Bluetooth Tracking without Discoverability,able. Bluetooth has been identified as a potential location technology that mobile consumer devices already support, easing deployment and maintenance. However, Bluetooth tracking systems to date have relied on the Bluetooth inquiry mode to constantly scan for devices. This process is very slow and

Error Estimation for Indoor 802.11 Location Fingerprinting,most of the research focused on the calculation of position estimates. In this paper, we go a step further and investigate how the position error that is inherent to 802.11-based positioning systems can be estimated. Knowing the position error is crucial for many applications that rely on position i

Daily Routine Recognition through Activity Spotting,ities and simple classifiers based on their statistics allows to train a discriminative classifier for daily routine activities such as working and commuting. Using a recently published data set we find that the number of required low-level activities is surprisingly low, thus, enabling efficient al

SofTOA: Software Ranging for TOA-Based Positioning of WLAN Terminals,uirement for hardware modifications in the WLAN device in order to achieve accurate ranging. This paper presents an approach that overcomes this limitation. It is based on RTT measurements performed through time-stamping the transmission and reception of IEEE 802.11 MAC frames from the WLAN driver’s
