HD-PLC

HD-PLC (short for High Definition Power Line Communication) is the technology standard of wired communication using high frequency band over wired medium including powerlines, phone lines, twisted-pair, and coaxial cables. It is the IEEE 1901-based standard.

Specification and features

There are essentially two different types of HD-PLC: HD-PLC Complete and HD-PLC Multi-hop. They are incompatible.

HD-PLC Complete[1]

This is for high speed applications such as TV, AV, and surveillance camera.

The major technical features include:

  • IEEE 1901 full compliant
  • QoS by the priority control
  • CSMA/CA and DVTP(Dynamic Virtual Token Passing) supported
  • Concurrent multi-AV stream, VoIP, and file transfer and file transfer supported using IP packet classification
  • Multi-network access at priority CSMA/CA with network synchronization

HD-PLC Multi-hop[2]

This is for long-distance applications such as smart meter, building network, factory, energy management, and IoT devices.

The major technical features include:

  • ITU-T G.9905 multihop technology

Common features
  • Uplinking/downlinking through 432 of 26MHz (between 1.8 MHz and 28MHz) bandwidth subcarriers with Wavelet OFDM
  • Maximum 240 Mbps PHY rate
  • Multilevel modulation for each subcarrier which suits the properties of the power line transmission channel and allows for the best transmission speed
  • Subcarrier masking with the arbitrary number which can comply with the rules in each country
  • Forward error correction (FEC) which enables effective frame transmission
  • Channel estimation launch system with change detector for cycle and transmission channel
  • HD-PLC network bridging compatible to Ethernet address system
  • Advanced encryption with 128 bit AES

Use cases

HD-PLC brings four main values for customers: upgrade to higher speed over the existing wireline, cost reduction of network construction using existing wireline, Complement the area where it is difficult for radio waves to penetrate, and wire saving.

Typical use case include:

Vendors

IP core vendor

Panasonic started to provide HD-PLC Complete and HD-PLC Multihop license.[9][10]

Chipset vendors

On June 23rd, 2020, as a part of the HD-PLC Alliance webinar, MegaChips, Shanghai Clouder Semiconductor, and Avalent technologies were introduced.[11]

Module vendors

Xingtera[12] and Mitsumi Electric[13] provides the modules.

Evaluation/Development Kit vendors

MegaChips provides evaluation and software development kit.[14] LonMark International adopted HD-PLC In 2017 after that Gesytec started to provide HD-PLC evaluation kit with LON extension from January 2018.[15]
