DARPA has awarded a contract for the third and final phase of its Advanced RF Mapping program, known as RadioMap, which seeks to provide real-time awareness of radio spectrum use across frequency, geography and time. Akin to smartphone maps that show color-coded current traffic conditions, RadioMap is developing technology that visually overlays spectrum information on a map enabling rapid frequency deconfliction and maximizing use of available spectrum for communications and intelligence, surveillance and reconnaissance (ISR) systems.
At the end of 2013, the United Nations General Assembly designated 2015 as the International Year of Light and Light-based Technologies (IYL 2015). And what could be more worthy of celebration than light?
Competition for scarce electromagnetic (EM) spectrum is increasing, driven by a growing military and civilian demand for connected devices. As the spectrum becomes more congested, the Department of Defense (DoD) will need better tools for managing the EM environment and for avoiding interference from competing signals. One recent DARPA-funded advance, an exceptionally high-speed analog-to-digital converter (ADC), represents a major step forward. The ADC could help ensure the uninterrupted operation of spectrum-dependent military capabilities, including communications and radar, in contested EM environments.
DARPA today announced the newest of its Grand Challenges, one designed to ensure that the exponentially growing number of military and civilian wireless devices will have full access to the increasingly crowded electromagnetic spectrum. The agency’s Spectrum Collaboration Challenge (SC2) will reward teams for developing smart systems that collaboratively, rather than competitively, adapt in real time to today’s fast-changing, congested spectrum environment—redefining the conventional spectrum management roles of humans and machines in order to maximize the flow of radio frequency (RF) signals.
Since the advent of the integrated circuit in 1958, the same year the Advanced Research Projects Agency was established, engineers have been jamming ever more microelectronic integration into ever less chip real estate. Now it has become routine to pack billions of transistors onto chips the size of fingernails.
