The Koruza driver is an additional board to Koruza router. Its main task is to handle the real-time parts of Koruza system, like stepper motors for the laser beam positioning, infrared communication between two Koruza units, encoders for stepper motors, etc. The Koruza driver consists of the two separate PCB boards. First is the driver board. It is the main...

Optical wireless system KORUZA operates by directing a collimated beam of light towards another unit to establish communication. To be able to precisely aim a beam of light with a millimeter precision when shining at a distant unit at 150 m away, one requires two key components; a precise motor drive (see blog about it) for mechanical displacement of a...

KORUZA wireless optical system enables 1Gbps or 10Gbps communication with a collimated beam of light between two buildings. To interface and power the units, networking ports are required, we looked at a number of practices from various vendors. For throughputs up to 1Gbps the standard interface is wired RJ-45 ethernet. WiFi routers and other networking devices are often powered through...

For Koruza Pro we wanted to find a solution for the sealing, such that the units would be easy to assemble, use small part count and be cheap for manufacturing. Until the version 2.3.1 we used an independent internal supporting structure for the motorized alignment system and PCB supports, like shown in the picture 1. A rectangular, 2 mm thick...

We are interested in how our wireless optical system KORUZA operates in various environmental conditions and to better understand the signal loss mechanisms, we are conducting scientific experiments in our domain. Free Space Optical systems use visible or near IR wavelengths to wirelessly transmit data and are thus susceptible to ambient and weather influences that may cause temporal decrease in...

Our next generation device KORUZA Pro will enable a versatile construction of last-mile networks to people’s homes and thus deliver them a faster internet service. To best cover all the possible installation scenarios and provide a user friendly installation process, we are exploring and innovating on the mounting system. The mounting system needed to be smaller than the mount on...

Wireless optical system KORUZA and other FSO systems require that the units are pointed at each-other to be able to receive the collimated beam of light that transfers the data between them. Typically an infrared and invisible to the human eye beam is used and thus we can not simply see where one unit is pointing. To solve this, generally...

The challenge of demonstrating wireless optical communication with an invisible optical beam as with our KORUZA system is in showing the transmission of data with light, since it is difficult to have a direct interaction between people and data. To be able to demonstrate at least in part what is going on, we have resorted to using LED diodes and...
