Toshiba Corp. will showcase a reference display of an SDHC memory card with TransferJet close proximity wireless transfer technology at the 2013 International Consumer Electronics Show in early January, 2013.
The SDHC memory card on reference display will be a product under development, integrating a TransferJet transceiver IC, a coupler, an RF filter, peripheral passive parts, an SD bridge connection circuit, and Toshiba's NAND flash memory. Data transfer by TransferJet communications will be implemented in devices supporting SDHC memory cards, such as digital cameras and PCs, by inserting this card in the card slots.
TransferJet’s physical layer transmission rate is 560Mb/s, and even allowing for error corrections and protocol overheads, the effective physical layer transmission rate is 375Mb/s. 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. Unfortunately, communication distance of TransferJet is just three centimeters.
TransferJet does not need complex setup for operating. Directly touching two compliant electronic products together allows files to be transferred automatically, without the need for an access point. For example, 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 across all consumer electronics devices.
