Socionext Agrees with MIRAIT, MMD, and Nuri Telecom on Next-generation Long-distance Power Line Communications for Verification and Social Implementation

Launching Next-Generation Long-Distance Power Line Communications for Smart Connected Systems

Langen/Germany, 9. March, 2021 --- 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 by Socionext, 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 the international 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 is essential 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 under development is expected to play a role in smart connected systems that maximize the advantages of HD-PLC.

The four companies conducted a long-distance test verification using a compact PoC for system verification 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 enable communication 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 and other community development projects (Energy Management System, signage and cameras), and NURI 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” of communication through open innovation, thus contributing to the sustainable society.

Multi-hop function: 
Communication using multi-stage relay technology utilizing multiple HD-PLC communication devices
This compact PoC for system verification will be available in April 2021. Mass production of the LSI is scheduled to start during fiscal year 2021 (April 2021 - March 2022).
