High-speed and secure short-range wireless communication technology - Nessum AIR
Utilizing wired communication technology for wireless! By controlling the range and frequency of communication, we reduce radio interference and achieve secure communication.
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.
