Course Description

The Global System for Mobile communications (GSM) is the world’s dominant wireless technology. It’s no exaggeration to state that every wireless technology that has some since GSM has been impacted by it, at least in a conceptual way. This course will give participants a thorough understanding of the architecture, protocols and operation of the GSM networks. Tthis course explains the concepts and implementation of the network in detail. The program explores the technology in a logical format, including the Radio Access network, Core network, and the required underlying systems. The protocols are examined in depth and signalling flows are used where necessary to illustrate the operation.

The course also provides a technical overview of UMTS, HSPA and HSPA+ technology and its evolution UMTS Training covers 3G system overview, High Speed Packet Access HSPA. You will Learn about UMTS services, UMTS Planning, Architecture, Design and Deployment, UMTS Air Interface, IP Multimedia Subsystem (IMS), UMTS Security, UMTS Billing and Management.
