Fig. 3.9 A typical readout after running Iperf for duration of 10 seconds. In this test the UDP source was set to
50Mbps. Since the link could only sustain 42.7Mbps 16% of the datagrams were lost.
4. Test Procedure
An extensive test plan had been developed to do complete testing on the Redline equipment and
evaluate its suitability to meet the needs of AAC. A copy of the test plan can be found in
appendix 5. The test plan was completed with the exception of doing point to multipoint mode
testing due to a hardware failure in the base station terminal. The interference testing had to be
modified as well.
The first test was designed to determine the effects of packet size on throughput. The test bed
was configured using architecture A shown in Figure 3.2. The size of the UDP packets were
varied by setting the packet size parameter on the IP-Traffic generator screen to the desired
value. The interpacket delay was then automatically controlled by IP Traffic to keep a
throughput value of 50Mbps, as was specified in the throughput field. The use of flow control
limited the throughput to whatever the capacity of the radio link was for that size of packet. This
throughput value is what was recorded in the raw data logs taken by IP Traffic. The traffic
