As the telecommunications landscape evolves, Integrated Sensing and Communications (ISAC) is emerging as a transformative concept within the 6G framework.
This innovative approach allows cellular networks to function as both communication channels and environmental sensors, enabling Mobile Network Operators (MNOs) to redefine their roles beyond mere data conduits. According to ABI Research, ISAC presents significant commercial opportunities for MNOs, allowing them to penetrate markets previously untouched by existing technologies.
ABI Research's senior research director Dimitris Mavrakis, emphasises that ISAC offers mobile operators a chance to break free from their legacy of connectivity. By utilising network APIs, MNOs can facilitate location and positioning services across their networks, aiding enterprises in asset tracking and location protection.
This capability is seen as essential for MNOs looking to sustain growth in an increasingly competitive environment. As Mavrakis notes, “ISAC is the first truly innovative concept discussed for cellular networks since 4G introduced mobile broadband.”
In 2025, various vendors and mobile operators are actively conducting live trials to assess the technical and commercial viability of ISAC. Standards organisations like ETSI and 3GPP are also advancing their standardisation efforts. Initial trials in China have shown some commercial interest, particularly in relation to the low-altitude economy, although it remains too early to fully gauge the technology's market potential.
However, the transition to ISAC is not without challenges. A significant hurdle is that fully capable ISAC radios are not backward compatible with existing 5G infrastructure, leading to substantial upgrade costs that could range from $50,000 to $100,000 per cell site.
This financial burden may deter some mobile operators from making the leap at this stage, despite the potential long-term benefits. Nevertheless, as demand grows and economies of scale are realised, it is expected that costs will decrease, opening up further opportunities for ISAC deployment.
Investments in research and development for ISAC are already underway, with vendors filing for relevant patents. While it is still early days, ISAC holds the potential to disrupt traditional market dynamics and foster a new ecosystem within the telecommunications sector. As such, early adopters are urged to evaluate this technology now, as interest and investment in ISAC are on the rise.
