The nature of complex combat operations must now include adversaries that have peer-level capabilities, such as the ability to locate friendly troops by their transmissions and jam their radios so they can’t call for help, setting them up for attack. However, critical to all combat scenarios, regardless of adversary capability levels, is the need to command, control, communicate and exchange information with dispersed assets. Tactical communication systems must demonstrate the ability for rapid shutdown, relocation with maneuvering forces, and reconstitution with little action required by the operators in a stressful environment, while maintaining low probability of detection and low probability of interception. Clearly a new technology solution is required that eliminates the vulnerabilities and bandwidth limitations of RF-based tactical communication systems. Free Space Optical Communication (FSOC) systems virtually eliminate the RF footprint-related vulnerabilities by using lasers as the information "carrier". Tau Technologies and OptiPulse, Inc, are teaming to develop a breakthrough new solution using OptiPulse's revolutionary Vertical Cavity Surface Emitting Laser (VCSEL) array technology. Our "Adaptive FSO Mesh Network" system provides a power-efficient, high bandwidth, high data rate tactical communication capability that is undetectable. Our concept can adapt to, and maintain data links in, battlefield environments having challenging atmospheric conditions.

The primary objective is to develop, characterize, and deliver for Army evaluation a 10 GbE compatible optical mesh network that supports full duplex communications over distances of up to 2 km per link using packable hardware. Each of the four nodes will include two FSOC 10 GbE transceivers that can be remotely and independently aimed over azimuthal angles of 360 degrees and tilted +30 to -90 degrees from horizontal. Mounting apparatus will elevate each pair of line-of-sight transceivers to heights between 11’ and 14’ above ground to clear tents, vehicles, vegetation and other obstacles. Supporting networking equipment will allow rerouting of network traffic, as already demonstrated in Phase I, via other nodes in the network should an operating link become blocked or disabled. Network operations monitoring software running in a Windows environment on Army laptop computers will use a graphical user interface (GUI) to display network configuration and status along with performance metrics and signal alarms for each link, obtained from diagnostic capabilities built into the transceivers. For example, packet error rates will be used to infer bit error rates (BERs), which will be < 10-6 or lower. The Army’s field evaluation, including warfighter strike-move-setup, will be supported by providing training materials and access to a subject matter expert.
