Rx Noise vs SNR


#1

Someone could help me to understand value reported into B5-lite.

Only for test I’m running a 755 mt. link in 6160Mhz freq. The strange thing I noted is Rx Noise and SNR obtained value compared with PHY and MAC Data Rates.

With an -38 Rx Noise how can be possible to obatin a 263/263 real throughput ?

Where I’m wrong ?

Hi Massimiliano,

The noise value includes adjacent channel noise. TPC uses this information to avoid reducing Tx power to improve EVM as the higher PER would likely cause PHY rate fluctuations.
