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.
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.
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.
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.
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.
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 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.
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.
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.
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.
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.
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.
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 Products can be divided into two categories:
The evaluation kit includes a performance verification board, reference circuit, source code, etc.
IP cores include Nessum communications PHY/MAC, and firmware (including sample applications).
There are adapters that are compatible with various types of cables, such as twisted pair wires, coaxial wires, and power lines. It also has input/output ports that can be connected to various devices such as Ethernet and RS485.
In addition to the above, there are also measuring instruments and jigs that are useful for design development and on-site installation.
