  • A Survey on Millimeter-Wave for 5G Mobile Systems
  • The dramatic growth of mobile data services driven by wireless Internet and smart devices has triggered the investigation of 5G Mobile system for the next generation communication system. 5G will be inter the market in the year of 2020. As the mobile data demand grows, the actual sub-3 GHz spectrum band becoming increasingly crowded. In 5G mobile system the ultra-wide millimeter wave (mmWave) spectrum will be adopted. A mmWave frequency band which its range between 30 GHz to 300 GHz comprises a substantial part of the unused frequency spectrum. That is definitely a fundamental resource for future wireless communication systems to be able to meet the rising capacity demand. In this paper, we provide a survey on the mmWave frequency band general characteristics and its challenges, we also determine the main required technologies that were necessary for making 5G system as a reality.
