Saldana, J. (author), Ruiz-Mas, J. (author), Almodovar, C.J.L. (author)Frame aggregation is widely used in 802.11 WLANs in order to provide a significant throughput improvement. However, the latency increase that comes as a counterpart can reduce the quality experienced by the users of applications with real-time constraints. This letter explores the throughput versus latency tradeoff in the context of central...article 2017

TNO Defensie en Veiligheid (author), Maas, A.P.M. (author), van Vliet, F.E. (author)This paper describes the design and performance of a low-cost synthesized FMCW radar module, operating in S band. The bi-layer PCB contains a frequency-agile low phase-noise synthesizer and three identical coherent receive-channels. The transmit channel has an automatic power control system that reduces the output power when a large reflection...conference paper 2008

Roijers, F. (author), van den Berg, J.L. (author), Fan, X. (author), Fleuren, M.J. (author), TNO Informatie- en Communicatietechnologie (author)Several studies in literature have investigated the performance of the proposed ieee 802.11e standard for qos differentiation in wlan, but most of them are limited both with respect to the range of the parameter settings and the considered traffic scenarios. The aim of the present study is twofold. First, we systematically investigate the...article 2006

Litjens, R. (author), Roijers, F. (author), van den Berg, H. (author), Boucherie, R.J. (author), Fleuren, M. (author)In this paper we present an integrated packet/flow level modelling approach for analysing flow throughputs and transfer times in IEEE 802.11 WLANS. It captures the statistical characteristics of the transmission of individual packets at the MAC layer and takes into account the system dynamics due to the initiation and completion of data flow...article 2004
