5G also uses wider bandwidth technologies such as sub-6 GHz and mmWave . Like 4G LTE, 5G OFDM operates based on the same mobile networking principles. However, the new 5G NR air interface can further enhance OFDM to deliver a much higher degree of flexibility and scalability.

Until network carriers are able to build out the independent infrastructure needed for 5G, the NSA approach uses a combination of 5G Radio Access Network (RAN), 5G NR interface, and existing LTE infrastructure and core network to provide a 5G-like experience.

South Korea, China, and the United States are the countries that lead the world in building and deploying 5G technology.

The companies best positioned to take advantage of the 5G growth include Ericsson, Nokia, and Qualcomm .
