Simply put, front-haul is the link that connects the Baseband Unit (BBU) to the Remote Radio Head (RRH) which historically used a CPRI or OBSAI protocol over fiber. Network operators, seeking more capacity at a lower “cost-per-bit”, have proposed C-RAN architectures which co-locate BBUs to allow sharing of resources. C-RAN architectures place additional demands on front-haul latency which, in some cases, can be better served by microwave links. For these emerging front-haul microwave links the same partner scalable modem IP can be used to provide front-haul solutions.
