WLAN

Hello,

I am developing a site survey application using native wifi api supported by Vista & XP + SP2. I can retrieve values like MAC address of Access Point, SSID, Wireless Mode, rssi etc.

But I would like to show some more values like Noise Floor, Signal To Noise ratio (SNR) and Received Data Rate value to the User. So Is there anyway to get those values

Any idea is appreciated...

Thanks in Advance...

Hi, try using WlanQueryInterface (http://msdn2.microsoft.com/en-us/library/ms706765.aspx) with OpCode set to wlan_intf_opcode_current_connection. The wlanAssociationAttributes member of the returned WLAN_CONNECTION_ATTRIBUTES structure has info about the signal quality and the transfer rate.

WlanQueryInterface can query only signal strength and receiving data rate information. But how do I get other values like channel noise / noise floor.

Is there anyway to retrieve it directly using wifi API

or

Do I need to use any vendor specific API because I have seen OID_ATH_NOISE_FLOOR OID in Atheros driver source code. So Is there anyway to access it

Not that I know of, sorry. I suggest you follow up with Atheros support if you want to access that specific OID.
