A method of mitigating interference between two or more wide body area networks WBANs, the method comprising: detecting, at a first WBAN, control channel beacons transmitted from one or more other WBANs, each control channel beacon specifying a data channel on which the respective WBAN is operating determining, based on the detected control channel beacons, whether one of the other WBANs is operating on the same data channel as the first WBAN and if so, adjusting one or more communication parameters of the first WBAN or requesting said one of the other WBANS to adjust its own communication parameters in order to mitigate interference between the first WBAN and said one of the other WBANs.
