Course Overview

The Backhaul in mobile networks is the portion of the network comprises the intermediate links between the Core-Network and the Radio-Access-Network (RAN).
Moving to 3G/4G mobile networks (like LTE) together with a wide range of new services that is offered,  the Backhaul networks should accommodate an increased traffic volume created by cellular coverage areas and hence, the correct dimensioning is critical from the QoS and capacity point of view.
Thus, from being an almost forgotten portion of the network the backhaul becomes, in the last few years, a major challenging issue that takes a lot of attention from the mobile network Operators/Carriers.
The course helps to find the way among the wide range of offered technologies and solutions provided by many vendors and supported by several specifications/standardization.
The Mobile Packet Backbone Network solutions are described and supported by case studies to help transport designers realize the diverse techniques. By mastering these techniques, participants will learn how to contribute to increased end-user throughput as well as increased and future-proof capacity.
This training course is also intended to provide an insight into Carrier Ethernet technologies, the Metro Ethernet Forum specifications for services and how these services can be delivered over different carrier core and access networks and transport platform along with other services deployed.
