Panasonic Corporation announced that it has presented its fourth-generation scalable HD-PLC (the name of a high-speed Power Line Communication (PLC) system created by Panasonic Corporation, and is a trademark or registered trademark in Japan and other countries) technology to IEEE Standardization Working Group (The standardization Working Group relating to Power Line communications standards under IEEE (Institute of Electrical and Electronics Engineers).
This technology enables communications over longer distances and improves communication speeds by controlling the range of frequencies in use. Following the Working Group's deliberations, specifications using this technology as the technical baseline have been approved as an IEEE P1901.3 Working Document.
The baseline technology included in the approved IEEE P1901.3 Working Document is based on the technology (standard mode) already adopted for the IEEE 1901 standard, using Panasonic's unique Wavelet OFDM format, but includes a new function (2x/4x modes) which broaden the communication band by a factor of two or four.
The 2x mode achieves a communication speed of 500 Mbps, while the 4x mode which requires coaxial wires or other specialist wires achieves a maximum communication speed of 1 Gbps (500 Mbps and 1 Gbps are theoretical maximum physical speeds).
The new function also enables to narrow the communication band by another factor of two or four (1/2x, 1/4x) from the standard mode. Narrowing the communication band reduces communication speed, but by concentrating energy into a narrow band frequency, communication distance can be lengthened by up to about two times compared to the standard mode (Maximum communication distance varies depending on communication environment conditions).
By enabling to switch between different modes, this technology can flexibly meet the specific needs of each individual customer, and bring HD-PLC technology to a broader range of uses.
The IEEE P1901.3 technology is labelled Internet of Things (IoT) PLC.
It can be used both in homes, and within large-scale networks covering everything from larger buildings and factories to entire social infrastructures.
It is anticipated that the technology will be used in a wide range of fields in future.
Panasonic will continue to provide user convenience by ensuring connectivity with existing HD-PLC products, and developing a PLC technology that can operate in harmony with other formats.
The company will also work through organizations such as the HD-PLC Alliance (Established on September 25, 2007 with the aim of ensuring communications compatibility and widespread adoption of HD-PLC high-speed Power Line Communication technology.
