Hi All,

Is there any thumb rule about data rate and sensitivity? If the sensitivity of a transceiver at 1M data rate is 90dBm, how much sensitivity could be obtained when operating at 250K data rate?

this is the relation between the sensitivity and the data rate:

P=log10(NF)+10log10(KT)+10log10(Eb/N0)+10loag10(Rb)


SO,you should calculate this formulation
