Ekuthuthukisweni kwayo, i-Huawei incike ku-Wi-Fi 6. Futhi imibuzo evela kozakwethu namakhasimende mayelana nesizukulwane esisha sezinga isishukumisele ukuba sibhale okuthunyelwe mayelana nezisekelo zetiyori nezimiso zomzimba ezishumekwe kuyo. Ake sisuke emlandweni siye kusayensi yemvelo futhi sibheke ngokuningiliziwe ukuthi kungani kudingeka ubuchwepheshe be-OFDMA ne-MU-MIMO. Ake siphinde sikhulume ngokuthi indlela yokudluliswa kwedatha eklanywe kabusha ngokuyisisekelo ikwenze kwaba nokwenzeka kanjani ukuzuza umthamo wesiteshi oqinisekisiwe kanye nokuncipha kwezinga lilonke lokubambezeleka okuze kwaqhathaniseka naleyo yomsebenzisi. Futhi lokhu naphezu kokuthi amanethiwekhi esimanje asekelwe ku-5G abiza kakhulu (ngokwesilinganiso izikhathi ezingu-20-30) kunamanethiwekhi e-Wi-Fi 6 angaphakathi anamakhono afanayo.
KuHuawei, isihloko asisona neze esokungenzi lutho: izixazululo ezisekela i-Wi-Fi 6 ziphakathi kwemikhiqizo yethu enempumelelo kakhulu ngo-2020, lapho kutshalwe khona izinsiza ezinkulu. Nasi isibonelo esisodwa nje: ucwaningo emkhakheni wesayensi yezinto zokwakha lusivumele ukuthi sikhethe ingxubevange, ukusetshenziswa kwayo ezicini zomsakazo zendawo yokufinyelela kukhuphule isilinganiso sesignali-kuya-nomsindo ngo-2-3 dB: izigqoko zehliselwa ku-Doron Ezri le mpumelelo.
Umlando omncane
Kunengqondo ukubala umlando we-Wi-Fi emuva ku-1971, lapho eNyuvesi yaseHawaii, uProfesa Norman Abramson kanye neqembu lozakwabo bathuthukisa, bakha futhi bethula inethiwekhi yedatha yephakethe engenantambo ye-ALOHAnet.
Ngo-1980, kwavunywa iqembu lamazinga nezivumelwano IEEE 802, echaza ukuhlelwa kwezingqimba ezimbili eziphansi zemodeli yenethiwekhi ye-OSI enezingqimba eziyisikhombisa. Kwadingeka silinde iminyaka eyi-802.11 ngaphambi kokukhishwa kwenguqulo yokuqala ye-17.
Ngokwamukelwa kwezinga le-1997 ngo-802.11, eminyakeni emibili ngaphambi kokuzalwa kwe-Wi-Fi Alliance, isizukulwane sokuqala sobuchwepheshe bedatha obungenawaya obudume kakhulu namuhla sangena emhlabeni obanzi.
Okujwayelekile kwe-IEEE 802. Izizukulwane ze-Wi-Fi
Izinga lokuqala elizosekelwa kabanzi ngempela abakhiqizi bemishini lalingu-802.11b. Njengoba ubona, imvamisa yezinto ezintsha bezinzile kusukela ekupheleni kwekhulu lama-XNUMX: izinguquko zekhwalithi zithatha isikhathi. Eminyakeni yamuva nje, mningi umsebenzi owenziwe ukuthuthukisa indlela yokudlulisa amasignali ebonakalayo. Ukuze siqonde kangcono izinkinga zesimanje ze-Wi-Fi, ake siphendukele ezisekelweni zayo ezibonakalayo.
Masikhumbule izisekelo!
Amagagasi omsakazo ayisimo esikhethekile samaza kagesi - asakazwa emthonjeni wokuphazamiseka kukagesi kanye nozibuthe. Abonakala ngemingcele emithathu eyinhloko: i-vector ye-wave, kanye nama-vectors anamandla kagesi kanye namagnetic field. Zontathu ziyi-perpendicular komunye nomunye. Kulokhu, imvamisa yegagasi ngokuvamile ibizwa ngokuthi inombolo yokuphindaphinda ama-oscillation alingana neyunithi yesikhathi.
Wonke lawa amaqiniso aziwayo. Nokho, ukuze sifinyelele ekugcineni, siphoqeleka ukuba siqale kusukela ekuqaleni.
Esikalini esivamile sobubanzi befrikhwensi yemisebe kagesi, ububanzi bomsakazo buthatha ingxenye ephansi kakhulu (yemvamisa ephansi). Ihlanganisa amagagasi kagesi ane-oscillation frequency kusuka ku-3 Hz kuya ku-3000 GHz. Wonke amanye amabhendi, okuhlanganisa ukukhanya okubonakalayo, anemvamisa ephezulu kakhulu.
Uma i-frequency iphezulu, amandla engeziwe angadluliselwa kumagagasi omsakazo, kodwa ngesikhathi esifanayo igoba izithiyo kancane futhi inciphe ngokushesha. Okuphambene nakho kuyiqiniso. Uma kubhekwa lezi zici, izigaba ezimbili zamafrikhwensi eziyinhloko zikhethelwe ukusebenza kwe-Wi-Fi - 2,4 GHz (ibhendi yefrikhwensi ukusuka ku-2,4000 ukuya ku-2,4835 GHz) kanye no-5 GHz (amabhendi amafrikhwensi 5,170-5,330, 5,490-5,730 kanye no-5,735 GHz).
Amagagasi omsakazo asakazeka kuzo zonke izinhlangothi, futhi ukuze avimbele imilayezo ukuthi ingathonya omunye komunye ngenxa yomphumela wokuphazamiseka, ibhendi yefrikhwensi ivame ukuhlukaniswa ngezigaba ezihlukene ezincane - iziteshi ezinenye noma enye. . Umdwebo ongenhla ubonisa ukuthi iziteshi eziseduze 1 no-2 ezinomkhawulokudonsa we-20 MHz zizophazamisana, kodwa u-1 no-6 ngeke.
Isignali engaphakathi kwesiteshi isakazwa kusetshenziswa igagasi lomsakazo kumaza okuthutha athile. Ukudlulisa ulwazi, amagagasi nemingcele kungaba by frequency, amplitude noma isigaba.
Ukuhlukaniswa kwesiteshi kumabanga wefrikhwensi ye-Wi-Fi
Ibanga lefrikhwensi le-2,4 GHz lihlukaniswe ngamashaneli agqagqene kancane angu-14 anobubanzi obufanele obungu-20 MHz. Kwake kukholakala ukuthi lokhu kwanele ukuhlela inethiwekhi eyinkimbinkimbi engenazintambo. Ngokushesha kwacaca ukuthi umthamo wobubanzi uphela ngokushesha, ngakho-ke uhla lwe-5 GHz lwengezwe kulo, umthamo we-spectral ophakeme kakhulu. Kuyo, ngaphezu kwamashaneli angu-20 MHz, kungenzeka ukwaba iziteshi ezinobubanzi obungu-40 no-80 MHz.
Ukuze kuthuthukiswe ukusebenza kahle kokusebenzisa i-radio frequency spectrum, ubuchwepheshe be-orthogonal frequency division multiplexing manje sebusetshenziswa kabanzi ().
Kuhilela ukusebenzisa, kanye nemvamisa yenkampani yenethiwekhi, amafrikhwensi ambalwa e-subcarrier esiteshini esifanayo, okwenza kube nokwenzeka ukuhambisa idatha efanayo. I-OFDM ikuvumela ukuthi usabalalise ithrafikhi ngendlela βeyimbudumbuduβ elula, kodwa ngenxa yeminyaka yayo ehloniphekile, igcina inani lokungalungi okubalulekile. Phakathi kwazo kunezimiso zokusebenza kusetshenziswa iphrothokholi yenethiwekhi ye-CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance), ngokuya ngokuthi umsebenzisi oyedwa kuphela ongasebenza kusithwali esisodwa kanye nenkampani yenethiwekhi ngezikhathi ezithile.
Ukugeleza kwendawo
Indlela ebalulekile yokwandisa inethiwekhi engenantambo ukusebenzisa imifudlana yendawo.
Indawo yokufinyelela iphethe amamojula omsakazo amaningana (eyodwa, amabili noma ngaphezulu), axhunywe kwinombolo ethile yezimpondo. Lawa ma-antenna asakaza ngokwephethini ethile nokuguquguquka, futhi mina nawe sithola ulwazi oludluliselwa ngocingo olungenantambo. Ukusakaza kwendawo kungakhiwa phakathi kwe-antenna ethile ebonakalayo (imojula yomsakazo) yendawo yokufinyelela kanye nedivayisi yomsebenzisi. Ngenxa yalokhu, inani eliphelele lolwazi oludluliswa kusukela endaweni yokufinyelela likhuphuka ngokuphindaphinda kwenombolo yokusakaza (izinti).
Ngokuvumelana nezindinganiso zamanje, ukusakazwa kwendawo okungafika kokune kungasetshenziswa ebhendini engu-2,4 GHz, futhi kufike ku-5 ebhendini engu-XNUMX GHz.
Ngaphambilini, lapho sisebenza kumabhendi angu-2,4 no-5 GHz, sasigxile kuphela enanini lamamojula omsakazo. Ukuba khona kwemodyuli yesibili yomsakazo kunikeze ukuguquguquka okwengeziwe, njengoba kuvumela amadivayisi amadala abhalisile ukuthi asebenze imvamisa ye-2,4 GHz, futhi amasha asebenze ngemvamisa ye-5 GHz. Ngokufika kwamamojula omsakazo wesithathu nalandelayo, kwavela ezinye izinkinga. Izinto ezikhipha imisebe zivame ukuphazamisana, okwandisa izindleko zedivayisi ngenxa yesidingo sokuklama okungcono nokuhlomisa indawo yokufinyelela ngezihlungi zesinxephezelo. Ngakho-ke kusanda kwenzeka ukusekela ngesikhathi esisodwa ukusakazwa kwendawo okungu-16 endaweni ngayinye yokufinyelela.
Ijubane elingokoqobo nelithiyori
Ngenxa yezindlela zokusebenza ze-OFDM, asikwazanga ukuthola inani eliphezulu lenethiwekhi. Izibalo zethiyori zokuqaliswa kokusebenza kwe-OFDM kwenziwa kudala futhi ngokuphathelene nezimo ezikahle kuphela, lapho isilinganiso se-signal-to-noise ephezulu kakhulu (SNR) kanye nezinga lephutha elincane (BER) bekulindeleke ngokubikezelwa. Ezimweni zesimanje zomsindo onamandla kuwo wonke ama-spectrum omsakazo esithakaselayo, ukusebenza kwamanethiwekhi asekelwe ku-OFDM kuphansi ngokucindezelayo. Futhi umthetho olandelwayo uqhubekile nokuthwala lezi ziphutha kwaze kwaba muva nje, kwaze kwaba yilapho ubuchwepheshe be-OFDMA (i-orthogonal frequency-division multiple) busiza. Mayelana naye - kancane kancane.
Ake sikhulume ngezimpondo
Njengoba wazi, i-antenna ngayinye inenzuzo, kuye ngenani lapho iphethini yendawo yokusabalalisa isignali (i-beamforming) yakhiwe ngendawo ethile yokumboza (asikunaki ukubonakaliswa kabusha kwesignali, njll.). Yilokhu kanye abaklami abahlale besekela ukucabanga kwabo kokuthi izindawo zokufinyelela kufanele zibekwe kuphi. Isikhathi eside, ukwakheka kwephethini kwahlala kungashintshile futhi kwanda noma kwehle kuphela ngokulingana nezici ze-antenna.
Izinto ze-antenna zesimanje ziya ngokuya zilawuleka futhi zivumela izinguquko eziguqukayo kuphethini yendawo yokusakazwa kwesignali ngesikhathi sangempela.
Umfanekiso ongakwesokunxele ongenhla ubonisa umgomo wokusakazeka kwegagasi lomsakazo kusetshenziswa uthi olujwayelekile lwe-omnidirectional. Ngokwandisa amandla esignali, singashintsha kuphela irediyasi yokukhava ngaphandle kwekhono lokuba nomthelela omkhulu kwikhwalithi yokusetshenziswa kwesiteshi - i-KQI (Izinkomba Zekhwalithi Ebalulekile). Futhi le nkomba ibaluleke kakhulu lapho uhlela ukuxhumana ngaphansi kwezimo zokuhamba njalo kwedivayisi yokubhalisa endaweni engenantambo.
Isixazululo senkinga kwakuwukusetshenziswa kwenani elikhulu lezimpondo ezincane, umthwalo ongalungiswa ngesikhathi sangempela, kwakhiwe amaphethini okusakaza ngokuya ngendawo yomsebenzisi.
Ngakho, kwakungenzeka ukusondela ekusebenziseni ubuchwepheshe be-MU-MIMO (Multi-User Multiple Input, Multiple Output) ubuchwepheshe. Ngosizo lwayo, indawo yokufinyelela nganoma yisiphi isikhathi ikhiqiza ukugeleza kwemisebe eqondiswe ngqo kumadivayisi abhalisile.
Ukusuka ku-physics kuye kumazinga angama-802.11
Njengoba amazinga e-Wi-Fi ethuthuka, imigomo yokusebenza ngelendlalelo esibonakalayo senethiwekhi yashintsha. Ukusetshenziswa kwezinye izindlela zokuguquguquka kwenze kwaba nokwenzeka - ukuqala ngezinguqulo ze-802.11g/n - ukufaka inani elikhulu kakhulu lolwazi endaweni yesikhathi futhi, ngokufanele, kusetshenzwe nenani elikhulu labasebenzisi. Phakathi kokunye, lokhu kwafezwa ngokusebenzisa ukugeleza kwendawo. Futhi ukuguquguquka okusanda kutholwa ngokobubanzi besiteshi kwenze kwaba nokwenzeka ukukhiqiza izinsiza ezengeziwe ze-MIMO.
Ukugunyazwa kwezinga le-Wi-Fi 7 kuhlelelwe unyaka ozayo. Yini ezoshintsha lapho kufika? Ngaphezu kokwenyuka okujwayelekile kwesivinini kanye nokwengezwa kwebhendi engu-6 GHz, kuzokwazi ukusebenza namashaneli ahlanganisiwe abanzi, njenge-320 MHz. Lokhu kuyathakazelisa ikakhulukazi kumongo wezinhlelo zokusebenza zezimboni.
I-Theory Wi-Fi 6 throughput
Ifomula yethiyori yokubala isivinini se-Wi-Fi 6 iyinkimbinkimbi impela futhi incike kumapharamitha amaningi, iqala ngenani lemifudlana yendawo futhi iphethe ngolwazi esingalufaka ku-subcarrier (noma izithwali ezingaphansi, uma kukhona ezimbalwa them) ngeyunithi yesikhathi.
Njengoba ubona, okuningi kuncike ekugelezeni kwendawo. Kodwa ngaphambili, ukwanda kwenani labo kuhlanganiswe nokusetshenziswa kwe-STC (Space-Time Coding) kanye ne-MRC (Maximum Ratio Combining) kwenze kwaba kubi kakhulu ukusebenza kwesixazululo esingenantambo sisonke.
Ubuchwepheshe Obusha Bezendlalelo Zomzimba Ezibalulekile
Ake siqhubekele kubuchwepheshe obubalulekile bongqimba olubonakalayo - futhi siqale ngesendlalelo sokuqala semodeli yenethiwekhi ye-OSI.
Masikhumbule ukuthi i-OFDM isebenzisa inombolo ethile yabathwali abangaphansi, okuthi, ngaphandle kokuthintana, ikwazi ukudlulisa inani elithile lolwazi.
Esibonelweni, sisebenzisa ibhendi engu-5,220 GHz, equkethe amashaneli angama-48. Ngokuhlanganisa lesi siteshi, sithola inombolo enkulu yezinkampani zenethiwekhi, ngayinye esebenzisa isikimu sayo sokumodela.
I-Wi-Fi 5 isebenzisa i-quadrature amplitude modulation 256 QAM (Quadrature Amplitude Modulation), ekuvumela ukuthi wakhe inkambu yamaphoyinti angu-16 x 16 ngaphakathi kwefrikhwensi yenkampani yenethiwekhi ngesikhathi esisodwa, ehlukile ngobude nesigaba. Ukuphazamiseka ukuthi nganoma isiphi isikhathi isiteshi esisodwa kuphela esingasakaza ngefrikhwensi yenkampani yenethiwekhi.
I-Orthogonal frequency division multiplexing (OFDMA) yavela emhlabeni wama-opharetha eselula, yasakazeka ngesikhathi esisodwa ne-LTE futhi isetshenziselwa ukuhlela i-downlink (isiteshi sokuxhumana kobhalisile). Ikuvumela ukuthi usebenze nesiteshi ezingeni lalokho okubizwa ngokuthi amayunithi wezinsiza. Lawa mayunithi asiza ukuhlukanisa ibhulokhi ibe inombolo ethile yezingxenye. Ngaphakathi kwebhulokhi, ngesikhathi ngasinye asikwazi ukusebenza ngokuqinile ngento eyodwa ekhiphayo (umsebenzisi noma indawo yokufinyelela), kodwa sihlanganise inqwaba yezinto. Lokhu kukuvumela ukuba uzuze imiphumela emangalisayo.
Ukuxhumeka okulula kweziteshi ku-Wi-Fi 6
I-Channel Bonding ku-Wi-Fi 6 ikuvumela ukuthi uthole iziteshi ezihlanganisiwe ezinobubanzi obungu-20 kuye ku-160 MHz. Ngaphezu kwalokho, ukuxhumana akudingeki ukuba kwenziwe kumabanga aseduze. Isibonelo, ibhulokhi eyodwa ingathathwa kubhendi engu-5,17 GHz, neyesibili kubhendi engu-5,135 GHz. Lokhu kukuvumela ukuthi wakhe indawo yomsakazo ngokuguquguqukayo ngisho nalapho kukhona iziphazamiso ezinamandla noma useduze nezinye iziteshi ezihlala ziphuma.
Ukusuka ku-SIMO kuye ku-MIMO
Indlela ye-MIMO ibilokhu inathi njalo. Kudala, ukuxhumana kweselula kwakufanele kukhawulelwe kumodi ye-SIMO, eyayisho ukuba khona kwezimpondo ezimbalwa esiteshini sababhalisile, ngesikhathi esisodwa zisebenzela ukuthola ulwazi.
I-MU-MIMO yakhelwe ukudlulisa imininingwane kubasebenzisi kusetshenziswa sonke isitokwe se-antenna samanje. Lokhu kususa imikhawulo ebibekwe ngaphambilini yiphrothokholi ye-CSMA/CA ehlobene nokuthumela amathokheni kumadivayisi abhalisile ukuze adluliselwe. Manje abasebenzisi sebemunye eqenjini futhi ilungu ngalinye leqembu lithola ingxenye yalo yesisetshenziswa sephoyinti lokufinyelela, kunokulinda isikhathi salo.
Ukwakhiwa kwe-radio beam
Umthetho obalulekile wokusebenza kwe-MU-MIMO ukugcina indlela yokusebenza ye-antenna engeke iholele ekunqwabelaneni kwamaza omsakazo kanye nokulahlekelwa kolwazi ngenxa yokwengezwa kwesigaba.
Lokhu kudinga izibalo zezibalo eziyinkimbinkimbi ohlangothini lwephoyinti lokufinyelela. Uma itheminali isekela lesi sici, i-MU-MIMO iyivumela ukuthi itshele indawo yokufinyelela ukuthi kuthatha isikhathi esingakanani ukuthola isignali ku-antenna ngayinye. Futhi indawo yokufinyelela, yona, ilungisa izinti zayo ukuze zakhe i-beam eqondiswe kahle.
Lokhu kusinikani ngokujwayelekile?
Imibuthano emhlophe enezinombolo kuthebula ikhombisa izimo zamanje zokusebenzisa i-Wi-Fi yezizukulwane ezedlule. Imibuthano eluhlaza okwesibhakabhaka (bona umfanekiso ngenhla) ichaza amandla e-Wi-Fi 6, futhi okumpunga kuyindaba yesikhathi esizayo esiseduze.
Izinzuzo eziyinhloko ezilethwa izixazululo ezintsha ezinikwe amandla i-OFDMA zihlobene namayunithi wezinsiza asetshenziswe ezingeni elifana ne-TDM (Time Division Multiplexing). Lokhu bekungakaze kube njalo nge-Wi-Fi ngaphambilini. Lokhu kukuvumela ukuthi ulawule ngokucacile umkhawulokudonsa owabelwe, uqinisekise isikhathi esincane sokuhamba kwesignali phakathi nendawo kanye nezinga elidingekayo lokuthembeka. Ngenhlanhla, akekho ongabaza ukuthi izinkomba zokuthembeka kwe-Wi-Fi zidinga ukuthuthukiswa.
Umlando uhamba ngokuzungeza, futhi isimo samanje siyefana nalesi esakheka eduze kwe-Ethernet ngesikhathi esisodwa. Ngisho nangaleso sikhathi, kwasungulwa umbono wokuthi i-CSMA/CD (Carrier Sense Multiple Access with Collision Detection) ayinikezi noma yikuphi ukuphuma okuqinisekisiwe. Futhi lokhu kwaqhubeka kwaze kwaba ukushintshela ku-IEEE 802.3z.
Ngokuqondene namamodeli wohlelo lokusebenza olujwayelekile, njengoba ubona, ngesizukulwane ngasinye se-Wi-Fi, izimo zokusetshenziswa kwayo ziyaphindaphindeka, zizwela kakhulu ukubambezeleka, okujwayelekile. kanye nokwethembeka.
Futhi futhi mayelana nendawo ebonakalayo
Hhayi-ke, manje ake sikhulume ngokuthi imvelo entsha yakhiwa kanjani. Uma usebenzisa i-CSMA/CA ne-OFDM, ukwanda kwenani lama-STA asebenzayo kuholele ekwehleni okukhulu kokuphuma kwesiteshi esingu-20 MHz. Lokhu kube ngenxa yalokho osekushiwo: hhayi ubuchwepheshe obusha kakhulu i-STC (I-Space-Time Coding) kanye ne-MRC (I-Maximum Ratio Combining).
I-OFDMA, ngokusebenzisa amayunithi wezinsiza, ingasebenzisana ngempumelelo neziteshi zamabanga amade nezinamandla aphansi. Sithola ithuba lokusebenza ebangeni elifanayo lenkampani yenethiwekhi nabasebenzisi abasebenzisa amanani ahlukene wezinsiza. Umsebenzisi oyedwa angakwazi ukusebenzisa iyunithi eyodwa, kanti omunye - wonke amanye.
Kungani yayingekho i-OFDMA ngaphambilini?
Futhi ekugcineni, umbuzo oyinhloko: kungani kwakungekho OFDMA ngaphambili? Okuxakayo ukuthi, konke kwavela emalini.
Isikhathi eside kwakukholelwa ukuthi intengo yemodyuli ye-Wi-Fi kufanele ibe encane. Lapho iphrothokholi yethulwa ekusebenzeni kwezentengiselwano ngo-1997, kwanqunywa ukuthi izindleko zokukhiqiza zemojula enjalo azikwazi ukudlula i-$1. Ngenxa yalokho, ukuthuthukiswa kobuchwepheshe kwathatha indlela engafanele. Lapha asicabangeli i-opharetha i-LTE, lapho i-OFDMA isetshenziswe isikhathi eside impela.
Ekugcineni, iqembu elisebenzayo le-Wi-Fi lanquma ukuthatha lezi ntuthuko emhlabeni wabasebenzisi be-telecom futhi lizilethe emhlabeni wamanethiwekhi ebhizinisi. Umsebenzi oyinhloko kwakuwukushintshela ekusetshenzisweni kwezinto ezisezingeni eliphakeme, njengezihlungi nama-oscillator.
Kungani bekunzima kangaka ngathi ukusebenza kumakhodi we-MRC amadala ngokuphazanyiswa noma ngaphandle kokuphazamiseka? Ngoba i-MVDR (Minimum Variance Distortionless Response) indlela yokwenza i-beamforming ikhulise ngokuphawulekayo inani lamaphutha ngokushesha nje lapho sizama ukuhlanganisa inombolo enkulu yamaphoyinti okudlulisa. I-OFDMA ikufakazele ukuthi le nkinga ingaxazululeka.
Impi yokulwa nokuphazamiseka manje isisekelwe kwizibalo. Uma iwindi lokudlulisela lilide ngokwanele, ukuphazamiseka okuguquguqukayo okuwumphumela kubangela izinkinga. Ama-algorithms amasha okusebenza enza kube nokwenzeka ukuwagwema, asuse umthelela hhayi nje wokuphazamiseka okuhlobene nokudluliswa kwe-Wi-Fi, kodwa nanoma yikuphi okunye okwenzeka kulobu bubanzi.
Ngenxa yokumelana nokuphazamiseka okuguquguqukayo, singakwazi ukuzuza izinzuzo ezingafika ku-11 dB ngisho nasezindaweni eziyinkimbinkimbi ezihlukahlukene. Ukusetshenziswa kwezixazululo ze-algorithmic zikaHuawei kwenze kwaba nokwenzeka ukuzuza ukuthuthukiswa okujulile lapho bekudingekile khona - ezisombululweni zasendlini. Okuhle ku-5G akukuhle ngempela endaweni ye-Wi-Fi 6. Izindlela ezinkulu ze-MIMO ne-MU-MIMO ziyahluka endabeni yezixazululo zasendlini nezangaphandle. Lapho kudingekile, kufanelekile ukusebenzisa izixazululo ezibizayo, njengaku-5G. Kodwa ezinye izinketho ziyadingeka, njenge-Wi-Fi 6, engaletha ukubambezeleka namanye amamethrikhi esiwalindele kubathwali.
Siboleka kubo amathuluzi azoba wusizo kithi njengabathengi bebhizinisi, konke lokhu ngomzamo wokuhlinzeka ngendawo ebonakalayo esingathembela kuyo.
