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.

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. 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 to ensure mutual connectivity with IEEE P1901 Series products, and continue to supply PLC products that users can use with confidence.
