can i get the frequency band of the wireless network that the imp is connected to?

so i'm planning a deployment of imps across a building. i was wondering if i could use it to map the wifi signal coverage... i see that i can get rssi from the imps, and i can even get a list of ssids... but i what i would like is to get a list of the bssids nearby and also their associated rssi's.... is this available?

also, is there a 5ghz version?
