Close Proximity Wireless Transfer Technology from Sony.
Sony recently announced "TransferJet", a new Close Proximity Wireless Transfer Technology enabling the high speed transfer of large data files (photos, HD images, etc.) between electronic devices such as mobile phones, digital cameras, digital video cameras, computers and TVs.
But when
Sony say close proximity they mean close proximity as the distance between the two devices must be less than 3cm.
Which is why Sony has called one of the features "Touch & Get", where you just touch two electronic products together and files are transferred automatically. TransferJet eliminates the complex setup procedures required by existing wireless systems, and no access point is necessary.
Using this technology, data can be sent at speeds of up to 560Mbps. 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.
TransferJet is an extremely 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. Alternatively, downloaded music content can be easily enjoyed by touching a mobile phone to a portable audio player. TransferJet can be used as a Universal Interface among a wide variety of consumer electronics devices.
