Sony today announced "TransferJet", a new Close Proximity Wireless Transfer Technology enabling the high speed transfer of large data files between electronic devices such as mobile phones, digital cameras, digital video cameras, computers and TVs.

Using this technology, data can be sent at speeds of 560Mbps. Sony will present reference exhibits of this newly developed technology at CES International.

TransferJet is a simple wireless technology which eliminates the need for complex setup and operation. For example, just touching a TV with a digital camera enables photos to be instantaneously displayed on the TV screen. TransferJet can be used as a Universal Interface among a wide variety of consumer electronics devices.

Sony will actively promote the use of TransferJet across the consumer electronics industry through the introduction of various products and services based on this technology.

TransferJet's physical layer transmission rate is 560Mbps, and even allowing for error corrections and protocol overheads, the effective physical layer transmission rate is 375Mbps. TransferJet is also capable of selecting the appropriate data transmission rate according to the wireless environment. Even if the conditions for transmission deteriorate, it will maintain the highest possible wireless connectivity by automatically lowering the data transmission rate. As TransferJet is a close proximity wireless system which radiates very low-intensity radio waves, it causes almost no interference to other wireless systems, and there is no impact to performance even if multiple users simultaneously multiple TransferJet system. Moreover, users of electronic products incorporating TransferJet technology are able to transfer data among each other's products regardless of whether they are indoors or outdoors and irrespective of their geographic location.

Sony's newly developed "TransferJet Coupler" is based on electric induction field coupling to deliver high propagation performance compared to conventional radiation field based antennas. It maintains high transmission gain and efficient coupling in near-field proximity, while providing sharp attenuation over longer distances to avoid interference with other wireless systems.

Furthermore, as there is no antenna polarization it is possible to transmit data without any performance loss, regardless of the contact angle of the electronic devices.
