IEEE 1901 is a standard for high-speed communication devices via electric power lines. Developed by the Institute of Electrical and Electronics Engineers (IEEE), the standard is designed to support both Broadband Power Line Communications (BPL) and In-building Power Line Communications (IPLC).

Here are some key points about IEEE 1901:

Scope: IEEE 1901 covers frequencies below 100 MHz, which means it encapsulates both broadband and narrowband power line communications.

Data Rates: The standard can support data rates up to 500 Mbps, making it suitable for applications ranging from internet access to multimedia streaming within homes and businesses.

Applications:

  • Access BPL: Delivering broadband internet access over power lines, particularly in areas where traditional broadband infrastructure is unavailable or cost-prohibitive.
  • In-building BPL: Enabling local area networking within a home or business using the existing electrical wiring.

Modulation Techniques: IEEE 1901 includes several modulation techniques, including Wavelet OFDM (Orthogonal Frequency Division Multiplexing) and FFT OFDM, allowing for flexibility in different environments and conditions.

Interoperability: One of the goals of IEEE 1901 was to create a standard that ensures interoperability between different power line communication devices. This is crucial for broad adoption and usability.

Coexistence: The standard addresses the need for coexistence with other technologies and services, ensuring that devices don’t interfere with each other, even when operating on the same network.

Security: IEEE 1901 incorporates mechanisms for data encryption and secure communication, addressing potential concerns about eavesdropping or unauthorized data access over power lines.

Adoption: Many PLC devices that adhere to the HomePlug AV and HomePlug Green PHY specifications are compliant with IEEE 1901. This has helped establish a degree of standardization in the industry.

Benefits: By providing a standardized approach to power line communication, IEEE 1901 aids in the broader adoption of PLC technologies, making it easier for consumers and businesses to establish networks without the need for additional wiring.

IEEE 1901 represents an essential step in formalizing the technical specifications and performance criteria for power line communication technologies. It ensures that devices from different manufacturers can work together seamlessly and that users can enjoy reliable, high-speed communication over their existing electrical infrastructure.
