Analysis of the urban/rural broadband divide in Canada: Using GIS in planning terrestrial wireless deployment 总被引：3，自引：0，他引：3

Millions of Canadians residing in Canada's northern, isolated, rural, and remote communities do not have broadband Internet access. This situation has led to a national “broadband divide.” That is, the deployment of wireline broadband is very limited in Canada's northern, isolated, rural, and remote areas because of the significant expense of installation and maintenance of the wired infrastructure needed to reach dwellings in these locations.Terrestrial broadband wireless technology, on the other hand, does not entail the same kind of physical infrastructure. As a result, there are dramatic changes in how spatial considerations affect the provision of broadband Internet services (BIS) to areas beyond the urban zone. In particular, the spatial question is now focused on assessing the capacity for different technological solutions to reach profitable population bases, and brings to the forefront organizations that are developing non-line-of-sight (NLOS) technologies that would permit wireless Internet access over much greater distances than current solutions.We begin this paper by establishing the importance of broadband connectivity to Canada's northern, isolated, rural, and remote communities. This discussion comments on the role of the Government of Canada in the provision of broadband connectivity to residents of these communities, and outlines the current regulatory issues that govern wireless services and policy formulation.The second part of the paper illustrates the use of geographic information system (GIS) approaches in the study of wireless broadband planning and deployment. Case study findings suggest that GIS applications can make a significant contribution to the analysis of wireless deployment planning, to the understanding of the relationships between wireless signal sources and consumers, and to the spatial configuration of terrestrial wireless broadband networks. We conclude the paper by discussing how the GIS approach employed could be used to inform the public policy process with regard to increasing access to broadband Internet services in all regions of the country, and thereby providing the opportunity for all Canadians, regardless of location, to fully participate in the Information Society. 相似文献

With the rapid development of Chinese e-government, Chinese citizens are encouraged to access e-government services as their convenience. However, the accessibility of Chinese e-government Web sites has been overlooked. This research study tries to provide an overview of the accessibility of Chinese local government Web sites. Three hundred twenty-four Chinese local government Web sites were examined to find out how accessible they are with reference to the Web Content Accessibility Guidelines 1.0 (WCAG) published by the World Wide Web Consortium (W3C). This research found that all the surveyed Chinese e-government Web sites failed one or more W3C's accessibility measures and thus many disabled Chinese people may have substantial problems to access them. Several valuable recommendations are made based on the research findings and the China's actual conditions. 相似文献

U.S. federal websites are required to be accessible for people with impairments. However, despite the existing regulations and guidelines, many federal websites continue to be inaccessible, and accessibility policy statements available on federal websites often do not provide any useful information. This paper provides three contributions to the research literature: (1) an accessibility evaluation of 100 federal home pages using both human and automated methods, (2) a content analysis of existing website accessibility policy statements, and (3) a discussion of the relationship between actual Section 508 compliance and the existing accessibility policy statements on a website. The paper concludes with recommendations for improving policy related to Section 508 compliance for websites. 相似文献

This article examines whether Section 255 of the 1996 Telecommunications Act achieves accessibility for people with disabilities. Taking the interest group approach, it shows that the Federal Communications Commission (FCC) implemented Section 255 in a way that is favorable to the telecommunications industry and not to people with disabilities. The FCC's regulations only encourage the telecommunication industry to consider accessibility issues for people with disabilities. This proindustry regulatory bias is in keeping with the established pattern of policymaking in other areas concerning people with disabilities. The paper argues that if the FCC continues to rely on the voluntary efforts of the industry, people with disabilities will not enjoy benefits of access to telecommunications systems. 相似文献

Distributed education delivered via the Internet is a growing practice, with most institutions offering at least course websites
and many expanding to full course offerings and even online degree progams. There are two schools of thought with regard to
delivery mode: the larger group has focused on asynchronous delivery, accessible at any time via webpages and interactive
tutorials and quizzes, while a smaller group advocates synchronous delivery where students are online and interact during
class time. This paper summarizes the advantages and disadvantages of the two delivery modes and describes our successful
and growing experience of more than a decade using an open source synchronous delivery tool blended with a variety of asynchronous
capabilities and classroom instruction. We conclude that a synergistic combination of the two modes with in-person instruction,
designed to provide maximum flexibility to the student within the constraints of the subject, offers the best support for
student learning.
