The presentation will examine the role of synchronization in mobile networks, compare the strengths and weaknesses of the different synchronization techniques available in today's mobile networks and highlight the challenges of synchronization raised by the move to 3G networks. Mr. Ferreira will also examine how Ethernet in the backhaul isolates base stations from network synchronization as well as options for delivery of synchronization over Ethernet and recommend the best approach to synchronization in the mobile next-generation-network (NGN).

IIR's Transport Networks for Mobile Operators - Middle East focuses on the specific issues that affect operators from the Middle East and the Persian Gulf. TNMO-ME will cover issues such as how to deal with the new transport demands arising from the expansion of GPRS/EDGE/3G services wireless transmission strategies including NG-MW, BWA/WiMAX and RAN optimisation.

Mr. Ferreira joined Symmetricom in 2000 and has worked with several companies involved in synchronization over the last 18 years. His experience ranges from RF engineering to synchronization systems engineer, working closely with telecom operators and manufacturers round the world to develop solutions for virtually all applications requiring synchronization. He has written numerous papers on synchronization of wireline and wireless networks and is a steering group member of the International Telecom Synchronization Forum (ITSF) and a member of the Institution of Electrical Engineers (IEE).
