A Stockholm repair workshop became global mobile infrastructure: Ericsson’s 150-year story

Lars Magnus Ericsson founded a telegraph-equipment repair workshop in Stockholm in 1876.

The business soon began manufacturing telephones and switching equipment as fixed-line communications spread across Europe.

That starting point is useful context for understanding the modern Ericsson. The company did not arrive at its current position in one jump; it accumulated technology, customers and operating knowledge through a series of distinct transitions.

Telephone networks turned repair work into manufacturing

Ericsson expanded from repairing imported equipment to producing telephones and exchanges, then built international operations as national networks grew.

The AI era increased the value of capabilities Ericsson had already been developing. Compute, data, networking, software or infrastructure that once served narrower workloads became relevant to much larger AI systems.

Digital switching prepared the company for cellular systems

Decades of switching and radio engineering positioned Ericsson to become a major supplier of mobile-network infrastructure as cellular standards emerged.

Mobile technology rewarded companies that could scale rapidly while adapting to new standards and device requirements. For Ericsson, the milestone widened the role it could play as connectivity became a default feature of everyday computing.

GSM made Ericsson one of the defining companies of the mobile era

Ericsson became a major supplier of GSM infrastructure during the 1990s and also operated a large mobile-phone business.

Mobile technology rewarded companies that could scale rapidly while adapting to new standards and device requirements. For Ericsson, the milestone widened the role it could play as connectivity became a default feature of everyday computing.

The Sony Ericsson venture moved handsets out of the core

Ericsson combined its handset operations with Sony in 2001. Sony later bought Ericsson’s stake, leaving Ericsson increasingly focused on networks, services and telecommunications software.

The transaction mattered because it changed the shape of Ericsson rather than simply adding revenue. It brought additional technology, customers, geographic reach or operating capability into the group and influenced the next stage of its strategy.

The repair workshop became the plumbing of mobile connectivity

As of 18 September 2026, ericsson is now one of the world’s largest suppliers of mobile-network equipment and software, competing across 5G and future network architectures. Its history is a direct line from telephone infrastructure to increasingly software-defined radio networks.

For readers following the brand today, the history explains why newer announcements often connect back to technology or business decisions made much earlier.
