Passively Scanning According to WLAN Regulatory Domain
First Claim
Patent Images
1. A wireless device comprising:
- a processor;
a wireless local area network (WLAN) interface coupled to the processor;
another wireless interface coupled to the processor; and
a memory to store code which, when executed by the processor, determines a WLAN regulatory domain in which the device is currently located using information received via the other wireless interface, and which controls the WLAN interface to passively scan for wireless local area networks on channels in the 5 GHz band that are valid in the WLAN regulatory domain and to refrain from passively scanning for wireless local area networks on channels in the 5 GHz band that are not valid in the WLAN regulatory domain.

Abstract
A wireless local area network (WLAN) client device determines the WLAN regulatory domain in which it is currently located by using information received via a non-WLAN wireless interface. Once the regulatory domain has been determined, a WLAN client device operating in the 5 GHz band, for example, an IEEE 802.11a client device, may passively scan for wireless local area networks on channels in the 5 GHz band that are valid in the regulatory domain and may refrain from passively scanning on channels in the 5 GHz band that are not valid in the regulatory domain.
