decade or 40/decade?
