Item Performance of PLC communications in frequency bands from 150 kHz to 500 kHz(Institute of Electrical and Electronics Engineers Inc., 2017-04-11) Arechalde, Ibon; Castro, Marta; Garcia-Borreguero, Ibone; Sendín, Alberto; Urrutia, Iker; Fernandez, Ainara; Tecnalia Research & Innovation; Generales; Datos y ProtocolosOne of the most common communications technologies being used as the media to access the meters in Smart Metering deployments is Narrowband Power Line Communications (NB-PLC), mainly in Europe but also in other places. Most of the systems available in the market under NB-PLC are extending the frequency bands used in order to increase their bandwidth and avoid interferences from other devices in the network. This paper presents results obtained in real-field tests performed by Iberdrola and Tecnalia in an urban LV distribution network representative of this kind of installations in Europe. The objective of the tests is to verify the performance of a NB-PLC technology using frequency bands from 150 kHz to 500 kHz. The tests have been developed in several points of the same LV distribution network, checking point to point connections among them. Apart from the performance of the different links, the noise levels measured at the reception points have been also analyzed.Item Understanding soundscape as a specific environmental experience: Highlighting the importance of context relevance(2011) Aspuru, Itziar; Garcia, Igone; Herranz-Pascual, Karmele; Garcia-Borreguero, Ibone; CALIDAD Y CONFORT AMBIENTAL; ADAPTACIÓN AL CAMBIO CLIMÁTICO; Datos y ProtocolosA conceptual model about environmental experience is presented to guide soundscape studies. This proposal combines the state of the art and the experience of Tecnalia regarding psychosocial studies which focuses on the relationship between environment and people. The model has been structured around five main elements: person (community), place, activity, previous interaction between person and place, and environmental experience. The environmental experience is understood as a holistic experience not only within that soundscape but also linked to other perceptions, such as landscape, odour, etc. The relevant factors and variables of each main element have been identified to assist us in describing human and social holistic experience in relation to the place, in general, and soundscape (perception) in particular. The main objective of this paper is to analyze conceptually and throughout a field experiment, the relevance of the context, understanding it as the surrounding circumstances of the environmental experience. Hence, a field experiment is presented to analyze the relevance of a context characteristic, namely sound environment on the global environmental experience.
