WIPO Patent Application WO/2012/109369

A3

An available Television, TV, frequency band for communication is determined and a frequency fc of a carrier is determined based on the available frequency band. The carrier is set by an access point, AP, to the frequency fc for communicating with one or more communication devices via a first communication channel within the available frequency band. After communicating via the first communication channel, the carrier frequency fc is used for communicating with one or more communication devices via a second communication channel within the available bandwidth. A center frequency of the first channel is different that a center frequency of the second channel. Local oscillator frequency determine available TV channels, TVWS (TV Whitespace) from a database. Obtain available TV channels according to location of access point, AP.
