I-Wi-fi 6E yindawo entsha yobuchwepheshe be-Wi-Fi 6. Igama elithi “E” limele igama elithi “Extended,” longeza ibhendi entsha ye-6GHz kwiibhendi zokuqala ze-2.4ghz kunye ne-5Ghz. Kwikota yokuqala ka-2020, iBroadcom ikhuphe iziphumo zokuqala zovavanyo lwe-Wi-Fi 6E kwaye ikhuphe i-chipset yokuqala ye-wi-fi 6E ye-BCM4389 kwihlabathi liphela. Ngomhla wama-29 kuMeyi, iQualcomm ibhengeze itshiphu ye-Wi-Fi 6E exhasa ii-routers kunye neefowuni.
I-Wi-fi Fi6 ibhekisa kwisizukulwana sesi-6 sobuchwepheshe benethiwekhi engenazingcingo, obunesantya soqhagamshelo lwe-intanethi esiphindwe ka-1.4 xa kuthelekiswa nesizukulwana sesi-5. Okwesibini, ukuveliswa kweteknoloji, ukusetyenziswa kwetekhnoloji ye-OFDM orthogonal Frequency division multiplexing kunye netekhnoloji ye-MU-MIMO, kwenza i-Wi-Fi 6 ikwazi ukubonelela ngamava oqhagamshelo lwenethiwekhi oluzinzileyo kwizixhobo nakwiimeko zoqhagamshelo lwezixhobo ezininzi kwaye igcine ukusebenza kwenethiwekhi okugudileyo.
Imiqondiso engenazingcingo idluliselwa ngaphakathi kwe-spectrum echaziweyo engenalayisenisi echazwe ngumthetho. Izizukulwana ezintathu zokuqala zetekhnoloji engenazingcingo, iWiFi 4, iWiFi 5 kunye neWiFi 6, zisebenzisa iibhendi ezimbini zesignali, njengoko kubonisiwe kumfanekiso ongezantsi. Enye yibhendi ye-2.4ghz, esengozini yokuphazamiseka yizixhobo ezininzi, kubandakanya iimonitha zomntwana kunye nee-oveni ze-microwave. Enye, ibhendi ye-5GHz, ngoku ixinene zizixhobo zeWi-Fi zemveli kunye neenethiwekhi.
Indlela yokonga umbane i-TWT (TargetWakeTime) eyaziswa yi-WiFi 6 protocol 802.11ax inokuguquguquka okukhulu, ivumela imijikelo yokonga umbane emide, kunye nokucwangciswa kokulala kwezixhobo ezininzi. Ngokubanzi, inezi nzuzo zilandelayo:
1. I-AP ithethathethana nesixhobo ize ichaze ixesha elithile lokufikelela kwimidiya.
2. Nciphisa iingxabano kunye nokudibana phakathi kwabathengi;
3. Yandisa kakhulu ixesha lokulala kwesixhobo ukuze kuncitshiswe ukusetyenziswa kwamandla.
Imeko yokusetyenziswa kwe-Wi-Fi 6 ifana ne-5G. Ifanelekile kwiimeko zesantya esiphezulu, umthamo omkhulu, kunye neemeko ze-latency ephantsi, kubandakanya iimeko zabathengi ezifana neefowuni ezihlakaniphile, iithebhulethi, ii-terminals ezintsha ezihlakaniphile ezifana nezindlu ezihlakaniphile, usetyenziso oluphezulu kakhulu, kunye ne-VR/AR. Imeko zenkonzo ezifana nonyango olukude lwe-3D; Iindawo ezinoxinano olukhulu ezifana nezikhululo zeenqwelo-moya, iihotele, iindawo ezinkulu, njl. Imeko zezinga lemizi-mveliso ezifana neefektri ezihlakaniphile, iindawo zokugcina impahla ezingenabantu, njl.
Yenzelwe ihlabathi apho yonke into iqhagamshelwe khona, i-Wi-Fi 6 yonyusa kakhulu amandla othumelo kunye nesantya ngokuthatha amazinga okunyuka kunye nokwehla. Ngokwengxelo ye-Wi-Fi Alliance, ixabiso lezoqoqosho le-WiFi kwihlabathi liphela laliyi-19.6 trillion yeedola zaseMelika ngo-2018, kwaye kuqikelelwa ukuba ixabiso lezoqoqosho lwe-WiFi kwihlabathi liphela liza kufikelela kwi-34.7 trillion yeedola zaseMelika ngo-2023.
Icandelo leshishini lemarike ye-WLAN likhule kakhulu kwikota yesibini ka-2021, likhula ngama-22.4 ekhulwini ngonyaka ukuya kwi-$1.7 yezigidigidi, ngokutsho kwengxelo yokulandelela yekota ye-IDC ye-Wireless Local Area Networks (WLAN). Kwicandelo labathengi kwimarike ye-WLAN, ingeniso yehle nge-5.7% kwikota ukuya kwi-$2.3 yezigidigidi, nto leyo ekhokelele ekunyukeni kwe-4.6% ngonyaka kwingeniso iyonke kwikota yesibini ka-2021.
Phakathi kwazo, iimveliso ze-Wi-Fi 6 ziqhubekile nokukhula kwimarike yabathengi, zibanga i-24.5 yepesenti yengeniso iyonke kwicandelo labathengi, ukusuka kwi-20.3 yepesenti kwikota yokuqala ka-2021. Iindawo zokufikelela ze-WiFi 5 zisabanga uninzi lwengeniso (64.1%) kunye nokuthunyelwa kweyunithi (64.0%).
I-Wi-fi 6 sele inamandla, kodwa ngokusasazeka kwezindlu ezikrelekrele, inani lezixhobo ezisekhaya eziqhagamshela kwi-wireless liyanda kakhulu, nto leyo eya kubangela ukuxinana okukhulu kwiibhendi ze-2.4ghz kunye ne-5GHz, nto leyo eyenza kube nzima kwi-Wi-Fi ukufikelela kwisakhono sayo esipheleleyo.
Uqikelelo lwe-IDC lobukhulu boqhagamshelo lwe-Intanethi yezinto eTshayina kwiminyaka emihlanu lubonisa ukuba uqhagamshelo olunezintambo kunye ne-WiFi zibangela inani eliphezulu lazo zonke iintlobo zoqhagamshelo. Inani loqhagamshelo olunezintambo kunye ne-WiFi lifikelele kwi-2.49 yeebhiliyoni ngo-2020, lifikelela kwi-55.1 yeepesenti iyonke, kwaye kulindeleke ukuba lifikelele kwi-4.68 yeebhiliyoni ngo-2025. Kwividiyo yokujonga, i-iot yemizi-mveliso, ikhaya elikrelekrele kunye nezinye iimeko ezininzi, i-wired kunye ne-WiFi ziya kusadlala indima ebalulekileyo. Ke ngoko, ukukhuthazwa nokusetyenziswa kwe-WiFi 6E kubaluleke kakhulu.
Ibhendi entsha ye-6Ghz ayisebenzi kangako, inika i-spectrum engaphezulu. Umzekelo, indlela eyaziwayo inokwahlulwa ibe ziindlela ezi-4, iindlela ezi-6, iindlela ezi-8, njl.njl., kwaye i-spectrum ifana "nendlela" esetyenziselwa ukudlulisa isignali. Izixhobo ze-spectrum ezingaphezulu zithetha "iindlela" ezingaphezulu, kwaye ukusebenza kakuhle kokudlulisa kuya kuphuculwa ngokufanelekileyo.
Kwangaxeshanye, kongezwa ibhendi ye-6GHz, efana ne-viaduct phezu kwendlela esele ixinene, nto leyo eyenza ukuba ukusebenza kakuhle kothutho lwendlela kuphucuke ngakumbi. Ke ngoko, emva kokungeniswa kwebhendi ye-6GHz, amaqhinga ahlukeneyo olawulo lwe-spectrum ye-Wi-Fi 6 anokusetyenziswa ngokufanelekileyo nangokupheleleyo, kwaye ukusebenza kakuhle konxibelelwano kuphezulu, ngaloo ndlela kubonelela ngokusebenza okuphezulu, ukuphumelela okukhulu kunye nokubambezeleka okuphantsi.
Kwinqanaba lesicelo, iWiFi 6E isombulula kakuhle ingxaki yokuxinana okukhulu kwiibhendi ze-2.4ghz kunye ne-5GHz. Kaloku, kukho izixhobo ezingenazingcingo ezininzi ngakumbi ekhaya ngoku. Nge-6GHz, izixhobo ezifuna i-intanethi zinokuqhagamshela kweli bhendi, kwaye nge-2.4ghz kunye ne-5GHz, amandla aphezulu eWiFi anokufezekiswa.
Ayipheleli apho, kodwa iWiFi 6E ikwanokunyusa okukhulu kwitshiphu yefowuni, ngesantya esiphezulu se-3.6Gbps, ngaphezulu kwesibini kunesetshiphu yeWiFi 6. Ukongeza, iWiFi 6E inexesha eliphantsi lokulibaziseka elingaphantsi kwe-3 milliseconds, elingaphantsi ngokuphindwe kasibhozo kunesizukulwana sangaphambili kwindawo exineneyo. Ingabonelela ngamava angcono kwimidlalo, ividiyo ye-HIGH-DEFINITION, ilizwi kunye nezinye izinto.
