A method of controlling utilization of plurality of frequency channels in a wireless communication network, the method comprising: A) an access node of the wireless communication network assigning a selection probability to each of the frequency channels; B) on the basis of the selection probabilities, the access node randomly selecting one of the frequency channels as current operating frequency channel of the access node; C) the access node determining a channel quality of the current operating frequency channel; D) in response to the channel quality of the current operating frequency channel complying with a configured selection criterion, the access node maintaining the current operating frequency channel; E) in response to the channel quality of the current operating frequency channel not complying with the configured selection criterion, the access node selecting randomly on the basis of the selection probabilities a further one of the frequency channels for evaluation and comparing a channel quality of the frequency channel selected for evaluation to the channel quality of the current operating frequency channel; E1) in response to the channel quality of the frequency channel selected for evaluation being higher than the channel quality of the current operating frequency channel, the access node setting the frequency channel selected for evaluation as new operating frequency channel of the access node; and E2) in response to the channel quality of the frequency channel selected for evaluation not being higher than the channel quality of the current operating frequency channel, the access node maintaining the current operating frequency channel and decrementing the selection probability assigned to the frequency channel selected for evaluation.
