Why it matters

Masthead tests whether drone detection can be sold as national infrastructure on existing mobile networks instead of as standalone sensors. For Sensofusion, Elisa offers distribution a 111-person company cannot build alone. For Elisa, it creates a security service for government and infrastructure customers. The unanswered questions are technical and commercial: which sensors will be deployed, what coverage they deliver, who buys the service, and who controls the tracking data.
