DARPA’s Communicating with Computers (CwC) developing technology to facilitate human-like communication between warfighters and their unamnned vehicles

The lifelong human imperative to communicate is so strong that people talk not only to other people but also to their pets, their plants and their computers. Straightforward as that may sound, communication involves several coordinated processes. The speaker puts ideas into words, the listener extracts ideas from words and, importantly, …

DARPA exploring the convergence of biology and electromagnetics for military communications and sensing

Radio frequency waves (RF) are electromagnetic waves between the frequencies of 3 kilohertz to 300 gigahertz, used in radio, cellphones, wi-fi, radar, GPS, and many other systems. While humans have used RF technology to communicate for over 100 years, no living organism has ever been observed using RF to communicate …

DARPA’s HERMES developed next generation extremely wideband, jam-resistant radios, based on RF photonics technology

Access to spectrum is also critical for future swarm of UAVs, In a vision shared by innovators, entrepreneurs, and planners in both defense and civilian contexts, the skies of the future will be busy with unmanned aerial vehicles (UAVs). Unseen but central to the realization of this vision is wireless communication …

DARPA CommEx developed cognitive radio technologies that maintain communications even under severe jamming environment

Russia, has displayed jamming and spoofing capabilities in the ongoing conflicts in Ukraine and Syria in the last several years. The use of Russian technology in these conflicts demonstrated that Russia retains advanced electronic warfare capabilities.   Russia has deployed Electronic Intelligence (ELINT) and SIGINT aircraft, such as the Il-20, …

DARPA’s AMEBA developing transmitters that could communicate through walls, undersea and underground environment

Modern day radio transmitters and receivers, the devices that uses electromagnetic wave signals to communicate through cellphones, radios and television, seem to be present everywhere.  The propagation of these electromagnetic waves has some limitation too,   Key among these is that radio frequency signals hit veritable and literal walls when they …

DARPA IAMANET developed scalable and secure Mobile Ad Hoc Networks (MANETS) to support an entire battalion

The modern battlespace is an irregular, against a tech-enabled enemy, and within urban environments and/or complex terrain. Traditional communications infrastructure like cell phone towers are centralized therefore vulnerable to single point failures such as physical damage to their central server, or compromised by a cyber-attack. During disasters like earthquakes, tsunamis …
