Design for imperfect manufacturing and challenges of making wireless optical system KORUZA

Luka Mustafa

Shuttleworth Foundation Fellow - Institute IRNAS Rače in Slovenia

Abstract

Complicated and precise systems can be designed more smartly with imperfect tools and machines, demonstrated by the example of KORUZA, a low-cost wireless optical and open source open-hardware system for gigabit 100m wireless communication in urban areas. Motivation for developing this project comes from Wi-Fi, which is the most popular choice for creating low-cost networks these days. However, a large number of such networks fail to co-exist in urban environments due to RF spectrum congestion. KORUZA solves this problem by using a highly collimated optical beam for bi-directional communication. In this talk I will discuss the use of 3D printing for development of precise optical setup with imperfect parts, how to design a system using and re-purposing mass-produced off-the-shelf components, discuss impacts of setting up a global distributed experiment World Wide Koruza experiment and observing the developed product in real-life. I will also demonstrate the latest KORUZA 1.0 prototype now suitable to make wireless optical gigabit links between buildings.

Bio

Luka Mustafa is a Shuttleworth Foundation Fellow and working full-time on developing the wireless optical system, KORUZA, at Institute IRNAS Rače in Slovenia, which he founded in 2014. He is also working on his PhD at University College London. For the past year he has led a keen young team at IRNAS to develop open hardware manufacturing solutions ranging from precise 3D printing of plastics and other more unusual materials to large-scale CNC and plasma cutters for heavier metalwork, innovating on the use of optical fibres for these applications. He promotes and deploys open wireless networks with the "wlan slovenia" project, manages national and international wireless backbones and contributes to several open-hardware and electronics projects worldwide. He has wide experience interning on projects from sound-systems to particle accelerator control systems.
