I-Wi-fi 6E iwumngcele omusha wobuchwepheshe be-Wi-Fi 6. I-“E” imele ukuthi “Inwetshiwe,” yengeza ibhendi entsha ye-6GHz kumabhendi okuqala angu-2.4ghz nawe-5Ghz. Ngekota yokuqala ka-2020, i-Broadcom ikhiphe imiphumela yokuhlolwa yokuqala ye-Wi-Fi 6E futhi yakhipha i-chipset yokuqala ye-wi-fi 6E ye-BCM4389. NgoMeyi 29, i-Qualcomm yamemezela i-chip ye-Wi-Fi 6E esekela amarutha namafoni.
I-Wi-fi Fi6 ibhekisela esizukulwaneni sesithupha sobuchwepheshe benethiwekhi engenantambo, enesivinini esisheshayo esiphindwe izikhathi ezingu-1.4 uma kuqhathaniswa nesizukulwane sesi-5. Okwesibili, ukuqanjwa kabusha kwezobuchwepheshe, ukusetshenziswa kobuchwepheshe be-OFDM orthogonal Frequency division multiplexing kanye nobuchwepheshe be-MU-MIMO, kwenza i-Wi-Fi 6 inikeze ulwazi oluzinzile lokuxhumanisa inethiwekhi kumadivayisi ngisho nasezimeni zokuxhuma amadivaysi amaningi futhi igcine ukusebenza kwenethiwekhi okushelelayo.
Amasignali angenantambo adluliselwa ngaphakathi kwe-spectrum engagunyaziwe ebekwe ngumthetho. Izizukulwane ezintathu zokuqala zobuchwepheshe obungenawaya, i-WiFi 4, i-WiFi 5 ne-WiFi 6, zisebenzisa amabhendi esignali amabili, njengoba kukhonjisiwe emfanekisweni ongezansi. Enye ibhendi ye-2.4ghz, esengozini yokuphazamiseka kusuka kumadivayisi amaningi, okuhlanganisa amamonitha ezingane namahhavini ama-microwave. Enye, ibhendi ye-5GHz, manje isiminyaniswe ngamadivayisi endabuko e-Wi-Fi namanethiwekhi.
Indlela yokonga amandla i-TWT (TargetWakeTime) eyethulwe iphrothokholi ye-WiFi 6 802.11ax inokuguquguquka okukhulu, ivumela imijikelezo emide yokonga amandla, kanye neshejuli yokulala yamadivayisi amaningi. Ngokuvamile, inezinzuzo ezilandelayo:
1. I-AP ixoxisana nedivayisi futhi ichaze isikhathi esithile sokufinyelela kwabezindaba.
2. Yehlisa ukungaboni ngaso linye kanye nokunqwabelana phakathi kwamakhasimende;
3. Khulisa ngokuphawulekayo isikhathi sokulala sedivayisi ukuze unciphise ukusetshenziswa kwamandla.
Isimo sohlelo lokusebenza lwe-Wi-Fi 6 siyefana naleso se-5G. Ifanele isivinini esikhulu, umthamo omkhulu, nezimo zokungabambezeleki okuphansi, okuhlanganisa nezimo zabathengi ezifana namafoni ahlakaniphile, amaphilisi, amatheminali amasha ahlakaniphile njengamakhaya ahlakaniphile, izinhlelo zokusebenza zokuchaza okuphakeme kakhulu, kanye ne-VR/AR. Izimo zesevisi ezifana nokunakekelwa kwezokwelapha okukude kwe-3D; Izigcawu eziminyana kakhulu njengezikhumulo zezindiza, amahhotela, izindawo ezinkulu, njll. Izimo zezimboni ezifana nezimboni ezihlakaniphile, izindawo zokugcina izimpahla ezingenamuntu, njll.
Idizayinelwe umhlaba lapho yonke into ixhumeke khona, i-Wi-Fi 6 inyusa kakhulu umthamo wokudlulisela kanye nesivinini ngokuthatha izilinganiso zokuxhumanisa phezulu neziphansi ezilinganayo. Ngokombiko we-Wi-Fi Alliance, inani lezomnotho emhlabeni jikelele le-WiFi lalingamadola ayizigidi eziyizinkulungwane eziyi-19.6 ngo-2018, futhi kulinganiselwa ukuthi inani lezomnotho lemboni yomhlaba wonke le-WiFi lizofinyelela ku-34.7 trillion US dollar ngo-2023.
Ingxenye yamabhizinisi emakethe ye-WLAN ikhule kakhulu ngo-q2 2021, ikhula ngamaphesenti angama-22.4 unyaka nonyaka yafinyelela ku-$1.7 billion, ngokombiko wekota wokulandela umkhondo wekota we-IDC we-Wireless Local Area Networks (WLAN). Esigabeni sabathengi semakethe ye-WLAN, imali engenayo yehle ngo-5.7% ngekota yaya ku-$2.3 billion, okuholele ekwenyukeni konyaka nonyaka ngo-4.6% kwisamba semali engenayo ngo-q2 2021.
Phakathi kwayo, imikhiqizo ye-Wi-Fi 6 iqhubekile nokukhula emakethe yabathengi, ibalwa kumaphesenti angama-24.5 wesamba semali engenayo yomkhakha wabathengi, isuka kumaphesenti angama-20.3 ngekota yokuqala ka-2021. Izindawo zokufinyelela ze-WiFi 5 zisabalwa ingxenye enkulu yemali engenayo (64.1) %) kanye nokuthunyelwa kweyunithi (64.0%).
I-Wi-fi 6 isivele inamandla, kodwa ngokusabalala kwezindlu ezihlakaniphile, inani lamadivayisi asekhaya axhumeka kumakhalekhukhwini likhula ngendlela emangalisayo, okuzodala ukuminyana ngokweqile kumabhendi angu-2.4ghz kanye ne-5GHz, okwenza kube nzima ku-Wi- Fi ukuze ifinyelele amandla ayo aphelele.
Isibikezelo se-IDC sosayizi woxhumo lwe-inthanethi Yezinto e-China eminyakeni emihlanu sibonisa ukuthi ukuxhumeka okunezintambo kanye ne-akhawunti ye-WiFi ingxenye ephezulu kakhulu yazo zonke izinhlobo zokuxhuma. Isibalo sokuxhunywa kwezintambo kanye ne-WiFi sifinyelele ezigidigidini ezingu-2.49 ngo-2020, okubalelwa kumaphesenti angu-55.1 engqikithi, futhi kulindeleke ukuthi sifinyelele ezigidigidini ezingu-4.68 ngo-2025. Ekugadisweni kwevidiyo, i-industrial iot, i-smart home nezinye izimo eziningi, izintambo kanye ne-WiFi isazoqhubeka. dlala indima ebalulekile. Ngakho-ke, ukukhuthazwa nokusetshenziswa kwe-WiFi 6E kuyadingeka kakhulu.
Ibhendi entsha ye-6Ghz ayisebenzi, ihlinzeka nge-spectrum eyengeziwe. Isibonelo, umgwaqo owaziwayo ungahlukaniswa ube yimizila emi-4, imizila engu-6, imizila engu-8, njll., futhi i-spectrum ifana "nomzila" osetshenziselwa ukudluliswa kwesignali. Izinsiza eziningi ze-spectrum zisho "imizila" eminingi, futhi ukusebenza kahle kokudlulisela kuzothuthukiswa ngokufanele.
Ngesikhathi esifanayo, ibhendi ye-6GHz yengezwa, efana ne-viaduct phezu komgwaqo osuvele ugcwele abantu, okwenza konke ukusebenza kahle komgwaqo kuthuthuke nakakhulu. Ngakho-ke, ngemva kokwethulwa kwebhendi ye-6GHz, amasu ahlukahlukene okuphatha ama-spectrum e-Wi-Fi 6 angasetshenziswa ngokuphumelelayo nangokuphelele, futhi ukusebenza kahle kokuxhumana kuphakeme, ngaleyo ndlela kunikeze ukusebenza okuphezulu, ukuphuma okukhulu kanye nokubambezeleka okuphansi.
Ezingeni lesicelo, i-WiFi 6E ixazulula kahle inkinga yokuminyana ngokweqile kumabhendi angu-2.4ghz kanye ne-5GHz. Phela, ayanda amadivaysi angenawaya ekhaya manje. Nge-6GHz, amadivayisi adinga i-inthanethi angaxhumeka kule bhendi, futhi nge-2.4ghz ne-5GHz, amandla amakhulu e-WiFi angabonakala.
Akugcini lapho, kodwa i-WiFi 6E iphinde ibe nokukhushulwa okukhulu ku-chip yocingo, enenani eliphakeme elingu-3.6Gbps, elingaphezu kokuphindwe kabili kwe-chip ye-WiFi 6. Ngaphezu kwalokho, i-WiFi 6E inokubambezeleka okuphansi okungaphansi kwama-millisecond angu-3, okungaphansi izikhathi ezingaphezu kwezingu-8 kunesizukulwane sangaphambilini endaweni eminyene. Inganikeza ulwazi olungcono kumageyimu, ividiyo eneNCAZELO EPHEZULU, izwi nezinye izici.
