A Primer on Fronthaul and Backhaul
This report provides a brief overview of two elements of the mobile operator’s network:
• Backhaul: The connection between the baseband units and the EPC. • Fronthaul: The connection between remote radio heads/units (RRHs/RRUs) and baseband units.
From these basic definitions emerge great complexity, particularly when the variations on each type are described. This report is offered as a primer to those more detailed topics that iGR has covered or will cover in existing or future reports.
