ʻO ka Optical Wireless Communication (OWC) kahi ʻano o ka kamaʻilio ʻike ʻana e hoʻouna ʻia nā hōʻailona me ke kukui ʻike ʻole ʻia, infrared (IR), a i ʻole ultraviolet (UV).
ʻO nā ʻōnaehana OWC e hana ana ma nā lōʻihi nalu ʻike ʻia (390 - 750 nm) i kapa ʻia ʻo ia ke kamaʻilio māmā ʻike ʻia (VLC).Hiki i nā ʻōnaehana VLC ke hoʻohana i nā diodes māmā (leds) a hiki ke pulse i nā wikiwiki kiʻekiʻe loa me ka ʻike ʻole ʻia o nā hopena i ka puka kukui a me ka maka o ke kanaka.Hiki ke hoʻohana ʻia ʻo VLC ma kahi ākea o nā noi e pili ana i ka LAN uea, LAN pilikino uea a me ka pūnaewele kaʻa.Ma ka ʻaoʻao ʻē aʻe, ʻo nā ʻōnaehana OWC e pili ana i ka honua, i ʻike ʻia he ʻōnaehana optics free space (FSO), e hana ana ma nā alapine infrared kokoke (750 - 1600 nm).Hoʻohana maʻamau kēia mau ʻōnaehana i nā mea hoʻopuka laser a hāʻawi i nā loulou akaka ka protocol kumu kūʻai me nā helu ʻikepili kiʻekiʻe (ʻo ia hoʻi 10 Gbit/s i kēlā me kēia hawewe) a hāʻawi i kahi hopena kūpono no ka backhaul bottlenecks.Ke ulu nei ka hoihoi i ke kamaʻilio ultraviolet (UVC) ma muli o nā holomua hou i nā kumu kukui paʻa/nā mea ʻike e hana ana i ka spectrum UV makapō lā (200 - 280 nm).I loko o kēia mea i kapa ʻia ʻo deep ultraviolet band, ʻaʻole hiki ke hoʻopololei ʻia ka lā ma ka ʻili o ka honua, e hiki ai ke hoʻolālā i kahi mea ʻike helu kiʻi photon me kahi mea hoʻokipa ākea ākea e hoʻonui ai i ka ikehu i loaʻa me ka hoʻohui ʻole ʻana i ka walaʻau hope.
No nā makahiki he nui, ua kaupalena ʻia ka hoihoi i nā kamaʻilio kelepona ʻike ʻole i nā noi pūʻali huna huna a me nā noi ākea me nā loulou intersatellite a me nā loulou hohonu.I kēia lā, ua kaupalena ʻia ke komo ʻana o ka mākeke nui o OWC, akā ʻo IrDA kahi hopena hoʻouna pōkole pōkole maikaʻi loa.
Mai ka hoʻopili ʻana o ka optical i nā kaapuni i hoʻohui ʻia i nā loulou interbuilding waho i nā kamaʻilio satelite, hiki ke hoʻohana ʻia nā ʻano like ʻole o ke kamaʻilio uea ʻole i loko o nā noi kamaʻilio ākea.
Hiki ke hoʻokaʻawale ʻia ke kamaʻilio kelepona ʻo Optical i ʻelima mau ʻāpana e like me ka laulā hoʻouna:
1. Nā mamao pōkole loa
Kūkākūkā Interchip ma nā pūʻolo puʻupuʻu multi-chip i hoʻopaʻa ʻia a paʻa paʻa.
2. Nā mamao pōkole
Ma ka IEEE 802.15.7 maʻamau, kamaʻilio ma lalo o ka wai ma lalo o ka uea ʻole Body Local Area Network (WBAN) a me nā polokalamu kelepona Personal Local Area Network (WPAN).
3. Laulā waena
IR i loko a me ke kamaʻilio māmā ʻike ʻia (VLC) no nā ʻupena kūloko kūloko (WLans) a me ke kamaʻilio kaʻa-i-kaʻa a me ke kaʻa-i-infrastructure.
KaʻAnuʻu 4: mamao
Interbuilding connectivity, i ʻike ʻia ʻo ka free space optical communication (FSO).
5. Ka mamao hou aku
Ke kamaʻilio laser ma ka lewa, ʻoi aku no nā loulou ma waena o nā satellite a me ka hoʻokumu ʻana i nā constellations satellite.
