Communication Technology

While explaining the technical features, applicability, and latest trends of millimeter wave (mmWave), we will also provide information on the synergistic effects of using mmWave in combination with local 5G (Private 5G), which has a high affinity with mmWave, use cases and introduction scenarios, and available solutions. The presentation will also discuss the approach to terahertz wave (6G), which is expected to be used in the next generation.
