Abstract
The present 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, the method comprising the steps of transmitting a message at a plurality of channel frequencies including the second channel frequency, requesting the second coordinator to change from the second channel frequency to the first channel frequency, and communicating with the second coordinator using the first channel frequency. As discussed above, advantages with the present invention includes that no priority based mechanism is needed due to the fact that the coordinator that initiates (e.g. starts) communication-decides on used frequency. Furthermore, every coordinator is able to have the coordinator it wants to communicate with to change to its decided frequency. The present invention also relates to a corresponding method for a second coordinator, a first and a second coordinator, a system comprising at least a first and a second coordinator, and a corresponding computer program.
