New specification to support direct Wi-Fi connections between devices

The Wi-Fi Alliance is nearing completion of a new specification to enable Wi-Fi devices to connect to one another without joining a traditional home, office, or hotspot network. The Wi-Fi Alliance expects to begin certification for this new specification in mid-2010, and products which achieve the certification will be designated Wi-Fi CERTIFIED Wi-Fi Direct.

The specification, previously code-named “Wi-Fi peer-to-peer,” can be implemented in any Wi-Fi device, from mobile phones, cameras, printers, and notebook computers, to human interface devices such as keyboards and headphones. Significantly, devices that have been certified to the new specification will also be able to create connections with hundreds of millions of Wi-Fi CERTIFIED legacy devices already in use. Devices will be able to make a one-to-one connection, or a group of several devices can connect simultaneously.

The specification targets both consumer electronics and enterprise applications, provides management features for enterprise environments, and includes WPA2 security. Devices that support the specification will be able to discover one another and advertise available services. Wi-Fi CERTIFIED Wi-Fi Direct devices will support typical Wi-Fi ranges and the same data rates as can be achieved with an infrastructure connection, so devices can connect from across a home or office and conduct bandwidth-hungry tasks with ease.
