A new technology platform for the future. In the super-smart society of the future, it is expected that various objects and people will be connected by IoT and wireless communications, and our company will strengthen research and development for wireless communications.
mm-Wave Wireless Communication Technology
In the fifth-generation (5G) mobile communications system, which will be the future information and communications infrastructure, high-speed, high-capacity wireless communication services using extremely high frequencies (Approximately 30 GHz or higher), called "millimeter wave (mm-wave)", will become widespread. Since mm-wave signals are easily attenuated and degraded compared to conventional microwave (Several GHz or less) signals due to various factors, advanced technologies and innovative ideas are required to design and manufacture mm-wave communication devices.
Our company is conducting R & D to improve the performance and lower the cost of the mm-wave communications devices. We have developed a 70 GHz band bandpass filter that achieves the world's best level of low loss, steep bandpass characteristics and compactness by employing a post wall waveguide (PWW) on a silica glass substrate. We have succeeded in developing not only individual components but also an integrated functional module, i.e., a 60 GHz band phased array communication module that achieves ultra-wideband (57 ~ 71 GHz), high output power (EIRP: 40 dBm), and wide beam scan range by integrating a planar antenna and a radio-frequency (RF) IC on a multilayer liquid crystal polymer (LCP) substrate. Its performance has been demonstrated in outdoor environments.

IoT Wireless Communication Technology
The Sensor and System Research Department is developing a dye-sensitized solar cell (DSSC). It can generate electricity with high conversion efficiency even in low illumination areas where ordinary solar cells cannot generate enough power. DSSCis a solar cell that is ideal for stand-alone power generation of sensor node used in a variety of situations, because it can generate electricity even under fluorescent lights and LEDs, and in northward or shady environments where direct sunlight cannot be obtained.
Our sensor nodes built-in 5 sensor - Temperature/Humidity/Illuminance/Atmosphere/Humanity (for indoor sensor node only) - employing this DSSCas a power supply and the 920 MHz unlicensed-band multihop radio module that has a high obstacle avoidance performance.
We won the IoT Technology Award at the ET&IoT Technology 2017 exhibition owing to those features. In April this year, we added LoRaWAN™ models as a new product family. Its LPWA technology covers long range up to 1 to 10 kilometers.
In the future, we will aim to expand applicable business areas by developing additional sensors and provide highly-value-added one-stop solutions integrating those sensors with data storage, visualization, and analysis by developing cloud services and applications.
