HD-PLC Benefits – 5 Challenges that HD-PLC solves

HD-PLC is communication technology by using the existing cables. This technology can help you solve your challenges, such as below.

  • The speed of wired communication currently used is slow, which is an obstacle to the development of new products and services.
  • Ethernet cable installation cost is high when building a network
  • Searching for alternative technologies for HomePlug
  • Heavy cables and harness
  • Build a network in a place where the wireless does not reach or stable

The speed of wired communication currently used is slow, which is an obstacle to the development of new products and services.

Wired communication such as RS-485, Narrow-band PLC (G3-PLC and PRIME, etc), IEBus, HBS (Home Bus System) is still a very popular communication technology. These can communicate on the order of several hundred kbps. On the other hand, for the coming era of IoT and digital transformation, there is a demand to increase this communication speed to create new products and services. HD-PLC is the answer. It is possible to increase the speed from several Mbps to several tens of Mbps while using the same wiring as those.

Application examples

Building Automation, Smart Buildings, HVAC, Energy Management, Security camera, Smart factories, Intercom systems, Call button systems, etc.

Ethernet cable installation cost is high when building a network

In buildings and factories, IT such as data visualization, device control, automation, and camera installation is rapidly advancing. To do this, it is essential to build a network, but construction costs are high, such as installing ethernet cables under the floor or ceiling of a building, or installing HUBs every 100 m. HD-PLC is not as fast as Ethernet, but it can communicate at Mbps to tens of Mbps without wiring Ethernet cables. By applying HD-PLC where the requirements can be met at this speed, the cost of network construction can be reduced.

Application examples

Network building at factories, buildings, commercial facilities, streets, construction sites, tunnels, farms, etc.

Replacing analog cameras with digital cameras with existing coaxial cables

Searching for alternative technologies for HomePlug

HD-PLC is the same broadband PLC technology as HomePlug. It can communicate from several Mbps to several tens of Mbps. Besides, HD-PLC relay technology (multi-hop function) enables long-distance communication of several kilometers.

Heavy cables and harness

Various devices such as actuators and sensors are connected by cable to elevators, robots, vehicles, etc. If there are many cables, problems such as increased manufacturing lead time, increased failures, increased inspection man-hours, and increased mass occurs. Therefore, it is possible to save cables by collecting the signals exchanged via those lines using HD-PLC.

Build a network in a place where the wireless does not reach or stable

Wireless may be difficult to pass in underground equipment and buildings where metal or concrete is used for the wall material. When constructing a network there, it is common to install an ethernet cable, but the cost may increase due to the need for a HUB every 100 m and the wiring work under the floor or the ceiling. This problem can be solved by using HD-PLC and building a network using coaxial lines and power lines that already exist in the environment.

Conclusion

PLC has the following merits to solve the problems introduced so far.

  • High-speed communication is possible compared to the legacy communication method
  • Network construction at a low cost
  • Long-distance communication (several km) is possible even though it is a broadband PLC like HomePlug
  • Cable saving
  • Wireless complement
