Touch-transfer technology will complement NFC, says Toshiba
Toshiba says its advanced RF-CMOS integration technology has enabled incorporation of an RF circuit and RF switch for TransferJet in a wireless IC for the first time in the industry. The new product achieves receiving sensitivity of -78dBm, surpassing the requirements of the TransferJet specification.
Using its 65nm process, Toshiba has reduced the chip size and decreased the number of external RF circuits and peripheral components required. The company claims this makes the new product particularly well-suited for increasingly compact and lightweight digital products, such as smartphones, tablet PCs, notebook PCs, and digital cameras.
The spread of mobile products is spurring demand for simple yet high-speed ways of sharing large image, video, and audio data among individuals, says Toshiba. It is addressing this demand by supporting the close proximity wireless transfer technology that allows data transfer simply by selecting on the screen of a mobile device the data file to be transferred and “touching” the receiving device with the mobile device.
TransferJet is a close proximity wireless transfer technology standard promoted by the TransferJet Consortium whose membership consists of 53 companies (as of September 2011), including Toshiba. TransferJet has a maximum specified transmission rate of 560 Mbit/s and maximum effective rate of 375 Mbit/s.
The application of TransferJet technology is expected to expanded with the growth of digital signage and through linkage with NFC (Near Field Communications) technology.
