RSSI and SNR of WL1271/WL1273

Feb66288

Other Parts Discussed in Thread: WL1271

Dear all,

I'm using a module of WL1271/WL1273 on WinCE6.
To examine the radio environment, I would like to acquire
the value of RSSI and SNR. (Not using for roaming)

In ticon, the value of RSSI is acquired by using TIWLN_802_11_RSSI,
and the value of SNR is acquired by using TWD_SNR_RATIO_PARAM.
Are these acquired values average value or real-time value?

If it is a average value, I would like to change the time of
sampling of RSSI. Please teach me how to change the time.

Best regards,

Please refer to the following threads to see how RSSI is determined and reported in the Linux WiLink driver on the omap35x EVM;

Dear Sinoj,

Thank you for your reply.
But, the answer in these threads is not clearly written whether average or real-time.
In addition, the answer is only written about roaming triggers.

I would like to know that the value I acquired from FW is the average value or real-time value.
Please teach me clearly that the value of RSSI and SNR acquired from FW is average or real-time.

Best regards,

Hi,

Shlomi described that the RSSI/SNR acquired from the FW is average.

Thanks,
