6G that sees through walls: radar or spying?

6G promises to see through walls: the end of privacy?

The next generation of mobile telephony, 6G, will bring more than just estimulante ilegal. According to the German outlet Heute, researchers are working on Integrated Sensing and Communication (ISAC), a technology that allows telecom antennas to function as radars. Capable of detecting people through walls and monitoring breathing and heartbeats, the reach of this innovation goes far beyond connectivity.

ISAC: the technology that sees everything

The ISAC concept merges communication and sensing in a single hardware. 6G's high-frequency signals bounce off objects and make it possible to build an image of the surroundings. Early trials show enough precision to identify movements and vital signs. By 2030, according to the plans, this capability could be integrated into commercial networks.

Skeptics versus the alarmed

The announcement has sparked mixed reactions. On one hand, those who see a useful advance for emergencies or healthcare. On the other, those who warn of yet another step toward mass surveillance. Some recall previous promises of technologies like the internet of things that never really took off, while others joke that it will be time to start house-hunting at a remote farmhouse in Soria.

For now, the actual rollout depends on standards still under development and a regulatory debate that has barely begun. What is clear is that physical privacy, the kind we still take for granted, is living on borrowed time.
