MAY CONTAIN U.S. AND INTERNATIONAL EXPORT CONTROLLED INFORMATION
NOTE: On PCIe AP, prints can be disabled by killing tail -f 1
/proc/net/drivers/wlan0/sirDump application. To enable prints for PCIe AP again, enter 2
/config/prints. 3
2.3.1 View the DFS configuration 4
5
To view the complete active DFS configuration on the AP, use the following command: 6
aniSdkTool -g dfs 0 7
2.3.2 Data Density configuration 8
Data density will need to be modified for the intended bandwidth mode. Data density is modified 9
by issuing the commands below on Tera Term Pro console of LP2. There are two separate 10
commands for data density modifications, one for 40MHz bandwidth mode and one for 20MHz 11
bandwidth mode: 12
Commands for setting data density at 27 Mbps (40MHz bandwidth mode): 13
dump 188 0 14
dump 181 2 82 82 82 15
Commands for setting data density at 26 Mbps (20MHz bandwidth mode): 16
dump 188 0 17
dump 180 2 66 66 66 18
Output: The data density will be increased and the increased data density can be observed on RF 19
spectrum analyzer which is capturing the traffic activities of Qualcomm Master Device. 20
2.3.3 Frequency/channel selection 21
By default, the Qualcomm Master device will boot up in 40MHz mode on primary channel 100 22
and secondary channel 104. The center frequency will be at 5510MHz. 23
For conducting the FCC radar tests, the DUT must be set on certain specific frequencies. The 24
IEEE 802.11n protocol does not allow operation on all the frequencies in 40MHz mode. 25
Only certain pairs of primary and secondary channels are allowed in 40MHz as shown in the table 26
below. For example when the primary channel is selected at 40, the secondary channel of 44 27
cannot be selected. 28
