A page of notes on network throughput testing on BBHN.
Not ideal but I determine the average received SNR from observing the Auto SNR page on the BBHN node, wait for it to settle and “by eye” make a note of where the average SNR is during the iperf test.
SNR and noise levels fluctuate wildly in the indoor non-line-of-sight multipath environment as shown below:

…so this testing is performed outdoors in a rural environment with clear line-of-sight between nodes:
