IEEE 1901
IEEE 1901 is a standard for high-speed (up to 500 Mbit/s at the physical layer) communication devices via electric power lines, often called broadband over power lines (BPL). The standard uses transmission frequencies below 100 MHz. This standard is usable by all classes of BPL devices, including BPL devices used for the connection (<1500m to the premises) to Internet access services as well as BPL devices used within buildings for local area networks, smart energy applications, transportation platforms (vehicle), and other data distribution applications (<100m between devices).
The IEEE 1901 Standard, established in 2010, set the first worldwide benchmark for powerline communication tailored for multimedia home networks, audio-video, and the smart grid. This standard underwent an amendment in IEEE 1901a-2019, introducing improvements to the HD-PLC physical layer (wavelet) for Internet of Things (IoT) applications. It was further updated in 2020, known as IEEE 1901-2020.
The IEEE 1901 standard replaced a dozen previous powerline specifications. It includes a mandatory coexistence Inter-System Protocol (ISP). The IEEE 1901 ISP prevents interference when the different BPL implementations are operated within close proximity of one another. To handle multiple devices attempting to use the line at the same time, IEEE 1901 supports TDMA, but CSMA/CA (also used in WiFi) is most commonly implemented by devices sold.
The IEEE 1901 standard is mandatory to initiate SAE J1772 electric vehicle DC charging (AC uses PWM) and the sole powerline protocol for IEEE 1905.1 heterogeneous networking. It was highly recommended in the IEEE P1909.1 smart grid standards because those are primarily for control of AC devices, which by definition always have AC power connections - thus no additional connections are required.
The IEEE 1901 Standard was a significant step in the development of powerline communication (PLC) technologies. PLC allows for data communication over existing power lines, which can be particularly useful in environments where it's difficult to lay new wiring or where wireless communication might be problematic.
The development and evolution of the IEEE 1901 standard underscores the importance of powerline communication in modern networking scenarios. As the IoT continues to grow, with billions of devices getting connected, having a robust and versatile communication medium like PLC can be invaluable, especially in environments where traditional networking methods might be challenging.
The IEEE P1901 Working Group started in June 2005. More than 90 organizations contributed to the standard. Half of the organizations were from US, a quarter from Japan and the last quarter from Europe.
IEEE 1901 completed a formal standard IEEE 1901-2010 published in December 2010. The working group which maintains and extends the standards is sponsored by the IEEE Power Line Communication Standard Committee (PLCSC). IEEE 1901-2020 has been published in January 2021.
