ENG-510 4G Mobile Networks





*This course is also available as a live distance learning course*

Driven by the user demand for increasingly complex applications built on data intensive platforms. 4G LTE was developed to augment the data handling capabilities of 3G UMTS. 3GPP (3rd Generation Project Partnership - the mobile industry's standards body) identified the requirements and built the standards which constitute the foundation for today's 4G LTE networks.

This 2-day course concentrates on the cellular deployment of the 4G LTE platform at a conceptual high level, delving into topics such as the LTE system sub-architecture of radio access and core network, the handling and mobility aspects of todays' services provided over LTE, including end-to-end QoS and security. It also discusses the aspect of spectral efficiency achieved through the application of the developed standards.

Learning Outcomes

Upon completion of the course, participants will be able to:
  • Explain what LTE (Long Term Evolution) and EPC (Evolved Packet Core) really are
  • Describe LTE standardization and the role of 3GPP
  • Discuss LTE services and business environment
  • Compare and contrast evolving service functionalities enabled by 4G LTE List LTE and EPC terminology, services and features
  • Describe how mobility and hand-over enhancements work over earlier platforms
  • Explain how spectral efficiency is achieved in the 4G LTE environment
  • Appreciate the struggle to allow low bandwidth applications, such as voice to utilize the 4G LTE platform
