You know that Claude Elwood Shannon defined the maximum data rate that
can be transmit over a channel bandwidth W and says that this capacity
So in the Wi-Fi (802.11) the modulation is DSSS (Direct Sequence
Spread Spectrum) with 11 Mchips/s in 22 MHz of bandwith...
So with the above equation we can find that the mimimum S/N for this
chip rate is - 3.8 dB ? Is it correct ?
Like the noise floor for this bandwith is -174dBm + 10.log(W) = -100
Then the minimum sensitivity becomes : -103.8 dBm
If we assume that the noise figure of the radio frequency stage is 3
dB (better case, I think)
Then the minimum sensitivity is -100.8 dBm
It's the lower limit for the 802.11 ?
What do you think about this reflexion ?
Perhaps I have made mistakes...
