First Claim
Patent Images
1. A method for operating a device having an RF transceiver capable of operating in a 2.4 GHz band and a 5 GHz band, comprising:
- as a group owner, establishing a direct communications service with one or more other devices using the 2.4 GHz band;
scanning one or more DFS-required channels of the 5 GHz band for radar or other activity to determine their availability; and
if one or more channels of the 5 GHz band are available, moving at least part of the 2.4 GHz communications service with the other device to the 5 GHz band if a higher quality of service is needed by the communications session.

Abstract
A method and system for allowing a client device to establish a direct communications session such as Wi-Fi Direct service using the 5 GHz band. In one embodiment, a client device first establishes a direct communications session, in the 2.4 GHz band with another client device, and then, based on the content used in that service, establishes a 5 GHz service if needed.
