Efficient Transport of enhanced CPRI Fronthaul over PON
03 July 2023
Passive optical networks (PONs) facilitate small cell deployments. Back- and midhaul over PON is being deployed today. As opposed to point-to-point optics, PON extends the aggregation gain into the access domain. We explain the steps taken in mobile and in PON industries to enable efficient eCPRI fronthaul over PON. We explain how fronthaul has evolved to a bandwidth efficient eCPRI, and what mechanisms are in place to enable coordinate the scheduling decisions of the mobile and the PON systems. The recent end-to-end demonstration of coordinated scheduling helps pave the way towards future industry adoption.
