Abstract
In a communication network, a wireless channel is selected from multiple channels. The interference level of the selected channel is determined and a first quality value is derived and compared to a first decision threshold. If the first quality value is smaller than the first decision threshold, the selected channel is abandoned and a new channel is searched. If the first quality value is greater than the first decision threshold, the selected channel is maintained for transmission of a packet. A second quality value of the maintained channel is continuously determined and compared to a second decision threshold which is lower than the first decision threshold. Only if the second quality value is smaller than the second decision threshold, the channel is abandoned and a channel search is initiated.
