Never one to settle for an open standard when the opportunity to push a proprietary alternative presents itself, Sony has announced that it will wade into the next-generation short-range interconnect wars with a proprietary new wireless spec called “TransferJet.” Sony’s proposed TransferJet spec has a physical peak transmission rate of 560Mbps and would appear to compete directly with short- and medium-range ultrawideband-based offerings like wireless USB (W-USB) and the next generation of Bluetooth technology. But in spite of any similarities to either W-USB or Bluetooth 3.0, both of which are based on the same WiMedia radio technology and promise transfer speeds in the 480Mbps range, Sony’s TransferJet has some distinguishing characteristics that set it apart from the pack.
In Sony’s vision of the future, any two consumer devices will be able to exchange data wirelessly with one another simply by holding them close together. The system is designed for maximum ease of use, which means limited options for controlling the transfers; devices will transfer their contents automatically to another device within range. Users can “register” devices within the home to keep them from transmitting to “unregistered” devices, which should keep Uncle Dave from beaming his “art photos” onto your TV set without permission. Other than that, everything else appears to be automatic and button-free.
