Over the past several decades, the need for wireless communication has increased dramatically. Worldwide deployment of fifth-generation (5G) communications, which has many more capabilities than fourth-generation communications, is likely to begin. Faster system capacity, higher data rate, lower latency, higher security, and enhanced quality of service (QoS) compared to the 5G system are some basic concerns that need to be solved beyond 5G. This article outlines the network architecture and future of 6G wireless communication. This article discusses cutting-edge technologies, including artificial intelligence, wireless optical technology, free-space optical networks, block chain, three-dimensional networking, quantum communications, unmanned aerial vehicles, cell-free communications, integrated access-backhaul networks, dynamic network slicing, holographic beam forming, and backscatter. In addition, potential technologies and anticipated applications with 6G communication needs are outlined. We also discuss potential obstacles to success as well as future research possibilities.
