FIELD: radio engineering, communication.
SUBSTANCE: invention relates to a method for a first coordinator operating at a first channel frequency in a wireless personal area network (WPAN), the WPAN further comprising a second coordinator operating a second channel frequency. Each coordinator is capable for compelling a coordinator with which it needs to communicate to switch to its chosen frequency. The method comprises steps of transmitting a message at a plurality of channel frequencies including the second channel frequency, requesting the second coordinator to switch from the second channel frequency to the first channel frequency, and communicating with the second coordinator using the first channel frequency.
EFFECT: no priority based mechanism is needed due to the fact that the coordinator which initiates (eg starts) communication selects the used frequency.
