Li-Fi technology (super-kutsanya Internet akatungamirira): zvayakaita, description, mudziyo uye tarisiro

Li-Fi - mutsva date kuchinjirwa michina kuti zvichaita revolutionize yebhizimisi mune remangwana, ndinosika mikana zvaibva kuti kushandiswa nhasi, uye ari kugadzirira kuva multibillion emadhora ne 2022. Ano yakatanga kuzadzisa kumhanya 1Gbit / s, izvo ichapfuura chokupika superfast Broadband.

mashoko chiedza

Izwi Li-Fi akanga afunga Professor Haraldom Haasom uye anoreva nzira nhepfenyuro mashoko kushandisa chiedza kuti inogonesa mukuru-nokukurumidza bi achitaura pafoni kukurukurirana, kufanana Wi-Fi. Rinogona kushandiswa vachidzikisa pamusoro yaivapo network uchishanda panguva redhiyo frequencies, uyewo kuwedzera kugona kwavo.

For Ultra-kutsanya kubatana anoshandisa chinooneka chikamu remagetsi chakarondedzera. Izvi chinosiyanisa Michina iyi kubva zvakanaka isingachinji chimiro kukurukurirana pasina tambo sezvo Wi-Fi, mune zvetsika maitikiro zvinobatanidzwa.

The Li-Fi mashoko ari inoparadzirwa modulated chiedza kuchinyanya vakagamuchira photodetector uye vagotendeuka vapinda zvemagetsi chiratidzo. Kusiyanisa inzwi rinoitwa kuita kuti ziso munhu asingadi kurinzwisisa.

Technology Li-Fi mukuru-nokukurumidza Manyiminya kukurukurirana rinoreva Wireless kukurukurirana muchikwata, izvo kunze chiedza inooneka, kusanganisira michini uye ultraviolet. kusiyana kwayo iri kushandisa zviripo okuvimba hurongwa.

Li Fi - Superfast Internet akatungamirira

Kana yakananga ano ari kusvitsa kuti akatungamirira-rambi, izvozvo inongorira vaingoramba pamusoro photons chiedza zvinooneka. Akaroromesawo kana kuwedzera nokupenya kuitika achichinjwawo. Sezvo akatungamirira-marambi vari semiconductor mano, mumwe kuitika, uye nokudaro, kuti Manyiminya goho inogona modulated panguva chaizvo nokukurumidza. Zvinogona vava photodetector uye vagotendeuka kumashure zvemagetsi iyezvino. Nokupenya vachisiyanisa inzwi riri imperceptible kuvanhu ziso uye kwakafanana nyore sezvo redhiyo. Tichishandisa nzira iyi, imwe zvakatungamirira rambi inokwanisa achitumira mashoko ari kumhanya.

RF kutaurirana kunoda hushande, antennas uye vagamuchiri yakaoma, apo Li-Fi-zvemichina nyore zvikuru. Inoshandisa yakananga vachisiyanisa inzwi unyanzvi, akadai avo anobatanidzwa rweruzhinji michini kukurukura mano - kure chidhiraivho. Kushandiswa michini iri shoma nokuda yakachengeteka zvinodiwa utsanana dzemunharaunda meso, nepo akatungamirira-marambi vane matunhu luminous zvakanyanya uye kuratidza nokukurumidza zvikuru.

Light kana redhiyo?

Li-Fi anogona kutsausa mwenje kuva Wireless kuwana pfungwa nomuenzaniso pamwe router Wi-Fi.

Mugore kwakajairika kukurukurirana uchishandisa redhiyo frequencies, asi nhamba yavo ishoma zvikuru. Mano - makombiyuta, Laptops, vaidhinda, akangwara TVs, smartphones uye mahwendefa - vanofanira kukwikwidzana kuti throughput. The chidzoke zvinhu zvakawanda, achishandisa Wi-Fi Somuenzaniso, sefiriji, wachi, makamera, maserura, ari kukonzera kunonoka uye kuderedza date unodiwa. Li-Fi-Frequency zvemichina anoshandisa chiedza mafungu, idzo 10 000 nguva kupfuura redhiyo maitikiro.

Radio mafungu kusika remagetsi chipingaidzo kuti kupindira zviridzwa ndege uye zvokushandisa, chipatara uye nengozi mumaindasitiri akadai simba renyukireya, mafuta kuchera uye matsime gasi. Li-Fi anoshandisa chiedza, intrinsically wakachengeteka uye haaiti remagetsi chipingaidzo.

Radio mafungu nomunyika masvingo uye ceilings. Chiedza haadaro. Ndiwo musiyano pakati date kudzivirira Wi-Fi uye Li-Fi. Hacker, kunze chirimwa, kukwanisa kubatanidza redhiyo mukati. Data chinopfuudzwa musi Li-Fi, pane kuwanika chete apo chiedza chinovhenekera.

Standard Wi-Fi 802.11a / d kunopa yedzimudzangara aimhanya anosvika 54 Mbit / s, uye kukosha ichi kunogona yakawedzera kusvika 1 Gbit / s. The University of Edinburgh kare yakasvika 3 GB / s mu monochrome. A ruvara yakazara RGB-akatungamirira zvinogona kutapurira kusvika 9 Gbit / s.

Internet ine Mabumba Li-Fi

Development ruzivo urwu vakabatsira kuti unopinza kuwedzera kushandiswa LEDs okuvimba zvinangwa.

Li-Fi ari yakanakisisa wakanyatsokodzera kuti mavhidhiyo uye makaseti downloads, zviitiko vachirarama, uye zvichingodaro .. mabasa aya kuti yakakwirira zvinoda pamusoro bandwidth pakati mazano migero, asi zvinoda risingamboshandisi ichibviswa simba. Saka akasunungura vakawanda Internet motokari aripo redhiyo kakawanda mugero, wokukudza yaibvira Mobile uye Wi-Fi.

Light Internet Li-Fi rinoshandiswa nenzira dzakasiyana-siyana munzvimbo:

• Waiti redhiyo frequencies: cellular network yepamusorosoro mitoro zvinogona zvava Li-Fi. Izvi zvinonyatsoshanda pamusoro mazano kukurukurirana migero apo bottlenecks kuitika inonyanyoshandiswa.
• Smart chiedza: chero private kana voruzhinji chiedza, kusanganisira mumigwagwa marambi, dzinogona kushandiswa kuwana pfungwa Li-Fi, pamwe chete kwezvivako, zvinoreva yokukurukurirana uye sensors.
• Mobile kubatana: Laptops, smartphones, mahwendefa nezvimwe Mobile namano anogona chokuita uchishandisa Li-Fi. Kufamba kure inopa wakanakisisa uye kuchengetedzwa kukurukurirana.
• Ngozi Kugadzirwa: Li-Fi-zvemichina chinhu ngozi pane remagetsi kupindira redhiyo Frequency kutaurirana pamusoro zvinhu zvakadai zvimbambaira, petrochemical zvirimwa.
• Mushonga uye utano: chiedza Haibudisi remagetsi chipingaidzo, uye saka hazvirevi kuvhiringidza wezvokurapa zvokushandisa, uye havasi pachena kuna MRI scanners.
• Aviation: Li-Fi inogona kushandiswa uremu, achidzikisa wiring urefu uye yakawedzera kuchinja mune placement pakati zvigaro kwemashoko mufambi mupanda umo akatungamirira-mwenje kunge yakaiswa. varaidzo mamiriro mungarava kukwanisa kuramba uye kushamwaridzana Mobile mano vanhu.
• Communication pasi mvura, nokuda simba Absorção de Água ari chiratidzo kakawanda kushandiswa mumvura zvisingaiti. Acoustic mafungu vane pasi kwazvo throughput uye kanganisa zvomumvura mhuka. Li-Fi-zvemichina rinopa mhinduro NFC.
• Vehicles uye Chifambiso: kare yakabereka headlamps, muswe zviedza, mumigwagwa mwenje, zviratidzo uye motokari mwenje kuti kushandisa akatungamirira-mwenje. Izvi zvinoita kutaurirana pakati nemotokari uye mugwagwa kwezvivako ari mugadziriro vakachengeteka uye motokari zvakanaka.
• Zvakarurama, zvomunharaunda mashoko mabasa, akadai pakushambadzira uye navigation, izvo anobvumira kugamuchira mashoko chokuita nenzvimbo chaiyo uye nguva.
• Toys: LEDs zvinoshandiswa matoyi akawanda anogona kushandiswa rweruzhinji kukurukurirana pakati nematoyi dyidzana.

kumumvuri Developer

Li-1st achibvumira vatengi kuti nokukurumidza kuumba uye bvunzo zvikumbiro Li-Fi. The mudziyo inotsigira zvizere duplex kutaura inogona 11.5 Mbit / s chinhambwe 3 m, apo kupa zvakakwana chiedza yagadzirwa pa-desktop pako. Kushanda kure runotsamira chete pamusoro nesimba chiedza kunobva. The mudziyo inopa nyore yakachengeteka Wireless riine pomumbure, pamwe akatungamirira-mwenje.

Li-1st rakavambwa sezvo muzinda mutyairi mapurojekiti, Li-Fi Developers.

The yokutanga vezvokutengeserana chigadzirwa

Li-Flame kwakaratidzwa pachena panguva Mobile World Congress muBarcelona muna March 2016 mudziyo ndiyo runotevera kwenyika yokutanga mukuru-nokukurumidza Wireless rezvebonde inobva chiedza anooneka. Technology Li-Flame inotsigira yekudyidzana yepamusoro umbowo arambe achirema pane zvakanaka mukugadzirisa Wi-Fi, uye ayo yokusafa The kuchengeteka kubvisa kupindira pasingadiwi kubva kunze.
