ABSTRACT
Recently, the majority of the countries have announced deployment of the fifth-generation (5G) wireless communication in a variety of application areas. In the meanwhile, few academic institutions and industries have allocated funds to start the intense research and take on the challenge of the sixth generation (6G). Specifically, this study reviews the progress of the wireless generations and the advancement of the important millimeter-wave (mmWave) applications in the face of 5G communications. The main focus of this paper is based on the study of mmWave technology, its advantages and disadvantages, followed by the predominant applications used in different mmWave bands. Moreover, the investigation has mainly focused on radar systems, radio communication, radiometry, atmospheric sensing, and satellite imagery. MmWave applications are playing an important role in 5G communication. It has a great opportunity to embark on such applications in the upcoming 6G communication. However, there is still room for fundamental improvements on the radio and the network to form new applications.
