Wi-Fi Direct Lets Wi-Fi Devices Connect
The Wi-Fi Alliance today announced the first set of devices that have been certified with the Wi-Fi Direct technology. Wi-Fi Direct will let devices such as mobile phones, cameras, printers, laptops, keyboards and headphones to connect with one another directly — without the need for a nearby Wi-Fi hotspot. The spec will allow for one-to-one connections, as well as mesh-style group connections. According to the Wi-Fi Alliance, the specification will include WPA2 security features for businesses, though the spec will be targeted at both consumer and business devices. Any device labeled with the "Wi-Fi Certified Wi-Fi Direct" icon will be compatible. The specification will be limited to the current capabilities of Wi-Fi with respect to distance (100 meters) and data transfer speeds. Existing devices should be able to upgrade to Wi-Fi Direct with a software update. These first devices are integrated chips meant for laptops. The Wi-Fi alliance hasn't said if or when cell phones will be approved for Wi-Fi Direct. Wi-Fi Direct competes with Bluetooth 3.0+HS. Wi-Fi Direct was first announced in October 2009.
