184. 5G NEW RADIO (5G NR) - AIR INTERFACE IN 5G MOBILE NETWORKS
The fifth generation of mobile networks promises a scalable platform that can effectively provide coexistence between existing services and future 5G services. 5G networks, despite connecting people, will provide interconnection and control between machines, objects and devices. In other words it is an innovation platform that can provide new services, enhance the user experience and connect new industries. The design of 5G not only focuses on improving mobile broadband, but also on providing control over services through ultra-reliable communication links with low latency and connection to massive internet services. At the heart of 5G network there is a new, unified radio interface - 5G New Radio (NR). 5G NR is part of the 3GPP standards defined in Release 15. This paper provides an overview of the specifications defined for standardization of the new generation of mobile networks, describes the key technologies that are subject for analysis about the development of 5G NR and gives a performance evaluation in order to make a comparison with the services we use today. This technology will start a new industrial revolution, providing high communication speeds, extremely low latency, reliable communication and services that have not been possible before.
