Introduction This paper provides an overview of Long Term Evolution (LTE) and Worldwide Interoperability for Microwave Access (WiMAX)—the leading technologies for next-generation mobile broadband. The information presented here will help readers understand how the two technologies differ, why Verizon Wireless chose LTE, and what advantages LTE offers customers. The following executive summary gives a quick overview of the paper’s contents and its subject matter. The remaining sections go into greater technical detail about LTE and WiMAX wireless technologies. 1.1 Audience This paper has been developed for independent customers, enterprise customers, IT administrators, decision makers, and other personnel. It is assumed that the reader has an understanding of earlier generations of wireless technology, as well as an understanding of computer and network concepts. 2. Executive Summary Driving the evolution of wireless broadband technology is customers’ increasing expectations for speed, bandwidth, and global access. Customers want more information, such as business and consumer applications, and entertainment available through their mobile devices, but with greater speeds. For wireless carriers to achieve greater speeds and pervasive connectedness, their networks need to start behaving more like landline IP-based networks. This line of thinking represents a fundamental shift in perspective—from mobile services to broadband connections—for customers and service providers alike. Enter the fourth-generation (4G) wireless network. Unlike earlier wireless standards, 4G technology is based on TCP/IP, the core protocol of the Internet. TCP/IP enables wireless networks to deliver higher-level services, such as video and multimedia, while supporting the devices and applications of the future. Verizon Wireless chose LTE over WiMAX as the technological foundation for its 4G wireless broadband network. The company believes that LTE offers a number of significant technological and business advantages over WiMAX that make it a superior networking standard. Verizon Wireless customers want to be truly untethered with advanced communication devices that provide a similar immersive experience as found in today’s wired networks—whether it’s downloading or uploading large files, video, gaming, downloading music, or social networking. They want to be able to communicate in new and innovative ways whenever and wherever they choose around the globe. For these reasons, Verizon Wireless believes LTE is the best technology with the global scale needed to deliver such experiences. 3. The Benefits of LTE • Provides a global ecosystem with inherent mobility • Offers easier access and use with greater security and privacy • Dramatically improves speed and latency • Delivers enhanced real-time video and multimedia for a better overall experience • Enables high-performance mobile computing • Supports real-time applications due to its low latency • Creates a platform

  • Migration to 3G Wireless Broadband Internet and Real Options: the Case of an Operator in India
    ARTICLE IN PRESS Telecommunications Policy 30 (2006) 400–419 www.elsevierbusinessandmanagement.com/locate/telpol Migration to 3G wireless broadband internet and real options: The case of an operator in India Venkata Praveen TanguturiÃ, Fotios C. Harmantzis Telecommunications Management, School of Technology Management, Stevens Institute of Technology, Hoboken, NJ 07030, USA Abstract The paper focuses on third generation wireless technologies and on alternative technologies for wireless local area networks. The authors present the evolutionary migration path from second to third generation systems. Technological, economic and behavioral factors related to decision-making towards the migration are proposed. As an example, the paper studies the case of the national incumbent operator of India. It analyzes qualitatively the migration problem from the perspective of the operator, the equipment manufacturer and the users. For the quantitative analysis, real options are used to value the investment decisions. The analysis suggests that the initial (sunk) investment cost, the average revenue per user, the growth of the subscriber base and the volatility of the markets are the key factors in the investment process. r 2006 Elsevier Ltd.

  • Analysis of Wifi and Wimax and Wireless Network Coexistence
    International Journal of Computer Networks & Communications (IJCNC) Vol.6, No.6, November 2014 ANALYSIS OF WIFI AND WIMAX AND WIRELESS NETWORK COEXISTENCE Shuang Song and Biju Issac School of Computing, Teesside University, Middlesbrough, UK ABSTRACT Wireless networks are very popular nowadays. Wireless Local Area Network (WLAN) that uses the IEEE 802.11 standard and WiMAX (Worldwide Interoperability for Microwave Access) that uses the IEEE 802.16 standard are networks that we want to explore. WiMAX has been developed over 10 years, but it is still unknown to most people. However compared to WLAN, it has many advantages in transmission speed and coverage area. This paper will introduce these two technologies and make comparisons between WiMAX and WiFi. In addition, wireless network coexistence of WLAN and WiMAX will be explored through simulation. Lastly we want to discuss the future of WiMAX in relation to WiFi. KEY WORDS WiMAX, WiFi, wireless network, wireless coexistence, network simulation 1. INTRODUCTION With the development of multimedia communication, people need wireless broadband access with higher speed, larger coverage and mobility. The emergence of WiMAX (Worldwide Interoperability for Microwave Access) technology met the people's demand for wireless Internet to some extent. If wireless LAN technology (WLAN) solves the access problem of the "last one hundred meters", then WiMAX technology is the best access solution of the "last mile". Though WiMAX is an emerging and extremely competitive wireless broadband access technology, the development prospects of its market is still unknown. Hybrid networks as a supplement to cell based or IP packet based services, can fully reflect the characteristics of wide network coverage.

  • The Truth About Wireless Broadband: the Myths and Challenges of Wireless Technology in Rural America
    The TruTh abouT Wireless broadband: The MyThs and Challenges of Wireless TeChnology in rural AmeriCa Rural Telecom Educational Series The TruTh abouT Wireless broadband: The MyThs and Challenges of Wireless TeChnology in rural AmeriCa execuTive summary Today’s wireless networks would not work without a fiber or other wired network supporting them. although wireless signals can be transmitted through the air for a few miles, they are subject to interference from buildings, hills and mountains, trees, and other obstacles that interfere with the line of sight between antenna towers and other facilities. in addition, wireless services share the air, or spectrum, with each other, and an overflow of simultaneous users can crowd out or slow down other users and cause service degradation. for these reasons, as explained more fully in this paper, new 4g wireless networks will be designed to carry a wireless signal for only a relatively short distance before transferring it (whether it be a voice call, text message, or e-mail) to the wireline network buried underground or strung across utility poles. if the call or text message is directed to another wireless user, only when the signal reaches a wireless facility near the end-user’s device does the signal leave the wired network to complete its journey wirelessly. in urban areas, a relatively few number of antennas can reach many people; for example, an array of cell phone antennas atop a downtown office building can reach not only the people in the building but also numerous others nearby. in rural america, however, people live and work much farther apart from one another.

  • Long Term Evolution (LTE) & Ultra-Mobile Broadband (UMB)
    Long Term Evolution (LTE) & Ultra-Mobile Broadband (UMB) Technologies for Broadband Wireless Access Subharthi Paul [email protected] (A survey paper written under guidance of Prof. Raj Jain) Download Abstract The evolution of wireless telephone technologies can be discretely grouped into various generations based on the level of maturity of the underlying technology. The classification into generations is not standardized on any given metrics or parameters and as such does not represent a strict demarcation. However, it represents a perspective which is commonly agreed upon, both by industry and academia, and hence conceived to be an unwritten standard. At this time, there are two major efforts towards the development of the next generation - "4G" wireless access technology. The 3GPP or 3rd Generation Partnership project (brand named as Long Term Evolution) is the name of the 4G efforts being undertaken in Europe and the 3GPP2 or 3rd Generation Partnership project 2 (brand named as Ultra Mobile Broadband) is the 4G effort of North America and parts of Asia. This survey tries to present an evolutionary and objective sketch to the development efforts of these technologies that mark the future of wide area broadband wireless access technologies.
