Communicating anytime, anywhere...
Creating networks that connect everyone and everything

Wireless IC tags will be a key technology of the coming ubiquitous networking era. They will be used in a variety of applications, including automatic wireless data exchange, product information display while shopping, and even automatic payments. To help usher in the age of anytime, anywhere communications, we are creating leading-edge optical and mobile network technologies and developing comprehensive IC tag solutions.

We are developing optical transmission and photonic networking technologies for accelerating broadband communications and enabling high-capacity applications such as IPTV and telepresence. Our research on advanced photonic includes, 40 to 100 Gbit/s optical transmission technology for ultra high-speed backbone, optical pluggable modules for high performance with low cost system, and packet transport technology for efficient and reliable network with expanding research frontier from pure optics/photonics to higher layer.

GPS has been installed on various devices such as mobile phones, and various types of services using location information have been made possible. GPS, however, is still difficult to use in indoor environments. To expand implementation of these services, there is high demand for a precise means of measuring positions of people and objects both indoors and outdoors. Against this backdrop, we are developing a high-precision radio positioning system using ultra wideband (UWB) radio technology.

We are advancing research into next-generation web services that weave together desired information from the Internet and deliver it to users, for example, RSS(Rich Site Summary) systems that provide summary notifications to users when websites of interest have added new information. We are also developing services that quickly and accurately extract information tailored to the user's interests from the vast amount of content generated by blogs.

The ability to instantly extract desired information from wireless IC (RFID(Radio Frequency Identification)) tags is giving rise to a host of enhanced applications, such as improving the efficiency of merchandise management and logistics activities. In particular, UHF-band(Ultra-high frequency band) RFID tags, which are capable of reading and writing from a distance of several meters, will enable new services, such as the ability to simultaneously read data from multiple tags.
