LONDON – The TransferJet Consortium is due to demonstrate close proximity wireless transfers at data rates that are more than 1,000 times faster than near field communications (NFC) at the Mobile World Congress being held in Barcelona, Feb. 25 to 28.
At the event accessory products and prototypes – USB adapters, SD and SDIO cards – from Sony and Toshiba will be shown working with commercial smartphones and tablets. The consortium also plans to demonstrate a content download service from kiosk machines whereby smartphone and tablet users can download movies, music, e-books and so-on using TransferJet add-ons.
Chips, components, and modules that support TransferJet and available for design-in will also be on show, the consortium said.
TransferJet is a low-power, proximity data transfer technology designed to deliver a transfer data rate of up to 560-Mbits per second using a radio carrier center frequency of typically 4.48-GHz.

The TransferJet Consortium includes Sony, Hitachi, JVC Kenwood, Nikon, Olympus, Panasonic, Pioneer, Seiko Epson and Toshiba as "promoter members" and more than 30 adopter members.
The TransferJet Consortium was established in 2008 and registered as a Japanese incorporated association in 2011.

"... using a radio carrier center frequency of typically 4.48-MHz."
4.48GHz!

My mistake.
Thanks for pointing it out.
I have corrected it in copy.

Yeah, definitely not 4.48 MHz.
This broadband NFC is a useful concept these days. And it should be considerably easier to achieve than an equivalent channel capacity over, say, WiFi. For one thing, NFC devices don't have to share the frequency channel with multiple client devices at the same time!
Interesting graphic. In truth, though, WiFi includes the distances shown for PAN. I'm quite sure that my WiFi printer is not more than 1 meter away from my WiFi access point!

TransferJet is another perfect of how ignorant the Japanese are. The Japanese OEMs are wasting their already thinning finance and resources to build a standards which does not really benefit the real-world applications!
As Bert and many engineers have pointed out now and before, existing technologies like 802.11 offer extension which can cover the purpose. However, for the sake of being different and to leverage at what they are still strong at (i.e. DSLR, DSC, multi-function printer, etc.), the Japanese OEMs are ganging together to tempt the non-Japanese OEMs. I hope none of the Taiwanese/American/European are stupid enough to follow. Let the Japanese OEMs waste their money, if they so choose. The rest should just stand by and watch the Japanese OEMs deplete their hard-earned money in the bank!

In battery powered applications, that require security, the TransferJet is a much more valid choice to transfer large amounts of data. As long as the two device can be situated within an inch of each other.
