Analyzing HSPA+

With the ever increasing demand for bandwidth, service providers have upgraded their third generation network based on UMTS to support mobile broadband. Termed HSPA (High Speed Packet Access), this course focuses on the modifications that have been made to the packet channels operating across the radio interface in terms of throughput enhancement methods, HSPA+ sessions and HSPA+ operational procedures.
