Secure EMI-free Light Communication System

To address the Navy need for a secure and reliable wireless network without electromagnetic interference (EMI), Intellisense Systems, Inc. (ISI) proposes to develop a new Secure EMI-free Light Communication (SELICOM) system. It is based on a novel design of the Light Fidelity (Li-Fi) attocell that utilizes results of the latest research in light modulation and state-of-the-art development of solid-state devices. Specifically, the innovation in using multi-wavelength LEDs integrated in an optimized transceiver design, orthogonal frequency division multiplexing modulation, and enhanced security features will enable the wireless network in the undersea platform to deliver high-bandwidth communication with increased security, improved reliability, and without interference. As a result, this technology provides >1.5 Gbps data bandwidth per attocell, eliminates EMI, and enables creation of a scalable wireless network that offers multiple levels of security through geofencing, restricted use of wavelengths, and line-of-sight connections. In Phase I, ISI developed a concept of a Li-Fi communications system and demonstrate its feasibility. In Phase II, ISI will develop and deliver a system prototype capable of transmitting data between a Li-Fi attocell and up to eight network nodes with performance superior to 1G Ethernet cables and Wi-Fi links.
