How close to reality is 5G, the highly touted next-generation mobile networking infrastructure? Many providers are already touting trials of network services that employ limited 5G radio spectrum on top of 4G core networking infrastructure. Real-world applications running on fully implemented 5G networks should start appearing around 2020. It's why tech-savvy leaders at large enterprises are working 5G capabilities into their IT roadmaps, especially where cloud computing, Internet of Things (IoT), and machine learning/artificial intelligence fit into the 5G architecture. It's important to understand 5G's potential, and where it will intersect with your industry, business model, and processes, sooner rather than later.
