A detailed technical description of the technologies available to be used to support the backhaul requirements of evolved 3G HSPA and next generation 4G LTE access networks. This includes discussions of underlying backhaul architecture and concepts along with more detailed discussions of the technologies employed to support evolved radio access networks, including: Carrier Ethernet, MPLS, fibre-optic transmission and packet-based microwave plus other high capacity backhaul technologies.
Who would benefit
This course is suitable for engineering and technical management staff who are involved in the commissioning, design, deployment or operation of mobile backhaul networks.
An understanding of mobile network architecture and operation would be beneficial as would an appreciation of legacy backhaul technologies such as TDM or ATM.
