Abstract: The present invention relates to a wireless network 30; 60 including at least two subnets 31-34; 61-63. Each subnet comprises a plurality of units 21, 22 configured to wirelessly communicate with each other. The wireless network is configured to select a local set of communication parameters CP1, CP3 for internal communication within each subnet in such a way that internal communication within neighboring subnets uses different local sets of communication parameters to prevent interference between neighboring subnets, and to select at least one common set of communication parameters CP2 for each subnet to be used when communicating between subnets in the wireless network 30; 60. The invention also relates to a method for adapting a wireless network, a method for forming a wireless network and a communication unit.

Abstract: The present invention relates to a method for selecting operating frequency channels having frequency parameters, such as a frequency interval or at least one carrier frequency, for a network communicating data over a shared medium. The network is configured to communicate within a frequency range, and the frequency range is divided into a plurality of frequency channels f1-fn, each frequency channel defines a predetermined frequency parameter. The data to be communicated over the network is divided into sequences FS, each sequence having a plurality of positions SP1-SPm. The method further comprises regularly scanning the frequency range to identify interfering frequencies generated by interfering networks operating within said shared medium, and assigning a frequency channel fk to each position SPi within the sequences FS based on the identified interfering frequencies, whereby the use of interfering frequencies is limited.
