Finding the Nearest Beacon

There’s new research from Faculty of Electrical Engineering and Computer Science, University of Maribor, Slovenia on Improved Bluetooth Low Energy Sensor Detection for Indoor Localization Services. While there has been lots of research into server-side processing to improve location accuracy, this research instead looks into improving accuracy locally, in terms of finding the nearest beacon. … Continue reading “Finding the Nearest Beacon”

Bluetooth Myths and Facts

There’s a useful new webinar at the Bluetooth SIG on The Myths & Facts About Bluetooth® Technology as a Positioning Radio. Fabio Belloni from Quuppa explains the main Bluetooth myths and facts: Performance – There are misconceptions about accuracy, latency and reliability brought over from older systems using only received signal strength (RSSI). Newer systems … Continue reading “Bluetooth Myths and Facts”

Cisco and Aruba Based Real Time Location Systems (RTLS)

A growing number of WiFi access point vendors such as Cisco and Aruba are offering Real Time Location Systems (RTLS). While using existing hardware might seem compelling, it’s sometimes not practical. Here are some questions to be answered when considering such systems: Does your site have access points from mixed vendors? If so, the RTLS … Continue reading “Cisco and Aruba Based Real Time Location Systems (RTLS)”

Aging in Place Assisted by Bluetooth Beacons

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”

Using Bluetooth Mesh and Space, Time, Frequency Diversity to Improve Locating Accuracy

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”

Measuring Crowded Museums Using Bluetooth Beacons

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”

Probabilistic vs Neural Network iBeacon Positioning

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”

Detecting Proximity Using Bluetooth Beacons in Museums

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”

Bluetooth (BLE) vs Ultra-Wideband (UWB) for Locating

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”
