Ericsson has introduced a 5G-based drone detection system to strengthen airspace security across cities and critical infrastructure. Announced on November 2, 2026, the Ericsson ISAC System uses existing mobile networks to detect unauthorized drones.
The technology targets defense agencies, public safety authorities and infrastructure operators. Selected commercial pilots will begin in 2027, followed by wider deployments from 2028.
The Integrated Sensing and Communication (ISAC) System transforms existing 5G infrastructure into a distributed drone tracking network. It combines 5G radios, artificial intelligence, edge computing and signal processing to identify moving objects.
The technology can also track drones that never connect to mobile networks. This approach could expand surveillance coverage without requiring entirely separate detection infrastructure.
Unlike conventional detection methods, Ericsson's system analyzes radio signals reflected by objects moving through monitored areas. Multiple mobile network sites capture these reflections from different angles to improve tracking accuracy. The system also provides three-dimensional positioning and maintains object tracking across coverage areas.
Ericsson reported successful tests involving micro drones at kilometer-scale distances under validated conditions. However, detection performance depends on drone characteristics, flight patterns, terrain and surrounding environmental conditions. The company also emphasized that its technology complements existing radar and other detection systems.
The company has already demonstrated the technology alongside telecom operators and technology partners. A trial with AT&T in Arlington, Texas, successfully detected and tracked multiple drones.
Another demonstration with Finland's Erillisverkot showcased coordinated detection through multiple 5G network sites. In Poland, Ericsson collaborated with Asseco and Play to combine network sensing with acoustic detection.
Freddie Södergren, Ericsson's Global Head of Mission Critical Networks and Defense, highlighted the technology's wider security potential. He said, "Low-flying drones create a detection coverage gap that no single sensor can effectively address."
The company sees applications across border monitoring, coastline surveillance, ports and power plants. Transport networks, industrial facilities and urban drone traffic management also represent potential deployment areas.
Ericsson plans to introduce sensing-only commercial pilots with selected customers during 2027. Broader deployments will follow from 2028 as the technology develops towards 6G. The company also plans to integrate communications capabilities into future versions of the system.
