Urashaka kumenya niba umukunzi wawe akunda gukina imikino yo kuri mudasobwa? Reka nkubwire inama, ushobora kugenzura ko mudasobwa ye ifite umuyoboro wa interineti cyangwa idakoresha umuyoboro wa interineti. Kubera ko abahungu bafite ibisabwa byinshi ku muvuduko wa interineti no gutinda mu gihe bakina imikino, kandi WiFi nyinshi zo mu rugo ntabwo zishobora kubikora nubwo umuvuduko wa interineti wa interineti waba wihuta bihagije, bityo abahungu bakunze gukina imikino bakunda guhitamo gukoresha interineti kugira ngo barebe ko urubuga rwabo rudahindagurika kandi rwihuse.
Ibi kandi bigaragaza ibibazo byo guhuza WiFi: gutinda cyane no kudahuzagurika, bigaragara cyane ku bakoresha benshi icyarimwe, ariko iki kibazo kizarushaho kunozwa cyane iyo WiFi 6 igeze. Ibi biterwa nuko WiFi 5, ikoreshwa n'abantu benshi, ikoresha ikoranabuhanga rya OFDM, mu gihe WiFi 6 ikoresha ikoranabuhanga rya OFDMA. Itandukaniro riri hagati y'ubu buryo bubiri rishobora kugaragazwa mu buryo bw'ishusho:
Ku muhanda ushobora kwakira imodoka imwe gusa, OFDMA ishobora kohereza terminal nyinshi icyarimwe, ikagabanya umurongo n'umubyigano, ikongerera ubushobozi bwo gukora no kugabanya igihe cyo gutinda. OFDMA igabanya umuyoboro wa wireless mo imiyoboro myinshi mu gice cy'umuyoboro, kugira ngo abakoresha benshi bashobore kohereza amakuru icyarimwe icyarimwe muri buri gihe, ibi bikongera imikorere kandi bigabanya gutinda kw'imirongo.
WIFI 6 imaze kugera ku ntera kuva yatangira gukoreshwa, kuko abantu basaba imiyoboro myinshi idafite insinga mu ngo. Ibikoresho birenga miliyari 2 bya Wi-Fi 6 byoherejwe mu mpera za 2021, bingana na 50% by'ibyoherezwa byose bya Wi-Fi, kandi uwo mubare uzagera kuri miliyari 5.2 mu 2025, nk'uko bivugwa n'ikigo cy'isesengura cya IDC.
Nubwo Wi-Fi 6 yibanze ku bunararibonye bw'abakoresha mu bihe by'ubucucike bwinshi, porogaramu nshya zagaragaye mu myaka ya vuba aha zisaba uburyo bwo gukoresha no gutinda cyane, nka videwo zigezweho cyane nka videwo za 4K na 8K, gukorera kure, gukorera kuri interineti, n'imikino ya VR / AR. Ibihangange mu ikoranabuhanga nabyo birabona ibi bibazo, kandi Wi-Fi 7, itanga umuvuduko ukabije, ubushobozi bwo hejuru no gutinda guke, iri ku mwanya wa mbere. Reka dufate urugero rwa Wi-Fi 7 ya Qualcomm maze tuganire ku byo Wi-Fi 7 yateje imbere.
Wi-fi 7: Byose bifasha mu gihe gito cyo gutinda
1. Ubugari bw'umuyoboro (bandwidth) buri hejuru
Na none, fata imihanda. Wi-fi 6 ishyigikira cyane imiyoboro ya 2.4ghz na 5ghz, ariko umuhanda wa 2.4ghz wakoreshejwe na Wi-Fi yo hambere n'izindi koranabuhanga zitagira insinga nka Bluetooth, bityo uba wuzuye cyane. Imihanda iri kuri 5GHz ni minini kandi idafite abantu benshi ugereranyije na 2.4ghz, ibyo bikaba bituma umuvuduko wihuta n'ubushobozi bwinshi. Wi-fi 7 ishyigikira kandi imiyoboro ya 6GHz iri hejuru y'iyi miyoboro ibiri, yongera ubugari bw'umuyoboro umwe kuva kuri Wi-Fi 6′s 160MHz kugeza kuri 320MHz (ishobora gutwara ibintu byinshi icyarimwe). Icyo gihe, Wi-Fi 7 izaba ifite igipimo cyo hejuru cyo kohereza amakuru kirenga 40Gbps, inshuro enye hejuru ya Wi-Fi 6E.
2. Uburyo bwo gukoresha amasano menshi
Mbere ya Wi-Fi 7, abakoresha bashoboraga gukoresha umuhanda umwe gusa ujyanye n'ibyo bakeneye, ariko igisubizo cya Wi-Fi 7 cya Qualcomm cyarushijeho kwimura imipaka ya Wi-Fi: mu gihe kizaza, imiyoboro yose uko ari itatu izabasha gukora icyarimwe, bigabanye umubyigano. Byongeye kandi, hashingiwe ku mikorere ya multi-link, abakoresha bashobora guhuza binyuze mu miyoboro myinshi, bakabibyaza umusaruro kugira ngo birinde umubyigano. Urugero, niba hari urujya n'uruza rw'abantu kuri imwe muri iyo miyoboro, igikoresho gishobora gukoresha indi miyoboro, bigatuma umuvuduko ugabanuka. Hagati aho, bitewe n'uko uturere dutandukanye tuboneka, multi-link ishobora gukoresha imiyoboro ibiri muri 5GHz cyangwa uruvange rw'imiyoboro ibiri muri 5GHz na 6GHz.
3. Umuyoboro w'Amahuriro
Nkuko byavuzwe haruguru, umuyoboro wa Wi-Fi 7 wongerewe ugera kuri 320MHz (ubugari bw'imodoka). Kuri bande ya 5GHz, nta bande ya 320MHz ihoraho ihari, bityo akarere ka 6GHz ni ko konyine gashobora gushyigikira ubu buryo buhoraho. Hamwe n'imikorere ya bande nini ihuza inshuro nyinshi icyarimwe, bande ebyiri zishobora guhurizwa icyarimwe kugira ngo zikusanye uburyo bwo kunyuramo imiyoboro ibiri, ni ukuvuga ko ibimenyetso bibiri bya 160MHz bishobora guhuzwa kugira ngo bikore umuyoboro ukoresha 320MHz (ubugari burambuye). Muri ubu buryo, igihugu nk'icyacu, kitaragena umuyoboro wa 6GHz, gishobora kandi gutanga umuyoboro mugari uhagije wo kugera ku muyoboro mwinshi cyane mu bihe byuzuye.
4. 4K QAM
Uburyo bwo gukoresha Wi-Fi 6 mu buryo bworoshye ni 1024-QAM, mu gihe Wi-Fi 7 ishobora kugera kuri 4K QAM. Muri ubu buryo, igipimo cyo hejuru gishobora kongerwa kugira ngo hongerwe ubushobozi bwo gukoresha amakuru n'ubushobozi bwo kuyakoresha, kandi umuvuduko wa nyuma ushobora kugera kuri 30Gbps, ari wo muvuduko ukubye gatatu ugereranyije n'umuvuduko wa WiFi 6 wa 9.6Gbps uriho ubu.
Muri make, Wi-Fi 7 yagenewe gutanga umuvuduko mwinshi cyane, ubushobozi bwo hejuru, no kohereza amakuru mu buryo budatinze cyane binyuze mu kongera umubare w'inzira zihari, ubugari bwa buri modoka itwara amakuru, n'ubugari bw'inzira igendamo.
Wi-fi 7 ifasha mu gutunganya inzira ya IoT yihuta cyane
Mu bitekerezo by'umwanditsi, ishingiro ry'ikoranabuhanga rishya rya Wi-Fi 7 si ukunoza umuvuduko wo hejuru w'igikoresho kimwe gusa, ahubwo no kwita cyane ku buryo bwo kohereza amakuru ku buryo bworoshye hakoreshejwe uburyo bwo gukoresha uburyo bwinshi (multi-lane access), nta gushidikanya ko bujyanye n'igihe cya interineti y'ibintu kiri imbere. Ubutaha, umwanditsi azavuga ku buryo bwiza cyane bwo gukoresha uburyo bwa iot:
1. Interineti y'Ibintu mu Nganda
Imwe mu mbogamizi zikomeye z’ikoranabuhanga rya iot mu nganda ni bandwidth. Uko amakuru menshi ashobora gutangwa icyarimwe, ni ko Iot izaba yihuta kandi ikora neza. Mu gihe cyo kugenzura ubuziranenge muri interineti y’inganda, umuvuduko w’umuyoboro ni ingenzi kugira ngo porogaramu zikoreshwe mu gihe nyacyo zigerweho. Hakoreshejwe umuyoboro wa Ioot wihuta cyane, ubutumwa butangwa mu gihe nyacyo bushobora koherezwa ku gihe kugira ngo habeho igisubizo cyihuse ku bibazo nk’imashini zangiritse mu buryo butunguranye n’ibindi bibazo, bikongera cyane umusaruro n’imikorere myiza y’ibigo by’inganda no kugabanya ikiguzi kidakenewe.
2. Interineti ya Edge
Kubera ko abantu basaba ko imashini zikoresha ubwenge zisubiza vuba kandi umutekano w’amakuru ya interineti y’ibintu urushaho kwiyongera, mudasobwa ikoresha ikoranabuhanga ryo mu bicu izahora iteshwa agaciro mu gihe kizaza. Edge computing yerekeza gusa ku gukoresha mudasobwa ku ruhande rw’umukoresha, bidasaba gusa imbaraga nyinshi ku ruhande rw’umukoresha, ahubwo bisaba n’umuvuduko uhagije wo kohereza amakuru ku ruhande rw’umukoresha.
3. AR/VR inyura mu buryo bwimbitse
VR ikoresha ikoranabuhanga rigezweho igomba gutanga igisubizo cyihuse gihuye n'ibikorwa by'abakinnyi mu gihe nyacyo, ibyo bikaba bisaba gutinda cyane k'umuyoboro. Niba uhora uha abakinnyi igisubizo gito, icyo gihe kwinjizwa ni ikinyoma. Wi-fi 7 yitezweho gukemura iki kibazo no kwihutisha ikoreshwa rya AR/VR ikoresha ikoranabuhanga rigezweho.
4. Umutekano w'ubwenge
Uko umutekano w’ubwenge ugenda utera imbere, ifoto yoherezwa na kamera zikoresha ubwenge igenda irushaho kuba nziza, bivuze ko amakuru ahindagurika yoherezwa agenda arushaho kuba menshi, kandi ibisabwa kugira ngo umuvuduko wa interineti n’umuyoboro w’itumanaho bikomeze kwiyongera. Kuri LAN, WIFI 7 ni yo mahitamo meza.
Ku iherezo
Wi-fi 7 ni nziza, ariko muri iki gihe, ibihugu bigaragaza imyumvire itandukanye ku bijyanye no kwemera ko WiFi ikoreshwa muri 6GHz (5925-7125mhz) nk'umuyoboro udafite uruhushya. Igihugu ntikiratanga politiki isobanutse kuri 6GHz, ariko nubwo haba hari umuyoboro wa 5GHz gusa, Wi-Fi 7 ishobora gutanga igipimo ntarengwa cyo kohereza amakuru cya 4.3Gbps, mu gihe Wi-Fi 6 ishyigikira umuvuduko wo gukuramo amakuru wa 3Gbps gusa iyo umuyoboro wa 6GHz uhari. Kubwibyo, byitezwe ko Wi-Fi 7 izagira uruhare runini mu gukoresha Lans yihuta cyane mu gihe kizaza, bigafasha ibikoresho byinshi by'ikoranabuhanga kwirinda gufatwa n'insinga.
