in dBm.
Data Rate
The bit rate at which packets are transmitted. Rate shifting does not
occur during the test because the echo test built into the radio firmware
does not support it.
Value:
1, 2, 5.5, or 11 Mbps (2.4-GHz client adapters);
6, 9, 12, 18, 24, 36, 48, or 54 Mbps (5-GHz client adapters)
Default: 11 Mbps (2.4-GHz client adapters);
54 Mbps (5-GHz client adapters)
Delay Between Packets
The delay (in milliseconds) between successive transmissions.
Range:
1 to 2048 ms
Default: 50 ms
Percent Success Threshold
The percentage of packets that are not lost.
This parameter controls the red line on the Percent Successful
histogram. Percentages greater than or equal to this value are displayed
as green bars; percentages below this value are displayed as yellow
bars.
Range:
0 to 100%
Default: 75
Packet Tx Type
The packet type that is transmitted during the test.
Default: Unicast
Packet Type
Description
Unicast
When unicast packets are used, the system
expects to receive an acknowledgment
from the destination, and retries can occur.
Multicast
When multicast packets are used, no
packet retries occur during the test.
