IEEE 1901a-2019

IEEE 1901a, BPL communication standard for IoT, enables to control HD-PLC frequency bands according to usage. It allows scalable communications with features to extend communication distances and to select speeds. The flexible features defined in this standard enable to address the diverse communication needs of IoT-related services.

HD-PLC Implementation

IEEE 1901a standard adds the following new features to the Panasonic original HD-PLC Wavelet OFDM technology (standard mode) adopted in the IEEE 1901-2010 standard.

  • The standard mode communication band can be doubled or quadrupled, allowing a 500 Mbps communication speed in double mode or a maximum of 1 Gbps in quadruple mode on coaxial cable or dedicated line.
  • The standard mode communication band can be compressed by a factor of two or four (half or quarter), concentrating energy in narrow bands and consequently extending the communication distance up to twice the distance in standard mode with a lower communication speed.
Flexible Channel Physical Layer

Market Implications

This ability to select communication speed modes allows a flexible response to each user’s needs, opening the scope of HD-PLC application to all aspects of daily life.

In order to continuously offer new lifestyle values according to the needs of the residents, every product such as household equipment, consumer electronics, and sensors in a home must always be connected to networks. The newly approved IoT BPL communication international standard defines a foundation technology designed for communications in homes, but not only. This technology also supports large-scale networks covering social infrastructure such as buildings and factories as well as homes, with prospects for use in a wide range of areas.
