Direction Finding and Localization with Bluetooth 5.2

The Constant Tone Extension (CTE) function introduced since Bluetooth Low Energy 5.1 greatly improves indoor Bluetooth Low Energy localization. These small, low-energy beacons transmit signals that Bluetooth-enabled devices can use to calculate proximity and positioning. This technology enables continuous navigation, location-based services,...

Robust Bluetooth Low Power Communication

This work presents the first robust connection mode for Bluetooth Low Energy on an energy harvesting sensor.

Bluetooth Ultrasimple Gamepad: Design of a wireless cooperative gaming device

The design, production and testing of the Bluetooth Ultrasimple Gamepad, or BUG for short, is laid out in this report. In the current market, most of the controllers available are multi-button controllers with analogue sticks. These controllers are expensive and can not be used for many web browser games which rely on a keyboard input to work....

Indoor Localization using Narrowband Radios and Switched Antennas in Indoor Environments

Indoor positioning using Bluetooth addressed a great concern. The properties of narrowband usage, low energy consumption and universality on devices attract numerous customers and promote researchers to investigate potential of Bluetooth in indoor positioning field. It has already supported Angle-of-Arrival (AoA) and Angle-of-Departure (AoD) in...

Translating BLE Received Signals across different Smartphones

This report constitutes the final product of my internship, where research was conducted on the differences of the Bluetooth Low Energy signal reception between 2 different phones (p1, p2) and eventually, the possibility of developing a translation function that could be used to predict the signal strength reception of p1, by considering the...

Bluetooth Direction Finding

In the next generation of Bluetooth standard, the Bluetooth SIG wants to incorporate multiple antenna systems into the Bluetooth Low Energy specification to enable direction-finding features. The features are aimed to improve the accuracy of off-the-shelf Asset Tracking Profile (ATP) and Indoor Positioning Service (IPS) including two modes –...

Analysis and Design of a Ring-Oscillator-Based Fractional-N Injection-Locked Digital PLL for IoT Applications

Frequency translation is required in any modern wireless communication systems.<br/>This is in large part due to the fact that the modulated signal is easy to<br/>transmit in radio frequency in the form of an electromagnetic wave, and the demodulated signal is easy to process in the baseband frequency by a powerful digital processor. Frequency...

Smart sensors and communication using Internet of Things in supermarkets: Sensor to Server communication

During 9 weeks of investigation multiple solutions for implementing a communication module in a supermarket have been explored. These results led to three options which have been further researched. Bluetooth Low Energy (BLE), 433 MHz and ZigBee have been selected as the best communication protocols<br/>for sensor to gateway communication. Chips...

A statistical analysis on the system performance of a Bluetooth Low Energy indoor positioning system in a 3D environment

Since GPS tends to fail for indoor positioning purposes, alternative methods like indoor positioning systems (IPS) based on Bluetooth low energy (BLE) are developing rapidly. Generally, IPS are deployed in environments covered with obstacles such as furniture, (partition-) walls, people and electronics influencing the signal propagation. The...

WipLoc: Perpetual Indoor Localization with RF Wireless Power Transfer

Indoor localization is a topic that has been investigated for more than a decade. Yet, no single system exists that is widely adopted as the de facto localization standard. From a research perspective the goal is to obtain a solution that is general, simple and accurate. As the number of devices in the Internet of Things grow, a new set of...

Real Time Localization of Assets in Hospitals using Quuppa Indoor Positioning Technology

Indoor positioning is becoming a hot topic in public areas that are used by large numbers of people. Finding people and assets in buildings has become more difficult because of the complexity and scale of today’s public space. On the subject of locating assets in the hospital the following use case is defined for this project. Positioning and...

GonioTrainer for sport

De GonioTrainer is een systeem dat mensen helpt om een beter inzicht te krijgen in hun bewegingen. Het bestaat uit een sensor module en een feedback module die beide op het lichaam worden bevestigd. Ze worden draadloos uitgelezen en aangestuurd door een smartphone. Er is gekozen voor een Bluetooth Low Energy verbinding tussen de modules en en...

Fundamentals For An Autonomous Zebro Swarm

In this thesis, a swarm is defined as:<br/>”A swarm is a large number of homogenous, unsophisticated agents that interact locally<br/>among themselves and their environment, without any central control or management to<br/>yield a global behaviour to emerge.”<br/>The bigger perspective is to have the units within a swarm operate for a...

Radio Propagation Aided Indoor Localization: Indoor localization by applying Proportionate Measurement Localization (PML) using Bluetooth Low Energy tags

Indoor localization is a hot topic since the demand for Location Based Services (LBS) has increased, especially (semi) public places like museums, office buildings and congress halls would benefit from LBS. Outdoor localization and its applications like navigation systems are well implemented in society and used by many on a daily basis....
