Optical wireless communication system

Hokkaido Univ. Technology :The most Advanced Analog RoF technology of Beyond 5G (6G) : HK24-009

High-precision control of radio signals with simple configuration

　In order to increase the transmission capacity in wireless communication, the use of high frequency bands is being promoted, and it is required to reduce the load of signal processing in the base station. Specifically, the transition from digital optical wireless technology to analog radio-over-fiber (RoF) technology is being studied. However, in A-RoF, it is difficult to control the phase of radio waves in the base station, so MIMO (Multiple Input Multiple Output) signal processing also needs to be performed in the aggregation station. However, in the conventional A-RoF communication system, there is a problem that it is necessary to accurately control the phase of the A-RoF signal for each antenna element.　　According to the present invention, it has become possible to provide a MIMO signal processing device and an optical wireless communication system that enable MIMO signal processing for beamforming that accurately controls the phase of the A-RoF signal that enable MIMO signal processing for multi-beamforming that accurately controls the phase of the A-RoF signal with monochromatic optical carrier wave.

It excels in places where LAN cables are not suitable and in locations where a temporary network is needed!

The "optical wireless communication system" is a wireless communication technology that transmits data by modulating information onto light emitted from sources such as LEDs. By rapidly blinking the light at a speed that is imperceptible to the human eye (over 100 million times per second), it is possible to achieve stable wireless communication at a speed of 100 Mbps. Since it does not use radio waves, it is unaffected by interference from radio waves, allowing for wireless communication even in locations where traditional wired communication or radio-based wireless communication is difficult to secure. 【Features】 ■ Ensures communication even in locations where wired communication is challenging ■ Easy installation and relocation (cost reduction in installation expenses) ■ High communication quality due to immunity from radio interference and electromagnetic wave effects ■ High confidentiality due to secure one-to-one communication ■ Exempt from radio law regulations, eliminating communication costs ■ Ultra-low latency (below 10 μsec) *For more details, please refer to the PDF document or feel free to contact us.
