Panasonic Holdings Corporation / Nessum Department List of Products and Services

When introducing IoT, do you have any of the following concerns? ● You want to use stable and secure wired communication, but the cost of LAN cable wiring is high. ● You tried to build a wireless network, but there are areas where the signal does not reach. Our next-generation wired communication technology (Nessum WIRE) can help solve these issues. This technology allows you to utilize existing lines (power lines, control lines, coaxial cables, etc.) as communication lines, enabling network construction without the need to lay new LAN cables. 【Use Cases】 ■ Utilizing existing power lines in apartment complexes, factories, and stations to build networks with short construction periods and low costs. ■ Building networks in areas where wireless signals do not reach, such as underground parking lots and tunnels, without extensive construction. Additionally, there are examples of utilizing lines other than power lines, such as spare lines in factories and existing coaxial cables. We have a catalog available with details of the case studies and an overview of the technology. You can also view various products tailored to your needs through the related links. If you have any questions, please feel free to contact us.

• LAN construction and wiring work

Nessum WIRE (formerly HD-PLC) is a next-generation wired communication technology that adheres to the IEEE 1901 international standard. This innovative technology transforms existing infrastructure, allowing diverse lines—including power lines, control lines, and coaxial cables—to function as communication paths. This eliminates the need for new communication line installations (like LAN cables), significantly reducing network deployment costs. 【Features】 ■ Low Cost: Utilization of existing metal lines ■ High Speed: Effective speeds (UDP/TCP) from several Mbps to several tens of Mbps ■ Long Distance: Multi-hop communication over several kilometers ■ Secure: Data encryption (AES128), compatible with IEEE 802.1X ■ Reduced Wiring: Reduction of internal wiring in devices such as robots ■ Wireless Complement: Network construction in areas where wireless signals are difficult to reach If you are interested in products equipped with this technology, please refer to the related links.

• Communications

When introducing IoT, do you have any of the following concerns? ● Wireless signals may interfere, causing communication to drop ● Signals may reach too far, resulting in unintended devices connecting ● There are security concerns with wireless communication Nessum AIR can help address these issues. Our proprietary Wavelet OFDM technology controls the communication range (transmission power) and frequency to reduce radio interference with adjacent devices and avoid unintended connections. Additionally, by limiting the communication range to a short distance, secure communication is possible. Furthermore, since Wavelet OFDM was originally developed for wired communication, it allows for easy construction of networks that combine wired and wireless connections. 【Usage Examples】 ■ Charging control for e-Mobility devices such as EVs, e-Scooters, and robots ■ Location detection for parking spaces and charging spots of the same e-Mobility devices ■ Wireless conversion of internal wiring in devices (replacing slip rings in cameras and industrial robots) We have a catalog available that outlines the technology and usage examples.

• Communications

Nessum AIR (formerly PaWalet Link) is a near-field wireless communication technology that applies Wavelet OFDM technology, which is one of the wired communication technologies, to wireless communication. It utilizes a magnetic field for communication and limits the range by employing a loop antenna. Since it allows for both wired and wireless communication using the same technology, hybrid networks that combine both can be easily constructed. Furthermore, by utilizing multi-hop technology, it is also possible to expand to large-scale networks. 【Features of Wireless Communication】 ■ It uses a communication method based on magnetic fields, and the communication range (from a few mm to several tens of cm) is limited by transmission power and antenna shape (aperture area). ■ When combined with Wireless Power Transfer (WPT), it enables not only high-speed communication but also WPT control and position detection. 【Features of Hybrid Communication (Wireless/Wired)】 ■ By using functions such as OFDM modulation/demodulation, error correction, and encryption, it theoretically achieves a maximum effective speed in the hundreds of Mbps range. ■ Various modes/channels allow for application in a wide range of usage scenarios.
