Throughput Vs SNR Measurement in Lab: Setup

Set up:

Variable Attenuator:

   We used  a combination of 4 attenuators :-

• 70 dB attenuator (steps of 10 dB)

• 11 dB attenuator (steps of 1 dB)

• 32 dB fixed attenuator

Process:  

All of these attenuators & Cable were first calibrated with the help of "Network Analyzer".

    Now "Access Point" was set up to deliver 100 mw (20 dBm) &  ACU utility was run on the Laptop. Then "Signal Strength", "SNR", & "Throughput" readings were recorded. Same was repeated for different attenuation values.
