Wi-Fi CERTIFIED Wi-Fi Direct®: Personal, portable Wi-Fi® technology (2014)
Wi-Fi CERTIFIED Wi-Fi Direct® devices connect in a way that makes it more simple and convenient than ever for users to print, share, sync, and display. Wi-Fi Direct devices can connect directly to one another without access to a traditional network, so mobile phones, cameras, printers, PCs, and gaming devices can connect to each other directly to transfer content and share applications anytime and anywhere. Devices can make a one-to-one connection, or a group of several devices can connect simultaneously. They can connect for a single exchange, or they can retain the memory of the connection and link together each time they are in proximity.
Around the globe, people are creating, storing, accessing and sharing more songs, videos, pictures and documents than ever before. They are used to gathering around a single digital camera to look at pictures with friends and family, or around a single handheld or laptop screen to watch videos. Wi-Fi Direct products allow them to connect directly with each other’s devices to share those pictures, games and video, or display them on a nearby monitor or TV for easy viewing.
In 2010, Wi-Fi Alliance® introduced the Wi-Fi Peer-to-Peer Specification and Wi-Fi CERTIFIED Wi-Fi Direct certification program, dramatically expanding peer-to-peer connectivity for consumers by introducing an interoperable technology with distinctive new features.
Published in 2014, the Wi-Fi Peer-to-Peer Services Specification builds directly on the Wi-Fi Peer-to-Peer Specification and provides new enhancements of service advertising and discovery, session management and an industry-standard services platform with four common services to allow end users to easily send files, print documents, play and interactively display media between devices from different manufacturers. In addition, an application programming interface (API) enables third-party developers to easily take advantage of Wi-Fi® P2P capabilities.
This white paper describes Wi-Fi Peer-to-Peer technology (P2P) and the new service features available. Wi-Fi CERTIFIED™ devices implementing this technology will bear the certification mark Wi-Fi CERTIFIED Wi-Fi Direct®. A technical description of the technology can be found in the Wi-Fi Peer-to-Peer Specification and Wi-Fi Peer-to-Peer Services Specification.
