Starting in 2010, new versions of gadgets like cameras, cell phones and PCs will be able to talk to each other using WiFi without connecting to a network first. The WiFi Alliance, an industry group announced that it’s nearly finished putting together a WiFi Direct specification, a set of “rules” that guide companies to add the new capability. Kelly Davis-Felner, the WiFi Alliance’s marketing director, said WiFi Direct will make it easier to liberate the gigabytes of digital family photos that are trapped in cameras, phones or PCs. Now those gadgets will be able to connect directly to digital photo frames, TVs or printers. In creating the specification, the Alliance is moving into the territory of Bluetooth, a wireless technology that already handles direct gadget-to-gadget connections. Bluetooth uses less power but has much shorter range and a lower transfer speed. To tackle the latter problem, the industry group behind Bluetooth announced last year that it would co-opt WiFi technology to make it possible to send videos and other large files around the house, much as Wi-Fi Direct promises to do. Only one of the gadgets need have the new WiFi Direct technology to make a two-way connection work. In one scenario, you could connect a smartphone with WiFi Direct to a laptop and piggyback on its wired Internet connection for a quick email check without tapping your phone’s data plan.
