WL1273 CuCmd_D_Country_5Ie() support

Other Parts Discussed in Thread: OMAP3530

Hi,

 

I am interetsted in using WL1273 on OMAP35x for a product which can be used all over the world.

 

I have a concern about radio regulations for each country, which specifies permitted/prohibited radio frequency country by country.

It can be possible to detect a country by receiving Country Information Element sent by Access Point in Beacon and uses the information, however, I would like set the Country Information Element to the device without using passive scan.

I could see some APIs in http://processors.wiki.ti.com/images/1/13/WLAN_API_Functions.zip, Regulatory Domain (802.11 d & h) Configuration Functions (partially not supported in current version).

Can they be used for setting right CHs for the target countries? If so, by when can we expect CuCmd_D_Country_5Ie() to be supported?

Really appreciate for the help.

    Hi,

    The OMAP3530 EVM is working with 1271 therefore it supports bgn band only and do not support A band.

    as per your specific question CuCmd_D_Country_5Ie() should set the specific channels that can be supported in A band, however according to the implementation of that function you can see that the parameters are set hardcoded as:

    CountryWorld.elementId = COUNTRY_IE_ID;
    CountryWorld.len = 6;
    os_memcpy((PVOID) CountryWorld.countryIE.CountryString,(PVOID)"US ", 3);
    CountryWorld.countryIE.tripletChannels[0].firstChannelNumber = 36;
    CountryWorld.countryIE.tripletChannels[0].maxTxPowerLevel = 13;
    CountryWorld.countryIE.tripletChannels[0].numberOfChannels = 8;   

    according to the code all the structure for A band support is in there however it was not tested therefore we can not garantte that it works with no issues.

    currently we do not have schedule and plan to support A band in OMAP3530 platform
