Lifi imhando yeInternet yekubatanidza inoshandisa tekinoroji inotaridzwa nekufambisa ruzivo kuburikidza nemwenje we LED
Makore mazhinji apfuura ndakanzwa (muna 2016) nemamwe makomuredhi iyo "innovative tekinoroji" iyo Ichachinja nzira yatinobatanidza nayo zvishandiso zvedu pasina waya, ichiva ichi "ndiani aizouya kuzobvisa kushandiswa kweWi-Fi".
LiFi, yaive "pfungwa" yainyanya kutaurwa nezvayo kare ikako, asi ndipo payakagara (kubva pamaonero angu hongu), sezvo yakanzi hunyanzvi hwaive nediki diki uye ndiko kuti kuve kwakavakirwa pachiedza, yaive nezvakawanda zvisingakwanisi kusiyana neWi-Fi.
Zvakanaka, pfungwa yekutaura nezvazvo zvishoma ndeyekuti munguva pfupi yapfuura tekinoroji iyi yatove chiyero uye yaive IEEE yakaburitsa iyo 802.11bb standard yeLiFi
Chii chinonzi LiFi?
Lifi iwaya isina waya yekutaurirana tekinoroji yakavakirwa pachiedza, iyo inovimbisa kukurumidza, yakavimbika, uye yakachengeteka kupfuura Wi-Fi uye 5G, uchishandisa mwenje iripo. LiFi ine zvakanakira munzvimbo umo masaisai eredhiyo akaganhurirwa kana zvisingadikanwi, asi hazvibviriri zvachose.
Nekuburitswa kweiyo, IEEE yakawedzera iyo 802.11bb chiyero kune yakareruka-based wireless communications. Kuburitswa kweiyo standard kwave kugamuchirwa nemakambani eLiFi pasirese.sezvo zvichabatsira kukurumidza kutumira uye kutorwa kweiyo data transmission technology standard.
Vatsigiri veLiFi, kusanganisira pureLiFi, Fraunhofer HHI uye Light Communications 802.11bb Task Group, simbisa zvakanakira kushandisa chiedza panzvimbo peredhiyo (RF). Zvikanzi LiFi inopa "kukurumidza uye kwakavimbika kutaurirana kusina waya ine chengetedzo isingaenzaniswi kana ichienzaniswa neyakajairwa matekinoroji seWi-Fi uye 5G. " Ikozvino iyo IEEE 802.11bb LiFi standard yaburitswa, zvinotarisirwa kuti kudyidzana kwakaratidza pakati peLiFi neWi-Fi masisitimu kuchagadziriswa zvizere.
LiFi haina kungomira kunze kune yainoti inomhanya ye224 GB/s, asi zvakare inovimbisa kuvimbika kwepamusoro uye yakaderera latency uye jitter. Mukuwedzera, "mutsara-we-sight light propagation inovandudza kuchengeteka kuburikidza nekudzivirira kupindira kwemadziro, kuderedza dambudziko rekuvhiringidza uye kuvhara, uye kugonesa kufamba kwemukati nekunyatsoita centimita," Shultz anowedzera.
Iyo IEEE standard 802.11bb inotsanangura iyo yemuviri layer maratidziro uye masisitimu ekuvaka yekutaurirana newireless uchishandisa masaisai akareruka. Iyi chiyero chitsva inoisa hwaro hwekutorwa kwakapararira kweLiFi tekinoroji uye inovhura nzira yekuti LiFi masisitimu idyidzane neiyo WiFi chiyero. Kugadziriswa kwechiyero kwakapedzwa muna Chikumi 2023.
pureLiFi, piyona mukuvandudza tekinoroji yeLiFi, yakatogadzira michina yekutanga pasirese-inoenderana, kusanganisira iyo ichangoburwa Chiedza Antenna YEMWE. Kufanana neketani yeantennas muredhiyo frequency system seWiFi, Chiedza Antenna YEMWE inoenderana neiyo 802.11bb standard.
"pureLiFi inogamuchira kuburitswa kweIEEE 802.11bb standard," akadaro Alistair Banham, CEO we pureLiFi. Ino inguva yakakosha kuindasitiri yeLiFi sezvo ichipa humbowo hwakajeka hwekuendeswa kweLiFi tekinoroji pasi rose. Isu tinodada kuti takaita basa rinotungamira mukusikwa kwayo uye kuve takagadzirira nemidziyo yekutanga yepasirese-inoenderana nemaitiro. Kuvapo kwechiyero chepasi rose kunopa vagadziri vemidziyo chivimbo chekuti vachashandisa LiFi tekinoroji pachiyero.
Iine IEEE 802.11bb yakajairwa, LiFi ine mhinduro yekutanga inosangana nemisika mizhinji senge mutengo wakaderera, kuderera kwesimba rekushandisa, uye mavhoriyamu makuru. Iyo indasitiri inogona kushandisa zvizere mapuroteni eWiFi mune yakareruka svikiro. WiFi traffic kuburitsa, chengetedzo uye kubhurawuza kugona nekudaro inosvika padanho repamusoro.
Zvakakodzera kutaura kuti, LiFi haisi kuzotora Wi-Fi uye 5G dzimwe nzira nedutu (kana mawired network). Sezvo sezvandambotaura pakutanga, tekinoroji iyi ine diki diki, uye ndiko kuti masaisai eredhiyo ane mukana wakajeka kana zvasvika pakutapurirana kuburikidza nezvinhu (semuenzaniso madziro).
Finalmente Kana iwe uchifarira kuziva zvakawanda nezvazvo, unogona kutarisa ruzivo mu inotevera chinongedzo.
Ini ndinofungidzira kuti, pachinzvimbo cheiyo saiti iyo inoshanda, mudziyo unoshandiswa unogadzirisa mwenje wemwenje muchivako, chishandiso ichi chaizoita se router kana modem-router, nepo mwenje wega wega waizokwanisa kutumira ruzivo kune mudziyo uri mukati wiring, ipapo mwenje wega wega waizoita seanodzokorora. Kana mune ramangwana vagadziri vese vemwenje vakagamuchira tekinoroji iyi, zvingave zvakakwana kuve nechiedza mumakamuri kuti ive nekubatanidza isina waya, kunyangwe iyo chaiyo yakakura mukana weWi-Fi mumamiriro ezvinhu andakatsanangura ingave yekukwanisa kubatana murima.
