WICED Studio Wi-Fi Combo

Hi Cypress Team,

I am looking for below details, which i require in one of the product certifications which uses CYW4343W SoC.

1) CYW4343W supports 20MHz channels only. Please confirm.

2) Does the CYW4343W support TPC (Transmit power control)?

Looking for your quick response for the same.

Hello:

     Yes, we often disable 40M bandwidth since there will bring a lot of interference if enabled on 11n.

for TPC, it can be supported on Spec, but it need a confirm from fw side,  would you please tell which firmware you are using ?

Hi,

Below is the Version i found:

WLAN Firmware : wl0: Apr 30 2018 04:14:19 version 7.45.98.50 (r688715 CY) FWID 01-283fcdb9

I read in the Wi-Fi Regulatory document, where is mentions TPC is applicable to 5GHz channels (52-64 and channels 100-144 ). And As we are not using 5GHz band would it be applicable to us?

Hello：

    I have checked the test plan,  I can find it in 11AC test plan , but not found it in 11n plan.

seems i am wrong in last reply,  This is an optional test that depends on if TPC supported.

I think we should support the TPC function,  but need to have a confirm with lab how to test if the chip is 2.4G only .

Hi Thanks for the details,

Can you tell me whether TPC is supported or not, from the firmware version i mentioned?

hello:

    We normally support TPC feature on chip 4343w.

Hello:

    TPC should be a mandatory case for the certification.
