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:
1. SUPERBEAM app
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).
