This course is designed to give the delegate an understanding of the implementation and optimisation of WiFi and LTE interworking or WiFi offload. We investigate the requirements needed to support WiFi off load and the challenges raised.

The use of carrier class WiFi is now a necessity rather than a possibility. MNOs can save on CAPEX and reduce the need for expensive licensing mobile spectrum. The choice of own or partner with existing WiFi operators to offer seamless WiFi coverage. In either case with intelligent service provisioning MNOs profit from a range of services based on new business models.

We will investigate the technologies to support EAP-SIM enabled smartphones, traffic optimisation and traffic flows available in numerous network deployments.


Upon completion of this course the delegate will be able to;

  • Understand the need for WiFi offload
  • Describe Seamless WiFi authentication
  • Describe EAP-SIM based users
  • Explain Non-SIM users
  • Describe the three phases of seamless WiFi
  • Describe support for 801.1x in Access Points
  • Describe the requirements for EAP-SIM
  • Understand SIM Authentication
  • Understand Hotspot 2.0 & 802.11u
  • Describe the comparison between WiFi & LTE
  • Understand SIPTO
  • Describe LIPA
  • Understand the role of the ANDSF

Target Audience

Delegates who are involved in the long term evolution of cellular networks and need information on best practices and deployments we envisage, engineers, sales executives, support engineers, technical managers and anyone wishing to move into this evolving technology.
