On the second performance test, we first use network
utility Ping to measure the RTTs and loss rates of data packet
with different packet sizes of 32bytes, 512bytes, and
1518bytes. Referring to Figure 7, the Ping request is sent from
TV station headend in site B1 to an access point W1, which is
a 5.8GHz WiMAX base station and located within repeater
site R1 of backbone site B10 in southern Taiwan. 5000 Ping
requests have been sent during the test and results are shown
in Table III.
