Site Survey Active Mode Parameters (continued)
Description
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:
Default: 11 Mbps (2.4-GHz client adapters);
The delay (in milliseconds) between successive transmissions.
Range: 1 to 2048 ms
Default: 50 ms
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
The packet type that is transmitted during the test.

54 Mbps (5-GHz client adapters)
Description
When unicast packets are used, the system
expects to receive an acknowledgment
from the destination, and retries can occur.
When multicast packets are used, no
packet retries occur during the test.
