DARPA is developing an unjammable communications chip
Electronic warfare (EW) techniques -- from killing missiles with microwaves to downing drones with radio interference -- have become an integral part of modern wars. This issue is exasperated by the fact that both sides in a conflict must also compete for the finite spread of interference-free wireless spectrum with which they operate their multitude of wireless devices. To maintain American fighting superiority over the likes of China and Russia, both of whom are considered "near peers" in terms of EW combat capabilities, DARPA has developed an ultrafast chip to convert analog wireless signals into digital ones in record time.
