WiFi Direct

What can I do with wifi direct?
Wi-Fi Direct, initially called Wi-Fi P2P (Peer-to-Peer), is a Wi-Fi standard enabling devices to easily connect with each other without requiring a wireless access point(AP). It is usable for everything from internet browsing to file transfer, and to communicate with more than one device simultaneously at typical Wi-Fi speeds.
uses of wifi direct:
Wi-Fi Direct allows two devices to establish a direct, peer-to-peer Wi-Fi connection without requiring a wireless router. Wi-Fi becomes a way of communicating wirelessly, like Bluetooth. Wi-Fi Direct is similar in concept to “ad-hoc”Wi-Fi mode.
Range of a Wi Fi Direct connection between two devices?
Wi-Fi CERTIFIED Wi-Fi Direct devices work just like any Wi-Fi device, with ranges up to 200 meters. They can connect from just a few feet away, but also across a home. This means that making a Wi-Fi Direct group connection will be convenient, even when devices aren’t in immediate proximity to one another.
Real world application perspective example:
SuperBeam is the easiest and fastest way to share large files between Android devices using WiFi direct. Devices can be paired using QR codes (with the included QR code scanner) , NFC or manual sharing key (PRO).
