In one aspect, the method of synchronising a communications device in a wireless communications network comprises receiving a beacon signal at a first frequency; and receiving a data signal at a second frequency, the beacon signal being used to synchronise reception of the data signal. In another aspect, the method comprises transmitting a beacon signal at a first frequency and transmitting a data signal at a second frequency, the beacon signal being useable to synchronise reception of the data signal. The first frequency is substantially less than the second frequency such that the beacon signal experiences substantially different frequency-dependent propagation effects to the data signal.
