Performance tests

We tested throughput rate over distance while connecting to a Celona network with a Celona Indoor Access Point. The following data shows Signal strength, RSCP, and RSSI reported by the netsh mbn show interfaces command and download and upload throughput via the iperf3 utility.

For these open air performance testing, we raised the Celona Access Point to 12' height in a ceiling mount. While we have seen wide throughput variance at distances beyond 70 yards/210 feet, we recorded the maximum performance observed over multiple runs with 10 second iperf3 data transfers.
