Nessum WIRE is the wired communication technology that solves various problems in network construction and realizes an IoT society where everything is connected.
There is wiring used for various purposes inside and outside buildings, such as power lines, dedicated lines, coaxial lines, and twisted pair 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 networks in a short construction period and at a low cost.
In addition, this technology supports any network configurations, e.g., daisy chain, tree, and star connections, and it can convert traditional non-IP networks to IP networks.
Even in large facilities such as buildings and factories, as well as with smart meters, the multi-hop technology that relays multiple terminals enables communication over a few km.
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.
There is a need to speed up communication such as RS485 Modbus, low-speed PLC, and HBS (IEBus). The introduction of Nessum WIRE will enable Mbps-based communication without changing these existing lines.
High security is ensured by establishing a physical wired connection, encrypting transmitted data, and completing optimal cryptographic modulation. A network can be built in facilities where wireless is prohibited due to security issues.
By consolidating multiple control and signal lines, the number of wires can be reduced. This mitigates the risk of disconnection and contributes to decreasing the failure rate, reducing weight, reducing the manufacturing lead time, etc.
