Can you connect iPhone/iPad to Apple TV without WiFi network in place I would like to make a presentation from an iPhone or iPad using an AppleTV and projector. Is it possible to do so without either a WiFi or LAN network in place (like in a bad hotel)? Is the AppleTV able to act as a WiFi/Bluetooth access point so that iDevice can connect to it and show the presentation? Or is that not possible? 

Are there any workarounds for this, or do I have to bring wireless router with me as well?
You cannot connect directly to the Apple TV, so you will have to bring a router.
