Course 572: UMTS Fundamentals

This course provides an advanced technical overview of current and coming UMTS technologies

After successfully completing the course the attendees will:

• Understand the evolution from GSM to UMTS
• Understand the basics of UMTS radio communication
• Examine UMTS Radio Access Network (UTRAN)
• 3GPP release 99, 4, 5 and 6
• Understand the UMTS Core Network
• Examine the services in the UMTS core network environment
• Understand UMTS Protocols
• Understand Services in the UMTS Environment
