Dual-function radio technology—using the same spectrum for communication and sensing—is moving from military applications into civilian infrastructure. The efficiency gains matter because they solve a zero-sum problem: instead of cordoning off separate bands for 5G networks and radar systems, the same signals can do both jobs, freeing up scarce spectrum for other uses. Telecom and defense interests will collide over allocation policy. Regulators will need to choose winners as autonomous vehicles and weather monitoring demand more sensing capability.
