5G mobile systems challenges and technologies: A survey

The huge increase of the data traffic was exited the borne of 5th Generation (5G) mobile communication system looking at 10 Gbps data rate and around 1ms latency. As the cellular data demand increasing, the actual 3 GHz spectrum band becoming so crowded. This leads to look for a new allocated mobile communication frequency bands that can offer a broadband amount of spectrum. In 5G mobile system the ultra-wide millimeter wave (mmWave) spectrum will be adopted. mmWave frequency band starting from 30 GHz to 300 GHz, constitutes a substantial portion of the unused frequency spectrum, which is an important resource for future wireless communication systems in order to fulfill the exponential demand of capacity. In this paper, we provide a survey on the mm-Wave frequency band general characteristics and its main challenges; we also state the required technologies that were necessary for making 5G system as a real and efficient solution.
