What is 5G New Radio | What is 5G NR | 5G New Radio Features

This page describes basic features of 5G NR i.e. 5G New Radio technology. It mentions 5G new radio (5G NR) standard and radio network related information.

What is 5G New Radio (5G NR):
It is the evolution to LTE Advanced and LTE Advanced Pro wireless technologies. It supports diverse spectrum, diverse services and diverse deployments. It provides major performance, cost and efficiency improvements from previous wireless technologies. Moreover it incorporates backward compatible enhancements to the next generation wireless devices. The 5G NR standard is published with release 15 and above.

5G technology handles 1000 times more traffic compare to 4G and at 10X faster speed. Five technologies are merged together to make 5G achieve these specifications. They are millimeter waves, small cell, massive MIMO, beamforming and full duplex.


Specification / Feature 5G New Radio support
