Who has the best 5G infrastructure?

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.

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

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.
