In recent years, the landscape for wireless technology has changed substantially, with profound implications for the evolution of last-mile access infrastructure. This paper provides a high-level introduction to emerging trends in wireless technology, with a special focus on how these are impacting municipal broadband deployments. Also discussed are some of the key architectural and design choices for wireless networking systems and their implications for cost and system performance. In addition, examples are provided regarding how the new wireless technologies are being deployed by municipalities in a variety of contexts, with reference to wireless technologies currently available from vendors. The policy implications of these trends are discussed further in a companion paper in this issue. 相似文献

The current universal service policies for the Internet focus almost entirely on physical connectivity. This emphasis is misplaced because the Internet is an overlay network that rides piggyback on the existing telecommunications infrastructure. The focus instead should be on Internet services and the end-user equipment and training needed to access them. 相似文献

This paper describes a research project that was designed to provide a group of bright undergraduate students with a meaningful research experience that would encourage and motivate them to attend graduate school for further education and research. The project illustrated basic research techniques and the nature of the job of a researcher to undergraduates who had had limited or no opportunities for research. The students were involved in all phases of the project to ensure that they would gain the confidence needed to do research on their own. In this project the students were given an opportunity to do research that involved parallel processing. 相似文献

AbstractLittle research has been published as to the ways in which the commercial aspects of the Fédération Internationale de Football Association’s (FIFA) World Cups are organized. Extant literature has instead tended to focus upon infrastructure issues, economic geography, and cultural aspects. Drawing upon ‘swarm theory’ and historian Wray Vamplew’s typologies of entrepreneurial activity in sport, we compare and contrast the commercial aspects of two World Cups; first, the 1966 tournament held in England, the first time that a serious attempt had been made to produce and licence a mascot character (‘World Cup Willie’) to exploit merchandizing opportunities. This approach became an important part of World Cups thereafter; Second, the 1994 tournament in the USA, the most commercially successful World Cup ever, realizing record profits and catalyzing the re-launch of elite professional soccer in the USA. These cases enrich understanding of the networks and entrepreneurial activity of the World Cup, one of the most significant sporting and cultural mega-event projects in the world. 相似文献

Wireless is changing the policy calculus for municipal broadband 总被引：1，自引：0，他引：1
Historically, the justification for municipal provisioning of “last-mile” communications infrastructure has focused on the natural monopoly aspect of wireline infrastructure. Growing interest in wireless ISPs, municipal hot spots, and access to public space for siting wireless infrastructure suggests new and expanded opportunities for local government participation in telecommunication services. This paper examines the implications of emerging wireless technologies for the policy debate over whether municipalities should be playing an active role in providing last-mile broadband services and, if so, what the nature of that role should be. 相似文献

ABSTRACTThe 1966 FIFA World Cup has become part of the iconography of its hosts and champions, England. Extant literature has tended to focus on the cultural and symbolic legacy of the tournament, or engaged with diplomatic relations between Britain and North Korea. Contrastingly, we use archival sources from footballing and government institutions to explore the less studied topic of how the tournament was reported and perceived in Latin America, where England had commercial interests and influence, but where there were allegations that FIFA, the FA and even the UK government manipulated the tournament to the advantage of England and other European teams. We provide fresh perspectives on the social and cultural significance of the 1966 FIFA World Cup by analysing how the tournament’s organizers attempted to manage the situation and resulting negative public relations, and how 1966 fits within longer-term footballing and diplomatic relations between England and Latin America. 相似文献
