UMTS for Mobile Devices (2 days or 12 hours)

The UMTS air interface provides a spectrally efficient radio carrier capable of supporting multi kilobit packet channels between the mobile and UTRAN. This course examines the protocols and procedures employed across the air interface as well as the architecture of the physical frame, transport and logical channels. In addition, complexities such as Radio Resource Control, Power Control and Interworking will also be explained. Those attending this course should have a good knowledge of cellular systems as would be gained from mpirical’s Engineering the Mobile Network course.

Who Should Attend

Mobile Device Engineers involved in the development and deployment of UMTS handsets. Product Managers requiring a detailed insight into the operation of UMTS.

Pre - Learning

Pre-Learning is provided to prime those attending the instructor led phase. Each lesson is based on an interactive online format and should take about 30 minutes to complete. The pre-Learning lessons are:
