What Is Nessum WIRE?
Transform any existing wires into communication lines
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.

Advantages Of Nessum WIRE In PLC Technology
The table below shows the types of PLC technology. There are three types: Narrowband PLC, Midband PLC, and Broadband PLC, and there is a trade-off between communication distance and communication speed.
Nessum WIRE is a broadband PLC technology. Its greatest advantage is "Flexibility". Nessum's unique signal processing technology makes it possible to change the frequency band used flexibly. This means you can choose "Long-range" or "High-speed" depending on your use case. Especially in long-range applications, Multi-hop technology contributes to increasing effectiveness.
