The vital communication standard,which bridges the gaps in an IoT society and brings people's lives and industries to the next level.
Toward the realization of an IoT society where everything will be connected via networks, the HD-PLC communication standard has been relaunched under the new brand name Nessum. Nessum will achieve smart operations in areas once considered difficult due to a variety of issues such as network construction costs and security requirements. It will bridge the gaps in an IoT society and enrich people's lives and industries in every corner of the world.
Nessum WIRE/AIR for both wired and wireless communications
Nessum is a communication technology consisting of Nessum WIRE, a wired communication technology,
and Nessum AIR, a short range wireless communication technology.
Support for both wired and wireless communication expands the area of usefulness.

Five areas where Nessum can make contributions
Nessum WIRE, which enables communication using existing wiring, can network HEMS as well as a growing number of home IoT devices, contributing to comfortable living and greater energy consumption efficiency.
Nessum WIRE, which enables communication using existing wiring, can network any type of equipment, including elevators, HVAC, and surveillance camera systems, thereby contributing to total building management.
Nessum WIRE enables long distance communication to build smart grids using renewable energy such as wind and solar. This will contribute to the establishment of smart operations for energy supply and demand within communities.
Frontline operations, including factories, underwater sites, and underground tunnels, where communication was deemed difficult, can now be networked through Nessum WIRE/AIR, thereby contributing to productivity and safety improvements.
The use of Nessum WIRE/AIR enables the networking of a variety of road infrastructures such as street lights, traffic lights, and guardrails, which will contribute to safe and smooth road traffic.

Nessum WIRE(wired communication technology) is a technology for updating existing lines as communication lines.
Nessum WIRE can use existing cables inside and outside the building, such as power lines as well as coaxial cables, twisted-pair cables, and telephone lines, as communication lines. A high-speed network can be readily built without laying new cables.
Example of existing lines that can be used
Nessum AIR (short range wireless communication technology)is a technology that improves communication speed while precisely limiting communication range.
Nessum AIR provides high-speed communication at speeds of up to 1 Gbps while controlling the communication range at an interval of a few to 100 cm based on the size and shape of the antenna and transmission power. This will contribute to areas where the detection of location information was deemed difficult.
Short range wireless communication mechanism
Why Nessum is chosen in a variety of sites
Nessum WIRE (wired communication technology)
Communication over a few km is possible
Even in large facilities such as buildings and factories, as well as with smart meters, the multihop function that relays multiple subunits enables communication over a few km*.
＊The communication distance varies by use environment.
Examples: Smart meters, smart buildings, factories, smart street lights, HVAC (heating, ventilation, and air-conditioning) systems, solar power systems
Connection is possible even in areas where wireless communication is difficult
In confined spaces such as tunnels and underground facilities, it is often difficult to receive wireless signals. Nessum WIRE uses existing lines and enables communication even in these locations.
Examples: Tunnels, underground facilities, elevators, RC buildings
A network can be built by using existing lines
The use of existing wiring (dedicated and power lines) saves the trouble of installing a new LAN cable. This will shorten the construction period and enable the establishment of a low-cost network.
Examples: Surveillance cameras in stores, factories, hospitals, etc., intercoms, nurse call systems
Mbps-based high-speed communication is possible
In preparation for the IoT era, there is a need to accelerate lines of communication such as RS485 Modbus, low-speed PLC, and HBS (IEBus).The introduction of Nessum WIRE will enable Mbps-based high-speed communication without changing these communication lines.
Examples: Smart meters, commercial air-conditioners, solar power systems
Available in areas where wireless communication is prohibited
High security is ensured by establishing a physical wired connection, encrypting transmitted data, and completing optimal modulation within 30 seconds. This will mitigate the risks of information leakages and cyberattacks. A network can be built in facilities where wireless communication is prohibited due to security issues.
Examples: Gas stations, plants prohibiting the use of wireless communication
The risk of disconnection can be mitigated and inspections simplified
By consolidating multiple control and signal lines, the number of wires can be reduced. This will mitigate the risk of disconnection, decrease the failure rate, reduce weight, reduce the manufacturing lead time, and shorten the duration of routine inspections for elevators, etc.
Examples: Elevators, robots
Nessum AIR (short range wireless communication technology)
The communication distance can be controlled between a few and 100cm
By controlling the transmission distance based on transmission power and antenna size/shape, the communication range can be controlled at an interval of a few to 100cm, creating a communication environment free from interference for a variety of settings.
Examples: Mobility power management systems
Data communication at speeds of up to 1 Gbps is possible
The high frequency efficiency Wavelet-OFDM improves the communication speed. The maximum speed is 1 Gbps* which can transmit low latency video streaming.
* This is the standard's theoretical value. The maximum supported speed varies depending on the product.
Examples: Transmission of in-plant surveillance footage
