Roku’s $99 Streaming Stick passed through the FCC today, winning approval for WiFi operation in 2.4GHz and 5GHz bands.  Unlike Roku’s streaming video boxes, the Streaming Stick is a self-contained device that plugs directly in to a TV’s MHL port thus eliminating the need for power and HDMI cords.

So far, only a handful of television manufacturers, including Haier, Hitachi, Insignia and Mitsubishi, have announced plans to offer Roku Ready products.  However, the MHL Consortium does include notable TV manufacturers like LG, Sharp, Sony and Toshiba.

Roku plans to launch the Streaming Stick in October 2012 for $99.
