3G UMTS Network Planning and Optimization Training


The Universal Mobile Telecommunications System – UMTS- is the Third Generation mobile system deployed across Europe and beyond. It builds on the success of GSM and GPRS with new radio spectrum to provide higher data rates. 3G systems and services are making a significant impact on the mobile communications industry by providing an enhanced user experience.

This highly interactive 3G & 3.5G Explained training course offers an excellent grounding for those who need to understand the scope, implementation options, business drivers and rollout strategies for 3G.

This course covers 3G technologies such as W-CDMA, HSDPA, HSUPA, cmda2000, IP and IMS, as well as services and applications.

Course Objectives

  • Understand the requirements for 3G networks, chart migration strategies (incl. radio and core networks requirements and the evolution to all IP networks) and discuss how these are being met in practice and their likely success
  • Gain an understanding of IMS including its benefits, features and potential services
  • Draw a simplified schematic diagram showing the network and service architecture of the evolving 3G system
  • Learn the principals and capabilities of CDMA technology and how these are applied to the radio interface used UMTS and cmda2000 networks
  • Be able to compare its suitability against alternative access schemes (i.e. WiFi and WiMAX) for specific applications
  • Discuss the issues relating to planning 3G radio networks
