1. A method for a device for a wireless local area network (WLAN) system to operate in a whitespace spectrum, the method comprising:
- obtaining available channel information from another device;
scanning for access points based on the available channel information; and
determining a center frequency of an operating channel in the WLAN system, wherein the operating channel is determined based on the scanning,wherein the center frequency of the operating channel is determined according to an equation;
C=S+(B*f(bw))+(0.5*B)where C is the center frequency of the operating channel,S is a starting frequency,B is a whitespace channel bandwidth,bw is the operating channel bandwidth,f(bw) is a value determined according to the operating channel bandwidth.
