Frost & Sullivan defines 5G network infrastructure to include the following:

• Radio access networks (RAN)

• Transport networks

• 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 will impact all areas of network infrastructure. The promise of 5G for consumers and for enterprises is huge. The impact to communications service providers and their suppliers is equally large (in a good way). Growth opportunities abound.

The 5G core and edge networks are now entirely cloud-based, and the 5G RAN is quickly moving to the cloud. In addition, the industry is exploring open interfaces and new architectures for the 5G RAN (which Frost & Sullivan refers to as open and virtual RAN), enabling new suppliers to compete in the market. The 5G transport networks tie together the RAN, the edge, and the core and also is cloud-based.
