4-days instructor-led training

Course will enable participants to:

• Understand the transmission interface requirements (Iub) in 3G networks
• Aspects of migrating from legacy transport network to 3G network using ATM and IP
• Advanced MW link planning in light of ITU-T Rec.
• Achieve better spectral efficiency with improved frequency and capacity planning techniques
• Able to derive a strategy for planning 3G BW requirements across MW

Cellular networks are rapidly migrating towards 3G and with data dominant traffic needs of backhaul requirements are changing as well. Ethernet or packet solutions across different layers of transport are a regular feature. Transmission planners are faced with several questions of what to choose for backhaul? Go for a hybrid solution or an all-IP? What are the requirements of different traffic types in 3G environment? We answer all these questions in detail with examples and cases studies in our course.

• Understanding of structures of different interfaces in 3G
• Iub, Iur understanding and its requirements
• Mapping of traffic on interfaces and its backhauling
• QoS requirements understanding
• Dimensioning of traffic between nodeB and RNC
• Features required in a packet radio
• Differentiate between hybrid and packet radio and their applications

Knowledge of Microwave link planning preferably attending the course offered by Telefocal “Microwave transmission Engineering & Link planning”

Anyone related to access transmission engineers, managers, technicians and senior managers interested in understanding the requirements of planning a 3G transmission access network.
