Mobile broadband now represents the leading edge in innovation and development for computing, networking, Internet technology, and software. Major developments this past year include not only 3rd Generation (3G) ubiquity, but rapid initial deployment of 4th Generation (4G) networks, deepening smartphone capability; the availability of hundreds of thousands of mobile applications; the maturing of new form factors such as tablets; a better understanding of what the industry needs to do to address exponentially growing data demands; and acknowledgment by industry and government of the need for more spectrum. Most of the wireless industry has even redefined the meaning and marketing of the term “4G,” allowing 2011 to be the year of widespread 4G deployment through technologies such as High Speed Packet Access Evolved (HSPA+), Long Term Evolution (LTE), and Worldwide Interoperability for Microwave Access (WiMAX). Through constant innovation, Universal Mobile Telecommunications System (UMTS) with HSPA technology has established itself as the global, mobile-broadband solution. Building on the phenomenal success of Global System for Mobile Communications (GSM), the GSM-HSPA ecosystem has become the most successful communications technology family ever. Through a process of constant improvement, the GSM/Third Generation Partnership Project (3GPP) 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. HSPA remains strongly positioned to be the dominant mobile-data technology for the next five to ten years. To leverage operator investments in HSPA, the 3GPP standards body has developed a series of enhancements to create “HSPA Evolution,” also referred to as “HSPA+.” HSPA+ represents a logical development of the Wideband Code Division Multiple Access (WCDMA) approach, and it is the stepping stone to an entirely new 3GPP radio platform called 3GPP LTE. LTE, which uses Orthogonal Frequency Division Multiple Access (OFDMA), is seeing widening deployment this year. Simultaneously, 3GPP—recognizing the significant worldwide investments in GSM networks—has significantly increased Enhanced Data Rates for GSM Evolution (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

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.

  • 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.

  • Testimony Before the Political Subdivision Taxation Committee In
    APPENDIX I Testimony before the Political Subdivision Taxation Committee in support of the Telecommunication Infrastructure Sales Tax Exemption - June 29, 2016 - Chairman Dockter, Political Subdivision Taxation Committee members, for the record my name is Todd D. Kranda and I am an attorney with the Kelsch Kelsch Ruff & Kranda Law Firm in Mandan. I appear before you today as a lobbyist on behalf of Verizon Wireless to express· support for the existing telecommunication infrastructure sales tax exemption found in Chapter 57-39.2 of the North Dakota Century Code at Section 57-39.2-04.9. As background information for this telecommunication equipment infrastructure sales tax exemption, the 2007 Legislature passed HB 1018, which included in Section 28, a study of wireless providers and how wireless service impacts the business climate in ND. The interim study was assigned to the Industry Business & Labor Committee. As a result of that study the interim Industry Business & Labor Committee approved SB 2040 for the 2009 Session. SB 2040 was intended to promote the expansion of businesses in ND by the additional investments that are made with the construction and expansion of telecommunication infrastructure. SB 2040 provided a sales and use tax exemption for equipment used in telecommunications infrastructure development. SB 2040 passed and became Section 57-39.2-04.7 NDCC. Subsequently, in 2011 SB 2171 was presented to extend the sunset that was included with the 2009 legislation. SB 2171 passed to extend the sunset provision through December 31, 2012. In 2013, SB 2142 was passed to reestablish the sales and use tax exemption for equipment used in telecommunications infrastructure development that was lost with the December 31, 2012 sunset provision.
