Hello, all
I am using USRP1 board with RFX Transceivers and I want to know the
receiver sensitivity of the daugterboards. For example, for BER less
than 1e-5 and data rate 54Mbps, the 802.11a standard specifies the
receiver sensitivity to be at least -65dbm. Once the receiver
sensitivity is known, the transmission range will be determined, so i
want to know the sensitivity for the RFX boards. Could anyone tell me?
Thank you!
Sensitivity is a very hard parameter to define, since it depends on many
factors including the modulation system in use. The best way to spec a
general radio is with the noise figure. The RFX boards all have a noise
figure in the 6-10 dB range. If you need one lower than that you can
use an LNA in front of it.
