As smartphones become more complex and features such as Voice-over-LTE (VoLTE), MIMO and Carrier Aggregation (CA) begin to evolve into multi-band devices, the delivery of a quality user experience remains extremely important on the service providers list of priorities. The performance demands of the industry must be met. Network operators seek to ensure that LTE devices meet user functionality and experience expectations not only during testing and certification, but throughout the remaining lifecycle of mass produced devices.

Workshop Goals

  • Explore how the industry can ensure radio performance quality throughout the end-to-end lifecycle of mobile devices
  • Understand radio performance impacts of functionality and ways to test such impacts as devices proliferate with Carrier Aggregation, VoLTE, and other evolutionary technologies
  • How to protect the customer experience by defining appropriate radio requirements and certification/production processes translating to a preferred Quality-of-Experience
  • Identifying/resolving issues in the live network
