Is there a way to view the type o encryption used by wireless neworks within wifi range?

It seams to be quite easy to check that with the use of an i-Phone or other wi-device.
But while scanning with my r-52 card, I can not see what encryptions are being used by networks in range.

How else can I check wich ones are available?

Thanks

Isn't there anyone that can help?

I want to find out how can I see the type of encryption used by all available WiFi networks.
