High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA) optimize UMTS for packet data services in the downlink and uplink, respectively. Together, they are referred to as High Speed Packet Access (HSPA). Within 3GPP Release 7, 8, 9 and 10, further improvements to HSPA have been specified in the context of HSPA+ or HSPA evolution. This Application Note describes how HSPA+ features can be tested using Rohde & Schwarz instruments.
