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.
Claims20
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.
1 more element
A device, comprising:
- an RF transceiver operated by a processor that is capable of operating in a 2.4 GHz band and a 5 GHz band;
- wherein the processor is configured to:
- as a group owner, establish a direct communications service with one or more other devices using the 2.4 GHz band;
- scan one or more DFS-required channels of the 5 GHz band for radar or other activity to determine their availability;
- if one or more channels of the 5 GHz band are available, move 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.
