Luso Li-Fi (wapamwamba-kudya Internet anatsogolera): mwachidule, maonekedwe, chipangizo ndi chiyembekezo

Li-Fi - latsopano ukuthamana luso zimene atapeza ntchito mtsogolomo, kulenga mwayi kucha ntchito lero, ndipo akukonzekera kukhala yopangira ikhale ya dollar ndi 2022. Panopa akupangidwa kukwaniritsa liwiro 1Gbit / s, umene uposa ntchitoyo burodibandi superfast.

kuwala mudziwe

Mawu akuti Li-Fi kupangidwa ndi Professor Haraldom Haasom ndipo amatanthauza njira kuulutsa nkhani pogwiritsa ntchito kuwala limene limathandiza mkulu-liwiro zina kuti adzipeza mbali mauthenga pafoni, ngati Wi-Fi. Thiabendazole angagwiritsidwe ntchito pa katundu Intaneti wogwila zikugwira ntchito pa mafurikwense wailesi, komanso kuonjezera mphamvu zawo.

Pakuti kugwirizana kopitilira muyeso-kudya pogwiritsa ntchito mbali yapadziko lapansi ya sipekitiramu mu atomu. Izi asiyanika njira imeneyi kuchokera mawonekedwe okhazikika bwino kulankhulana opanda zingwe monga Wi-Fi, pafupipafupi miyambo nawo.

Deta Li-Fi imafalikira modulated kuwala mwamphamvu analandira photodetector ndi n'kukhala ndi chizindikiro magetsi. Kusinthasintha imagwiridwa mu njira yakuti diso la munthu alibe kuzindikira izo.

Technology Li-Fi mkulu-liwiro aya kuwala amatanthauza gulu aya mafoni, amene kuwonjezera kuwala zooneka, kuphatikizapo infuraredi ndi ultraviolet. wapadera umenewu chagona mu ntchito ya dongosolo alipo kuyatsa.

Li Fi - Superfast Internet LED

Pamene panopa mwachindunji umaperekedwa kwa LED-nyale, izo limatulutsa mtsinje azilandira photons kuwala kuwoneka. Ndi kuchepetsa kapena kuwonjezera kuwala kwa apano azisinthidwanso. Popeza LED-nyali ndi michenga yopangira zida zamagetsi zamakono, panopa, motero, linanena bungwe kuwala akhoza modulated pa lalitali kwambiri liwiro. Mwina anatengera photodetector ndi kutembenuza kumbuyo mu panopa magetsi. Kuwala kusinthasintha mawu ndizo imperceptible diso la munthu ndi monga yabwino monga wailesi. Kugwiritsa ntchito njira imeneyi, ndi LED nyali angathe akupereka mauthenga pa liwilo.

RF kulankhulana kumafuna circuitry, tinyanga ndi amalandira zovuta, pamene Li-Fi-luso zosavuta. Limagwiritsa ntchito njira mwachindunji kusinthasintha mawu, monga aja amene zipangizo chotchipa infuraredi kulankhulana - amazilamulira akumidzi. The ntchito kulankhulana infuraredi okha chifukwa cha zofunika za chitetezo thanzi diso mfundo pamene LED-nyali ndi mwamphamvu mkulu wa chowala ndi kusonyeza liwiro lalikulu.

Kuwala kapena wailesi?

Li-Fi angapatutse nyale kukhala mwayi mfundo opanda zingwe ndi kufanizira ndi rauta Wi-Fi.

Mu kulankhulana ochiritsira ntchito mafurikwense wailesi, koma chiwerengero chawo ndi zochepa kwambiri. Zipangizo - makompyuta, Malaputopu, osindikiza mabuku, ma TV anzeru, mafoni ndi miyala - ayenera kupikisana kuti bandiwifi. Zikamera wa zinthu zambiri pogwiritsa ntchito Wi-Fi Mwachitsanzo, refrigerators, ulonda, makamera, matelefoni a m'manja, ndi chifukwa cha kuchedwa ndi kuchepetsa mlingo deta. Li-Fi-pafupipafupi luso amagwiritsa mafunde kuwala, amene 10 000 nthawi woposa pafupipafupi wailesi.

mafunde Radio kulenga mu atomu kuwasokoneza kuti kusokoneza zida ndege ndi zida chipatala ndi zikanavulaza m'mafakitale monga mphamvu za nyukiliya, mafuta pobowola ndi zitsime mpweya. Li-Fi ntchito kuwala, intrinsically otetezedwa ndi sangabereke mu atomu kusokonezedwa.

mafunde Radio kudutsa makoma ndi siling'i. Kuwala sakutero. Izi kusiyana deta chitetezo Wi-Fi ndi Li-Fi. Wolowa mokuba, kunja mbewu, angathe kulumikiza ku wailesi mkati. Data opatsirana pa Li-Fi, pali kupezeka omwe kuwala kuwala.

Standard Wi-Fi 802.11a / g amapereka kufala imathamanga mpaka 54 Mbit / s, ndi mtengo uwu akhoza ziwonjezeke kwa 1 Gbit / s. The University of Edinburgh kale anafika 3 GB / s mu monochrome. A makaka RGB-LED angathe kupatsira mpaka 9 Gbit / s.

Internet ya mababu Li-Fi

Development njira imeneyi chinathandizira kuwonjezeka lakuthwa mu ntchito LEDs zolinga kuyatsa.

Li-Fi ndi zabwino yosayenera kanema ndi kukopera wailesi, zochitika moyo, ndi zina zotero .. ntchito Izi kukakamira okwera pa bandiwifi a ngalande athandizira, koma amafuna osachepera mphamvu ochezeka. Choncho, anamasulidwa kwambiri za magalimoto Internet a alipo njira wailesi pafupipafupi, kuwonjezera mwayi wa m'manja ndi Wi-Fi.

Kuwala Internet Li-Fi ntchito zosiyanasiyana m'madera:

• Wosamasula wa mafurikwense wailesi: Intaneti ma pachimake katundu akhoza ankatembenukira kwa Li-Fi. Izi makamaka zothandiza pa njira kulankhulana athandizira kumene bottlenecks zimachitika kawirikawiri kwambiri.
• Anzeru kuyatsa: iliyonse aumwini kapena apagulu kuunikira, kuphatikizapo nyali msewu, angagwiritsidwe ntchito mfundo mwayi wa Li-Fi, ndi zomangamanga yemweyo, zikutanthauza kulankhulana ndi masensa.
• Mobile kugwirizana: Malaputopu, mafoni, miyala ndi zipangizo zina mafoni akhoza zokhudza ntchito Li-Fi. Kuyenda mtunda amapereka kwambiri ndi kulankhulana kutetezedwa.
• Woopsawo kupanga: Li-Fi-luso ndi njira yosaopsa kuti kulowelela mu atomu kulankhulana wailesi pafupipafupi pa zinthu monga mabomba, petrochemical zomera.
• Medicine ndi thanzi: kuwala Kodi sangabereke mu atomu kuwasokoneza, choncho sikusokoneza zipangizo zachipatala, ndipo si poyera kuti Kujambula Zitsulo zofufuzira zidazo.
• Ndege: Li-Fi angagwiritsidwe ntchito kuwonda, kuchepetsa Kulumikizana m'litali ndi kuchuluka kusinthasintha mu mayikidwe a mipando ya zida chipinda zonyamula kumene LED-nyali akhala anaika. dongosolo zosangalatsa pa bolodi luso kukhalabe ndi kucheza ndi mafoni zipangizo za anthu.
• Communication m'madzi: chifukwa mayamwidwe amphamvu a mbendera pafupipafupi ntchito madzi ndi kosathandiza. mafunde lamayimbidwe ndi wotsika kwambiri matulukidwe ndi kusokoneza nyama zam'madzi. Li-Fi-luso amapereka njira yothetsera aya yochepa osiyanasiyana.
• Magalimoto ndi Mayendedwe: headlamps kale kupangidwa magetsi mchira, magetsi msewu, zizindikiro ndi maloboti kuti ntchito LED-nyali. Zimenezi zimathandiza mgwirizano pakati pa magalimoto ndi zomangamanga msewu mu machitidwe a chitetezo ndi kasamalidwe magalimoto.
• Mwatsatanetsatane, ntchito m'dera zambiri, monga malonda panyanja, amene amalola kulandira mauthenga kugwirizana ndi malo enaake ndi nthawi.
• Zidole: LEDs ntchito zidole ambiri amene angagwiritsidwe ntchito chotchipa mauthenga pakati zidole zokambirana.

zinachitika Wolemba Mapulogalamu

Li-1 amalola makasitomala kuti mofulumira kukhala ndi ntchito mayeso Li-Fi. chipangizo amathandiza zonse duplex kulankhulana ndi mphamvu 11,5 Mbit / s pa mtunda wa 3 m, pamene kupereka kuyatsa chokwanira pa kompyuta yanu. Ntchito mtunda amadalira yekha pa mphamvu ya kuwala gwero. chipangizo amapereka malo kugwirizana osavuta opanda zingwe kwa maukonde, pamodzi LED-magetsi.

Li-1 unakhazikitsidwa monga m'munsi ntchito woyendetsa, kutukula Li-Fi.

Woyamba mankhwala malonda

Li-lawi pamaso anasonyeza pa Mobile World Congress mu Barcelona mu March 2016 chipangizo ndi m'badwo wotsatira wa mkulu-liwiro opanda zingwe maukonde oyamba padziko lonse lapansi pamaziko kuwala kuwoneka. Technology Li-lawi amathandiza apamwamba kwambiri kachulukidwe deta kuposa njira yabwino Wi-Fi ndi chibadidwe wake chitetezo kuchotsa kulowerera osafunika kuchokera kunja. Komanso, osakaniza kuwala ndi opanda zingwe zomangamanga kulankhulana kwambiri zimatithandiza ndipo kumachepetsa mowa mphamvu.

Li-lawi amapereka:

• theka-duplex kulankhulana 10 Mbit / s pa mtunda wa 3 mamita ndi nyali muyezo;
• portability zonse (kunyamula kompyuta wagawo ndi batire) ndi mlingo mkulu deta chifukwa unsembe wandiweyani wa APs Li-Fi;
• m'chitetezo mauthenga opanda zingwe mu chipinda, amene kumatha chiopsezo kutayikira chizindikiro;
• Mipikisano me kupeza mfundo, kupereka bandiwifi wamkulu aliyense wosuta;
• m'chitetezo kulankhulana mafoni mapangidwe kumene mafurikwense wailesi ndi osafunika kapena sakudziwika;
• kusinthasintha kamangidwe Intaneti kulankhulana;
• kuwonjezera osiyanasiyana mafoni ntchito aya;
• ndalama mu kuunikira ndi kutumiza mauthenga zida chifukwa ntchito zomangamanga limodzi.

Denga wagawo:

• Data ndi mphamvu umaperekedwa kudzera muyezo Efaneti-doko.
• Easy unsembe.
• Iwo olumikizidwa kwa LED-nyale, maselo atto-n'kupanga.
• Angapo mwayi.
• Yosalala kusintha pakati pa mfundo mwayi.

Table Unit:

• Kugwirizana kwa chipangizo kasitomala kudzera USB-doko.
• 10 Mbit / s uplink ku gawo infuraredi wa denga.
• Swivel mutu transceiver zikhoza kusintha ndi wosuta.
• Battery mphamvu ndi portability.

The yachangu, kalemba kakang'ono ndipo ambiri atetezedwe

LiFi-X ndi chitukuko cha dongosolo Li-lawi. Timatha inu atumiza zopezera zonse ndi mosiyana mankhwala alipo, kuchirikiza mwayi angapo, akungoyendayenda, zonse zoyendayenda, ndi zophweka chomwecho ntchito. Kumasiyana ndi Baibulo yapita wa kulankhula ndi mgwirizano odzaza-duplex pa liwiro la 40 Mbit / s mu kuyenda onse akutuluka ndi malangizo athandizira, ndi wathunthu operekedwa ndi kunyamula USB-siteshoni.

The mwayi mfundo LiFi-X:

• Mphamvu pa PoE kapena PLC.
