【MIRAIT Corporation】
Socionext Agrees with MIRAIT, MMD and Nuri Telecom on
Next-generation Long-distance Power Line Communications forVerification and Social Implementation
Launching Next-Generation Long-Distance Power Line Communicationsfor Smart Connected Systems

MIRAIT Corporation, MMD inc., NURI Telecom Co.,Ltd and Socionext Inc. have agreed that the four
companies will jointly conduct a test verification using a compact PoC system equipped with
next-generation long-distance power line communication LSI, currently being developed bySocionext, world's leading fabless SoC suppliers. The companies will proceed with specific studies
for social implementation mainly in the energy and ICT fields.
HD-PLC (High Definition Power Line Communication) is a technology that complies with theinternational standard IEEE 1901-2020 to put communication signals on power lines, unlike ordinary
communication networks, wired or wireless. Its greatest feature is that it eliminates the need for
dedicated communication networks for individual devices by utilizing the power lines and realizes
communication between devices while consolidating the signals into power lines. The
next-generation long-distance power line communication LSI that Socionext is developing now
complies with the next generation standard of high-speed power line communication, and achieves
industry-leading small size, low power consumption, and long-distance communication, by
Socionext's proprietary low power solution, high-performance analog, and power supply
technologies with using advanced process technology. Establishing communication network isessential for digital transformation (DX), which is to reduce labors through remote and automatic
control of various information devices using technologies such as IoT and AI and realize more
comfortable lives. The next generation long-distance power line communication LSI underdevelopment is expected to play a role in smart connected systems that maximize the advantagesof HD-PLC.
The four companies conducted a long-distance test verification using a compact PoC for systemverification of the next-generation long-distance power line communication LSI, and obtained
communication verification results for a distance of over 1 km. It is expected to enablecommunication for a total distance of 10 km with the multi-hop function (*1). MIRAIT's network
integration for building communication infrastructure, MMD's solutions for aquariums, museums andother community development projects (Energy Management System, signage and cameras), andNURI Telecom's sensor and energy solutions, are among the focus applications.

The four companies will move into the validating phase for the use of the next-generation
long-distance power line communication LSI, and provide new solution for “last one yard” ofcommunication through open innovation, thus contributing to the sustainable society.

Communication using multi-stage relay technology utilizing multiple HD-PLC communication devices

MIRAIT Corporation
Using the technology and knowledge of communication infrastructure construction bytelecommunications carriers, MIRAIT will begin designing and constructing a communication
network that takes advantage of the next-generation HD-PLC for bidirectional communication forcollecting data of equipment such as power receiving facilities, air conditioning and power
generation facilities, and various information devices such as meter and sensors, and will promote
its implementation in society.
