HSPA to LTE Advanced

UMTS-HSPA, in particular, has many key technical and business advantages over other mobile wireless technologies. Operators worldwide are now deploying bot High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA), the combination of the two technologies called simply HSPA. HSPA is the most capable cellulardata technology ever developed and deployed. HSPA, already widely available, follows the successful deployment of UMTS networks around the world and is now a standard feature.

HSPA is strongly positioned to be the dominant mobile-data technology for the next five to ten years. To leverage operator investments in HSPA, the 3GPP (Third Generation Partnership Project) standards body has developed a series of enhancements to create “HSPA Evolution,” also referred to as “HSPA+.” HSPA Evolution represents a logical development of the Wideband Code Division Multiple Access (WCDMA) approach, and it is the stepping stone to an entirely new Third Generation Partnership Project (3GPP) radio platform called 3GPP Long Term Evolution (LTE). LTE, which uses Orthogonal Frequency Division Multiple Access (OFDMA), will be ready for deployment in 2010. Simultaneously, 3GPP — recognizing the significant worldwide investments in GSM networks—has defined enhancements that will significantly increase EDGE data capabilities through an effort called Evolved EDGE.

Combined with these improvements in radio-access technology, 3GPP has also spearheaded the development of major core-network architecture enhancements such as the IP Multimedia Subsystem (IMS) and the Evolved Packet Core (EPC), previously called System Architecture Evolution or SAE, as well as developments in Fixed Mobile Convergence (FMC).These developments will facilitate new types of services, the integration of legacy and new networks, the convergence between fixed and wireless systems, and the transition from circuit-switched approaches for voice traffic to a fully packet-switched model.

The result is a balanced portfolio of complementary technologies that covers both radioaccess and core networks, provides operators maximum flexibility in how they enhance their networks over time, and supports both voice and data services.

This paper discusses the evolution of EDGE, HSPA enhancements, 3GPP LTE, the capabilities of these technologies, and their position relative to other primary competing technologies.
