Engineering the Mobile Network (3 days or 18 hours)
Over the past twenty years, the growth in cellular technologies has simply been phenomenal! This course sets out to provide attendees with a comprehensive foundation in the key 2G and 3G technologies; GSM, GPRS and UMTS. Incorporating not only the components of the network, but also detailed explanations and analysis of the various procedures; Attach, Call Setup, PDP Context Activation, Mobility etc, the course ensures attendees leave with a complete understanding of how a 2G / 3G network operates. The course also includes the mpirical Interactive which features real network traces and student exercises.
