Re: WLAN Coverage area detection

I suppose that you might be able to poll for a list of SSID values that you
can hear from the wireless card and, if there are any, you're in a coverage
area, more or less. It's also possible that you might be able to get a
notification from NDIS when the card hears a new SSID. I'm not so sure
about that one, because it's very difficult for me to find a place where I
can put one of my devices where it won't hear *some* SSID.

Are you really wondering if there's *any* SSID values or do you only care
about when you're connected? That you can definitely do by waiting for a
notification from NDIS for the adapter of interest.

There's little C code that I can point you to, other than the source code
for Windows CE. I posted some code a long time ago concerned with
communicating with the Windows Zero Config (WZC), APIs in Windows CE. For
C# or VB.NET, OpenNETCF's Smart Device Framework has a significant amount of
code for seeing what access points you can hear, for setting up
notifications from NDIS, etc. www.opennetcf.org

You might want to say some more about what you're actually trying to
accomplish...

Hi,

Is there a way to programatically determine if a user has entered a WLAN
coverage area using Windows CE5.0?
Is this something that can differ by driver, or is there a standard API we
can use? Thanks!
