It is most likely just the network manager scanning for available access points. If it concerns you you can go into System -> administration -> network and create a profile with the "roaming mode" disables on the wireless.
I had to do something similar as I found that the network-manager scanning for AP's would cause a regular and annoying drop-out in Skype calls. So I created a profile for my home wireless network where the wireless is manually configured which I called "Home" and I save the default set up as a profile called "Roaming" for when I'm out and about.
Hope this helps,
