5G NR (New Radio) is a new Radio Access Technology (RAT) developed by 3GPP for the 5G mobile networks. In this course you will have an in-depth understanding about 5G Radio Access Network (RAN) based upon the 3rd Generation Partnership Project (3GPP) standard and specifications.
The 5G New Radio standards developed by 3GPP is intended to significantly improve the performance, flexibility, scalability and efficiency of mobile networks. In this way 5G was designed to be able to ensure the optimum use of the available spectrum, whether it is licensed, shared or unlicensed, and achieve this across a wide variety of spectrum bands. 5G New Radio is able to provide high bandwidth communication for the transmission of streaming services as well as low latency services.
