    "Wi-Fi Direct knows what's nearby
    Wi-Fi Direct includes two potentially useful things: Wi-Fi Direct Device Discovery and Service Discovery. Your device doesn't just know there are devices available; if developers have enabled it, your device will know what kind of devices are nearby and what's on offer - so for example if you're trying to display an image, you'll only see devices that you can beam images to; if you want to print, you'll only see devices that are or that are connected to printers. Crucially this can happen before you connect, so you don't waste any time trying to connect so something that doesn't do what you want it to do."
