Abstract:
A method for switching channels in a wireless communication network comprising at least one access point and clients, wherein the communication network as secondary user uses one of a number of possible channels for data communication. In accordance with the invention, data communication occurs between the access point and the number of clients through the first transmit/receive interface of the access point on a first channel. Parallel to the data communication, a check of the possible channels occurs over the transmit/receive interface by a second transmit/receive interface of the access point to determine which of the channels are free channels that are not being used by any primary users. A channel switch from the first channel to one of the free channels occurs if a prioritized use of the first channel by a primary user is established by the access point of the communication network.
