Optimizing fronthaul connectivity in Cloud RAN is best achieved using Ethernet technology due to its ability to provide high bandwidth and low latency, essential for the communication between the centralized baseband processing and distributed radio units. Ethernet supports various bandwidth options and is widely deployed in both traditional and modern network architectures, making it a flexible solution for scaling networks according to demand.

Moreover, Ethernet is designed to handle packet-switching, which is crucial for the efficient transfer of the diverse data types used in RAN environments. Its extensive implementation also means there are established standards and protocols that can be leveraged to ensure interoperability and reliability in communication links across different vendors and equipment types.

While fiber optic technology does provide substantial bandwidth and low latency, it often serves as the physical medium for Ethernet connections, making Ethernet the more suitable choice at the technology level for optimizing fronthaul. Wi-Fi and satellite communication, while useful in their respective contexts, do not meet the stringent requirements for performance and reliability demanded in fronthaul applications.
