Abstract:
A method of establishing a channel in a wireless communication network, comprising the steps of:a) selecting a wireless channel from a plurality of wireless channels; b) detecting interference level of the selected channel and determining therefrom a first quality value and comparing the first quality value to a first decision threshold; c) if the first quality value is smaller than the first decision threshold, returning to the step (a) to select another channel; d) if the first quality value is greater than the first decision threshold, using the selected channel for transmission of a packet; e) determining a second quality value of the maintained channel and comparing the second quality value to a second decision threshold which is lower than the first decision threshold; f) if the second quality value is smaller than the second decision threshold, returning to the step (a) to select another channel; and g) if the second quality value is greater than the second decision threshold, maintaining the used channel and returning to the step (e).
