The Radio Sector of the ITU (ITU-R) has been involved in two aspects of personal mobile communication systems, namely defining the standards and identifying frequency bands related to these systems under the label of the International Mobile Telecommunication (IMT). This paper has investigated...

Der vorliegende Beitrag analysiert die Vor- und Nachteile alternativer Allokationsmechanismen für das 900- und 1800-MHz-Frequenzspektrum, dessen Nutzungsrechte Ende 2016 auslaufen. Im Wesentlichen bestehen zwei Optionen. Zum einen die Möglichkeit der Verlängerung der aktuellen Nutzungsrechte,...

As demand for mobile broadband services continues to explode, mobile wireless networks must expand greatly their capacities. This paper describes and quantifies the economic and technical challenges associated with "deepening" wireless networks to meet this exploding demand. Methods of capacity...

The digital dividend is the amount of spectrum that is freed up by the switch over from analogue TV to digital terrestrial TV in the UHF band. Drawing from a research project (Braulke et al. 2010) commissioned by the Austrian regulator RTR, this article prioritizes, analyses and evaluates the...

This paper presents the development and technical concepts of radio frequency identification (RFID) as well as requirements of document logistics. Combining the two topics possibilities of implementing RFID technologies in document logistics (in finance) are discussed. This highlights the future...

Today wireless network connections gain more and more importance. Yet a drawback of this technology is the higher packet error rate compared to wired networks. This has a negative impact on SCTP associations as packet loss is considered a congestion indication. The SCTP extension PKTDROP reacts...
