Some interesting selected findings

From the PDF report:

The furthest useable signal attained reached out to approximately 4.35 miles away from the WiMAX base station, using the outdoor CPE and 1.05 miles using the indoor CPE.

The test concluded that we were able to get a maximum of 7.5 Mbps download and over 8.9 Mbps in upload speed.

The test data shows the WiMAX network to provide adequate performance to be able to deliver streaming media encoded up to 4Mb/s.... The lab testing did not reveal any issues at the 700Kb or 2Mb rates. The 4Mb stream revealed only minimal issues. Data discards on the downlink measured 0.000341% and no discards on the uplink.

Average round trip latency was approx 44 msec.

Re: Some interesting selected findings

For a signal to go 4.35 miles and then come back, it should take 46.7 microseconds. 44 milliseconds is an increase in latency by a factor of 1000. Can processing a ping really create that much overhead?

That number was for a video streaming application and not a ping. It includes all the delay in both the hardware and the application.
