This one-hour course explains the how LEED building design and construction materials impact inbuilding wireless coverage. The course examines the impact of green building materials – Low-E glass, new cement mixtures, etc – can result in decreased wireless coverage. The course recommends alternatives – including the use of distributed antenna systems (DAS) – to ensure ubiquitous wireless coverage for LEED building tenants. The course also uses a case study of a successful LEED/inbuilding implementation to illustrate the topic. More than 96 percent of the U.S. population use cell phones and wireless devices, and 70 percent of wireless voice and data connections take place indoors. Add to that the requirements of first responders (police, fire and EMS) who demand ubiquitous in-building radio coverage to ensure public safety. In this session, you will learn how distributed antenna systems (DAS) are a viable meansto solving coverage issues to ensure reliable in-building wireless services.
