  If I use free WiFi in a hotspot, can data be easily sniffed?  




Let's say I am browsing an HTTP accessible web site (i.e. NOT HTTPS) , is the traffic encrypted through the WiFi connection?

In other words, is there "data privacy" functionality over WiFi regardless of higher layer protocols?
Your traffic is encrypted if the routers setting allow it. This can be WEP, WPA, WPA2. However with all of these the key is known by everyone on the network so it is possible to decrypt the  traffic.
