—New automated solutions are needed, e.g., in mining industry to improve efficiency and productivity of every process. In addition, costs have to be reduced, and health and safety of employees need to be enhanced. This paper studies vehicle-to-vehicle (V2V) communication to be utilized in, e.g., mining vehicles in a tunnel to increase safety and(More)
This paper presents the results of a coexistence study investigating the impact of ultra-wideband (UWB) interference on IEEE 802.11b and Bluetooth networks. The results are based on the experimental test measurements made at the University of Oulu, Finland. Simple high-power UWB transmitters are used to interfere with victim networks. Preliminary results(More)

—Wireless communications are increasingly-often selected as a cable replacement for on-board vehicular networks. When a wireless technology implements safety critical application , cryptographic countermeasures are required. This paper describes the impact of security on intra-vehicular communication in a real tunnel scenario, e.g. for urban transit or(More)
—Wireless local area networks (WLANs) gained ever-growing importance in public transportation systems where they are selected to reduce installation costs and introduce new services. However, the introduction of a wireless interface in safety critical applications implies different communication protocol analysis and the introduction of a security layer is(More)
An experimental evaluation of 802.11g+n based wireless local area network (WLAN) devices with omnidirectional and directive antennas under interference is investigated in this paper. The performance of directive antennas is known to be better if the interference signal is coming from the sidelobes' directions. Here we studied the performance difference(More)
