IEEE 1901

IEEE 1901

The HD-PLC technology is fully conformant with IEEE 1901 including Inter-System Protocol (ISP) coexistence. The IEEE 1901 Standard, ratified in 2010, was the first global standard for powerline communication developed for applications such as multimedia home networking, audio video, and smart grid. It has been amended in IEEE 1901a-2019 with enhancements of the HD-PLC physical layer (wavelet) for Internet of Things applications and has been revised in 2020 (IEEE 1901-2020).

Presentation

Sponsored by the IEEE Communications Society, this globally recognized BPL standard is designed for use in a wide range of applications including smart energy, transportation and Local Area Networks (LANs) in both residential homes and enterprise.

IEEE 1901 introduces sophisticated modulation techniques that are similar to what is used in WiFi and Wavelet Orthogonal Frequency Division Multiplexing algorithms. These innovations overcome traditional BPL technical concerns, such as RF noise generated in power lines, regional discrepancies in voltages and other power-transmission characteristics around the world, and the complexities of transmitting data through transformers.

Two technologies are implemented in the IEEE 1901 Standard. One is the HD-PLC technology based on a wavelet modulation the second one is based on FFT modulation. IEEE 1901 specifies a mandatory mechanism that allows coexistence both between those two technologies and between BPL and other technologies. The IEEE 1901 Inter-System Protocol prevents interference when the different BPL implementations are operated within close proximity of one another. The IEEE 1901 ISP also has been extended to International Telecommunication Union’s family of home networking standards ITU-T G.hn (ITU-T G.9972) and has been approved and required by the U.S. National Institute of Standards Technology’s as coexistence mechanism for broadband power line communications.

HD-PLC Implementation

HD-PLC IEEE 1901-compliant networking products deliver high-performance, interference-free and secure data transmission in excess of 500 Mbps in LAN applications even when multiple BPL technologies are connected to the same wire and range of up to 1,500 meters for first-mile/last-mile services.

Market Implications

Effectively transforming any conventional electrical outlet into a networking node, the products support a range of compelling applications, among them:

  • high-definition video streaming,
  • Internet Protocol gaming,
  • expanded data communications,
  • simplified image and sound distribution,
  • enhanced home security and enterprise services such as home automation, digital signage and triple-play communications

IEEE 1901a-2019

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.

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.

ITU-T G.9905

ITU-T G.9905

HD-PLC supports ITUT Recommendation G.9905, a robust and low-overhead multi-hop routing protocol that enables large scale HD-PLC networks.

Presentation

Recommendation ITU-T G.9905 specifies centralized metric based source routing (CMSR), a proactive, layer 2 multi-hop routing protocol. CMSR is a proactive routing protocol which can find and maintain reliable routes considering the link quality of both directions. The routing control packet overhead of CMSR is quite low compared to existing proactive routing protocols such as optimized link state routing (OLSR), so that it can be applied for large-scale networks even on narrow band power line communication (PLC) networks.

HD-PLC Implementation

At the heart of HD-PLC is an innovative Centralized Matrix-based Source Routing (CMSR) scheme, as defined in the ITU G.9905 international standard. This multi-hop functionality dramatically increases network range, robustness, speed, and simplicity.

Thanks to this advancement, HD-PLC is able to support over 1000 nodes, distances up to 10 kilometers, along with the advanced security protections required in today’s connected world.

HD-PLC supports up to 10 hops, enabling system integrators to expand networks to up to 1024 nodes. In this case, throughput is reduced (10Mbps, min), but system integrators gain the ability to quickly deploy large systems without time-consuming network planning or costly devices like switches and routers.

Multi-hop technology takes the guesswork out of network planning and design by enabling any node to act as a repeater. With this technology, the nodes in the network dynamically calculate route cost and select the best route based on link quality. This eliminates bottlenecks and improves robustness, since the network will automatically reroute traffic if any given node fails.

Multi-hop technology also brings the benefits of mesh networking to wired networks. System integrators no longer need to spend days planning and configuring their control networks. With HD-PLC, they can simply plug in their devices and let the network take care of the rest, automatically calculating route cost and dynamically optimizing traffic.

Market Implications 

Tomorrow’s smart city and smart building networks will be IP-based. IP connectivity enables system integrators to bring together the many islands of automation that exist among today’s building automation systems. It also facilitates the integration of operational networks with information networks, enabling project owners to fully harness the power of the Cloud and Big Data.

An IP-based protocol, HD-PLC meets the demands of tomorrow’s applications with an integrated network bridge functionality that enables any terminal to act as a bridge between PLC networks and Ethernet and serial networks. This makes network design and integration easy—and eliminates costly gateway devices, complicated wiring, and complex software development.

ANSI/CTA 709.8 LON HD-PLC

ANSI/CTA 709.8 LON HD-PLC

In 2017 LonMark International adopted HD-PLC as the new channel standard for high-speed wireline networks. Using IP-based communications HD-PLC provides LON systems with an instant speed upgrade- from just kilobits to megabits-without needing to add or replace wiring.

The new standard ANSI/CTA 709.8 LON HD-PLC (High Definition Power Line Communication) was approved In February 2020 as a new American National Standard (ANS) by the American National Standards Institute (ANSI) standards.

Presentation

The new LON HD-PLC standard enables native LON communication over any IP transport such as Ethernet and Wi-Fi, as well as interoperability with IP-based web services so that building and industrial automation systems can seamlessly and securely interoperate with cloud and IoT applications.

LON HD-PLC platform implements an Ethernet-like transmission, wherein devices act as an Ethernet gateway in parallel, enabling double use for all IP-based solutions. It creates a single control system to aggregate data and detects hidden faults in HVAC operations. Plus, IP networks can be used as a native network medium for LonWorks, so the use of LonWorks/IP-only devices is also possible.

HD-PLC Implementation

Using IP-based communications (IPv4 or IPv6 multicasting), HD-PLC provides LON systems with an instant speed upgrade- from just kilobits to megabits-without needing to add or replace wiring. Especially designed for building automation, IPv6 provides a cost-effective transport mechanism for complex control systems to communicate with devices.

Compared to the conventional low-speed PLC, HD-PLC enables high-speed communication and can cover a range of several kilometers with the multi-hop function. Thus, it can increase the speed and the coverage of conventional LonMark compatible systems. In addition, it can reduce the need for new communication wiring work by using existing lines such as double wires, twisted pairs, coaxial cables, and telephone lines, as well as power lines.

Market Implications

With this transformative wireline communication technology, manufacturers can effectively build a robust infrastructure into buildings today, ensuring the future-readiness for intelligent HVAC of tomorrow.

It is expected that high-speed communication LonMark compatible systems will replace conventional LonMark in indoor equipment controls of buildings and factories and outdoor equipment controls such as smart street lighting and lighting systems that use double-wire communication.
