Wireless communication systems, such as cellular phones, have offered mobile voice/mail services to us. Nowadays, they begin to offer mobile internet services which handle high capacity photo/motion data. In order to enjoy freedom from wired lines, small size, light weight, long battery life terminals have been required. For the next generation wireless systems which include terrestrial / satellite communications, dependable connectivity and green wireless information technologies (IT) will be the key issues.
Advanced Wireless Information Technology(Prof. Suematsu)
Toward the realization of a ubiquitous and broad-band wireless network, we are actively engaged in the research work on dependable and low power consumption advanced wireless IT. We cover the whole technical fields from the lower to higher layers, i.e., signal processing, RF/Mixed signal device, antenna, MODEM and network technologies.
As the studies on signal processing, RF/Mixed signal device and antenna technologies, we are developing RF/Millimeter-wave RF CMOS IC’s, antenna integrated 3-dimensional system in package (SiP) transceiver modules, digital/RF mixed signal IC’s.
As the studies on MODEM and network technologies, we are focusing on next generation mobile broadband wireless access (MBWA: mobile broadband wireless access), dependable broadband wireless local area network (WLAN) and ultra-broadband wireless personal area network (WPAN).
We are also working for the next generation wireless communication systems/devices which include a location / short message communication system via quasi-zenith satellites (QZS) and a fusion of various wireless communication systems “dependable wireless system.”
- Broadband wireless on-chip transceivers
- Millimeter-wave/submillimeter-wave IC’s
- Low power digital signal processing for multi-mode wireless / satellite communications
- Location and short message communication system via QZSS
- Wireless system/devices for intra-body communication
Advanced Wireless Network Technology(Assoc. Prof. Kameda)
We are engaged in the development of wireless access technology for heterogeneous wireless network include satellite communications. Specifically, we are developing seamless roaming technologies among heterogeneous networks and large-capacity wireless access method for large disaster relief.
