6G Mobile Communications Systems: Requirements, Specifications, Challenges, Applications, and Technologies

The Fifth Generation (5G) Wireless networks were planned to be free from the limitations of previous generations. It has become necessary for society to move beyond 5G and design a new architecture that can incorporate the technological needs of both the individual and society. Therefore, if Sixth Generation (6G) mobile communications are to be developed, many aspects must be improved, the most evident being: latency, higher data rate, quality of service (QoS) and system capacity. When looking at the previously mentioned aspiration and requirements of future networks, the need for the development of 6G networks becomes clear. Nevertheless, many challenges which society must overcome for such networks to be implemented exist. The cost of solving such problems pales in comparison to the potential benefits of 6G networks. This paper discusses the challenges of implementing 6G networks.
