Optical Wireless Kukurukurirana (OWC) inzira yekutaura kwemaziso umo masaini anofambiswa achishandisa mwenje unooneka, infrared (IR), kana ultraviolet (UV).
OWC masisitimu anoshanda pamafungu anooneka (390 — 750 nm) anowanzo kunzi inooneka mwenje kutaurirana (VLC). VLC masisitimu anotora mukana wemwenje-emitting diode (leds) uye anogona kupuruzira nekumhanya kwakanyanya pasina anooneka mhedzisiro pakubuda kwemwenje uye neziso remunhu. VLC inogona kushandiswa mumhando dzakasiyana dzekushandisa dzinosanganisira isina waya LAN, isina waya yemunhu LAN uye mota networking. Kune rimwe divi, pasi-based point-to-point OWC masisitimu, anozivikanwawo seyemahara space optics (FSO) masisitimu, anoshanda ari pedyo-infrared frequencies (750 — 1600 nm). Aya masisitimu anowanzo shandisa laser emitters uye anopa inodhura-inoshanda protocol transparent links ine yakakwirira data mareti (kureva 10 Gbit/s per wavelength) uye inopa mhinduro inogoneka kune backhaul mabhodhoro. Kufarira ultraviolet kutaurirana (UVC) kuri kukura zvakare nekuda kwekufambira mberi munguva pfupi yapfuura mune yakasimba-nyika magetsi masosi / madetector anoshanda muzuva-mapofu UV spectrum (200 — 280 nm). Mune ino inonzi yakadzika ultraviolet band, mwenje wezuva hauna hanya pasi, zvichiita kuti zvikwanisike kugadzirwa kwephoton-counting detector ine yakakura-munda inogamuchira iyo inowedzera simba rakagamuchirwa pasina kuwedzera imwe ruzha rwemashure.
Kwemakumi emakore, kufarira muOptical Wireless Communications kwakaganhurirwa zvakanyanya kune zvakavanzika zvechiuto zvikumbiro uye nzvimbo yekushandisa inosanganisira intersatellite uye yakadzika nzvimbo yekubatanidza. Kusvika pari zvino, kupinda kwemusika weOWC kwave kushoma, asi IrDA ndiyo yakabudirira kwazvo isina waya pfupi-pfupi yekufambisa mhinduro.
Kubva pakubatana kwemaziso mumasekete akabatanidzwa kusvika kune ekunze interbuilding links kune satellite communications, zvakasiyana-siyana zve optical wireless communication zvinogona kushandiswa mumhando dzakasiyana-siyana dzekutaurirana.
Optical wireless communication inogona kukamurwa muzvikamu zvishanu zvinoenderana nekutapurirana renji:
1. Super madaro mapfupi
Interchip kutaurirana mune akaturikidzana uye akanyatso kurongedza akawanda-chip mapakeji.
2. Nhambo pfupi
Mune mwero IEEE 802.15.7, kutaurirana pasi pemvura pasi pewireless Body Local Area Network (WBAN) uye isina waya Personal Local Area Network (WPAN) application.
3. Pakati pepakati
Indoor IR uye inooneka mwenje kutaurirana (VLC) yeasina waya yenharaunda nharaunda network (WLans) pamwe nemotokari-kune-mota uye mota-kune-infrastructure kutaurirana.
Danho rechina: Kure
Interbuilding yekubatanidza, inozivikanwawo seyemahara nzvimbo optical kutaurirana (FSO).
5. Kuwedzera kureba
Laser kutaurirana muchadenga, kunyanya kune zvinongedzo pakati pemasatellite nekugadzwa kwemapoka enyeredzi.
