The term "fronthaul" specifically refers to the connection between the Remote Radio Heads (RRHs) and the Central Unit (CU) in a Cloud RAN architecture. This connection is crucial, as it handles the transport of radio signals and associated data over the network. In Cloud RAN, the architecture is designed to separate the radio processing functions from the baseband processing functions, enabling more flexible and scalable network deployments.

Fronthaul connections facilitate the transmission of digitized radio signals from the RRHs to the CU, where they undergo processing. This setup allows for centralized management of radio resources, improved performance, and lower latency, which are critical for modern telecommunications networks.

The distinction of fronthaul from other types of connections clarifies its importance in the overall architecture. For instance, options focusing on user devices or server connections address different components of network architecture entirely and do not accurately capture the function of fronthaul in the specific context of Cloud RAN.
