For narrow band systems a too large frequency offset between the TX and RX devices could result in no link or a very poor link.
The minimum required RX bandwidth to ensure reception is given by:
For FSK the signal bandwidth can be approximated as data rate + 2*frequency deviation (Carson’s rule).
For CC13x0: For low data rates, the bit repetition patch CC13x0 Low Data Rate Operation should be used. If this patch is not used, the frequency offset tolerance could be under 10 ppm, which could cause loss of link with a normal crystal tolerance.
