Swisscom and Ericsson: A Performance Partnership driving network leadership
Swisscom has set the benchmark for mobile network performance in Switzerland – consistently ranking #1 across all major evaluations. Behind this success is a long-standing partnership with Ericsson, focused on delivering innovation, automation, and operational excellence that empowers Swisscom to lead with confidence.
Highlights
Sustained leadership
Swisscom has won all major mobile network benchmarks in Switzerland since 2017, despite fierce competition. This consistent performance reflects a commitment to quality, innovation, and outstanding customer experience. Ericsson’s technology and strategic collaboration have been key to this success, enabling Swisscom to stay ahead in a competitive market.
“Our long-standing partnership with Ericsson has been a cornerstone of Swisscom’s network leadership. Together, we’ve not only reclaimed our top position but also made a strong contribution to excellence in mobile connectivity.”
- Mark Düsener, CTIO at Swisscom
Innovation through collaboration
With a 100% Ericsson Radio Access Network (RAN), Packet Core, Unified Data Management (UDM) and IP Multimedia Service (IMS), an Ericsson telecom cloud infrastructure, and a strong joint R&D foundation in all these domains, Swisscom has deployed some of the most advanced network technologies available.
From Carrier Aggregation, Advanced Antenna Systems with Massive MIMO and Cognitive Network Solutions AI-based automations, to advanced Transmission Control Protocol (TCP) optimizations, these innovations have delivered measurable gains in throughput, latency, and jitter, ensuring that Swisscom’s 4G LTE and 5G NR networks remain best-in-class.
Over the years, Swisscom has also invested heavily in performance observability and advanced analytics, using, for example, Ericsson Expert Analytics software, which has enabled Swisscom to implement targeted performance improvements. In the Packet Core and UDM space, Swisscom and Ericsson are jointly charting the way toward a new cloud-native future with the introduction of the Ericsson cloud-native Dual Mode Core. This solution features advanced automation, delivering order-of-magnitude improvements in operational efficiency compared to their virtual network function deployment.
Efficiency at scale
Swisscom now operates a network that is three times larger and handles four times the traffic it did in 2017, while simultaneously decreasing operational expenditure.
This has been made possible through automation, AI/ML-driven optimization, and the continuous introduction of new software releases with enhanced functionality.
For a long time, Swisscom has been testing new RAN software every two weeks and deploying the latest release nationwide several times a year. More recently, Swisscom has developed automation for its new dual-mode core network, enabling the deployment and end-to-end integration of multiple network functions into the production network within days rather than the weeks or months it previously required.
Looking to the future, Swisscom is aiming to raise the bar, enabling frequent software releases across its entire mobile network, facilitated by automation. It is a clear example of how smart engineering can scale sustainably.
“Working with Ericsson, we’ve built a network that’s not just fast – it’s intelligent. By integrating AI-driven automation, cloud-native architectures, and real-time analytics, we’ve laid a solid foundation for fast adaptation and scalability.”
