NOTE: At the completion of the AIM cycle, a throughput test is performed. It is
important to note that this value is performed at Best Effort. Therefore the value may
be skewed if other Subscriber Units are currently sending traffic. Also, it is most
likely that when the throughput test is started, the forward error correction and mod-
ulation is at its most robust value. This causes the initial portion of the throughput to
possibly be slower at the beginning of the test, once again skewing the throughput
speed. A more accurate value may be obtained by re-running the throughput test.
d. After the ping test, the AIM performs a throughput test (an FTP transfer of 1
megabyte of data up and down the wireless link), displaying the window
shown in Figure 5-15.

e. This test may take a few minutes to complete, depending upon the signal
characteristics. If you are not interested in the throughput test, or if the
throughput test takes more than 10 minutes, click on the Stop button.
f. When the throughput test is finished or stopped, the window shown in
Figure 5-16 is displayed, showing results of the ping and throughput tests.
These results and RF transmission results are recorded in a text file with
the name of the IP address, in the directory in which the AIM application
is loaded (normally C:\aim). Each time the Setup or Test function suc-
cessfully executes, this file is updated.
