Ericsson to Use Mobile Networks for Drone Surveillance

A New Frontier in Airspace Security

Ericsson has unveiled a technology that transforms mobile networks into tools for detecting and monitoring drones. The Integrated Sensing and Communication (ISAC) system leverages existing telecommunications infrastructure to track airborne objects using radio signals. This approach is particularly effective at identifying low-altitude drones, where traditional radar systems often struggle.

The system functions by analysing radio signals that bounce off a drone. By aggregating data from multiple mobile towers, the system can precisely determine an object's location and flight trajectory. According to Ericsson, this solution avoids the need to build separate, costly surveillance systems, as it is designed to integrate directly into existing infrastructure.

Technical Details and Testing

Implementing this system does not mean every existing tower will automatically begin tracking drones. The technology requires specialised radio equipment, including Massive MIMO (multiple-input multiple-output) antennas, which are capable of processing complex radio signals.

The technology has already been successfully tested by AT&T in Arlington, Texas, and by Erillisverkot in Finland. In both instances, the system successfully identified drones and tracked their movements with precision. Ericsson plans to initiate limited commercial trials in 2027, with full-scale availability expected by 2028.

Why It Matters

Unauthorised drone flights pose a significant threat to airports, military installations, and private properties. Recently, there have been numerous instances where drones have disrupted airport operations. While traditional radar often fails to cover low altitudes, mobile towers operate at precisely these levels, making them ideal for surveillance.

Experts suggest that future 6G technology will further improve the system's accuracy by enabling the use of wider channels. However, Ericsson emphasises that this system is intended to complement, rather than replace, existing surveillance mechanisms. The company continues to evaluate how the technology will perform in challenging environments, such as dense urban areas or complex terrain.

For countries like Georgia, where mobile network infrastructure is developing rapidly, such technologies could become an essential tool for protecting critical infrastructure, simplifying the adoption of modern security standards.
