The analyst defines 5G network infrastructure to include radio access networks (RAN), transport networks, and core networks (which may include one or more edge networks). 5G introduces many disruptive technologies, from new chips and devices to new network architectures, that impact all areas of network infrastructure. The promise of 5G for consumers and enterprise is huge, as is the impact to communications service providers (CSPs) and their suppliers. Growth opportunities abound. The 5G core and edge networks are now entirely cloud-based. The 5G RAN is moving to the cloud and beginning to explore open interfaces, which introduces potential new suppliers to the market. The 5G transport networks tie together the RAN, the edge, and the core. Functions from the core network and from the RAN network are moving to edge networks to reduce latency and enable new use cases.
