3GPP Releases 15, 16, and beyond

What is 5G NR?

5G is the fifth-generation cellular network technology. The industry organization for standardization 3GPP defines any radio using the 5G NR (5G New Radio) software as 5G. 5G NR follows 2G, 3G, 4G, and their respective associated technologies GSM, UMTS, LTE, and LTE Advanced.

A 5G Base Station uses New Radio (NR) technology is referred to as gNodeB (gNB). gNodeB radios feature Software Defined Radio (SDR) with various MIMO options including 2x2, 4x4, 8x8, and Massive MIMO options for higher capacities. 5G NR can support up to million devices per square kilometer while 4G LTE supports only up to 100,000 devices per square kilometer
