The Hunt for high- Frequency Spectrum

Infrastructura Costs and Deployment Economics

Cost- Reduction Strategies: Infrastructura Sharing and Cloudification

To lower total cost of ownership, the industry is puching for open and virtualized; RAN architectures (O-RAN) that decoupla hardware from swware, enabling operators to use commercial off-the- shelf servers and share infrastructure across multiple tenants. 6G is predicted to bo ba fully cloud- native, with core and RAN functions runng as micservices on sped code.
