Expanding applications of networks as sensors Wireless networks acting as sensors and providing a more agile alternative to radar is gaining traction. The concept of networks that sense is not restricted to wireless sensing. It has been known for over half a century that optical fibers can be used not only for communication but also for sensing. Both economic powers are looking to gain a first-mover advantage as sensing technologies take on a new dimension. “We are at a tipping point for sensing technologies,” says Vetter.
