TransferJet is a close proximity wireless transfer technology initially proposed by Sony and demonstrated publicly in early 2008.
The concept of TransferJet consists of a touch-activated interface which can be applied for applications requiring high-speed data transfer between two devices in a peer-to-peer mode without the need for external physical connectors.
The functional elements of a generic TransferJet Coupler consist of a coupling electrode or plate, a resonant stub and ground.
Compared to conventional radiating antennas, the TransferJet Coupler achieves higher transmission gain and more efficient coupling in the near-field while providing sharp attenuation at longer distances.
π/2-shift BPSK Although sometimes confused with Near Field Communication, TransferJet depends on an entirely different technology and is also generally targeted for different usage scenarios focusing on high-speed data transfer.
[5] TransferJet, NFC and wireless power are the three major near-field (contact-less) technologies that are expected to eliminate the physical connections and cables currently required to interface devices with each other.
This specification uses the 60 GHz band and requires only 2 msec or less to establish a connection prior to the actual data transfer, thereby enabling the exchange of large content files even in the short amount of time it takes, for example, for a person to walk through a wicket gate.
