[W-MBUS] “in order to assess the SNR threshold of my RC1700HP-MBUS device, I’m mixing the signal from the 169 MHz gateway to the Meter with a white gaussian noise signal. In order to compute the actual received noise power, I should know the amplitude of any filter present in the receiving stage. According to the standard, channels 1a/b, 2a/b and 3a/b have a width of 12.5 kHz and therefore I’m simply supposing that a filter with a bandwidth approx. equal to 12.5 kHz will be present somewhere at the receiver. Could you please confirm my assumption? “
Yes, your assumption is correct. Receiver filter is 12.5 kHz.
