LTE has become one of the fastest wireless technologies, led by Qualcomm Technologies. It being a common standard covering both FDD and TDD flavors, allows the industry to build common FDD/TDD infrastructure, common devices, and a large common ecosystem. LTE and its evolution LTE Advanced are a crucial part of 1000x challenge.
LTE is a common global standard for both paired and unpaired spectrum. This is allowing operators to leverage all available spectrum and enabling the industry to build common FDD/TDD products as well as one large, vibrant ecosystem. Both LTE FDD and TDD offer very high data rates, low latency, and seamless interworking with 3G, as well as between FDD and TDD networks. They also leverage common core network.
Initially, the selection between LTE FDD and TDD is a matter of spectrum availability, but eventually most of the operators are expected to deploy both the modes.
LTE is overlaid on 3G networks to boost data capacity and deliver seamless, high-speed mobile data to users with LTE/3G multimode devices. 3G provides a consistent broadband experience when users move outside LTE coverage, and voice services across the network. 3G also enables global voice and data roaming for LTE devices.
Voice will gradually evolve to richer, packet-based VoLTE (voice over LTE). However, in the meanwhile, LTE devices will continue to rely on circuit-switched (CS) 3G/2G for voice (through CSFB).
Wireless networks are becoming increasingly heterogeneous with multiple modes— LTE FDD/TDD, WCDMA/HSPA+, 1X/EV-DO, TD-SCDMA and GSM/EDGE; multiple connectivity options— Wi-Fi, BT, positioning; support for over 40 bands and counting.
Adding to the complexity is the anticipated hyper-dense deployment of small cells (pico, femto, metros and more) as well as new deployment models such as neighborhood small cells, which are crucial to solve the 1000x mobile data challenge.
The device is at the center of all of this complexity. Hence its ability to solve the complexity, while providing a seamless user experience is critical for the continued success of LTE.
One of Qualcomm Technologies’ unique advantages is its ability to solve the complexities of multimode, multiband, multi-technology though its highly integrated Qualcomm® Gobi™ modems that offer leading and unparalleled feature support. This ultimately enables vendors and operators to bring their products and services to market quickly and cost-effectively.
Ever since the launch of its industry-first LTE/3G multimode, common FDD/TDD solutions, Qualcomm Technologies’ has been leading the proliferation of LTE. Our 4th generation Gobi modems, announced in Nov 2013, will take the performance to the next level. The Qualcomm RF360™ front end solution, a comprehensive, system-level solution addresses the spectrum band fragmentation challenge and enables global 4G LTE devices. Our range of Qualcomm® Snapdragon™ processor solutions integrated with Gobi modems brings multimode LTE to many smartphone tiers.
LTE Advanced is the next step in the evolution of LTE that incorporates multiple dimensions of enhancements. Carrier aggregation, the first of these features, was launched in June 2013. That will be followed by advanced antenna techniques and soon after that HetNet enhancements, which bring more out of small cells and enable hyper-dense small cell networks. These are key to address the 1000x mobile data challenge.
Supported by its vast and ever growing ecosystem, LTE technology is poised to extend its dominance into many new horizons beyond mobile broadband, be it new industries, new applications/services, or new, unexplored spectrum bands. LTE technology is versatile and robust enough to morph itself to suit the needs of these areas, while still maintaining its basic tenets of high efficiency and excellent user experience.
