Evaluate Techniques For Wireless Communication From a Network Device To a Smartphone

Abstract: This is our thesis for the course Degree Project in Electronics and Computer Engineering (IL122X). Our project was carried out at the company Westermo which is working on making industry network equipment. Westermo wanted a method for sending information from one of their network devices to a mobile device using secure wireless communication. It was first planned to be done using Bluetooth, and exchange keys through NFC. This was later changed to not just evaluate this particular situation, but to evaluate the best solution for their use-case. This report will go through our evaluation process. We will mention different possible techniques and if they can be used, then put the techniques together and form a possible solution. Our discussion will mention what we think is the best solution and why, and the way forward.
