Abstract
In a wireless device, active scanning for a particular wireless network name is initiated during passive scanning for a wireless network that matches a profile stored in a wireless local area network controller, the profile including the particular wireless network name. Active scanning for the particular wireless network name includes transmitting one or more probe requests, each transmitted on a different communication channel.
Claims8
A method in a wireless device, the method comprising:
- initiating active scanning for a particular wireless network name during passive scanning for a wireless network that matches a profile stored in a wireless local area network controller, said profile including said particular wireless network name,
- wherein active scanning for said particular wireless network name includes transmitting one or more probe requests, each of said one or more probe requests transmitted on a different communication channel.
A wireless device comprising:
- a memory to store profiles of one or more wireless networks;
- a wireless local area network controller that supports passive scanning for wireless networks matching a profile and that supports active scanning for wireless networks having a wireless network name;
- and
- a processor,
- wherein said memory is to store executable code which, when executed by said processor, initiates active scanning by said controller for a particular wireless network name during passive scanning by said controller for a wireless network that matches a profile including said particular wireless network name,
- wherein active scanning for said particular wireless network name includes transmitting one or more probe requests, each of said one or more probe requests transmitted on a different communication channel.
