Zusammenfassung

Immobilieninvestoren verlangen heute immer leistungsstärkere technische Infrastrukturen in Gebäuden, um am Markt konkurrenzfähig zu bleiben und den Benutzern höchsten Komfort bieten zu können. Um die leistungsfähige Konvergenz von Telefonie (SIP VoIP), Internet über WLAN und digitalem TV zu zeigen, wird in dieser Publikation das Zusammenspiel verschiedener Last Mile Access-Technologien (WLAN, FSO, Glasfaser) in Verbindung mit hoch (HDTV) und niedrig auflösenden (SDTV) Multimediasignalen im Zuge eines Testaufbaus dargestellt und im Feldversuch geschildert. Es werden die Vor- und Nachteile der einzelnen Technologien in der Praxis dargelegt und erörtert.

Summary

Nowadays real estate investors request more and more high-performance buildings to be competitive on the market and to deliver the highest convenience to its users. To present the convergence of telephony (SIP VoIP), Internet services over WLAN and digital TV this paper shows the interaction of state-of-the-art last mile access technologies (WLAN, FSO, fiber optics) in combination with high (HDTV) and low (SDTV) resolution multimedia signals during a test setup. Advantages and disadvantages of the used technologies in this special case will be shown and discussed.
