What is Wi-FI Direct?• Wi-Fi Wifi-Direct is an emerging specification aimed at

making often temporary WLAN connections easier to establish

• Multiple interesting use cases– Two mobile devices that wish to exchange data, play a multi-

player game, etc but have no existing WLAN connection– One mobile device wants to share multimedia (pictures,

videos, songs, etc.) to another device (such as a television, or a STB) at a friends house

– One company visiting another company’s campus wants to connect to a wireless projector or printer

• In all cases, no permanent network information need be shared to make connections– Home user doesn’t have to give out his WPA-PSK passphrase– Corporate user doesn’t have to compromise company
