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.
