DAS Boot!
Chretien, Wendy
Campus Technology, v21 n3 p20, 22 Nov 2007
The residential services group is lobbying to dump its aging hard-wired phone system because students don't use it. The town and campus public safety officials are demanding that their portable two-way radios operate well not only outdoors, but within campus buildings. Students are now expecting text messaging and WiFi service to work everywhere on campus. Faculty members are grumbling that their chosen wireless provider's coverage is good at home, but poor on campus. And the CFO wants to know why her BlackBerry doesn't work in the tunnel between the main administration building and the annex. Welcome to the wide world of wireless wants and wishes. Thankfully, it is possible to satisfy such diverse requests for unwired service. The technology required? A distributed antenna system (DAS). In essence, a DAS can connect to a variety of wireless services and then rebroadcast those signals throughout the areas in which the DAS is installed. The sources can include cellular service from multiple wireless carriers, public safety radio frequencies, and WiFi. If a campus has a medical clinic or hospital, the special medical wireless systems it uses also can be supported. In this article, the author describes how a DAS operates and discusses the three primary downsides to DAS solutions--cost, carrier buy-in, and a lack of standards.
