Technology & Learning - October 2007 - (Page 16) The question of adequate bandwidth is increasingly the issue of the day. By Karen Greenwood Henke ust how much bandwidth does the average student in the United States have access to today, and how much will he or she need in the future? That depends…is the answer from district CTOs, state technology directors, industry experts, and classroom teachers. The National Center for Education Statistics reports that 97 percent of U.S. public schools with access to the Internet used broadband connections in 2005 (http://nces.ed.gov/fastfacts/ display.asp?id=46). But broadband encompasses a broad range of bandwidth. As capacity gets divided among more students using increasingly demanding data, voice, and multimedia applications, every student’s service degrades. JASON Project or to create a report on earthquakes using U.S. Geological Survey maps depends on the speed, availability, and reliability of each part of the pipeline, including: 1. The speed and quality of the device used for access. A computer, laptop, or handheld device requires memory, graphics ability, and a 100 megabit per second (Mbps) or better connection for most of today’s Web browsing. 2. The capacity of the internal school network, or local area network, which includes all instructional J computers, administrative connections, and may include servers. 3. The capacity of the line from the school to the district, the wide area network, where many students and teachers may be connecting to testing servers, student information systems, content management systems, and other large network applications. 4. The capacity of the connection from the district office to the Internet or another service provider. Internet service contracts should guarantee a bandwidth level such as 1.5 Mbps T-1 services and should not split T-1 lines between multiple customers. At each of these junctures, the more users who tap into the pipeline and the more demanding their applications, the less capacity available to everyone.
