As a key technology for next-generation cellular and Wi-Fi networks, millimeter-wave (mmWave) communication can achieve multi-Gbps wireless data rate and can support a broad class of new applications from communications to localization, sensing, and imaging. The IEEE DySPAN 2019 Workshop on mmWave Communications and Networks will bring together researchers from academia and industry to present and discuss novel ideas on the design, optimization, and implementation of mmWave communication networks and systems.
