The share of Optical Wireless Communication is increasing with the rapid proliferation of IoT. As a result, communication needs that cannot be covered with conventional wired and wireless communications are increasing at an explosive pace. The "Optical Wireless Communication" proposed by TAIYO YUDEN is able to provide one-to-one wireless communication at stable speeds (100 Mbps) using light. We created a form of wireless communication that works even in areas where it is difficult to implement communications using radio waves. This technology does not use radio waves and is unaffected by interference or noise.

Technical Information

Next-generation high-speed communication of "Optical Wireless Communication." The following is an easy-to-understand introduction which compares the differences between the high-speed communication technology based on the unique LEDs successfully developed by TAIYO YUDEN and other general communication methods.

Achieving high-speed communication through LEDs

The communication speed of Optical Wireless Communication using general-purpose LEDs is typically 10 Mbps or less. However, TAIYO YUDEN developed its own technology which increases the communication speed by approximately 10 times.

The upper limit for the modulation frequency of standard LEDs is about several MHz

When LED light is flashed at high speed (as many as 100 million times per second), the waveform distorts. Using its own unique technology, TAIYO YUDEN accelerated the speed by compensating for the waveform distortion which occurs at high speeds.
