About The Job

Empirical Evaluation of Wireless Connectivity in Essity’s IoT Systems: Towards Enhanced Reliability and Efficiency

At Essity we have IoT solutions on the market for the last 12 years, we have gone through several technology shifts, but one challenge is still the same, how do we optimize our IoT solutions for indoor use, the radio challenges are still the same no matter what technology we use. We are constantly working to improve our solutions. We are looking for fresh perspectives on this challenge.

Are you a student eager to apply your theoretical knowledge to real-world challenges? We believe that innovation thrives on new ideas, and your master thesis project could be the spark that drives our next breakthrough.

Your Role

You will dig deep into our different IoT solutions, applying your theoretical knowledge to analyze our existing solutions in their right element and look for improvements. How do we know if our solution will work in a new location, do we have the optimal antenna design, are we using the best technology for our use cases?

Background

Our solutions have been on the market for a long time and we have been doing incremental improvements and learned a lot, but the radio part remains a challenge.

Project

Do analysis with focus on Essity's use-cases, technical evaluations of different IoT technologies applicable for our various use-cases.

You need to be structured, analytic, have a good understanding of various wireless connectivity technologies like LTE-M, NB-IoT, 4G, 5G, Wi-Fi, LoRa etc.

How to evaluate a site, indoor, from a radio perspective before and during production. Can we lower the installation costs by shorten the installation time, “First time right” How to monitor the radio environment over time. Can we build our own “Indoor coverage map” (we have a lot of old data…) Can we rebuild one of our devices to use as a site planning tool, instead of buying a product on the market, we believe it is an advantage to use our own antenna and modem.

Your Profile

Number of students: preferably 2
