Proximity Wireless Technologies for Mobile Phone
Updated: November 2011
By incorporating proximity wireless technologies developed in Japan, mobile phones have evolved into a smart, indispensable life tool. The Japanese mobile phone market has already implemented such a concept by equipping a contactless IC card technology "FeliCa" - one of the Near Field Communication (NFC) technologies - to be utilized in a variety of applications. The phone with FeliCa is called "Osaifu-Keitai" (mobile phones with wallet functions). "TransferJet" technology is another proximity wireless technology featuring simple operation and fast transfer of large data. It will be used for the transfer of large files and content streams such as video by simply touching two mobile devices together or between a device and a stationary equipment, such as a video terminal, signage, TV, PC, etc.
FeliCa
FeliCa is a contactless technology developed by Sony Corporation, which complies with NFC IP-1 standardized in ISO/IEC 18092. The solution of this high speed and secure contactless communication has been extensively deployed for electronic ticketing in public transportation and extended to offer a variety of applications such as electronic payment and security systems (Solutions of FeliCa). This successful introduction of FeliCa in the Japanese market becomes a useful reference of the NFC technology, which is gaining a lot of attention in the global market under the expectation of new service provisioning for mobile phones. The Japanese mobile phone is also expected to evolve by embracing the NFC standard which will fully realize NFC services in combination with existing FeliCa-based services.
TransferJet
TransferJet is a new type of close proximity wireless data transfer technology designed to transfer data quickly by just touching two devices together. This intuitive operation of TransferJet is realized by means of a peer-to-peer connectivity, which does not require complex security measures or setup procedures. Physical layer transmission rate is 560 Mbps and the maximum data throughput is 375Mbps. Only a few seconds are needed to transfer a one-hour TV program (e.g., 170MB in MPEG4) (TransferJet Overview).
The TransferJet Consortium, an incorporated association registered in Japan, was established in 2008 for the common goal of developing the technology, products and services based on TransferJet wireless technology.
