As thinking of wireless technology, major solutions are remote controls, celler, bluetooth and WiFi. But there are so other solutions that, while fewer in number, are still necessary. Our one of the challenge is exploring them one by one. We forcase in the design, development, and quality control of wireless devices, including our main product, engine starters, as well as wireless control devices for security, medical, and industrial applications (industrial remote controls, telecontrols). We also have a local subsidiary in Munich, Germany, to serve as our sales base, where we design and develop wireless devices in compliance with the radio laws of various countries, such as Europe (CE maring), and introduce our products to markets around the world.
