Internet of Things (IoT) Compatibility and Network Equipment Usage Accelerated in Building Management and Smart Street Lighting
HD-PLC Alliance*1 announced today that the LonMark standard adopting High-definition Power Line Communication (HD-PLC )*2 was approved by ANSI*3 as American National Standard (ANS), ANSI/CTA 709.8 LON HD-PLC . (For announcements by CTA*4 and LonMark International Inc.*5 , please visit the web page at https://www.lonmark.org/hdplc_press_release/).
So far, the power line communication method used in the LonMark standard was low-speed power line communication (“low-speed PLC”; maximum speed is about several kbps). This was no more compatible with the requirements for IoT and the current demand for various network devices connections.
Therefore, in 2017, LonMark International adopted HD-PLC , enabling communication at tens of mbps, as one of its communication methods and promoted it for standardization at ANSI/CTA. Standard has now been approved.
Compared to the conventional low-speed PLC, HD-PLC enables high-speed communication and can cover a range of several kilometers with the multi-hop function. Thus, it can increase the speed and the coverage of conventional LonMark compatible systems. In addition, it can reduce the need for new communication wiring work by using existing lines such as double wires, twisted pairs, coaxial cables, and telephone lines, as well as power lines. Thus, it is expected that high-speed communication LonMark compatible systems will replace conventional LonMark in indoor equipment controls of buildings and factories and outdoor equipment controls such as smart street lighting and lighting systems*6 that use double-wire communication.
The HD-PLC Alliance began collaborating with LONMARK JAPAN*7 last year. Simultaneously, we are working on revising a part of the HD-PLC communication compatibility certification test according to the standardization of the HD-PLC system. In addition, we have newly added an HD-PLC communication compatible certification for coaxial and double-wire compatible devices to support the expansion of the market with these compatible devices.
The HD-PLC Alliance will continuously work with LonMark and other industrial standards setting organizations to improve the environment for communication compatibility certification. In addition, we will keep contributing toward establishing universal standards and promoting wider use of HD-PLC compatible products with the motto “HD-PLC faces up to challenges in becoming the IoT solution that connects people’s living, industry, and the community.”
