ABSTRACT:
The present invention relates to a method and arrangement in an ad-hoc network for synchronizing a multiple of radio transceiver arrangements with different characteristics that make use of a common air interface. Each transceiver arrangement comprises at least two transceivers which mutually communicate via a radio transmission link. All transceivers synchronize to a common synchronization signal comprising two staggered beacon pulse series signals (TX.sub.1, TX.sub.2) which have the same repetition rate. The transceivers synchronize their internal timers which control the signal transmission from the transceivers, to the strongest one of the two beacon pulse series signals (TX.sub.1, TX.sub.2) by listening during one of the corresponding sets of time windows (RX.sub.1, RX.sub.2). Between the reception of two beacon pulses, each transceiver transmits beacon pulses itself, thus contributing to the generation of the other beacon pulse series signal, on which other transceivers can lock.
