Research and development are progressing toward ubiquitous network in the 21st century's wireless information technology. The ubiquitous network immediately provides any information for everyone at anytime and anywhere.

For realizing the ubiquitous network, we are interested in developing following wireless networks;

(1) next-generation mobile broadband wireless access (MBWA), (2) dependable broadband wireless local area network (WLAN), and (3) ultra-broadband wireless personal area network (WPAN).

We are also actively engaged in work on following technology for broadband, low-power consumption and small-size terminals; (1) RF power amplifier, synthesizer and mixer devices for millimeter wave and GHz-band wireless modems, (2) Ultra small antennas for mobile terminals. Moreover, seamless interconnection technology using 3-dementional system in package (3-D SiP) has been investigated.

Currently, we are concentrating on the coherent work toward the next-generation "Dependable wireless next generation network (NGN) terminal" which enables signal-demodulation of any band and any type received radio wave.
