Long-range Communications without Large, Power-Hungry Antennas

DARPA News  June 9, 2020
To break the dependence on big antennas and amplifiers for establishing long-range tactical communications for U.S. troops in remote locations, DARPA recently announced the Resilient Networked Distributed Mosaic Communications (RN DMC) program which aims to provide long-range communications through “mosaic” antennas composed of spatially distributed low SWaP-C transceiver elements or “tiles.” This approach replaces high-powered amplifiers and large directional antennas with mosaics of dispersed tile transceivers. Transmit power is distributed among the tiles, and gain is achieved through signal processing rather than by a physical antenna aperture to concentrate energy. The antenna mosaic concept could prove more robust against failure or attack since tiles are distributed across air, ground, and sea assets and lower the cost….read more. BAA  Proposers Day
