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.
A method of synchronizing a plurality of peer radio transceivers comprising the steps of:
A method of obtaining orthogonal radio channels in a network having multiple transceiver arrangements with each arrangement comprising at least two transceivers communicating via a radio link, said method comprising the steps of:
A synchronization apparatus comprising a plurality of transceiver arrangements each comprised of at least two peer transceivers communicating via a radio link wherein the transceiver arrangements use a common air interface and lock to one part of a common synchronization signal while contributing to at least one other part of said common synchronization signal, the common synchronization signal being formed by superposed beacon pulses.
A method for synchronizing a transceiver arrangement in a radio network wherein the transceiver arrangement comprises at least two transceivers communicating via a radio link and each transceiver comprises an internal timer, said method comprising:
A method for synchronizing a transceiver arrangement in a radio network wherein the arrangement comprises at least two transceivers communicating via a radio link and each transceiver comprises an internal timer, the method comprising:
