What do you mean by secondary wifi connection? It cannot connect to a router, so it won't be wifi in that sense. You can connect to devices via blue-tooth. For example, I have given presentations where my iPad was connect to a project and its screen was on the screen....then I used my phone to send the talk over BT connection to the iPad..then I controled the talk from my phone as I was free to move around the room.
You can connect speakers and other devices via BT to your phone. But as far as I know, it doesn't have the bandwidth to do what a real wifi connection can do. It can stream audio and send files.
