The Department of Defense (DOD) is seeking proposals for the Non-RF Transceiver Alternative Communicator (NRF-TAC) through its SBIR program. The U.S. Army is interested in developing a small, energy-efficient transceiver that can wirelessly communicate between two points without using traditional radio frequency (RF) transport. The NRF-TAC device should be capable of transmitting and receiving signals up to 300 meters using non-standard means such as magnetic, acoustic, or infrared communication. The goal is to create a communication method that is difficult to detect and report in covert activities, enabling new mission deployment possibilities for remote sensor operation and control. The NRF-TAC should be self-contained, easily concealable, field programmable, and able to operate for at least 800 hours without intervention. The SBIR effort involves designing and building an innovative NRF-TAC prototype for realistic field application. Phase I involves creating a design with a documented rationale, while Phase II focuses on developing and testing a prototype. The potential applications of NRF sensor technology include home security, automotive crash sensing, additive manufacturing, and IoT. The solicitation is open until March 31, 2025.
