There’s new research from University of Catania, Italy on A Perspective on Passive Human Sensing with Bluetooth. The research identifies and discusses the factors and operating conditions that can result in varying accuracy. The paper explains the advantages of Bluetooth over WiFi for passive human sensing. It also discusses the advantages and disadvantages of RFID, … Continue reading “Passive Human Sensing Using Bluetooth”
As previously mentioned, we perform signal strength and stability tests across beacons. The data feeds into our consultancy work. Here are some high level observations. The following graph shows the standard deviation of the RSSI @ 1m, for some of our beacons, measured over a 60 second time period: Smaller bars are better and represent beaconswhose … Continue reading “Beacon Signal Stability Observations”
There’s new research from Universities in Piraeus, Greece and Berlin, Germany, together with U-Blox AG in Switzerland who create Bluetooth Angle of Arrival prototyping boards on Deep Learning-Based Indoor Localization Using Multi-View BLE Signal. Processing of Bluetooth Angle of Arrival usually requires radiogoniometry spectral analysis of radio in-phase and quadrature-phase (IQ) signals in order to … Continue reading “Using AI Machine Learning with Bluetooth Angle of Arrival (AoA)”
There’s useful research by Sindhumol S of Cochin University of Science and Technology, India on Implementation and Analysis of a Smart Team Management System using iOS Devices as iBeacon. The system provides location-based task monitoring and presence detection. Task details and announcements are available when a team member enters the range of an iBeacon broadcast. … Continue reading “Using iBeacon for Team Management”
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”
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”
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)”
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”
