6G Wireless Communications Networks: A Comprehensive Survey

The commercial fifth-generation (5G) wireless communications networks have already been deployed with the aim of providing high data rates. However, rapid growth in number smart devices and emergence Internet Everything (IoE) applications, which require an ultra-reliable low-latency communication, will result a substantial burden on 5G networks. As such, rate that could be supplied by unlikely sustain enormous ongoing traffic explosion. This has motivated research into continuing to advance existing toward future generation cellular systems, known as sixth (6G). Therefore, it is essential provide prospective vision 6G key enabling technologies for realizing To this end, paper presents comprehensive review/survey evolution Specifically, objective about networks, include discussion main operation principles each technology, envisioned potential current state-of-the-art research, related technical challenges. Overall, provides useful information industries academic researchers discusses potentials opening up new directions.
