The key-value of 5G is that it is enabling advances in increased speed (10-100X Data Rates), lower latency, higher capacity (1000X more capacity) and it is delivering real-time communication. The initial  5G applications include automotive, mobile computing and networking, and Industrial IoT. Fleet management, freight, video surveillance, and tracking, are now using the 5G advances. As 5G solves more problems, more use cases unfold. But 5G is not a hard cut-over and is designed to coexist with 4G. Many industries will take time for technology maturity while others will utilize the new advances that 5G offers.
