A Survey on Future Millimeter-Wave Communication Applications

Millimeter-wave communications (mmWave) are gaining significant attention for their diverse applications across various domains, being key for the development of ultra-fast, low-latency wireless systems. This paper surveys the main application use cases where mmWave technologies can be adopted, focusing not only on scenarios where they are used for communication purposes, but also on other applications such as imaging and sensing. Each use case is described and characterized in order to provide a general overview of the foreseen mmWave application scenarios. The document also surveys existing standardization activities regarding mmWave frequencies across several application areas and discusses recent works regarding mmWave propagation, including both channel modeling as well as electromagnetic field exposure assessment and dosimetry, in different application domains. The document serves as a reference for a quick overview of all use cases where mmWave will have a practical impact.
