Revolutionizing Wireless Communication: NEC Achieves Japan's Longest Terrestrial Wireless Optical Communication

NEC Corporation has successfully demonstrated Japan's longest terrestrial wireless optical communication, a free-space optical (FSO) communication technology, over a distance of more than 10 km.

This achievement is a significant milestone in the development of FSO technology, which has the potential to revolutionize wireless communication.

FSO communication transmits and receives light beams without using physical paths, such as optical fibers, making it a promising technology for future wireless communication systems.

FSO technology has several advantages, including high directionality, low risk of interception, reduced interference and congestion in communication, and no need for radio wave usage permits.

NEC has developed a capture and tracking technology that enables automatic capture and tracking of bidirectional optical beams, helping to overcome challenges such as atmospheric turbulence.

The company has also developed long-distance optical communication technology used in satellites, highlighting the potential of FSO technology to be used in various fields.

The successful demonstration was conducted between a pair of FSO communication devices located more than 10 km apart in Nasushiobara City, Tochigi Prefecture.

This achievement marks a significant step forward in the development of FSO technology, which has the potential to be used in various applications, including telecommunications and disaster relief.

FSO technology can be used to provide high-speed data transmission over long distances, making it a promising technology for future wireless communication systems.

This breakthrough could lead to the development of new wireless communication technologies that are more secure, efficient, and reliable than existing technologies.
