 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.
Through constant innovation, Universal Mobile Telecommunications System (UMTS) with High Speed Packet Access (HSPA) technology and its evolution to beyond third generation (3G) has established itself as the global, mobile-broadband solution. Building on the phenomenal success of Global System for Mobile Communications (GSM), the GSM/UMTS ecosystem is becoming the most successful communications technology family ever.
Through a process of constant improvement, the GSM family of technologies has not only matched or exceeded the capabilities of all competing approaches, but has significantly extended the life of each of its member technologies.
UMTS/HSPA, in particular, has many key technical and business advantages over other mobile wireless technologies. Operators worldwide are now deploying both High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA), the combination of the two technologies called simply HSPA. HSPA is one of the most powerful cellular-data technologies ever developed. HSPA, already widely available, follows the successful deployment of UMTS networks around the world and is now a standard feature.
Any operator deploying UMTS today is doing so with HSPA. The UMTS-to-HSPA upgrade is similar to Enhanced Data Rates for GSM Evolution (EDGE), which has already proven to be a remarkably effective upgrade to GSM networks, and HSPA (or HSDPA for some networks) is now supported by an overwhelming number of operators and vendors worldwide.
HSPA is strongly positioned to be the dominant mobile-data technology for the rest of the decade. 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), should be ready for deployment in the 2010 timeframe. 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 (or 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. ...
