Out of the shadow: Long term cost development of intelligent sensor networks

The paper addresses intelligent sensor networks (ISNs) as a special version of networked wireless robotics. The success of these networks is partly explained by the technical advances, but as well by cutting down costs of these networks. Using a functional breakdown of intelligent ISNs, the trends of the various functions are discussed. The...

On Managed Services Lanes and their Use in Home Networks

Home networks show an increasing level of heterogeneity regarding the devices connected, network technologies used, and services supported. Heterogeneity inhibits quality assurance for new services, such as online gaming, energy management, and health care. This paper focuses on the role that the concept of Managed Services Lanes (MSLs) plays in...

Downlink Resource Allocation for Evolved UTRAN and WiMAX Cellular Systems

The future broadband wireless cellular systems evolved UTRAN (E-UTRAN) and WiMAX are receiving a lot of interest in recent years. Both systems deploy orthogonal frequency division multiplex (OFDM) physical layer consisting of large number of mutually orthogonal sub-carriers. This physical layer provides high robustness against multi-path effects...

Looking for new DNA: The world around IMT-advanced

Technology, such as IMT-2000 and IMT-A, plays an important role in our society. A number of prominent authors and thinkers have judged the impact of technology as being increasingly radical. This paper connects different visions on technology, thereby bringing different perspectives on innovation into line. An important motivation for this paper...

RF impairments in high-rate wireless systems - understanding the impact of TX/RX-asymmetry

Dealing with radio frequency (RF) front-end impairments will be one of the major design challenges for next-generation wireless communication systems due to conflicting requirements, such as high data rate, low cost and low power consumption. The use of digital compensation of the imperfections appears a very promising method to meet...

Joint impact of quantization and clipping on single- and multi-carrier block transmission systems

This work investigates the joint impact of quantization and clipping, caused by analog-to-digital converters (ADCs) with low bit resolutions, on single- and multi-carrier block transmission systems in wireless multipath environments. We consider single carrier block transmission with frequency domain equalization (SC-FDE) and the multi-carrier...

Wireless network simulation - Your window on future network performance

The paper describes three relevant perspectives on current wireless simulation practices. In order to obtain the key challenges for future network simulations, the characteristics of "beyond 3G" networks are described, including their impact on simulation. © Springer 2005.

Power control with antenna array processing for UMTS

The benefits of employing antenna array processing for the interference limited UMTS system is the increase in the number of simultaneous users and the reduction in the transmitted uplink power. The joint power control and antenna processing offers maximum achievable capacity with lower transmission powers for the given target SINR (signal-to...

Mobiele data verbeterde hun business performance – hoe zit dat bij u?

Het staat buiten kijf dat ICT en mobiele data vrijwel elke industriële sector zullen beïnvloeden, ongeacht of het fysiek-intensief of kennis-intensief is. Het beïnvloedt de wijze, plek, en de tijd van actie, en te oordelen naar de weinige succesvolle voorbeelden vergt het een vooruitziende blik en grote bekwaamheid om de verandering zodanig te...
