The Department of Defense (DOD) is seeking proposals for the development of a small energy-efficient self-contained transceiver capable of wireless communication without using traditional radio frequency (RF) transport. The goal is to utilize a non-standard means of signal communication, such as magnetic, acoustic, or infrared, that is difficult to detect and report in covert activities. The transceiver should be highly resistant to interference, detection, and exploitation, and be self-contained, man-portable, easily concealable, and field programmable. The project duration is divided into two phases: Phase I involves creating a plausible design and rationale supporting the solution, while Phase II focuses on developing and testing a prototype that demonstrates the desired capabilities. The project aligns with the Army's smart sensing initiatives and aims to provide an innovative alternate means of low probability of detection (LPD) and low probability of interception (LPI) communications. The solicitation is open until March 31, 2025. For more information, visit the solicitation link.
