Passive Indoor People Counting Using Bluetooth LE

The new paper Passive Indoor People Counting by Bluetooth Signal Deformation Analysis with Deep Learning, proposes a method for counting people in indoor spaces using Bluetooth Low Energy (BLE) signals and deep learning techniques. The goal is to offer a privacy-preserving, device-free, and non-intrusive solution for occupancy monitoring in environments where camera use is inappropriate, … Continue reading “Passive Indoor People Counting Using Bluetooth LE”

Matching Industrial Assets and Their Operators

Recent research looks into a new method for linking industrial assets, like power tools, with their operators using low-power Internet of Things (IoT) devices based on Bluetooth Low Energy (BLE). Despite the wide adoption of asset-tracking technologies, there’s still no widely used solution for dynamically identifying which worker is using which tool. This is important … Continue reading “Matching Industrial Assets and Their Operators”

Using Bluetooth Beacons for In-Place Ageing

A new study describes an indoor‑positioning system built around Bluetooth Low Energy. Each room receives a mains‑powered beacon that houses an ESP32 micro‑controller running BLE in advertising mode, together with motion, ultrasonic, light and temperature sensors. Older adults wear a low‑cost tag or smartwatch that periodically transmits its identifier. Beacon modules report the relative signal … Continue reading “Using Bluetooth Beacons for In-Place Ageing”

Testing if a Beacon is Working

It’s often the case you need to know if a beacon is working and advertising the correct information. It’s also sometimes necessary to differentiate between beacons, based on their signal strength, so you know you are setting up the correct beacon. Other times, you might want to know a beacon’s MAC address. The best scanning … Continue reading “Testing if a Beacon is Working”

Auto-Adjusting Location Algorithm

A new study uses an indoor localisation system that integrates Bluetooth Low Energy (BLE) with an Internet of Things (IoT) framework to improve accuracy in tracking individuals, particularly those with cognitive impairments such as Alzheimer’s and dementia. The system employs an auto-adjusting algorithm that dynamically optimises received signal strength indicator (RSSI) coefficients based on real-time … Continue reading “Auto-Adjusting Location Algorithm”

Using Support Vector Regression (SVR) with Beacons

A new study (pdf) explores optimising Bluetooth Low Energy (BLE) beacon-based indoor positioning systems using support vector regression (SVR). It addresses the challenge of accurately identifying building occupants’ locations in real time, a critical requirement for applications such as emergency evacuations and asset tracking. Traditional methods, including trilateration and RSSI-based techniques, can face limitations like … Continue reading “Using Support Vector Regression (SVR) with Beacons”

Improving Bluetooth Location Accuracy

New research focuses on enhancing indoor localisation using Bluetooth Low Energy (BLE) technology by addressing challenges in signal instability and noise. The authors propose a system combining the Kalman filter for signal smoothing and deep learning models, specifically Autoencoders and Convolutional Autoencoders, for feature extraction from Received Signal Strength Indicator (RSSI) data. The method uses … Continue reading “Improving Bluetooth Location Accuracy”
