6G Integrated Sensing and Communications Poised to Reshape Mobile Networks

Integrated Sensing and Communications (ISAC), a core concept for 6G, enables cellular networks to function as radars, sensing their environment while transmitting data, according to ABI Research’s *Integrated Sensing and Communications: Market Developments & Use Case Analysis* report. This technology presents mobile network operators (MNOs) with opportunities to enter new markets not currently served by other technologies or companies.

ISAC allows MNOs to move beyond traditional connectivity roles, potentially acting as brokers for location and positioning services across their network footprint to help enterprises track assets and secure locations. However, deploying ISAC faces significant technical challenges, including the lack of backward compatibility with existing 5G infrastructure. Upgrading to ISAC-capable radios could cost $50,000 to $100,000 per cell site, a factor that may deter MNOs given the market’s early stage.

In 2025, vendors and MNOs are conducting live commercial trials to evaluate ISAC’s technical and commercial viability, with initial trials in China showing interest driven by the low-altitude economy. Standardization efforts by ETSI, 3GPP, and other industry bodies are ongoing. Vendors are investing in research and development and filing patents, indicating early-stage market development.
