TRBOnet is Motorola MOTOTRBO 2-way radio control room software. The system uses GPS outside and beacons indoors. The handsets detect iBeacon advertising that shows on TRBOnet plans or maps in the control room. Here are some tips for setting up beacons for TRBOnet: Each beacon has a unique UUID, major and minor values. Change the … Continue reading “TRBOnet Beacon Setting Tips”
There’s recent research on Active Aging in Place Supported by a Caregiver-Centered Modular Low-Cost Platform (pdf) by João Paulo Rangel Marques Capinha of Nova School Of Science And Technology, Portugal. Aging in place is where the elderly reside in their own homes rather than being taken into care. A platform is proposed that supports aging … Continue reading “Aging in Place Assisted by Bluetooth Beacons”
There’s new research from the Department of Electrical Engineering, University of North Texas, USA on Measurement and Analysis of RSS Using Bluetooth Mesh Network for Localization Applications. The paper explains how received signal strength (RSSI) based solutions have accuracy limitations in radio multipath (radio reflective) environments. It describes a solution that improves accuracy using Bluetooth … Continue reading “Using Bluetooth Mesh and Space, Time, Frequency Diversity to Improve Locating Accuracy”
There’s recent research on Managing Crowded Museums: Visitors Flow Measurement, Analysis, Modelling, and Optimization. The aim of the research was to provide suggestions to a museum’s curators to better manage visitors flows to increase visitor comfort and improve safety. The museum for the case study was Galleria Borghese museum in Rome, Italy that has no … Continue reading “Measuring Crowded Museums Using Bluetooth Beacons”
There’s new research by ITMO University, Russia on the Implementation of Indoor Positioning Methods: Virtual Hospital Case. The paper describes how positioning can be used to discover typical pathways, queues and bottlenecks in healthcare scenarios. The researchers implemented and compared two ways to mitigate noise in Bluetooth beacon RSSI data. The probabilistic and neural network … Continue reading “Probabilistic vs Neural Network iBeacon Positioning”
There’s new research by the Institute of Information Science and Technologies, Pisa, Italy on Detecting Proximity with Bluetooth Low Energy Beacons for Cultural Heritage. The paper starts by describing alternative technologies including Ultra-wideband (UWB), Near Field Communication (NFC) and vision. The RE.S.I.STO project allows media on the medieval town of Pisa to be accessible via … Continue reading “Detecting Proximity Using Bluetooth Beacons in Museums”
We previously mentioned how cost, battery life and second sourcing are the main advantages of Bluetooth over Ultra-Wideband (UWB). An additional, rarely mentioned, advantage is scalability. Servers that process Bluetooth or Ultra-Wideband support a particular maximum throughout. The rate at which updates reach systems depends on the number of assets, how often they report and … Continue reading “Bluetooth (BLE) vs Ultra-Wideband (UWB) for Locating”
There’s a new paper from the journal Telkomnika Telecommunication, Computing, Electronics and Control on Smartphone indoor positioning based on enhanced BLE beacon multi-lateration (pdf). The paper by Ngoc-Son Duong of Vietnam National University describes a relatively simple method to improve location accuracy. The paper starts by describing trilateration and the author voices the opinion that … Continue reading “Using Multi Bluetooth iBeacon Trilateration For Increased Accuracy”
There’s a new article from the Icontech International Journal of Surveys, Engineering, Technology on Indoor Position Routing (IPR) and Data Monitor Using Bluetooth Low Energy Technology by researchers at the Hasan Kalyoncu University, Institute of Science, Electrical & Electronics Engineering, Gaziantep, Turkey. This article is different because it considers navigation as opposed to just locating. … Continue reading “Indoor Navigation Using Bluetooth LE”
There’s a recent paper Review of Indoor Positioning: Radio Wave Technology that provides a great overview of indoor positioning technologies. From a hardware perspective it covers, RFID, UWB, Bluetooth, ZigBee, IR, WiFi, ultrasonic and hybrid systems. There’s a useful comparison table of the various technologies: The paper describes methods of using radio signals to determine … Continue reading “Learn About Indoor Positioning”
