Ukuxhumana okungenantambo kwe-Wireless (OWC) kuyindlela yokuxhumana okubonayo lapho amasiginali adluliselwa khona usebenzisa ukukhanya okungathandeki (i-IR) noma i-ultraviolet (UV).
Amasistimu we-OWC asebenza kuma-wavelength abonakalayo (390 - 750 nm) ajwayele ukubizwa ngokuthi yi-Ebonakalayo Shick Communication (VLC). Izinhlelo ze-VLC zisebenzisa amathuba ezi-diode ezikhanyisiwe (ama-LED) futhi zingashintsha ngejubane eliphezulu kakhulu ngaphandle kwemiphumela ebonakalayo ekuphumeni kokukhanyisa kanye neso lomuntu. I-VLC ingasetshenziswa ezinhlobonhlobo zezicelo kufaka phakathi i-wireless lan, i-wireless siqu ye-LAN kanye ne-Nettonet Networking. Ngakolunye uhlangothi, amasistimu we-Ground-based Point-to-Point OWC, eyaziwa nangokuthi ama-Space Space Optics (FSO) ama-Frequency (750 - 1600 NM). Lezi zinhlelo ngokuvamile zisebenzisa ama-laser embitters futhi zinikeze izixhumanisi ezisebenziseka kalula ze-protocol ebonakalayo enamanani aphezulu wedatha (ie 10 gbit / s nge-wavelength ngayinye) futhi anikeze ngesisombululo se-backhaul bootlenecks. Inzalo ekuxhumaneni kwe-ultraviolet (UVC) nayo iyakhula ngenxa yentuthuko yakamuva yemithombo yokukhanya okuqinile / yokuthola izitholi ezisebenza eSun-blind UV Spectrum (200 - 280 NM). Kulesi okuthiwa yi-ultraviolet band ejulile, imisebe yelanga ayinakwa ezingeni lomhlabathi, okwenza ukwakheka komtshina wokubala i-Photon - umthobhisi wensimu enobubanzi obukhulisa amandla atholakele.
Kwaphela amashumishumi eminyaka ukuxhumana kwe-wireless anamali kukhawulelwe ngokuyinhloko kuzicelo zezempi zeClandestine kanye nezinhlelo zokusebenza zesikhala kufaka phakathi izixhumanisi ze-IntertateTatellite kanye nezixhumanisi ezijulile zesikhala. Kuze kube manje, ukungena makethe maphakathi kwamamakethe we-OWC sekunqunyelwe, kepha i-IRDA iyikhambi lokuhambisa elingenantambo eline-wireless elinempumelelo.
Ukusuka ekuxhumekeni kwe-Optical emijikelezweni ehlanganisiwe kuya ezixhumanisi zangaphandle ezihlangene ekuxhumaneni kwe-Satellite, ukuhlukahluka kokuxhumana okungenantambo kwe-Wireless kungasetshenziswa ezinhlelweni ezahlukahlukene zokuxhumana.
Ukuxhumana okungenantambo kwe-wireless kungahlukaniswa ngezigaba ezinhlanu ngokuya ngobubanzi bokuhambisa:
1. Amabanga amafushane amafushane
Ukuxhumana kwe-Interchip kumaphakeji amaningi we-chip amaningi.
2. Amabanga amafushane
Ku-Standard IEEE 802.15.7, Ukuxhumana okungaphansi kwamanzi ngaphansi kwe-wireless body lendawo yendawo (BBAN) kanye ne-Wireless Personal Local Lainer Local Area Network (WPAN) Izicelo.
3. Ibanga eliphakathi
I-IROR IR ne-IR ebonakalayo yokukhanya yokuxhumana (VLC) yamanethiwekhi wendawo engenantambo (ama-WLANS) kanye nokuxhumana kwezimoto nezemoto nasengqalasizinda.
Isinyathelo 4: kude
Ukuxhumana okwakhayo, owaziwa nangokuthi ukuxhumana kwamahhala kwesikhala (FSO).
5. Ibanga elengeziwe
Ukuxhumana kweLaser esikhaleni, ikakhulukazi izixhumanisi phakathi kwama-satellite kanye nokusungulwa kwemilaza ye-satellite.
