Evaluating indoor positioning errors [PDF]
2015 International Conference on Information and Communication Technology Convergence (ICTC), 2015 With the advent of the indoor positioning field there has been a plethora of different approaches to locating people and assets in indoor environments, each with their own strengths and weaknesses. Despite this, a lot of the metrics used for optimization may contain hidden biases (unintended or neglected) or end up measuring aspects of the solution ...

WiFi-RTT Indoor Positioning [PDF]
2020 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2020 Global navigation satellite systems (GNSSs) can deliver very good position estimates under optimum conditions. However, especially in urban and indoor scenarios with severe multipath propagation and blocking of satellites by buildings the accuracy loss can be very large. Using WiFi for indoor positioning is a common approach because WiFi infrastructure

Beacons for indoor positioning
2017 International Conference on Engineering and Technology (ICET), 2017 This work aims to develop a system for the tracking and control of elderly or handicapped people in an indoor environment. We have developed both a special box using an Arduino board, and a mobile application on Android to determine the location of the target based on the Bluetooth Low Energy signals transmitted by special Beacons which are placed in ...
