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

Ericsson Research

Ericsson Research is the central research organization within the Ericsson group. We are about 600 researchers in many countries with the central site in Kista, Stockholm. Our mission is to provide Ericsson with system concepts, technology, and methodology, to secure long-term competitive product provisioning. World-class innovation is achieved through cooperation within Ericsson and with partners, customers, universities, and research institutes.

Industrial automation and distributed AI are important pillars of 6G. Industrial automation, including factory automation, is considered the main driver for time-sensitive networks (TSN). One of the main requirements for industrial automation is high reliability (e.g., 10 years without application fail down), availability (e.g., 99.9999%), and low latency (below some tens of milliseconds). We call such extreme quality of service as ultra-reliable low latency communication (URLLC). Enabling URLLC may require a huge slice of network resources. However, there are growing interests for distributed AI, mainly due to its privacy and security promises. Distributed AI services, especially in the training phase, often require running communication-heavy algorithms, which can be a bottleneck for serving URLLC traffic. Despite the importance of these two services, we do not know their mutual impacts. Such knowledge would help better design the network slicing to efficiently run two services without over-utilizing network resources. This thesis aims at understanding this fundamental interplay. Such knowledge is essential to develop an efficient distributed AI over mobile networks, which can be integrated into network orchestrator and network slicing mechanisms.


The aim of this thesis is to use our network simulator to analyze the interplay between URLLC traffic and distributed training service for multiple networking settings and exploit the insights to develop URLLC-friendly distributed training algorithms.

You will

  • Study our network simulator
  • Investigate KPIs to evaluate performance of URLLC and distributed training services;
  • Run an example scenario of factory network running both services and produce data out of the simulator;
  • Measure the performance degradation of URLLC in the presence of distributed AI services. Here we consider various AI settings which includes: 1) model size, 2) distributed training algorithm and 3) number of nodes and background traffic;
  • Develop an algorithm that optimizes system configuration including AI and network configs; and
  • Report to the Research Manager.

To be successful in the role you must have

  • Basics of ML
  • Wireless networks or equivalent (optional).
  • Good background in Python (background in Java is a plus)
  • Course requirements must have been fulfilled for the degree project
  • Good spoken and written English
  • Ability to perform studies and reports
  • Ability to do innovation
  • The candidate should be self-driven and able to initiate action
  • Ability to work independently, as well as collaborating in teams
  • Good presentation and communication skills
