Dear Cypress technical team

We are developing the WLAN system beased on CYW43907 module.
Now we are working on the radio certificatoin for Japan TELEC.
But we found the issue on 11b-14ch during the test (using Cypress WL tool).

According with TELEC Japan 14ch spec,
Spreading Rate of RF Spectrum
14ch    >= 10
1-13ch  >=5

However, current CYW43907 shows the following result.
14ch  = 6.43  (should be more than 10)
1-13ch = around 6.43    ---> This is OK

In order to get 14ch Spreading Rate more than 10,
we need to get your support ASAP.

Please help!!

Cypress does not support ch. 14 so unfortunately there is no solution to this issue.

Have you used the CLM blob in WICED production release to test the spreading rate? Which WL commands did you use for testing? May I know the partner module that you are currently using?

Yes, we are using  the CLM blob in WICED.
WLAN CLM:
API: 12.2 Data: 9.10.74 Compiler: 1.31.3 ClmImport:  1.36.3 Creation: 2018-05-15 19:33:2
Also, using Manufacturing Test Application: 802.11b Tx Test Commands.

We are using Murata module 'LBWA1UZ1GC'.
Actually, LBWA1UZ1GC has been certified 2.4G 1-3ch & 5G Radio, except 11b-14ch.

11b-14ch support is mandatory for our customer system product,
therefore we are proceeding the additional 11b-14ch test certification.
