The provisioning of wireless data services in the railway environment will become increasingly important for train operators and train constructors in the upcoming years. A well-founded choice of the technology to be used for the outdoor network connection is investigated in this paper. Several wireless technologies - including HSPA, E-UTRA and WiMAX - are compared by calculating their wireless ranges...
The power consumption of wireless access networks will become an important issue in the coming years. In this paper the power consumption of base stations for mobile WiMAX, fixed WiMAX and UMTS is modelled. This power consumption is evaluated in relation to the coverage. For a physical bit rate of 2 Mbps, a power consumption of approximately 5600 W and a range of 1 km is obtained with UMTS. Fixed...
In the (mobile) communications domain, Quality of Experience (QoE) has become the ultimate metric influencing the success or failure of new applications and services. Since it is increasingly argued in the literature that QoE should be seen as a multi-dimensional concept, this paper focuses on QoE from an interdisciplinary perspective. In this paper, we discuss a framework that can be used for the...
