Wi-Fi Direct
Wi-Fi Direct, initially called Wi-Fi P2P, is aWi-Fi standard that enables devices to connect easily with each other without requiring a wireless access point[2] and to communicate at typical Wi-Fi speeds[3] for everything from file transfer to Internet connectivity.[4][5] One advantage of Wi-Fi Direct is the ability to connect devices even if they are from different manufacturers. Only one of the Wi-Fi devices needs to be compliant with Wi-Fi Direct to establish a peer-to-peer connection that transfers data directly between each other with greatly reduced setup.[citation needed] Wi-Fi Direct negotiates the link with a Wi-Fi Protected Setup system that assigns each device a limited wireless access point. The "pairing" of Wi-Fi Direct devices can be set up to require the proximity of a near field communication, aBluetooth signal, or a button press on one or all the devices. Wi-Fi Direct may not only replace the need for routers, but may also replace the need of Bluetooth for applications that do not rely on low energy.[6]
