Method and apparatus of converting TV channels into WLAN channels in a wireless local area network system

摘要

A method of converting TV channels into WLAN channels in a wireless local area network system (WLAN) is disclosed. A method of converting TV channels into WLAN channels at an apparatus comprising receiving WSM including a list of available TV channels and finding out a center frequency of each of first WLAN channels which exist on frequency area of the available TV channels using TV channel bandwidth, WLAN channel bandwidth and a starting frequency of each of the available TV channels, wherein the TV channel bandwidth and the WLAN channel bandwidth are predetermined.

主权项

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.
