Wi-Fi Direct , initially called Wi-Fi P2P, is a Wi- Fi standard that enables devices to connect easily with each other without requiring a wireless access point and to communicate at typical Wi-Fi speeds for everything from file transfer to Internet connectivity. 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. 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 , a Bluetooth 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 .
