Article
Accés restringit per política de l'editorialTime of Arrival (TOA) based techniques are expected to overcome performance limitations of existing WLAN positioning approaches. The upcoming IEEE 802.11v standard is expected to play a key role because it will include new ... -
Contributions to TOA-based location with wlan
Ciurana Adell, Marc (Universitat Politècnica de Catalunya, 2010-07-15)
Tesi
Accés obertLocation techniques that satisfy the requirements of advanced Location-Based Services (LBS) in environments where GPS fails are needed, therefore accurate indoor positioning is becoming increasingly important. This PhD ... -
Enhanced vehicle navigation unit with wifi 802.11 ranging and communication capabilities
Tappero, Fabrizio; Ciurana Adell, Marc; Batlle, Jordi; Uijt de Haag, Maarten; Martín Escalona, Israel; Fernández Fernández, Daniel (2012)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper discusses the implementation of a modified IEEE 802.11 transceiver that is employed to enhance the positioning capabilities of a traditional vehicle on-board navigation unit (OBU). In this paper, we propose ... -
Fusion of WLAN and GNSS observables for positioning in urban areas: the position ambiguity
Fernández, Daniel; Barceló Arroyo, Francisco; Martín Escalona, Israel; Ciurana Adell, Marc; Jofre, Martí; Gutiérrez, Esteban (2011)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper proposes a positioning method that combines GPS pseudoranges and WLAN ranges when less than four GPS satellites are within sight. To enhance the positioning availability, a tight hybridization approach with both ... -
Impacto del modelo de error en distancia en la simulación de sistemas de localización
Guardiola, Salvador; Martín Escalona, Israel; Barceló Arroyo, Francisco; Ciurana Adell, Marc (2010)
Comunicació de congrés
Accés obertLas redes inalámbricas han favorecido enormemente el interés de los usuarios, proveedores de servicio y operadores de red en el posicionamiento geográfico. Como consecuencia, se han propuesto mecanismos en la mayor parte ... -
Indoor tracking in WLAN location with TOA measurements
Ciurana Adell, Marc; Barceló Arroyo, Francisco; Cugno, Sebastiano (ACM, 2006-10-01)
Text en actes de congrés
Accés obertAuthors presented recently an indoor location technique based on Time Of Arrival (TOA) obtained from Round-Trip-Time (RTT) measurements at data link level and trilateration. This new approach uses the existing IEEE 802.11 ... -
