Enabling Location Awareness with a SMILE

Project Type: Master/Diploma Thesis
Project Status: Open

DW1000_framework

Short Description

A key concept of future wireless technologies involved in 5G and the Internet of Things (IoT) is location awareness. With a large number of devices communicating wirelessly, the notion of these devices being aware of their surroundings is a beneficial, if not a necessary, state to achieve.

In the TU Graz LEAD project 'Dependable Internet of Things', the wireless subgroup has developed the 'SMILE' antenna which is capable of transmitting at high frequencies and bandwidths, while also concentrating the transmission into a certain direction. On top of that, the SMILE has a reasonably small size which makes it an attractive option to use in practical implementations based on commercially available transceiver technology. The directionality together with the high bandwidth capabilities of the antenna are promising features to perform positioning methods. In this regard, a framework was created based on the low-cost DW1000 frontend (see picture), allowing to perform indoor positioning in a static indoor environment with known floorplan reaching decimeter level accuracy while only using a single anchor / base station.

The aim of this thesis is to build on top of the existing framework including the SMILE antennas to act as the 'eyes' or 'voice' of the device. Possible things to investigate are non-static scenarios with moving devices (tracking filters) or environment mapping, however there are countless further possibilities that can be discussed.
