As the world leader in secure connectivity solutions for embedded applications, we are driving innovation in the secure connected vehicle, end-to-end security & privacy and smart connected solutions markets.
Modern cars are equipped with a passive keyless entry & start (PKES) system which allows users to access and start the car without actively using the key fob. Existing systems use a combination of two technologies: a low-frequency (LF) magnetic field to determine the location of the fob (ranging), and an ultra-high radio frequency (UHF/RF) link to establish communication between fob and car. Because LF magnetic fields remain largely undisturbed by environmental factors including human body effects, the fob location can be accurately determined by measuring the received field strength (RSSI).
Given the ubiquity of smart devices (phones, watches, etc.) there is a shift towards smart car access systems, with LF/UHF being replaced by existing RF technologies. Due to its wide availability in smart devices, Bluetooth is one of the potential RF technologies for a PKES system where it will be used for both ranging and communication between device and car. In addition to using RSSI and time of flight, ranging information can be obtained from phase shifts induced at multiple carrier frequencies.
In this master thesis you will investigate algorithms for carrier phase-based ranging and assess their applicability to smart car access using Bluetooth.
For the successful completion of the Master Thesis you will receive a remuneration of a one-time payment of EUR 5.150, - gross. Additional you will get a bonus of EUR 2.000, - gross if you receive an excellent grade "Sehr gut" for your Thesis.
