Chiedza Kuvimbika kwekombiyuta inovaka pamusoro pehutano hweWi-Fi kutumira data nokukurumidza
Li-Fi inzira yekutumira mashoko zvakakurumidza zvikuru. Panzvimbo yekushandisa zviratidzo zveredhiyo kuti utumidze ruzivo - iyo iyo iyo Wi-Fi inoshandisa - Light Fidelity teknolojia, inowanzonzi Li-Fi, inoshandisa kuoneka kwezuva chiedza.
Li-Fi Yakapiwa Rini?
Li-Fi yakasikwa seimwe nzira yemavhidhiyo (RF) based network technologies. Sezvo kusina mitambo yekutengesa yakafuridzirwa mukuzivikanwa, zvatova zvakaoma kutakura zvinhu zvakawanda izvi zvematare pamusoro pehuwandu huwandu hweredhiyo dzemahara dzinowanika.
Harald Hass, mumwe anotsvakurudza paYunivhesiti yeEdinburgh (Scotland), akanzi Baba vaLi-Fi nokuda kwekuedza kwake mukufambisa iyi teknolojia. Hurukuro yake yeTED mugore ra2011 yakaunza Li-Fi neYunivhesiti D-Chiedza purojekiti muchiitiko chepachivande kwekutanga, ichichitumidza kuti "data kuburikidza nekujekesa."
Iyo Li-Fi uye Chiedza Chaicho Chikurukurirana (VLC) Basa
Li-Fi inzira yeVisible Light Communication (VLC) . Kushandisa mwenje semafungiro ekukurukurirana haisi pfungwa itsva, inotora makore anopfuura zana. NeVLC, kuchinja muhukuru hwechiedza kunogona kushandiswa kutaurira ruzivo rwekodhi.
Mafomu ekutanga eVLC akashandisa zvigadzirwa zvemagetsi zvemagetsi asi aisagona kuwana zvikwiriso zvikuru zvemadhora. IEEE yeboka rinoshanda 802.15.7 rinoramba richishanda pamabhizimisi eVLC.
Li-Fi anoshandisa machena chiedza-emitting diodes (LEDs) panzvimbo yepasiporesi fluorescent kana incandescent bulbs. A Li-Fi network inoshandura kuwedzera kwema LEDs kumusoro nekudzika panguva yakakura kwazvo (inokurumidza kuti ziso revanhu rione) kutumira data, rudzi rwe hyper-speed morse code.
Saizvozvowo neWi-Fi, Li-Fi mitambo inoda mapepa akakwana ekuwana Li-Fi kuronga chitima pakati pezvigadzirwa. Maikirwo emakirini anofanira kunge akavakwa neine Li-Fi wireless adapter, zvichida yakagadzirwa-chip kana dongle .
Kubatsirwa kweLi-Fi Technology Uye Indaneti
Li-Fi mitambo inopesana nekupindira kwevhepfenyuro yevhepfenyuro, kuwedzerwa kukurukurwa kunokosha mumisha sezvo kuzivikanwa kweIndaneti yezvinhu (IoT) uye mamwe magetsi asina kushandiswa achiri kuramba achiwedzera. Uyezve, iyo yakawanda isina wireless spectrum (mararamiro ehutachiona anowanikwa) nechiedza chinoratidzika kupfuura zvakanyanya zveyerevhizheni yakafanana neyo inoshandiswa kuWi-Fi - iyo inowanzonzi-inodhindwa inodhindwa zvinodarika 10 000 zvakanyanya. Izvi zvinoreva Li-Fi mitambo inofanirwa kuti inofanirwa kuva nehukuru hukuru pamusoro peWi-Fi inokwanisa kukwira kumusoro kuti inotsigire mitambo ine zvakawanda zvepamutambo.
Li-Fi miterevhizheni inogadzirirwa kushandiswa kwechiedza chekugadziriswa kwekare mumisha nedzimwe zvivako, zvichiita kuti dzive shoma kuisa. Zvinoshanda zvakadai sehutachiona husina simba hunoshandisa wavelengths of chiedza risingabviri kumeso evanhu, asi Li-Fi haifaniri kujekesa kuparadzanisa chiedza.
Nemhaka yekuti kutumirwa kunongogumira kune dzimwe nzvimbo umo chiedza chingapinda mukati, Li-Fi inopa kuchengetedza kwekuchengetedzeka kwepanyika pamusoro pe Wi-Fi iyo inoratidza zviratidzo zviri nyore (uye kazhinji nekugadzira) inopinda mumasvingo nepasi.
Vaya vanopokana nemishonga yehutano hwehuwandu hwehuwandu hweWi-Fi kuvanhu huchawana Li-Fi yechinhu chinotapira.
Inokurumidza sei Li-Fi?
Dhiyabhorosi miedzo inoratidza Li-Fi inogona kushanda pamatunhu makuru kwazvo; imwe kuedza yakayera kuwedzerwa kwemashoko ye 224 Gbps (gigabits, kwete megabits). Kunyange apo zvinobatsira zve network network protocol (zvakadai sekuvhara ) zvinotorwa, Li-Fi inonyanya, yakakurumidza.
Matambudziko ane Li-Fi
Li-Fi haikwanisi kushanda zvakanaka kunze kwekushungurudzwa kwezuva. Li-Fi connections haigoni kupinda mukati memasvingo nezvinhu zvinodzivirira chiedza.
Wi-Fi inonakidzwa kare nechepamusoro-soro yakakosha yeimba uye mabhizimusi masangano pasi rose. Kuwedzera pane izvo zvipi zvinopa Wi-Fi zvinoda kupa vatengi chikonzero chinokurudzira chekuvandudza uye nekudhura kwakaderera. Zvimwe zvikwata zvinotofanira kuwedzerwa kuma LED kuitira kuti vashandise zvekutaura kweLi-Fi kunofanira kugamuchirwa nemagetsi makuru ekugadzira.
Kunyange zvazvo Li-FI yakave nemigumisiro yakawanda kubva kuongororo yebazi, zvingave zvichiri makore kurega kuwanikwa zvakanyanya kune vatengi.
