Millimeter wave wireless communication is expected to be used in 5G because of the high-speed communication, but the problem is that communication distance is limited due to large attenuation of radio waves. An international team of researchers (Japan, USA – industry) has developed a video transmission system with a millimeter wave wireless communication device that uses a small, lightweight lens antenna that can be mounted on a drone. In tests, the team was able to use a drone to take video in 4K and transmit the video in real time from over 100 m in the air to an access point on the ground. Delay using the system is also dramatically reduced compared to conventional compressed transmission…read more.
