HSPA and HSPA+ training course description

HSDPA (High Speed Downlink Packet Access) and HSUPA (High Speed Uplink Packet Access) provide speeds of upto 14Mbps downlink and 5Mbps uplink. This theory-based course provides an overview of the 3GPP R5 and R6 HSDPA/HSUPA standards and the technologies which are involved. The HSPA+ R7 enhancements are also covered.

What will you learn

• Explain the relationship between HSPA and UMTS.
• Describe the benefits of HSPA/HSPA+
• Explain the HSPA/HSPA+ technical enhancements.
• Explain packet flows in HSPA/HSPA+.
• Recognise the migration issues involved with HSPA/HSPA+
