The Wi-Fi Alliance plans a new specification “Wi-Fi Direct” to support device-to-device connections over same range and as same speed as Wi-Fi, but without a hotspot or access point. Security features built into the Wi-Fi Direct specification will prevent peer-to-peer devices from compromising corporate networks.
The specification 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.
