Company / Press Release
The World’s first*1 Communication technology enabling wired, wireless, and undersea communication through a single device
Osaka, Japan – Panasonic Holdings Corporation (hereinafter referred to as "the Company") today announced that the Company's technology based on its Wavelet OFDM*2 scheme was approved in August as Draft 1.0 of IEEE P1901c*3 by the working group under the IEEE Standards Association*4 in which the Company participates. This next-generation communication standard allows the same modulation and demodulation method to be used via various communication media, including wired, wireless, and underwater communication. It was developed as a form of communication to contribute to the realization of IoT Society. With this approval, the Company will change the brand name for the communication technology from HD-PLC*5 to Nessum*6 and accelerate its global business development.
The next-generation communication standard, for which the Company's technology has been approved as the draft standard, extends the frequencies to be used for wired communication from the conventional megahertz range to the kilohertz range, enabling even longer distance communication over a variety of communication media. In addition, the application of this technology to wireless communication that uses an antenna and very weak radio waves will make it possible to achieve secure short-distance and high-speed wireless communication that can limit the communication range*7. The technology also contributes to the realization of IoT communication under the sea, which was previously considered difficult*8. The application of this technology to undersea and underwater IoT has been adopted in the Beyond 5G R&D Promotion Project of the National Institute of Information and Communications Technology (NICT), titled "Research and development of wireless communication technology for undersea and underwater IoT (No. 02301),"*9 which is undergoing technological development and demonstration experiments.
Up to now, the Company has used this technology for wired communication under the brand name of “HD-PLC (High Definition Power Line Communication)”. It was originally named in 2000 to express its aim of providing high-definition video transmission along home mains power lines. However, the technology is now adopted also in buildings and factories beyond video transmissions and can also employ coaxial and exclusive lines in addition to power lines. Furthermore, the technology is now being utilized for near-field and high-speed wireless communication for smart factories and undersea/underwater IoT. Because advances in technology have led it to be used in more areas than initially envisaged, the Company takes this timing of approval of draft standard to change the brand name to Nessum to brand this globally.
If it is adopted as an IEEE international standard in the future, it is expected to be further applied in various fields around the world; thereby contributing to the reduction of the overall introduction cost of IoT devices. As with HD-PLC, the Company will utilize Nessum in Panasonic Group's products and services, and also license the technology to other companies to encourage its broader use. Examination of the potential for wider utilization of the Nessum brand has already started in the HD-PLC Alliance*10, which the Company established in 2007. The Company will continuously work with the 24 member companies of the alliance to establish this technology as an international standard, expedite compatibility certification, and promote its use in an expanding range of applications.
*1: The world's first communications technology and international standard that enables wired (using power lines or control lines), wireless, and undersea communications using a common modulation and demodulation scheme.
*2: Wavelet OFDM: The term "wavelet" refers to the function of a localized wave (a wave of finite length that rapidly decays) and is used for frequency analysis by applying wavelet transformation to the data. A type of discrete wavelet conversion is utilized in OFDM to achieve this technology.
*3: A new project approved and established by the IEEE Standards Association in May 2022
*4: The standards committee that formulates communication standards under IEEE (the Institute of Electrical and Electronics Engineers)
*5: HD-PLC is the name of a high-speed power line communication format proposed by the Panasonic Group and is a registered trademark or trademark in Japan and other countries. PLC is the initialism for Power Line Communication.
*6: "nessum" and its logo are trademarks of Panasonic Holdings Corporation in Japan and other countries.
*7: Near-field, high-speed communication technology based on Wavelet OFDM was released as PaWalet Link technology on November 10, 2021.
*8: Wireless optical communication and wireless acoustic communication were conventionally developed as undersea IoT communication technologies. Although wireless optical communication enables high-speed communication, problems are encountered if used in light-absorbing environments such as the deep sea. On the other hand, while wireless acoustic communication enables long-distance transmission, it tends to be slow.
*9: Undersea IoT communication technology is a technical theme promoted by the National Institute of Information and Communications Technology (NICT)'s Beyond 5G R&D Promotion Project and is being jointly developed with the Kyushu Institute of Technology.
*10: The organization was established on September 25, 2007, with the aim of expanding the adoption of HD-PLC high-speed power line communication technology, ensuring communication compatibility between products that make use of communications technology, and promoting international standardization activities.
