Wireless network operators in four countries -- the United States, Japan, South Korea and China -- are largely driving the FIRST 5G build outs. Network operators are expected to spend billions of dollars on 5G capital expenses through 2030, according to Technology Business Research Inc., although it is not clear how 5G services will generate a return on that investment. Evolving use cases and business MODELS that take advantage of 5G's benefits could address operators' revenue concerns.
