Intorduction: | BouWatch develops systems for securing construction sites. The core product are mobile camera masts that are placed at the site. The cameras are capable of detecting trespassing and producing an alarm that is sent to a control room for validation and follow-up. At such sites, a range of valuable manual tools is commonly in use. Equipping these tools with Bluetooth (BLE) beacons becomes increasingly popular. The recent 5.1 version of BLE allows locators to apply direction finding based on Angle of Arrival (AoA). This provides an opportunity to locate BLE devices, i.e., pinpoint locations of construction tools on site. An initial research project investigated algorithms for BLE AoA estimation using an off-the-shelf linear antenna array. The project showed that the BLE AoA technology can provide an estimate of the angle with a reasonable accuracy for distances that are relevant to the BouWatch use case. The research also showed important shortcomings in the tested solution that relate to the antenna array. The project assumed a linear array. Such an array is limited to estimating the angle of arrival in a single (half)-plane, typically the azimuth angle. The use case however requires the angle to be estimated in two dimensions, both in the azimuth and elevation. This, in turn, requires a two- dimensional antenna array. |
Description: | The purpose of this assignment is to develop a solution for simultaneously estimating the azimuth and elevation of a BLE device using the BLE AoA technology. Some elements of this assignment are:
This assignment is conducted in close cooperation with the BouWatch research and development department.

Requirements: | You need MATLAB coding skills. You are either familiar with basic antenna design and software (like HFSS) or willing to learn these. |
