New Wi-Fi Spec to Permit Direct Device-to-Device Linking
Oct 14, 2009, 7:36 AM by Eric M. Zeman
Today the Wi-Fi Alliance announced a new specification for Wi-Fi technology, called Wi-Fi Direct. Once implemented, 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. The Wi-Fi Alliance expects to begin certifying devices with Wi-Fi Direct by the middle of 2010.
