KORUZA, the open-source open-hardware wireless communication system


KORUZA, the open-source open-hardware wireless communication system by Luka Mustafa – Musti

KORUZA is an innovative open-source open-hardware wireless communication system, employing a new low-cost approach to designing free-space optical network systems, enabling building-to-building connectivity with a highly collimated light beam at a capacity of 1 Gbps (1000 Mbps) at distances up to 100 m.

It is designed to be suitable for home as well as professional users, enabling organic bottom-up growth of networks by eliminating the need for wired fiber connections and associated high installation costs. The simplicity of use, low-cost and compact size allow the system to be deployed in any network.

  1. Uses a laser… If they went with LED-based like RONJA (ronja.twibright.com) they’d probably be able to go farther. Lasers have the problem that they’re coherent so thermal pockets can cause them to self-interfere (think speckle paterns).

    1. It is true that coherent laser light has a speckle problem. It is also true that it is difficult to find a high-power LED that you can modulate at 1 GHz :-)

  2. Flimsy 3D printed stuff for precision optics ? not a good idea.
    What if a bird flies through ?
    What happens when the building shakes ?
    What happens on athmospheric disturbances ?

    it seems they send the laser on a small diameter beam, also not ideal.

  3. Good idea for test platform (I’d like to have a couple), but not for everyday use… And, I think, device should have the opportunity to mount on a tripod.

  4. What I really want to know is what he’s using for his laser module. I can’t find anything in the wiki or sources about who makes it or components used to create it.

  5. In college they had a similar home-brew optical link between the enginering center’s computer room and the main data center. It worked great except when it snowed, when the engineering center’s terminals and card-reader/printer became useless.
