HD-PLC 4 IP Core - High-speed Wired Communications Solutions for the IoT Era

Overview

Key Features

• The standard mode communication band (250 Mbps) can be doubled or quadrupled, allowing a 500 Mbps*4 communication speed in double mode or a maximum of 1 Gbps*4 in quadruple mode on coaxial cable or dedicated line.
• The standard mode communication band can be compressed on two levels (half or quarter), concentrating and extending the communication distance up to twice*5 the distance in standard mode.
• With the multi-hop function, it is possible to operate a wide area network of up to 1024 nodes.
• Communication bandwidth
• High-speed mode (1 Gbps, 500 Mbps) *Optional
• Standard mode (250 Mbps)
• Long-distance mode (2 x or 1.5 x the range of standard mode)
• Approved standards
• IEEE 1901-2020
• ITU-T G.9972 (Coexistence mechanism for different PLC systems)
• ITU-T G.9905 (Multi-hop) *Optional
• EN 50561-1:2013 (Dynamic notch and dynamic power control)

Benefits

• Provides high-speed wired communication
• As we move into the new IoT era, we need to speed up communication networks that are based on technology standards such as “RS485 Modbus,low-speed PLC, and HBS (IEBus). By adopting HD-PLC, high-speed communication at megabit speeds is possible without any new wiring.
• E.g. Smart meters, commercial air conditioners, solar power systems, etc.
• Low-cost network construction
• By utilizing existing wiring (dedicated lines and power lines), the need to install new ethernet cables is reduced. This makes it possible to build a network at low cost.
• E.g. Surveillance cameras in stores, factories, and hospitals, intercoms, nurse call systems, etc.
• Can be used in high-security locations
• In addition to encrypting communication data, HD-PLC offers high security by using optimal modulation for each sub-carrier in response to changes in transmission line characteristics. Therefore, the risk of information leaks or cyber-attacks is reduced. It can provide communication networks in facilities where wireless communication is prohibited due to security issues.
• E.g. Gas stations, plants where wireless signals are prohibited, etc.
• Less lines, less work
• By grouping multiple control and signal lines, HD-PLC can reduce the number of wires needed. This in turn lowers the risk of disconnection and line failure, in addition to reducing weight, shortening manufacturing lead time, and streamlining regular inspections of elevators and such.
• E.g. Elevators, robots, etc.
• Works in places where wireless communication can be difficult
• A drawback of wireless communication is that signals can be weak in enclosed spaces such as tunnels and underground facilities. With HD-PLC, communication can reach even those locations by leveraging the existing wiring.
• E.g. Tunnels, underground facilities, elevators, and reinforced concrete buildings, etc.
• Enables long-distance communication
• Even in the case of smart meters or large-scale facilities such as office buildings and factories, a wireless multi-hop network technology bridging together multiple devices can enable communication within a range of several to a dozen kilometers.
• E.g. Smart meters, smart buildings, factories, smart streetlights, HVAC, solar power systems, etc.
