Hangarau Li-Fi (super-nohopuku LED Ipurangi): tirohanga whānui, whakaahuatanga, pūrere me opuaraa

Li-Fi - he hou hangarau whakawhiti raraunga e ka faahuru te mahi i roto i te heke mai, te hanga whai wāhitanga maoa hoki te whakamahi i tenei ra, a ka te faaineine ki te riro i te ahumahi multibillion-tāra i te 2022. te whakawhanakehia tēnei wā ki te whakatutuki i te tere o 1Gbit / s, e ka nui te mahi o te aunui Superfast.

marama mōhiohio

Ko te wā Li-Fi i whakaaro e Ahorangi Haraldom Haasom me tohu te tikanga o Pāho pārongo mā te whakamahi i te marama e āhei nui-tere anga-rua kōrero pūkoro, rite Wi-Fi. Ka taea te whakamahi i te reira no te unloading o whatunga tīariari whakahaere i iarere reo irirangi, me te ki ake i to ratou kaha.

Hoki te hononga ultra-nohopuku te whakamahi i te wahi e kitea o te tūāwhiorangi hiko. rere kē ana tēnei i tenei hangarau i te puka o te kōrero ahokore rite Wi-Fi pai-whakapumautia, i roto i te auau tuku iho wāhi.

tuku te raraunga Li-Fi te modulated kaha marama riro photodetector ka tahuri ki te tohu hiko. whakamana puoro i roto i te taua ara e kore e te kanohi tangata kite i te reira.

Hangarau Li-Fi nui-tere kōrero whatu e pā ana ki te kāwai kōrero ahokore, i roto i te tua ki te marama kitea, tae atu pōkākā me te katinga. takoto Ko tōna ahurei i roto i te whakamahi o te pūnaha rama ngā.

Li Fi - arahina Ipurangi Superfast

A, no te tukua nāianei tika te ki arahina-rama, tuku hoki reira he awa on o pūaho o te marama kitea. Na roto i te whakaiti te whakapiki i te wherikotanga o te nāianei taui hoki ranei. Mai te arahina-rama he whakaaro Semiconductor, he nāianei, me i konei, ka taea e te modulated te putanga whatu i tere tiketike rawa. kia kia whāngai te reira i te photodetector, a tahuri hoki ki te nāianei hiko. Ko äta ki te kanohi tangata puoro tiahotanga, me te he rite watea rite irirangi. Mā te tenei tikanga, he rama arahina ahei o whakawhitihia ngā mōhiohio i te tere tiketike.

titau RF kōrero circuitry, Antennas me farii matatini, ia Li-Fi-hangarau nui māmā. whakamahi te reira i tikanga puoro hāngai, pērā i te hunga whai wāhi i roto i te iti-utu pūrere kōrero pōkākā - ngā mana mamao. iti te whakamahi o te kōrero pōkākā te no te mea o te whakaritenga o te haumaru hauora paerewa kanohi i te arahina-rama i te kaha nui o te mura me te whakaatu tere nui.

Light irirangi ranei?

Ka taea e Li-Fi tahuri te rama ki te wāhi uru ahokore i faaauraa ki te pouara Wi-Fi.

I roto i te kōrero tikanga te whakamahi i iarere reo irirangi, engari ko te tino iti o ratou tau. Pūrere - rorohiko, rorohiko, pūreretā, pouaka whakaata atamai, smartphones me papa - me whakataetae mō te hōkaiipurangi. Ko te putanga o atu me te ake mea, te whakamahi i Wi-Fi, mo te tauira, refrigerators, mataaratanga, kāmera, waea pūtau, ko te take o te roa, me te whakaiti i te auau raraunga. whakamahi hangarau Li-Fi-auau ngaru marama, e e 10 000 ngā wā nui atu te auau irirangi.

ngaru irirangi hanga pokanoa hiko e pokanoa ki te mea rererangi me te taputapu, hōhipera, me te pea mōrearea i roto i taua ahumahi rite te mana karihi, te hinu he kōhao me puna hau. Ka whakamahia e Li-Fi marama, haumaru Kāwantanga me e kore e hua i pokanoa hiko.

ngaru irirangi haere na roto i taiepa me tuanui. Light kore e. Ko te rerekētanga i waenganui i te tiaki raraunga Wi-Fi me Li-Fi tenei. Hacker, i waho te whakato, taea ki te hono ki te reo irirangi i roto. Raraunga tuku i runga i Li-Fi, i reira he wātea anake te wahi i te marama e whiti ana.

Paerewa Wi-Fi 802.11a / g whakarato tere tuku ake ki te 54 Mbit / s, a taea te nui haere ake i tenei uara ki te 1 Gbit / s. Kua tae kē te Whare Wānanga o Edinburgh 3 GB / s i taetahi. He tae tonu RGB-arahina taea tuku ake ki te 9 Gbit / s.

Internet o te topuku Li-Fi

whai wāhi whanaketanga o tenei hangarau ki te hua koi i roto i te whakamahi o LED mō ngā take rama.

ko te pai tano Li-Fi mō te ataata me te tikiake oro, ngā ora, a na runga i .. enei mahi hanga titauraa teitei i runga i te hōkaiipurangi o nga awa tāuru, engari e rapu he kaha putaatu iti. Ko te kupu, wewete reira te nuinga o te waka Ipurangi o nga awa auau irirangi ngā, whakawhänui i te taea o te pūkoro me Wi-Fi.

whakamahia Ipurangi Light Li-Fi te i roto i te momo o ngā wāhi:

• Takunga o iarere reo irirangi: e taea te neke whatunga pūkoro kawenga tihi ki Li-Fi. Ko rawa whai hua i runga i te tāuru takere kōrero i reira te nuinga pinepine puta bottlenecks tenei.
• rama Smart: tetahi rama tūmataiti tūmatanui ranei, tae atu ki ngā rama huarahi, e taea te whakamahi rite uru ngā o Li-Fi, me te hanganga ano, te tikanga o te kōrero me te pūoko.
• hononga Mobile: kia hono tika ai rorohiko, smartphones, papa me ētahi atu pūrere pūkoro te whakamahi i Li-Fi. E haere tawhiti whakarato pai, me te kōrero tiakina.
• production mōrearea: Li-Fi-hangarau ko te kē haumaru ki te pokanoa hiko i kōrero auau irirangi i runga i taua taonga kia rite ki maina, otaota matūngahinu.
• Medicine me te hauora: e kore e te marama hua pokanoa hiko, a kahore e reira pokanoa ki taputapu hauora, a kahore e whai wāhi ki matawai MRI.
• Aviation: Ka taea te whakamahi Li-Fi mo mate taimaha, whakaiti i te roa waea me nui haere ngāwari i roto i te whakanohonga o nga nohoanga o taputapu te wehenga pāhihi te wahi i tāuta i te-rama arahina. pūnaha whakangahau i runga i te poari i te kaha ki te mau tonu me te taunekeneke ki ngā pūrere pūkoro o ngā pāhihi.
• Communication i raro i te wai: tika ana ki te absorption kaha o te whakamahi auau tohu i roto i te te wai he koretake. E ngaru acoustic te puta rawa iti, me te whakakorikoria whāngote. whakarato Li-Fi-hangarau he otinga mō kōrero poto-whānui.
• Waka me te Transportation: headlamps kua hua, rama hiku, rama huarahi, tohu me rama waka e whakamahi arahina-rama. Tenei ka taea kōrero i waenganui i waka, me te hanganga ara i roto i nga pūnaha o te haumaru me te whakahaere hokohoko.
• Pū, ratonga mōhiohio rohe, pēnei i pānuitanga me te whakaterenga, e taea ana ki te farii i ngā mōhiohio e pā ana ki te wahi ngā, me te wā.
• E whakamahia LED i roto i maha tākaro e taea te whakamahi mō ngā kōrero iti-utu i waenganui i tākaro pāhekoheko: Taonga tākaro.

tauira Developer

Li-1 e āhei kiritaki ki tere whakawhanake me tono whakamātautau Li-Fi. E tautoko ana te pūrere kōrero Matarua tonu ki te kaha o te 11.5 Mbit / s i te tawhiti o te 3 m, i te whakarato tika rama i runga i tō papamahi. Mahi tawhiti he ti'aturi anake i runga i te kaha o te puna te marama. tuku te pūrere he hononga ohie haumaru ahokore ki te whatunga, ngā ki arahina-rama.

i whakapumautia Li-1 rite te turanga mo kaupapa whakamätau, Li-Fi ngā.

Ko te hua arumoni tuatahi

i faaite nuitia Li-Auahi i te Mobile World Congress i Barcelona i Maehe 2016 pūrere ko te whakatupuranga i muri o tiketike-tere whatunga ahokore tuatahi o te ao e hāngai ana i runga i te marama kitea. tautoko Hangarau Li-Auahi tino teitei kiato atu te rongoā pai Wi-Fi raraunga, ka tango i ona tūturu te haumarutanga pokanoa hiahiatia i te waho.
