Abstract: To address the Navy need for a secure and reliable wireless network without electromagnetic interference (EMI), Intellisense Systems, Inc. (ISS) 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 up to 3.4 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, ISS will develop a concept of a Li-Fi communications system, demonstrate its feasibility by exceeding 1 GbE cable speed, and prepare a plan for Phase II prototype development. In Phase II, ISS plans to develop and deliver a system prototype capable of transmitting data between a Li-Fi attocell and computers with performance superior to Wi-Fi.
Benefits: The SELICOM technology with its increased speed, improved reliability, and heightened security will provide an alternative to Wi-Fi wireless networks in military and commercial applications. Specifically, locations that would normally not allow Wi-Fi, such as medical facilities, airplanes, and military platforms sensitive to EMI, will be the primary beneficiaries. As the Li-Fi technology matures, its dual use of LED lights for illumination and wireless data transmission will find a rapid adoption for indoor wireless networks, replacing Wi-Fi at home, in the office, and in manufacturing facilities and outdoors by providing wireless access in the streets and industrial and military facilities.
