Location Fingerprinting With Bluetooth Low Energy Beacons
Ramsey Faragher,Robert Harle +1 more
TL;DR: This work provides a detailed study of BLE fingerprinting using 19 beacons distributed around a ~600 m2 testbed to position a consumer device, and investigates the choice of key parameters in a BLE positioning system, including beacon density, transmit power, and transmit frequency.
Understanding the Basis of the Kalman Filter Via a Simple and Intuitive Derivation
TL;DR: This article provides a simple and intuitive derivation of the Kalman filter, with the aim of teaching this useful tool to students from disciplines that do not require a strong mathematical background.
An Analysis of the Accuracy of Bluetooth Low Energy for Indoor Positioning Applications
Ramsey Faragher,Robert Harle +1 more
TL;DR: It is determined that the optimal positioning performance is provided by 10Hz beaconing and a 1 second multipath mitigation processing window size, and above this there is no clear benefit to extra beacon coverage.

Understanding the Basis of the Kalman Filter Via a Simple and Intuitive Derivation [Lecture Notes]
TL;DR: In this paper, a simple and intuitive derivation of the Kalman filter is presented, with the aim of teaching this useful tool to students from disciplines that do not require a strong mathematical background.
Proceedings ArticleDOI
Opportunistic radio SLAM for indoor navigation using smartphone sensors
TL;DR: This paper provides the experimental results of a system utilising only the sensors available on a smartphone to provide an indoor positioning system that does not require any prior knowledge of floor plans, transmitter locations, radio signal strength databases, etc.
