5. Performance tests
A. Throughput measurements. We will conduct a series of lab bench performance tests to
measure throughput versus offered load in several configurations:
A) P2P: one subscriber station used as a reference
B) PMP: two subscriber stations
C) PMP: three subscriber stations (simulate birdstrike scenario)
In each of these tests, we will use the traffic generation software to measure actual packets
received versus offered load with different amounts of traffic on the different channels (B and C)
and also with different input bit rates. The objectives are to establish the efficiency of the AN50
MAC layer and to verify that the through specifications can be realized. These are given in
Figure 7.

B. Throughput versus path loss measurements. We will emulate path loss using combinations of
fixed and variable attenuators to test the radio system in P2P and PMP configurations:
• P2P) increase signal attenuation while observing packet loss and throughput statistics
