I am looking for something close to what the original OP was asking for, but for a different purpose. Rather than starting a new thread, I thought I would ask on here. If I don't get responses, I'll try a different thread.
I work a lot of trade shows, and like to play videos, and show product info with an iPad to a TV monitor. I currently use an Apple TV, and use airplay to put my iPad info to the monitor. The problem with this approach is that I am in a convention center that does not have a private (or even a public) wifi network. Therefore, I have to bring along a wireless router that both the Apple TV, and the iPad can connect to, in order to work. I originally brought an airport express to generate the wireless network, but that would not work without a wired internet connection (which did not exist in the convention center)
My ideal solution would be a wireless device that could generate the wifi signal (basically being it's own webserver) that the iPad could connect to via airplay, and stream directly to that. I don't like needing to bring along my own wireless network for both the Apple TV and iPad to connect to.
Does anyone know of a way to do this wireless, without the need to bring along a seperate router just to create the wireless network?
Thanks
