Downlink transmission performance under local 5G outdoor base station installation and 4K high-definition real-time video transmission experiment utilizing them

In an environment where a local 5G wireless base station is installed on the roof of a university research building, the transmission characteristics of synchronous TDD and downlink data channel 4×4 MIMO transmission are evaluated in comparison with SISO transmission. Then, we evaluated the 4K real-time video transmission performance and clarified its basic characteristics.
