I need to make a presentation in a place where there is no internet or open networks Im also not allowed to bring routers of any type. I would like to use my iPhone as a remote for the presentation. What Can I do?
You don't need an internet connection to use Keynote Remote, but you do need a WiFi signal that the iPhone and Mac are connected to. As you will not have WiFi available, use an RF remote instead, we use the Logitech Spotlight and Gyration Air Mouse which are much more reliable than an iPhone.
