I-Wi-fi 6E iwumngcele omusha wobuchwepheshe be-Wi-Fi 6. I-“E” imele ukuthi “Extended,” enezela ibhendi entsha ye-6GHz kumabhendi okuqala angu-2.4ghz kanye no-5Ghz. Kwikota yokuqala ka-2020, i-Broadcom ikhiphe imiphumela yokuqala yokuhlola ye-Wi-Fi 6E futhi yakhipha i-chipset yokuqala ye-wi-fi 6E emhlabeni i-BCM4389. Ngomhlaka-29 Meyi, i-Qualcomm yamemezela i-chip ye-Wi-Fi 6E esekela ama-router namafoni.
I-Wi-fi Fi6 ibhekisela esizukulwaneni sesi-6 sobuchwepheshe benethiwekhi engenantambo, obunesivinini sokuxhumeka kwe-inthanethi esisheshayo ngokuphindwe ka-1.4 uma kuqhathaniswa nesizukulwane sesi-5. Okwesibili, ukusungula izinto ezintsha kwezobuchwepheshe, ukusetshenziswa kobuchwepheshe be-OFDM orthogonal Frequency division multiplexing kanye nobuchwepheshe be-MU-MIMO, kwenza i-Wi-Fi 6 ikwazi ukunikeza ulwazi oluzinzile lokuxhumeka kwenethiwekhi kumadivayisi ngisho nasezimweni zokuxhumeka kwamadivayisi amaningi futhi igcine ukusebenza kwenethiwekhi okubushelelezi.
Izimpawu ezingenantambo zidluliselwa ngaphakathi kwe-spectrum engagunyaziwe echazwe ngumthetho. Izizukulwane ezintathu zokuqala zobuchwepheshe ezingenantambo, i-WiFi 4, i-WiFi 5 kanye ne-WiFi 6, zisebenzisa amabhendi amabili esignali, njengoba kuboniswe esithombeni esingezansi. Esinye yibhendi engu-2.4ghz, esengozini yokuphazamiseka okuvela kumadivayisi amaningi, kufaka phakathi ama-baby monitors nama-microwave ovens. Esinye, ibhendi engu-5GHz, manje isivalwe amadivayisi namanethiwekhi e-Wi-Fi avamile.
Indlela yokonga amandla i-TWT (TargetWakeTime) eyethulwe yiphrothokholi ye-WiFi 6 802.11ax inokuguquguquka okukhulu, ivumela imijikelezo ende yokonga amandla, kanye nokuhlela ukulala kwamadivayisi amaningi. Ngokuvamile, inezinzuzo ezilandelayo:
1. I-AP ixoxisana nedivayisi bese ichaza isikhathi esithile sokufinyelela abezindaba.
2. Nciphisa ukungezwani kanye nokufana phakathi kwamakhasimende;
3. Khulisa kakhulu isikhathi sokulala sedivayisi ukuze unciphise ukusetshenziswa kwamandla.
Isimo sohlelo lokusebenza lwe-Wi-Fi 6 sifana nese-5G. Sifanele izimo zesivinini esiphezulu, umthamo omkhulu, kanye nokubambezeleka okuphansi, okuhlanganisa izimo zabathengi ezifana namafoni ahlakaniphile, amathebhulethi, amatheminali amasha ahlakaniphile njengezindlu ezihlakaniphile, izinhlelo zokusebenza ezichaza kakhulu, kanye ne-VR/AR. Izimo zesevisi ezifana nokunakekelwa kwezokwelapha okukude kwe-3D; Izimo zabantu abaningi njengezindiza, amahhotela, izindawo ezinkulu, njll. Izimo zezinga lezimboni ezifana nezimboni ezihlakaniphile, izindawo zokugcina impahla ezingenabantu, njll.
Idizayinelwe umhlaba lapho konke kuxhunyiwe khona, i-Wi-Fi 6 ikhulisa kakhulu umthamo wokudlulisa kanye nesivinini ngokuthatha amazinga okuxhumanisa alinganayo kanye nokuxhumanisa. Ngokusho kombiko we-Wi-Fi Alliance, inani lezomnotho lomhlaba wonke le-WiFi lalingamadola ayizigidigidi eziyi-19.6 zaseMelika ngo-2018, futhi kulinganiselwa ukuthi inani lezomnotho wezimboni zomhlaba wonke le-WiFi lizofinyelela kumadola ayizigidigidi ezingama-34.7 zaseMelika ngo-2023.
Ingxenye yebhizinisi yemakethe ye-WLAN ikhule kakhulu ngekota yesibili ka-2021, ikhula ngamaphesenti angama-22.4 ngonyaka yafinyelela ku-$1.7 billion, ngokusho kombiko wokulandelela wekota we-IDC we-Wireless Local Area Networks (WLAN). Engxenyeni yabathengi yemakethe ye-WLAN, imali engenayo yehle ngo-5.7% ngekota yafinyelela ku-$2.3 billion, okwaholela ekukhuleni okungu-4.6% ngonyaka ngonyaka kwenzuzo iyonke ngekota yesibili ka-2021.
Phakathi kwazo, imikhiqizo ye-Wi-Fi 6 iqhubekile nokukhula emakethe yabathengi, ibiza amaphesenti angama-24.5 emali engenayo iyonke emkhakheni wabathengi, isuka kumaphesenti angama-20.3 kwikota yokuqala ka-2021. Izindawo zokufinyelela ze-WiFi 5 zisabiza iningi lemali engenayo (64.1%) kanye nokuthunyelwa kweyunithi (64.0%).
I-Wi-fi 6 isivele inamandla, kodwa ngokusabalala kwezindlu ezihlakaniphile, inani lamadivayisi ekhaya axhumeka ku-wireless liyanda kakhulu, okuzobangela ukuminyana okukhulu kuma-band angu-2.4ghz kanye no-5GHz, okwenza kube nzima nge-Wi-Fi ukufinyelela amandla ayo aphelele.
Isibikezelo se-IDC sobukhulu bokuxhumeka kwe-Intanethi Yezinto eShayina eminyakeni emihlanu sibonisa ukuthi ukuxhumeka okunezintambo kanye ne-WiFi kubalwa ingxenye ephezulu kakhulu yazo zonke izinhlobo zokuxhumeka. Inani lokuxhumeka okunezintambo kanye ne-WiFi lifinyelele ku-2.49 billion ngo-2020, okubalwa amaphesenti angu-55.1 esamba, futhi kulindeleke ukuthi lifinyelele ku-4.68 billion ngo-2025. Ekuhlolweni kwevidiyo, i-iot yezimboni, ikhaya elihlakaniphile kanye nezinye izimo eziningi, i-wired kanye ne-WiFi kusazodlala indima ebalulekile. Ngakho-ke, ukukhuthazwa kanye nokusetshenziswa kwe-WiFi 6E kuyadingeka kakhulu.
Ibhendi entsha ye-6Ghz ayisebenzi kahle, inikeza i-spectrum eyengeziwe. Isibonelo, umgwaqo owaziwayo ungahlukaniswa ube yimizila emi-4, imizila emi-6, imizila eyi-8, njll., futhi i-spectrum ifana “nemizila” esetshenziselwa ukudlulisa isignali. Izinsizakusebenza ze-spectrum ezengeziwe zisho “imizila” eminingi, futhi ukusebenza kahle kokudlulisa kuzothuthukiswa ngokufanele.
Ngesikhathi esifanayo, kufakwe ibhendi ye-6GHz, efana ne-viaduct phezu komgwaqo osuvele ugcwele, okwenza ukusebenza kahle kwezokuthutha komgwaqo kuthuthuke kakhulu. Ngakho-ke, ngemuva kokwethulwa kwebhendi ye-6GHz, amasu ahlukahlukene okuphatha i-spectrum ye-Wi-Fi 6 angasetshenziswa ngempumelelo nangokuphelele, futhi ukusebenza kahle kokuxhumana kuphakeme, ngaleyo ndlela kuhlinzeke ukusebenza okuphezulu, ukudlula okukhulu kanye nokubambezeleka okuphansi.
Ezingeni lesicelo, i-WiFi 6E ixazulula kahle inkinga yokuminyana ngokweqile kuma-band angu-2.4ghz kanye no-5GHz. Phela, kunamadivayisi amaningi angenantambo ekhaya manje. Nge-6GHz, amadivayisi adinga i-inthanethi angaxhuma kule bhendi, futhi nge-2.4ghz kanye no-5GHz, amandla aphezulu e-WiFi angabonakala.
Akukhona lokho kuphela, kodwa ne-WiFi 6E nayo inamandla amakhulu kwi-chip yocingo, ngesilinganiso esiphezulu esingu-3.6Gbps, okuphindwe kabili kune-chip ye-WiFi 6. Ngaphezu kwalokho, i-WiFi 6E inokulibaziseka okuphansi okungaphansi kwama-millisecond amathathu, okungaphezu kokuphindwe kasishiyagalombili kunesizukulwane esidlule endaweni exinene. Inganikeza ulwazi olungcono emidlalweni, ividiyo enencazelo ephezulu, izwi nezinye izici.
