A 3D ray launching time-frequency channel modeling approach for UWB ranging applications
Otim, Timothy
; López Iturri, Peio 
; Azpilicueta Fernández de las Heras, Leyre ; Bahillo, Alfonso; Falcone Lanas, Francisco Javier (IEEE, 2020)
Artículo / Artikulua 
Ultrawideband (UWB) has the ability to achieve decimetre level of ranging accuracy, hence, its wider usage nowadays in the field of positioning. In spite of the attractiveness of UWB, its performance is strongly dependent ... -
Effects of the body wearable sensor position on the UWB localization accuracy
Otim, Timothy; Díez, Luis E.; Bahillo, Alfonso; López Iturri, Peio ; Falcone Lanas, Francisco Javier (MDPI, 2019)
Artículo / Artikulua
Over the years, several Ultrawideband (UWB) localization systems have been proposed and evaluated for accurate estimation of the position for pedestrians. However, most of them are evaluated for a particular wearable sensor ... -
FDTD and empirical exploration of human body and UWB radiation interaction on TOF ranging
Otim, Timothy; Bahillo, Alfonso; Díez, Luis E.; López Iturri, Peio ; Falcone Lanas, Francisco (IEEE, 2019)
Artículo / Artikulua
In time-of-flight (TOF)-based human ranging systems, target sensors are often mounted on or close to the human body, which may raise non-line-of-sight (NLOS) cases and lead to significant ranging errors depending on the ... -
Impact of body wearable sensor positions on UWB ranging
Otim, Timothy; Bahillo, Alfonso; Díez, Luis E.; López Iturri, Peio ; Falcone Lanas, Francisco Javier (IEEE, 2019)
Artículo / Artikulua
In recent years, Ultrawideband (UWB) has become a very popular technology for time of flight (TOF) based localization and tracking applications but its human body interactions have not been studied yet extensively. Most ... -

Artículo / Artikulua
In this paper, intra-wagon wireless communication performance is analyzed, in order to account for inherent scenario complexity in the deployment phase of wireless systems toward the implementation of a context-aware ... -
Towards sub-meter level UWB indoor localization using body wearable sensors
Otim, Timothy; Bahillo, Alfonso; Enrique Díez, Luis; López Iturri, Peio ; Falcone Lanas, Francisco Javier (IEEE, 2020)
Artículo / Artikulua
Thanks to its ability to provide sub-meter level positioning accuracy, Ultrawideband (UWB) has found wide use in several wireless body area network (WBAN) applications such as ambient assisted living, remote patient ... -
Ubiquitous connected train based on train-to-ground and intra-wagon communications capable of providing on trip customized digital services for passengers
Salaberria, Itziar; Perallos Ruiz, Asier; Azpilicueta Fernández de las Heras, Leyre ; Falcone Lanas, Francisco Javier ; Carballedo, Roberto; Angulo Martínez, Ignacio; Elejoste Larrucea, Pilar; Bahillo, Alfonso; Astrain Escola, José Javier ; Villadangos Alonso, Jesús (MDPI, 2014)
