OVERVIEW
With the rapid uptake in mobile broadband subscribers and the increase in use of smart phones and high speed modems on our mobile networks, customer are now generating vast amounts of data traffic which is putting the existing transport infrastructure under great strain. It is clear that traditional E1 links cannot support this demand efficiently so new packet-based transmission systems are being implemented to meet traffic requirements more cost effectively. However, the market presents a huge range of backhaul options and selecting the best fit for your network is a complex job. This course identifies the leading packet based transmission options that are available and compares their suitability in a number of deployment scenarios. Hybrid solutions that deal with the transmission of circuit and packet switched services are also discussed. At the end of this program, participants will understand the issues related to the various solutions in terms of complexity, cost, resilience, QoS and synchronisation.
You will be able to
- Identify issues related to traditional backhaul technologies
- Outline different options available for high speed backhaul over Copper, Microwave & Fibre
- Describe the basic operation of MPLS, Metro Ethernet & Next Generation SDH
- Define how to meet quality requirements via IP backhaul
- Perform simple planning & dimensioning of a transport network
Who Can Benefit
Technical staff who need to be able to compare key next generation backhaul solutions for different deployment scenarios
Pre-requisite Knowledge
The participant should have a good understanding of cellular 3G/UMTS networks & CIPA level IP or equivalent.
