Mobile Fronthaul Vs Mobile Backhaul | Difference between Mobile Fronthaul and Mobile Backhaul
This page compares Mobile Fronthaul Vs Mobile Backhaul and mentions difference between Mobile Fronthaul and Mobile Backhaul.
Introduction: As we know next generation of wireless system uses two parts viz. central Unit (CU) and Distributed Units (DUs). CU can control DUs using C-RAN (Centralized Radio Access Network).
A CU controls multiple DUs simultaneously. Moreover CU processes data to/from DUs and handles co-ordination control functions between DUs. A DU consists of antennas, RF and baseband processing equipments etc.
Mobile Fronthaul:
The mobile front end interfacing part of the cellular network is known as mobile fronthaul.
It consists of Base Station or NB towers equipped with RRHs (Remote Radio Head)
referred as small cells.
Mobile Backhaul:
The back end part of cellular network which connects fronthaul with voice/data
circuits is known as Mobile backhaul. It houses COs (Central Offices) and BBUs (Baseband Units)
as well as IP MPLS network along with IP routers.
• The mobile fronthaul and mobile backhaul are connected using optical fiber which
transfer information at the rate of 10 Gbps.
• With advancement in multi-antenna array technologies, DU housing 128 antenna elements (64 transmitters and 64 receivers) can communicate with
CU of backhaul at the speed of about 320 Gpbs as defined in CPRI standard.
