A new radio interface called W-CDMA (Wideband Code Division Multiple Access) was specified in Release 99. From there onwards, multiple releases have been standardized to continue the evolution of UMTS. HSPA (High Speed Packet Access) was the next step in the evolution and it was standardized in Releases 5-6. After HSPA, 3GPP has also defined Evolved HSPA (HSPA+) in Release 7. The longer term evolution of UMTS/HSPA networks has been named as EPS
