This paper focuses on the positioning of Wi-Fi nodes in multi-floor indoor environments. A
target radio-frequency (RF) fingerprint–measured by the MS to be localized–is compared …

Vehicular communication and sensing technologies are key to enabling 6G Intelligent
Autonomous Transportation Systems (IATS). With the introduction of massive sensors and …

Bridges that cross a railway's right-of-way are one of the most common obstacles for wave
propagation along a highspeed railway. They can lead to poor coverage or handover failure …

For upper extremity rehabilitation, quantitative measurements of a person's capabilities
during activities of daily living could provide useful information for therapists, including in …

We present a method to estimate the coverage areas of transmitters, and a method to use a
database of such coverage areas for personal positioning. The coverage areas are …

This chapter presents the principles of radio frequency (RF) fingerprinting methods, also
known as database correlation methods (DCMs). Although there is a wide variety of DCM …

It is well-known that the performance of radio frequency fingerprinting is strongly dependent
on the variation of the received strength signal indicator (RSSI), that can be caused by …

This work examines the use of genetic algorithms (GAs) to optimise two different problems
regarding positioning applications in wireless communication systems. The first problem …

Radio Frequency Fingerprinting estimates the mobile station location by comparing a
measured radio frequency fingerprint with a set of previously collected or generated …

Database correlation methods (DCM) are used to locate mobile stations (MS's) in wireless
networks. A target radio-frequency (RF) fingerprint-measured by the target mobile station-is …
