Samsung has joined a new industry group to support Sony’s close proximity wireless data transfer format called TransferJet:
TransferJet is aimed only at very short distances. It operates in the 4.5 GHz frequency range and can send data at physical-layer rates up to 560 Mbits/s over distances of up to just 1.25-inch. It uses a direct-sequence spread spectrum modulation technique in which the transmitted signal takes up more bandwidth than the information signal that is being modulated.
Sony pitched the technology as an alternative to other UWB efforts that face difficulties getting approval to use spectrum in various countries worldwide.
