DARPA developing milimmter wave wireless communications to connect dismounted warfighters using UAVs and provide 100 Gb/s RF Backbone (100G)using High-altitude, long-endurance platforms.

Modern expeditionary military missions generate and exchange massive amounts of data that are used to produce situational awareness and guide decision-making. Much of the data must travel long distances along backbone communications networks composed of high-capacity links that connect command centers.   Fiber optic cables provide the core backbone for …

Military exploring LiFi technology for secure high data rate communications for facilities, vehicles and submarines

The Li-Fi is a wireless communication system in which light is used as a carrier signal instead of traditional radio frequency as in Wi-Fi.  Li-Fi is a technology that utilizes a light emitting diode to transmit data wirelessly. LiFi works by switching LEDs on and off within nanoseconds to communicate …

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 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 …
