    The Next Generation of Wireless: 5G 5G Leadership in the U.S. Thomas K. Sawanobori SVP and Chief Technology Officer, CTIA February 9, 2016 5G Source: Volvo Cars Entire industries, from agriculture to transportation, will be transformed to be more capable, efficient, and intelligent. That’s the promise of the next-generation of wireless technology, known as 5G. Wireless connectivity touches every aspect of our daily lives today, but we are just scratching the surface of its consumer benefits. Imagine a future where nearly everything is connected to ubiquitous, very high-speed wireless networks. Imagine enjoying enriched entertainment while riding to work in a self-driving car, doctors that monitor patients’ vital signs remotely in real-time, and communities that are smarter and more connected. Entire industries, from agriculture to the wireless ecosystem evolves from transportation, will be transformed 4G LTE to 5G. U.S. carriers including Responsiveness to be more capable, efficient, and AT&T, T-Mobile, Verizon, Sprint, US intelligent. That’s the promise of Cellular, and suppliers, including the next-generation of wireless Ericsson, Nokia, Intel, QUALCOMM, Three Key technology, known as 5G. Samsung, Cisco, Microsoft, Motorola, Consumer CommScope, HP, and others are Benefits Speed United States leadership in this next- of 5G generation of wireless is critical. We partnering to drive foundational 5G are a global leader in 4G LTE. 99.6% activities on technology and global standards-setting fronts. One U.S. of Americans now have access to a 4G Connect 1 operator has announced trials of 5G LTE network, thanks to nearly $150 Everything billion invested since 20102 by wireless networks; others are working hard on operators large and small.

  • Lte-Advanced Release-12 Shapes New Enodeb Transmitter Architecture: Part 1, Technology Evolution
    Keywords: RF DAC, RF digital-to-analog converter, LTE-Advanced, direct RF conversion, carrier aggregation, MIMO, active antenna system, eNodeB, radio access technology APPLICATION NOTE 6062 LTE-ADVANCED RELEASE-12 SHAPES NEW ENODEB TRANSMITTER ARCHITECTURE: PART 1, TECHNOLOGY EVOLUTION By: Damian Anzaldo, Principal Member of Technical Staff—Field Applications, Maxim Integrated Abstract: Analog integration plays an important role in addressing new challenges faced by LTE-Advanced radio engineers. The 3rd Generation Partnership Project (3GPP) is working on Release 12 (Rel-12) of the LTE-Advanced standard. 3GPP Rel-12 includes many enhancements to 4G radio access technology including wideband carrier aggregation, multi-layer spatial multiplexing and advanced antenna configurations. The Rel-12 enhancements will challenge radio designers to integrate more RF transmitter channels that will enable smaller, lower power and higher performance eNodeB base stations. Advancements in RF analog integration and disruptive radio architectures can help engineers successfully overcome the integration challenge. Introduction This two-part application note series reviews new developments in the Fourth Generation Long Term Evolution (4G-LTE) cellular standard. The application note series explores LTE-Advanced (LTE-A) Release-12 (Rel-12) features and the impact on eNodeB radio frequency (RF) transmitters. The application notes reveal how analog integration can overcome design challenges arising from the latest 4G developments. A Glossary of Technical Terms is appended to the end of each application note. Part 1, this application note, examines market forces driving global adoption of the LTE standard and trends in 4G radio access technology. Readers will learn about work items outlined in the 3rd Generation Partnership Project (3GPP) Rel-12 specification.

  • UMTS to Mobilize the Data World
    UMTS to Mobilize the Data World A report on the progress of UMTS By: Chris Pearson Executive Vice President Vicki Livingston Director of Marketing www.3gamericas.org February 2003 UMTS to Mobilize the Data World Preface 3G Americas provides this report on the tremendous progress of Third Generation UMTS technology in preparation for the dozens of commercial launches to occur in 2003. Our organization is committed to the GSM evolution of GSM/GPRS/EDGE and UMTS (WCDMA) and its seamless deployment throughout the Americas. The first vision of what UMTS might become emerged in a workshop report in 1995. Standardization work did not begin until after the UMTS Task Force’s published results in mid- 1996 and ETSI’s subsequent UTRA decision in January 1998. Thus, based on the historical patterns demonstrated by introductions of other new wireless technologies, it could be expected that UMTS would first be realized somewhere between 2002 and 2004. As the business case emerges for wireless data services, we are also seeing the completion of UMTS trials, deployments of UMTS infrastructure, commercial announcements of dual-mode GSM/UMTS handsets, and a general readiness of the marketplace for the mobilization of data throughout the world with UMTS. Additionally, 2003 will see the deployment of EDGE throughout the Americas and other regions of the world. EDGE and UMTS are complementary technologies, able to interoperate and be deployed in tandem within an operator’s network. The flexibility of the GSM family of technologies allows for optimal capacity, cost efficiency, and global interoperability as the leading standard chosen by over 785 million subscribers.
