Networking architecture for UAV swarms using short-range single-payload laser communication

This paper presents a new framework for long range Free Space Optical communication (FSO). Motivated by the ever-growing demand for communication in 5G networks, the suggested framework tackles the natural FSO link drawbacks, commonly: complicated installation, limited range, size and pricing. The new FSO concept assumes a "best effort" model. It uses a new control and aiming mechanism for the Tx laser beam based on COTS components. This methodology is mostly suitable for urban FSO links but might also be applicable for both short range (IoT) and long range (satellite) communication. Based on simulations and preliminary field results we expect that such FSO links will be widely used in "best-effort" 5G applications allowing an affordable alternative to fiber optics and standard FSO systems.

Research and development of laser communication in Israel encompasses many different areas including inter-satellite communication, terrestrial communication and indoor communication. The R&D activity is mainly being carried out in two sectors: academia and industry. Additionally there is some activity in start-up companies. In this paper, I survey several areas of R&D activity to which Israel has contributed. 1) Broadband Laser Inter-satellite Link (BLISL). This is a joint Israeli-German five-year applied research project supported by the DIP foundation. Its objective is to develop technologies and know-how for broadband optical inter-satellite communication terminals for applications on small satellites in LEO/MEO constellations. 2) Urban optical wireless systems. This area has received much attention in academia. The main task is to quantify atmospheric effects on system performance and to apply this information in industry. 3) Short range communication for indoor applications. The main aim here is to develop adaptive techniques 4) Agile laser scanning/steering. This technology is essential for the next generation of optical wireless systems. 5) Atmospheric probing. We discuss a new concept for atmospheric probing known as firefly clustering.
