Li-Fi technology (LED Internet super-degdeg ah): dulmar, sharaxaad, qalab iyo rajada

Li-Fi - tiknoolajiyadda xawilaadda xogta cusub oo wax ka beddeli doono ganacsiga mustaqbalka, maanta abuuraya fursado u bislaaday loo isticmaalo, iyo isku diyaarinaya in ay noqdaan warshadaha Balaayiin Dollar ah by 2022. Currently ee la sameeyey si loo gaaro xawaaraha 1Gbit / s, kuwaas oo kor maraysa waxqabadka broadband superfast.

macluumaad light

Ereyga Li-Fi ayaa lagu soo hindiseen Professor Haraldom Haasom iyo tusinaysaa hab ka mid ah baahinta macluumaadka la isticmaalayo iftiinka oo awood-xawaaraha sare ee isgaarsiinta mobile bi-jiho, sida Wi-Fi. Waxaa loo isticmaali karaa dejinta shabakadaha jira howlgala mawjadaha raadiyaha, iyo sidoo kale in la kordhiyo awoodooda.

Wixii la xidhiidha aalladda degdeg ah iyadoo la isticmaalayo qayb ka mid ah la arki karo oo ah qaybaha ugu electromagnetic. Tani waxay kala technology this ka foomka si fiican loo aasaasay oo ah xidhiidhka wireless sida Wi-Fi, inta jeer dhaqameed lug.

Xogta Li-Fi loo kala qaado meyxaanahaa xoojinta iftiin helay photodetector iyo beddelay signal koronto. Isbedbeddelka waxaa la sameeyaa hab in isha aadanaha ma Oga ah.

Technology Li-Fi-xawaaraha sare ee isgaarsiinta indhaha loola jeedaa qaybta isgaarsiinta wireless, kaas oo lagu daro iftiin muuqda, oo ay ku jiraan infrared iyo ultraviolet. Its yadiisa been in isticmaalka nidaamka nalalka jira.

Li Fi - Internet Superfast LED

Marka hadda si toos ah waxaa bixisey in LED-laambad, shanqarta il joogta ah photons iftiinka arki karo. By yareynta ama kordhaya dhalaalka hadda sidoo kale bedeshaa. Tan iyo-laambadihii LED ku jira hindisooyin Semiconductor, hadda ah, iyo halkan, wax soo saarka indhaha la meyxaanahaa karaa xawaare aad u sarreeya. Waxaa la ansixiyay laga yaabaa photodetector iyo diinta dib hadda korontada. isbedbeddelka dhalaalka waa dismo isha aadanaha iyo waa sida ku haboon sida raadiyaha. Isticmaalka this farsamo, siraad LED awood u gudbinta macluumaadka ee xawaaraha sare.

isgaarsiinta RF u baahan circuitry, anteenooyinkooda iyo qaateyaasha adag, halka Li-Fi-technology inta badan ka sahlan. Waxa uu isticmaalaa farsamooyin isbedbeddelka toos ah, sida kuwa ku lugta leh qiimo jaban qalabka isgaarsiinta infrared - kontaroolada fog. Isticmaalka isgaarsiinta infrared waxaa xadiday sababta oo ah shuruudaha ammaanka caafimaadka heerarka isha halka-laambadihii LED leeyihiin xoojinta sare oo siyasad iyo tusi xawaaraha weyn.

Light ama raadiyaha?

Li-Fi ka leexin kara laambad galay helitaanka a dhibic wireless isu ekaysiinta la router ee Wi-Fi.

In isgaarsiinta ee caadiga ah la isticmaalayo mawjadaha raadiyaha, laakiin tiradoodu aad u yar. Qalabka - kombiyuutarada, laptops, madbacadaha, telefishinada smart, casriga ah iyo kiniiniyada - waa tartamaan bandwidth. ah ee wax badan oo dheeraad ah, iyadoo la isticmaalayo Wi-Fi, tusaale ahaan, qaboojiyaha, soo jeedo, kamaradaha, taleefannada gacanta, waa sabab ka mid ah dib u dhac iyo in la yareeyo heerka xogta. technology Li-Fi-noqnoqoshada isticmaala mowjado iftiin, kuwaas oo ah 10 000 jeer ka weyn yahay inta jeer ee raadiyaha.

hirarka Radio abuuro faragelinta electromagnetic in faragelin alaabtii diyaaradaha iyo qalab, isbitaalka iyo aadka u halista ah ee warshadaha sida nukliyeerka, saliid shidaal qodista ceelasha iyo gaaska. Li-Fi isticmaalaa iftiin, oo asal ammaan oo aanu soo saari faragelinta electromagnetic.

hirarka Radio dhex mari darbiyada iyo saqafka. Light ma. Tani waa faraqa u dhexeeya ilaalinta xogta Wi-Fi iyo Li-Fi. Hacker, baxsan geedka, ay awoodaan in ay ku xidhmaan radio gudaha. Xogta lagu kala qaado on Li-Fi, waxaa jira oo kaliya laga heli karaa Halkaas oo iftiinku iftiimay.

Standard Wi-Fi 802.11a / g bixisaa xawaare gudbinta ilaa 54 Mbit / s, iyo qiimaha this waa la kordhin karaa ilaa 1 Gbit / s. The University of Edinburgh horay u gaareen 3 GB / s in monochrome. midabka A buuxa RGB-LED gudbin kartaa ilaa 9 Gbit / s.

Internet of nalalka Li-Fi

Horumarinta of technology this ka qayb qaatay kor u kac wayn ee isticmaalka Kokes ujeedooyin iftiiminta.

Li-Fi waxaa ugu wanaagsan ee aduu video iyo downloads audio, dhacdooyinka live, iyo wixii la mid ah .. Shaqooyinkaasi waxaa ka sameeyaan dalabyada sare on bandwidth ee channels talooyin ah, laakiin waxay u baahan yihiin awood ugu yaraan xilka. Sidaas darteed, waxaa la sii daayay inta badan gaadiidka Internet ah channels inta jeer ee radio jira, ballaarinta fursadaha mobile iyo Wi-Fi.

Internet Light Li-Fi waxaa loo isticmaalaa noocyo kala duwan oo meelo:

• Dhaafka ee mawjadaha raadiyaha: shabakadaha gacanta ugu rarataan culaysyo peak lagu wareejiyay karaan si ay Li-Fi. Tani waa gaar ahaan wax ku ool on channels ee xidhiidhka la gelin meesha ciriiriga badi ku dhacaan.
• nalalka Smart: nalalka kasta oo gaar ah ama dadweynaha, oo ay ku jiraan laambadihii jidadka, waxaa loo isticmaali karaa sida dhibcood helaan of Li-Fi, la kaabayaasha isla, oo macnaheedu yahay ee isgaarsiinta iyo dareemayaal.
• xidhiidh Mobile: laptops, casriga ah, kiniin iyo qalab kale oo mobile laga yaabaa in si toos ah ugu xiran oo isticmaalaya Li-Fi. Socodka fog bixisaa fiican iyo isgaarsiinta ah la ilaaliyo.
• wax soo saarka Khatarta leh: Li-Fi-technology waa ka duwan oo amaan ah si ay faragelin electromagnetic ka isgaarsiinta inta jeer ee radio on alaabta sida miinada, dhirta kiimikada.
• Medicine iyo caafimaadka: nuurka ma keento faragelin electromagnetic, oo sidaas daraaddeed ma faragelin qalab caafimaad, iyo ma bandhigi scanners MRI.
• Aviation: Li-Fi loo isticmaali karaa miisaan lumis, yaraynta dhererka taararka iyo dabacsanaan kordhay meelaynta kursiyadii qalabka qol rakaabka halkaas oo-laambadihii LED ayaa lagu rakibay ah. nidaamka madadaalada on board awoodda si ay u ilaaliyaan oo la macaamilaan qalab mobile rakaabka.
• Isgaarsiinta hoos biyo, ay sabab u tahay nuugista xoogga leh ee isticmaalka inta jeer signalka biyo shaqayn karto. hirarka loomana baahno leeyihiin dhex ah mid aad u yar oo ku dhibin nuujiya badda. Li-Fi-technology waxay bixisaa xal isgaarsiinta-duwan oo gaaban.
• Baabuurta iyo Gaadiidka: headlamps hore u soo saaray, nalalka iyo badhidii, nalalka jidadka, calaamadaha iyo nalalka gaadiidka isticmaala-laambadihii LED. Tani waxay awood u xiriirka ka dhexeeya gaadiidka iyo dhismaha waddooyinka ee nidaamka ammaanka iyo maamulka gaadiidka.
• Sax, adeegyada macluumaadka maxalliga ah, sida advertising iyo navigation, kaas oo u ogolaanaya in ay helaan macluumaad la xiriira meel gaar ah iyo waqti.
• Alaabta: Kokes ku waxaa loo isticmaalaa in alaabta lagu ciyaaro badan oo loo isticmaali karaa isgaarsiinta kharashka yar ee u dhexeeya alaabta lagu interactive.

Developer noocooda

Li-1aad macaamiisha u oggolaanaya inay si degdeg ah u horumariyaan iyo codsiyada imtixaanka Li-Fi. Qalabka wuxuu u taageertaa isgaarsiinta dabaq buuxa la awooda 11.5 Mbit / s fogaan ah 3 m, halka bixinta nalalka ku filan on your desktop. Ka shaqeynta meel fog ku xidhan tahay oo kaliya on xoogga isha iftiinka. Qalabka wuxuu u bixiyaa a xidhiidha fudud ammaan wireless shabakadda, oo ay weheliso LED-nalalka.

Li-1-dii waxaa la aasaasay sida saldhig u ah mashruuc tijaabo ah, horumarinta Li-Fi.
