5G Mobile Networks: Requirements, Enabling Technologies, and Research Activities 55
2.6 Conclusion
The number of ever‐increasing number of connected devices, the emergence of new
services, and the increase of communication needs from vertical industries require the
development of a next generation mobile system, 5G. Although 5G is still under the
research and development process, it will most likely be ready for the users by 2020. In
the 5G system, there will be a variety of advanced technologies, such as massive MIMO,
Cloud‐RAN, SDN, NFV, etc., as well as the usage of unoccupied frequency bands above
6 GHz. In addition, the 5G network infrastructure will be constructed as multiple slices
by adopting the network slicing technology. These technologies promise to fulfill the
requirements, which come from both the user perspective and the networking perspective, in order to serve a large number of use cases in 5G era.
This chapter presents the visions and main use‐case classes, key requirements, and
enabling technologies for 5G. The chapter also summarizes the status of ongoing activities
related to 5G development from all over the world, including standardization organizations as well as regional research communities. In the remaining chapters, potential
security related problems in future 5G networks will be analyzed and discussed.
