Abstract
An embodiment of the present invention is a technique for short-range ad-hoc mode communication. An ad-hoc mode is configured for a first mobile station (MS) operating in an ad-hoc network under a broadband wireless standard. An ad-hoc mode communication is acquired having a simplified communication protocol of the broadband wireless standard. A second MS is communicated with using the ad-hoc mode communication.
