Introduction To Nessum - What Is "Nessum"?


Nessum is compatible with the international standard IEEE 1901 series and is capable of long-range wired communication and near-field high-speed wireless communication using any media such as wired, wireless, and underwater. Furthermore, hybrid communication between wired and wireless can be achieved with a single device.

With Nessum WIRE for wired communication and Nessum AIR for near-field wireless communication, this technology will solve various problems in network construction and realize an IoT society where everything is connected.

What is Nessum WIRE?

Nessum WIRE

Transform any existing wires into communication lines

There is wiring used for various purposes inside and outside buildings, such as dedicated lines, coaxial lines, and power lines.
Nessum WIRE allows these existing wiring to be used as is for communication. There is no need for new wiring of communication cables, making it possible to construct a network in a short construction period and at a low cost.


Technical features of Nessum WIRE

long distance

Communication can be established over a few km

Even in large facilities such as buildings and factories, as well as with smart meters, the multi-hop technology that relays multiple subunits enables communication over a few km*.

*The communication distance varies by use environment.

shielded spaces

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.

simple and low cost

A network can be built at a lower cost

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.

speed up

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.

high security

Available in areas where wireless
communication is prohibited

High security is ensured by establishing a physical wired connection, encrypting transmitted data, and completing optimal cryptographic 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.

reduction of lines

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.

What is Nessum AIR?

Nessum AIR

Enhance the communication speed while maintaining precise control of the communication range

In the case of e-mobility power management systems, multiple vehicles are placed in close proximity, which can lead to false vehicle detection and security issues due to radio wave interference.
Nessum AIR enables high-speed communication while accurately limiting the communication range by adjusting the transmission power and antenna size and shape. It also reduces radio wave interference with neighboring devices and achieves high security.


Technical features of Nessum AIR

high security

The communication distance can be controlled
between a few and 100cm​

By controlling the transmission distance based on the transmission power and the 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.

reduction of lines

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.

Hybrid wired and wireless communication

Nessum uses the same technology for wired and wireless communications, making it easy to create hybrid configurations. Since both can be covered with one communication device, it can be realized at a low cost.

As an example, if we assume that factories will become smarter, by using existing twisted pair wires and power lines and building a network with Nessum WIRE, it will be possible to control equipment, collect operational data, and remotely monitor with network cameras. In addition, by connecting the transfer robots (AGV) moving within the factory and the charging dock with Nessum AIR, and connecting the charging dockside to the core network via Nessum WIRE, charging control and positioning detection of a large number of transfer robots will be possible.

This technology is expected to be widely used through wired and wireless hybrid networks.
