BBHN link throughput

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:

Received SNR can fluctuate wildly in the indoor non-line-of-sight multipath environment. Noise level is much higher and variable too.

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

Received SNR and noise levels are much more stable in a rural setting with clear line-of-sight between nodes. The SNR waterfall here shows the disturbance as the node is being moved by my helper (blocking LOS) and then SNR settles after the node is placed and the helper moves away.
