Peer-to-Peer Airplay is part of the exciting and eagerly anticipated new feature of the recent updates to Apple TV (iOS7) and iPad iOS8 and will be a useful feature for teachers with iPads.
Peer-to-Peer Airplay allows you to connect and mirror the screen of your iPad or Mac laptop to a TV screen, using an Apple TV, without connecting the devices to the same wifi, network.
This fantastic feature for education, is limited to the lasted version of Apple TV. Which is a real shame, something I’ve just discovered, while trying to make this work. The Apple TV model number you require is; Apple TV third-generation rev A (model A1469) You can find this serial number on the bottom of your Apple TV. You may need a magnifying glass to see it!
