Ericsson Revolutionizes Mobile Networks with Drone Detection Solutions

In an era where drone technology is rapidly advancing, the issues surrounding low-flying, fast-moving drones have become increasingly significant. Ericsson, a frontrunner in the telecommunications sector, has now made strides in addressing these challenges by unveiling its Integrated Sensing and Communication (ISAC) system. This innovative technology allows mobile networks to not only connect users but also to detect and track drones effectively, thus enhancing safety in various critical areas.

The ISAC system introduces a necessary evolution in mobile network capabilities, bridging the current gap that exists in detecting drones across expansive, low-altitude airspace. Due to their compact size and unpredictable flight patterns, small drones pose a unique challenge for national security and the protection of critical infrastructure. They have become tools for unlawful activities, including surveillance and sabotage, necessitating robust detection solutions. What sets Ericsson’s ISAC apart is its ability to rely on existing mobile infrastructure to detect these elusive objects, making it a cost-effective and immediate solution.

How the ISAC System Works

The Ericsson ISAC system utilizes advanced technologies, including AI and edge computing, paired with the existing 5G mobile network infrastructure. This system operates on a multi-static model, whereby sensing signals are transmitted and received across various mobile network sites. Consequently, this geographical spread allows for a comprehensive view of objects from multiple angles, significantly improving detection accuracy and reliability.

The capacity of the ISAC to monitor low-flying drones is primarily achieved through the analysis of radio signals. As the signals bounce off surrounding objects, the system interprets these reflections to identify and track the drones in real-time. In practical trials, this technology has demonstrated an exceptional ability to detect micro drones over distances up to several kilometers, providing precise 3D positioning.

In collaboration with notable partners, including AT&T in the USA and Erillisverkot in Finland, practical demonstrations have successfully illustrated how the ISAC technology can integrate seamlessly into existing networks. For instance, in Arlington, Texas, AT&T and Ericsson utilized the sensing dashboards in a live test to track multiple drones, showcasing how mobile networks can support public safety initiatives and critical infrastructures.

Benefits and Applications

The potential applications of this innovative detection technology are vast. In defense and public safety sectors, the ISAC can enhance airspace monitoring, allowing for better oversight of borders and strategic assets. Critical infrastructure sectors, such as ports and power plants, will benefit from reinforced protection against unauthorized drone activity. Furthermore, industries connected to transport and logistics can utilize this technology to manage airspace in urban environments and ensure safer operations.

The impact of Ericsson's ISAC system extends beyond commercial applications; it also paves the way for a low-altitude economy. As more cities embrace drone technology for deliveries, surveillance, and other applications, the need for efficient drone traffic management becomes pivotal. The ISAC system is designed to meet these emerging demands, facilitating collaborative urban airspace oversight and smart city planning initiatives.

Ericsson’s initiative reinforces its commitment to leveraging its extensive network infrastructure to advance public safety and security. Freddie Södergren, the Global Head of Mission Critical Networks and Defense, emphasized that traditional sensors alone cannot adequately cover the extensive areas required for effective drone detection. The ISAC system provides a logical and efficient enhancement by integrating existing network assets with innovative detection capabilities.

As the landscape of aerial surveillance and usability evolves, Ericsson’s ISAC technology stands at the forefront of a new paradigm in mobile network potential. With plans for a gradual rollout starting in 2027, including small-scale trials, the aim is to eventually implement extensive sensing capabilities by 2028. Through this timely advancement, Ericsson not only addresses current safety concerns but also lays groundwork for the future of drone management and urban safety solutions.
