Why is Ericsson a good place to work?

Ericsson enables communications service providers to capture the full value of connectivity. The company's portfolio spans Networks, Digital Services, Managed Services, and Emerging Business and is designed to help our customers go digital, increase efficiency, find new revenue streams, and create new user experiences. Ericsson's investments in innovation have delivered the benefits of telephony and mobile broadband to billions of people around the world ensuring our solutions - and our customers - are at the forefront of innovation. We support networks that connect more than 2.5 billion subscribers. With over 100,000 employees and customers in 180 countries, we combine global scale with technology and service leadership. 40 percent of the world's mobile traffic is carried over an Ericsson network. And, our Technology for Good and Connect to Learn programs include creating technology that makes it easier to save lives, feed societies, bring technology to emerging markets and connectivity to remote areas, and grow businesses and prosperity.

At Ericsson, we give our employees the freedom to think big and navigate their career, on a global scale. We create technology that helps others, from helping people enjoy their favourite content to helping people recover from natural disasters by enabling better communications between rescue workers. Your ideas and innovations can turn into achievements that impact society and change the world, creating new connections, new possibilities, and new capabilities. We find that Ericsson is at its best when we bring together the diverse skills of our people. Working across business areas, across cultures, across geographical borders, across technical disciplines. More often than not, across ground-breaking solutions. Next generation technology can be staggeringly complex. But the simpler it is to use; the more people benefit from it. Join us and help build technology that makes it simple to connect with information, business, societies, and each other.

Our Exciting Opportunity

Wireless communication aims toward providing ubiquitous connectivity which can meet a range of use cases and scenarios. The industry 4.0 vision describes a use case for smart connected factories. This use case requires stationary machines, sensors and devices to be connected but also moving objects such as drones, mobile robots and humans. This allows flexible manufacturing setups not bound by cables and factories that are fully automated. Stringent requirements on the radio access technology used in these environments are necessary as both latency and reliability become key for the viability of the new use case.

The Wi-Fi Alliance has published a new Wi-Fi version 6 containing features allowing Wi-Fi access points to schedule transmissions and simultaneously serve multiple users. Additionally, new unlicensed spectrum in the 6 GHz band has been made available totaling 1.2 GHz of spectrum. By employing accurate frequency planning in combination with these new features Wi-Fi networks can provide a more controlled environment with less unpredictability compared to previous generations of Wi-Fi in respect to both interference and channel access. The combination of these features and th e new spectrum is marketed as Wi-Fi 6E and the combined solution positions the Wi-Fi industry to tackle the challenging wireless factory scenario.

The scope of this thesis is a qualitative study on the performance of Wi-Fi 6E networks evaluating how well such a system can fulfill the requirements of the smart factory.

You will

  • Familiarize yourself with Industry 4.0 scenarios and requirements
  • Perform a survey of Wi-Fi 6 features and assess their relevance for Industry 4.0 use cases
  • Implement selected features in a radio network simulator
  • Perform system simulations and analyze the results
  • Propose innovative improvements to influence the next generation of Wi-Fi.

To be successful in the role you must have

  • One semester left of your Master studies within electrical engineering, computer science, computer engineering, machine learning or similar.
  • Wireless communication knowledge
  • Preferably hands on experience with Monte Carlo simulations
  • Programming skills in Java, Python, Matlab
  • Innovative and creative thinking
  • English written and spoken
