2Demonstration: Wi-Fi Peer to Peer Connectivity
Peer to Peer Certification Program
• An upcoming certification program from the Wi-Fi Alliance – Wi-Fi CERTIFIED™ Wi-Fi Direct
• Demos from– Intel
• Presenter: Greg Wen, Field Application Engineer
– Atheros• Presenter: Dr. Pen C Li, Product Marketing Manager
3Demonstration: Wi-Fi Peer to Peer Connectivity
Wi-Fi CERTIFIED Wi-Fi Direct : Connect devices, even without a Wi-Fi network
• Wi-Fi Peer-to-Peer technology will enable users to connect Wi-Fi CERTIFIED Wi-Fi Direct devices to each other anywhere - with or without a Wi-Fi network, hotspot or internet connection available
• Connect two or more devices, quickly and easily, to enable applications such as: • Print a picture directly from your camera• Share music directly with a friend• Synchronize contacts, music, etc.• Display pictures directly from your mobile phone on a television
• First Wi-Fi CERTIFIED Wi-Fi Direct products to be introduced in early 2010

Wi-Fi is the right technology for Peer-to-Peer connectivity
• More than half a billion people use Wi-Fi today – it is one of the best-known, best-loved technologies in the world
• Works with hundreds of millions of legacy Wi-Fi CERTIFIED products in use today (802.11 a/g/n)
• Wi-Fi speed (up to 250 Mbps) and range (from <1 m to 200m)
• A single, affordable, proven technology, available worldwide
• Easy configuration with Wi-Fi Protected Setup™ and standards-based WPA2® security
• Leverages standards-based power saving and QoS mechanisms
• IP-friendly: can be used to connect to IP-based home network devices

Wi-Fi Peer-to-Peer: High level specification overview
• Wi-Fi Peer-to-Peer adds new features to enable users to more naturally discover and pair their devices– P2P Discovery scans for other P2P devices and discovers their functionality prior to
actual association
• Wi-Fi Peer-to-Peer also adds new features for better device Power Management – Notice of Absence
• To enable Enterprise adoptions Wi-Fi Peer to Peer has also created a number of features to allow robust management of P2P devices by IT managers– Enterprise can detect P2P, turn off P2P, suggest the channel on which P2P operates
and can suggest transmit power and EDCA parameters
