Kulankhulana wopanda zingwe (Owc) ndi njira yolumikizirana kowoneka kuti signation pogwiritsa ntchito uvuni yowoneka, ir), kapena ultraviolet (UV).
Makina a Owc akugwira ntchito mokweza mafunde (390 - 750 nm) nthawi zambiri amatchedwa kuti kulumikizana (Vlc). Makina a Vllaps amatenga mwayi wamafuta owala (ma LED) ndipo amatha kugudubuza mwachangu kwambiri popanda zozizwitsa pa zowunikira ndi diso la munthu. VLC ikhoza kugwiritsidwa ntchito pamapulogalamu osiyanasiyana kuphatikiza ma van opanda zingwe, LAN-network. Kumbali inayo, malo opezekapo oyambira a OwC Makina awa nthawi zambiri amagwiritsa ntchito laser ndipo amapereka maulalo okwera mtengo ndi mitengo yotsika mtengo kwambiri (mwachitsanzo 10 GBT / S Provelength) ndikupereka yankho ku Battlecks Boxhals. Chidwi cha Kuyankhulana kwa Ultraviolet (UVC) kukukulirakulira chifukwa cha kupita patsogolo kwaposachedwa mu stop-nthochi yomwe imagwira ntchito mu UV Spectrum (200 - 280 NM). Mumtundu wotchedwa wakuya kwambiri ultraviolet, ma radiation ofiira pamtunda, kupangitsa kuti mapangidwe a cholembera chithunzi cha Photon-Cour-Counter chomwe chimawonjezera mphamvu yolandila popanda kuwonjezera phokoso lowonjezera.
Kwa zaka makumi ambiri, chidwi cha zingwe zopanda waya zachepa kwambiri ku Clandestine ntchito zankhondo ndi mapulogalamu a malo kuphatikizapo maulalo. Mpaka pano, kulowerera kwa msika wa STC kwakhala kochepa, koma Irda ndi njira yopambana yopanda zingwe yopanda zingwe.
Kuchokera pamagawo ophatikizira pakuphatikiza kulumikizana kwa zokhudzana ndi ma satellite zolumikizira, kusiyanasiyana kwa kaya kolumikizana sikugwiritsidwa ntchito m'mapulogalamu osiyanasiyana.
Kulankhulana wopanda zingwe kumatha kugawidwa m'magawo asanu malinga ndi kuchuluka kwa kufalitsa:
1. Maulendo apafupi
Kuyankhulana kumalumikizana ndi ma phukusi okhazikika okhazikika.
2. Mtunda waufupi
Mu muyezo IEEEE 802.15.7, kulumikizana pansi pamadzi pansi pa ma network am'deralo (WABAN) ndi zingwe zapakhomo (WPan).
3. Mndandanda wa sing'anga
Kuyankhulana kwa Indor Ir ndi Kuwonekera kwa IR.
Gawo 4: Kutali
Kulumikizana kolimbikitsa, komwe kumadziwikanso kuti kulumikizana kwaulere kwaulere (FSO).
5. Mtunda wowonjezera
Kuyankhulana kwanthawiyo, makamaka pakati pa ma satelites ndi kukhazikitsidwa kwa magulu a nyenyezi za satellite.
