Link Control

The Link Control page features the RF Link Loopback / Speed Test. In this test, the user specifies the transmission rate (in Mbps) in both the local radio and the peer radio as well as the duration time (in minutes) for the test. During the test, the local radio will transmit packets across the wireless link. The peer radio will retransmit equivalent packets back to the local radio. The test will measure and report error rate and actual throughput as measured in Mbps. The following link test was run for 60 seconds with a specified TX rate of 54 Mbps per end.

To run a link loopback test, both radios must be in Opmode ON and status “Connected”

In this example, the error rate was 0 packets from MU to RU and 0 packets from RU to MU. Measured aggregate bandwidth is 43.39 Mbps.
