The document discusses RAN evolution for 5G networks and virtualized RAN (vRAN) solutions. It notes that vRAN uses software applications on open market hardware to virtualize network elements, except the radio. This allows functions like the centralized unit and distributed unit to be deployed as software. The summary discusses how vRAN enables operators to create 5G "hotspots" through virtualization, open standards and interfaces, and an emerging OpenRAN ecosystem. It notes that vRAN is an edge application that allows 5G hotspots and moving the core network to the edge provides significant cost savings for operators facing declining revenues.
