Wi-fi 6E ni umupaka mushya w’ikoranabuhanga rya Wi-Fi 6. “E” isobanura “Extended,” yongeraho umugozi mushya wa 6GHz ku mugozi wa 2.4ghz na 5Ghz wa mbere. Mu gihembwe cya mbere cya 2020, Broadcom yasohoye ibyavuye mu igeragezwa rya mbere rya Wi-Fi 6E inashyira ahagaragara chipset ya mbere ku isi ya wi-fi 6E BCM4389. Ku ya 29 Gicurasi, Qualcomm yatangaje chip ya Wi-Fi 6E ishyigikira routers na terefone.
Wi-fi Fi6 yerekeza ku ikoranabuhanga rya interineti rikoresha insinga ku gisekuru cya 6, rifite umuvuduko wihuta inshuro 1.4 ugereranije n’irya 5. Icya kabiri, udushya mu ikoranabuhanga, ikoreshwa ry’ikoranabuhanga rya OFDM orthogonal Frequency division multiplexing na MU-MIMO technology, bituma Wi-Fi 6 itanga uburyo bwo guhuza interineti buhamye ku bikoresho ndetse no mu bihe byo guhuza ibikoresho byinshi no gukomeza gukora neza kw’itumanaho.
Ibimenyetso bidakoresha insinga byoherezwa mu buryo buteganywa n'amategeko. Ibisekuru bitatu bya mbere by'ikoranabuhanga ridakoresha insinga, WiFi 4, WiFi 5 na WiFi 6, bikoresha imirongo ibiri y'ibimenyetso, nk'uko bigaragara ku ishusho iri hepfo. Imwe ni umugozi wa 2.4ghz, ushobora kwibasirwa n'ibikoresho byinshi, birimo moniteur z'abana n'amashyiga ya mikoroonde. Indi, umugozi wa 5GHz, ubu ugizwe n'ibikoresho n'imiyoboro gakondo ya Wi-Fi.
Uburyo bwo kuzigama amashanyarazi bwa TWT (TargetWakeTime) bwashyizweho na protocole ya WiFi 6 802.11ax bufite ubushobozi bwo koroshya ibintu, butuma habaho kuzigama amashanyarazi igihe kirekire, ndetse no guteganya igihe cyo gusinzira hakoreshejwe ibikoresho byinshi. Muri rusange, bufite ibyiza bikurikira:
1. AP iganira n'igikoresho kandi ikagena igihe cyihariye cyo kwinjira mu itangazamakuru.
2. Kugabanya amakimbirane n'imikoranire hagati y'abakiriya;
3. Ongera cyane igihe cyo gusinzira cy'igikoresho kugira ngo ugabanye ikoreshwa ry'ingufu.
Uburyo Wi-Fi 6 ikoreshwa busa n’ubwa 5G. Ikwiriye gukoresha umuvuduko mwinshi, ubushobozi bunini, n’uburyo bwo gutinda guke, harimo n’uburyo abaguzi bakoresha nka telefoni zigezweho, tableti, ibyuma bishya bigezweho nka za smart homes, porogaramu zigezweho cyane, na VR/AR. Uburyo serivisi zitangwa nko kwita ku buzima bwa kure bwa 3D; Ahantu hagaragara abantu benshi nko ku bibuga by’indege, amahoteli, ahantu hanini ho gukorera, nibindi. Uburyo bwo gukora ku rwego rw’inganda nka za smart hotels, ububiko butagira abakoresha, nibindi.
Yagenewe isi aho byose bihujwe, Wi-Fi 6 yongera cyane ubushobozi bwo kohereza ubutumwa n'umuvuduko binyuze mu gufata igipimo cy'imiyoboro ihuza itumanaho n'imiyoboro ihuza itumanaho. Nk'uko raporo ya Wi-Fi Alliance ibivuga, agaciro k'ubukungu bwa Wi-Fi ku isi kari tiriyari 19.6 z'amadolari y'Amerika mu 2018, kandi bivugwa ko agaciro k'ubukungu bw'inganda ku isi ka Wi-Fi kazagera kuri tiriyari 34.7 z'amadolari y'Amerika mu 2023.
Raporo y’ikurikirana ry’igihembwe cya buri kwezi ya IDC ku bijyanye n’abaguzi ba WLAN ku isi (Wireless Local Area Networks - WLAN) igaragaza igice cy’ibigo by’ubucuruzi byazamutse cyane mu gihembwe cya kabiri cya 2021, kizamukaho 22.4% ugereranyije n’umwaka ushize kigera kuri miliyari 1.7 z’amadolari y’Amerika. Mu gice cy’abaguzi ku isoko rya WLAN, inyungu zagabanutseho 5.7% muri iki gihembwe zigera kuri miliyari 2.3 z’amadolari y’Amerika, bituma inyungu zose ziyongeraho 4.6% ugereranyije n’umwaka ushize mu gihembwe cya kabiri cya 2021.
Muri byo, ibicuruzwa bya Wi-Fi 6 byakomeje kwiyongera ku isoko ry’abaguzi, bingana na 24.5% by’amafaranga yose yinjira mu rwego rw’abaguzi, biturutse kuri 20.3% mu gihembwe cya mbere cya 2021. Aho itumanaho rya Wi-Fi 5 ryakomeje kuba irya mbere mu kwinjiza amafaranga menshi (64.1%) n’ayoherezwa mu buryo buciriritse (64.0%).
Wi-fi 6 isanzwe ifite imbaraga, ariko bitewe n’ikwirakwira ry’amazu akoresha insinga, umubare w’ibikoresho mu rugo bihuza n’insinga uri kwiyongera cyane, ibi bikazatera ubucucike bukabije mu miyoboro ya 2.4ghz na 5GHz, bigatuma Wi-Fi idashobora kugera ku bushobozi bwayo bwose.
IDC yahanuye ko ingano y'itumanaho rya interineti y'ibintu mu Bushinwa mu myaka itanu ishize igaragaza ko itumanaho ry'insinga na WiFi ari byo bifite umubare munini w'itumanaho ry'ubwoko bwose. Umubare w'itumanaho ry'insinga na WiFi wageze kuri miliyari 2.49 mu 2020, bingana na 55.1 ku ijana by'ikoreshwa ryose, kandi biteganijwe ko uzagera kuri miliyari 4.68 mu 2025. Mu kugenzura amashusho, ikoreshwa ry'inganda, ikoranabuhanga mu rugo n'ibindi byinshi, itumanaho ry'insinga na WiFi bizakomeza kugira uruhare runini. Kubwibyo, kwamamaza no gukoresha WiFi 6E ni ngombwa cyane.
Umuyoboro mushya wa 6Ghz ntukora cyane, utanga spectrum nyinshi. Urugero, umuhanda uzwi cyane ushobora kugabanywamo imirongo 4, imirongo 6, imirongo 8, nibindi, kandi spectrum imeze nk'"inzira" ikoreshwa mu kohereza ibimenyetso. Ingufu nyinshi za spectrum bivuze "inzira" nyinshi, kandi imikorere myiza ya terminal izarushaho kunozwa uko bikwiye.
Muri icyo gihe, hongeweho umugozi wa 6GHz, umeze nk'inzira inyura hejuru y'umuhanda usanzwe wuzuye abantu, bigatuma imikorere myiza y'ubwikorezi bw'umuhanda irushaho kunozwa. Kubwibyo, nyuma yo gushyirwaho umugozi wa 6GHz, ingamba zitandukanye zo gucunga spectrum za Wi-Fi 6 zishobora gushyirwa mu bikorwa neza kandi mu buryo bwuzuye, kandi imikorere myiza y'itumanaho ikaba iri hejuru, bityo bigatanga imikorere myiza, umusaruro mwinshi no kugabanuka k'umuvuduko.
Ku rwego rwo gukoresha, WiFi 6E ikemura neza ikibazo cy’ubwinshi bw’amajwi mu miyoboro ya 2.4ghz na 5GHz. N’ubundi kandi, hari ibikoresho byinshi bitagira insinga mu rugo ubu. Hamwe na 6GHz, ibikoresho bisaba interineti bishobora guhuzwa n’iyi miyoboro, kandi hamwe na 2.4ghz na 5GHz, ubushobozi ntarengwa bwa WiFi burashobora kugerwaho.
Si ibyo gusa, WiFi 6E inafite ingufu nyinshi kuri chip ya telefoni, ifite umuvuduko wo hejuru wa 3.6Gbps, ikubye kabiri ugereranyije na chip ya WiFi 6. Byongeye kandi, WiFi 6E ifite gutinda guto munsi ya milisegonda 3, bikubye inshuro zirenga umunani ugereranyije n’izabanjirije iyi mu bidukikije bicucitse. Ishobora gutanga ubunararibonye bwiza mu mikino, videwo isobanutse neza, ijwi n’ibindi bintu.
