Advanced Wireless Communication Technology [Suematsu] Lab
Machine-translated · View original
A lab that studies circuits and systems for wireless communication linking the ground and satellites.
AboutAbout the lab
Wireless communication technology linking the ground and satellites.
The Advanced Wireless Communication Technology Lab studies technologies that make wireless communication, such as mobile phones, more reliable and lower in power consumption.
The lab aims to realize advanced information networks that integrate terrestrial and satellite systems.
It conducts consistent research and development, from hardware technologies such as signal processing circuits, devices, and packaging to wireless system technologies built on them.
The lab belongs to the Information and Communication Infrastructure Research Division of the Research Institute of Electrical Communication.
Key terms
- CMOS
- One way of fabricating semiconductor integrated circuits using silicon.
- Direct digital RF transceiver
- A transceiver that replaces analog circuits with digital circuits as much as possible. It also leads to smaller size and software-defined radio.
- Low Earth orbit (LEO) constellation
- A method of building a communication network by combining many satellites orbiting close to Earth.
- Sixth generation (6G)
- The next generation of mobile communication systems, used for mobile phones and other devices.
ResearchResearch themes
Wireless communication such as mobile phones needs high reliability, so that it stays connected anywhere, on the move, and during disasters, as well as low power consumption. Aiming to realize information networks that integrate terrestrial and satellite systems, the lab studies highly reliable, low-power wireless communication technologies.
*Illustrative imageWireless Hardware Technologies
The lab develops circuits such as power amplifiers, synthesizers, and mixers for very high-frequency bands using silicon CMOS technology, as well as ultra-small antenna modules. It focuses on direct digital RF transceivers, which replace analog circuits with digital circuits as much as possible.
*Illustrative imageSatellite Communication and 6G System Technologies
The lab studies next-generation, Japan-original low Earth orbit (LEO) constellation satellite communication systems and terrestrial sixth-generation (6G) distributed antenna systems.
