  • 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.

  • Broadband and Digital Divide Glossary
    Broadband and Digital Divide Glossary 5G The fifth generation of mobile connectivity. This technology enables speeds that are projected to be at least 10 times faster than current 4G speeds with lower latency, lower battery power consumption, and capacity to handle many more connections from a single radio. BIT The smallest unit of information data is measured as a bit or binary digit. BIT RATE The speed of internet is measured by how fast data is transferred over a period of time. This is also known as the bit rate or the number of bits that are processed over a period of time, usually one second. BROADBAND The Federal Communications Commission (FCC) defines broadband as internet service with a download speed of at least 25 megabits per second (Mbps) and an upload speed of 3 megabits per second (Mbps). Broadband provides internet access via a variety of wired and wireless networks. BROADBAND NETWORK The broadband network is made up of first, middle, and last mile: • The first mile consists of a very high-capacity fiber optic backbone that transmits large amounts of data over long distances; • The middle mile links the backbone to the internet service providers (last mile) access network; • The last mile brings the connection to a home or business. The last mile can be provided using different transmission media such as Digital Subscriber Line (DSL), Cable, Fiber, Wireless, and Satellite. CABLE Provides broadband connection over the same coaxial cables that deliver cable television service. This is the most prominent broadband technology in densely populated areas. CALIFORNIA PUBLIC UTILITIES COMMISSION (CPUC) The CPUC regulates privately owned public utilities in the state of California including electric power, telecommunications, natural gas, and water companies.
