Drone warfare is reshaping telecom priorities faster than many expected. A capability once seen as native to 6G is now moving into late-stage 5G networks.
The technology is integrated sensing and communications, or ISAC. It allows mobile networks to sense objects, not just carry data. In simple terms, network radios can act like distributed radar points.
The urgency comes from changing battlefield economics. Low-cost drones now threaten military sites, cities, and key assets. Traditional radar and missiles remain powerful, but they are expensive. They also struggle with low-flying drones beyond line of sight.
Ericsson says existing mobile sites can help close that gap. The company has been asked to accelerate sensing features planned for 6G. “There has been a big push to get something to market quicker,” says Christopher Ling, chief executive at Ericsson Federal.
The current 5G approach is not fully integrated with communications yet. Ling described it as a standalone capability. Still, it shows how operators could reuse radios, towers, and spectrum for detection.
Ericsson recently demonstrated the idea with AT&T near AT&T Stadium in Texas. The test used several radios in a multi-static setup. One radio sent a signal, while others listened for reflections. This helped locate and track drones at roughly 300 to 400 feet.
That matters because basic detection is not enough. Operators and security teams need position, speed, and direction. “Multi-static gives much higher accuracy, and allows you to track. Everyone says ISAC is great, but there’s a big difference between knowing something’s out there, and being able to track it – which takes this more sophisticated multi-static approach.”
The system can also help identify drone types. It reads tiny signal changes from moving propellers. Ling compared the idea to hearing an ambulance change pitch as it passes. That sound shift reveals speed and movement.
For telecom operators, the opportunity extends beyond defense. Stadiums, ports, airports, factories, and power sites need drone awareness. Future delivery networks may also need low-altitude traffic control. That could support drone deliveries from retailers and restaurants.
However, the path is not simple. Regulators must approve testing and radio changes. The FCC process already complicated earlier goals. Vendors also need more processing power for busy drone environments.
Private 5G networks will likely come first. Stadiums and military locations can control deployment more easily. National coverage would require multiple operators and vendors working together.
Ling expects commercial products to arrive soon. “Probably, some time next year. We’re working on a commercial product now.” A fuller 6G version will follow later, as standards mature.
The wider message is clear. Mobile networks may soon do more than connect phones and sensors. They may also watch the skies. For operators, ISAC could create fresh service revenue. For governments, it could make drone defense more affordable.
