When I click on the WiFi symbol in the menu bar on my Mac I get a list of wireless networks, most of them with little lock icons next to them. But some of them show what looks like a pair of chain links instead (see image below). What does this mean? That these networks are personal hotspots?

It's a personal hotspot created by an iOS device to share the cellular data connection that the phone has over Wi-Fi.
