Yini ethokozisayo nge-Wi-Fi 6 kaHuawei

Sikulethela umbono kaHuawei we-Wi-Fi 6 - ubuchwepheshe uqobo kanye nezinto ezintsha ezihlobene, ikakhulukazi maqondana nezindawo zokufinyelela: yini entsha ngabo, lapho bezothola khona uhlelo lokusebenza olufaneleka kakhulu noluwusizo ngo-2020, yiziphi izixazululo zobuchwepheshe ezibanika zona. izinzuzo eziyinhloko zokuncintisana nokuthi ulayini we-AirEngine ngokuvamile uhlelwa kanjani.

Kwenzekani kubuchwepheshe obungenawaya namuhla

Phakathi neminyaka lapho izizukulwane ezedlule ze-Wi-Fi - eyesine neyesihlanu - zithuthuka, umqondo wehhovisi elingenazintambo, okungukuthi, indawo yehhovisi engenazintambo ngokuphelele, yasungulwa embonini. Kodwa kusukela ngaleso sikhathi, amanzi amaningi adlulile ngaphansi kwebhuloho, futhi izidingo zebhizinisi maqondana ne-Wi-Fi zishintshile ngokufanele nangobuningi: izidingo zomkhawulokudonsa ziye zanda, ukunciphisa ukubambezeleka kuye kwaba okubucayi, futhi ngokuqhubekayo, isidingo sokucindezela kakhulu xhuma inombolo enkulu yabasebenzisi.

Ngo-2020, sekuvele isimo sezinhlelo zokusebenza ezintsha okumele sisebenze ngokuthembekile kumanethiwekhi e-Wi-Fi. Umfanekiso ubonisa izindawo eziyinhloko lezo zicelo ezihlobene nazo. Kafushane ngabambalwa babo.

A. Okungokoqobo okungathandwa kwabathelisi esikubona. Isikhathi eside, izifinyezo ze-VR ne-AR zivele ezethulweni zabathengisi be-telecom, kodwa bambalwa abantu abaqonda ukuthi ukusetshenziswa kobuchwepheshe obulandela lezi zincwadi kwakuyini. Namuhla bangena ngokushesha ezimpilweni zethu, okubonakala emikhiqizweni yeHuawei. Ngo-Ephreli, sethule i-smartphone ye-Huawei P40 futhi ngesikhathi esifanayo sethula - kuze kube manje kuphela e-China - isevisi ye-Huawei Amamephu ngomsebenzi we-AR Maps. Akuyona nje “i-GIS enamahologram”. Okungokoqobo okungathandwa kwabathelisi esikubona kwakhiwe ngokujulile ekusebenzeni kwesistimu: ngosizo lwalo, akubizi lutho "ukubamba" ngokoqobo ulwazi mayelana nenhlangano ethile ehhovisi layo likhona esakhiweni, hlela umzila endaweni ezungezile - futhi konke lokhu ku-3D. ifomethi kanye nekhwalithi ephezulu kakhulu.

I-AR izophinde ibone intuthuko ejulile emkhakheni wezemfundo nokunakekelwa kwezempilo. Kuyafaneleka futhi ekukhiqizeni: isibonelo, ukuze uqeqeshe abasebenzi ukuthi benze kanjani ezimweni eziphuthumayo, kunzima ukuqhamuka nokuthile okungcono kunama-simulators eqinisweni elingathandwa kwabathelisi esikubona.

B. Izinhlelo zokuphepha ezinokugadwa kwevidiyo. Futhi okubanzi nakakhulu: noma yisiphi isixazululo sevidiyo esihlangabezana nezindinganiso zokuchazwa okuphezulu kakhulu. Asikhulumi nge-4K kuphela, kodwa futhi nge-8K. Abakhiqizi abahamba phambili bamathelevishini namaphaneli olwazi bathembisa ukuthi amamodeli akhiqiza izithombe ze-8K UHD azovela ebangeni lemikhiqizo yawo phakathi no-2020. Kunengqondo ukucabanga ukuthi abasebenzisi bokugcina bazophinde bafune ukubuka amavidiyo ekhwalithi ephezulu kakhulu nge-bitrate ekhuphuke kakhulu.

B. Ibhizinisi eliqondile, futhi okokuqala kukho konke okudayisa. Ake sithathe njengesibonelo ILidl - elinye lamaketanga esitolo esikhulu kunazo zonke eYurophu. Usebenzisa i-Wi-Fi entsha, ngokusekelwe ku-IoT izimo zokusebenzelana nabathengi, ikakhulukazi, yethule amathegi entengo kagesi e-ESL, iwahlanganisa ne-CRM yayo.

Ngokuqondene nokukhiqizwa kwezinga elikhulu, isipiliyoni seVolkswagen siyaphawuleka, esifake i-Wi-Fi evela kuHuawei emafektri ayo futhi iyisebenzisela ukuxazulula izinkinga ezihlukahlukene. Phakathi kwezinye izinto, inkampani ithembele ku-Wi-Fi 6 ukuze isebenzise amarobhothi ahambahamba efekthri, iskena izingxenye ngesikhathi sangempela kusetshenziswa izimo ze-AR, njll.

G. "Amahhovisi ahlakaniphile" futhi imele isikhala esikhulu sokuqanjwa kabusha okusekelwe ku-Wi-Fi 6. Inani elikhulu lezimo ze-inthanethi Yezinto "zesakhiwo esihlakaniphile" sezivele zicatshangelwa, okuhlanganisa nokulawula ukuphepha, ukulawula ukukhanya, njll.

Akumele sikhohlwe ukuthi izinhlelo zokusebenza eziningi zithuthela emafini, futhi ukufinyelela efwini kudinga uxhumano lwekhwalithi ephezulu, oluzinzile. Kungakho uHuawei esebenzisa isiqubulo futhi elwela ukusebenzisa umgomo othi “100 Mbps yonke indawo”: I-Wi-Fi isiba indlela eyinhloko yokuxhuma ku-inthanethi, futhi kungakhathaliseki indawo yomsebenzisi, sibophekile ukumnikeza amandla aphezulu. izinga lolwazi lomsebenzisi.

Uhlongoza kanjani uHuawei ukuphatha indawo yakho ye-Wi-Fi 6

Njengamanje, i-Huawei iphromotha isisombululo esenziwe ngomumo se-Cloud Campus, okuhloswe ngaso, ngakolunye uhlangothi, ekusizeni ukuphatha yonke ingqalasizinda kusuka efwini, futhi ngakolunye uhlangothi, ekusebenzeni njengenkundla yokusebenzisa okusha. Izimo ze-IoT, kungaba ukuphathwa kwesakhiwo, ukuqapha imishini noma, isibonelo, uma siphendukela ecaleni elivela emkhakheni wezokwelapha, ukuqapha imingcele ebalulekile yesiguli.

Ingxenye ebalulekile ye-ecosystem ezungeze i-Cloud Campus imakethe. Isibonelo, uma umthuthukisi edale idivayisi yokugcina futhi wayihlanganisa nezixazululo ze-Huawei ngokubhala isofthiwe efanele, unelungelo lokwenza umkhiqizo wakhe utholakale kwamanye amakhasimende ethu esebenzisa imodeli yesevisi.

Njengoba inethiwekhi ye-Wi-Fi iba yisisekelo sokusebenza kwebhizinisi, izindlela zakudala zokuyiphatha azanele. Ngaphambilini, umlawuli waphoqeleka ukuthi abone ukuthi kwenzekani ngenethiwekhi cishe ngesandla, emba izingodo. Le ndlela yokwesekwa esebenzayo manje iyashoda. Kudingeka amathuluzi okuqapha nokuphatha ingqalasizinda engenazintambo ukuze umlawuli aqonde kahle ukuthi kwenzekani kuyo: yiliphi izinga lokuhlangenwe nakho komsebenzisi elinikezayo, noma abasebenzisi abasha bangaxhuma kuyo ngaphandle kwezinkinga, noma ngabe yimaphi amaklayenti adinga "kudluliselwe" endaweni yokufinyelela engumakhelwane (AP), isiphi isimo indawo ngayinye yenethiwekhi ekuyo, njll.

Kumadivayisi e-Wi-Fi 6, i-Huawei inawo wonke amathuluzi okusebenza, ukuhlaziya okujulile nokulawula okwenzeka kunethiwekhi. Lokhu kuthuthukiswa kusekelwe ngokuyinhloko kuma-algorithms wokufunda komshini.

Lokhu kwakungenakwenzeka kumaphuzu okufinyelela ochungechunge lwangaphambilini, njengoba ayengasekeli izivumelwano ezifanele ze-telemetry, futhi ngokuvamile ukusebenza kwalawo madivayisi akuzange kuvumele lokhu kusebenza ukuthi kusetshenziswe ngendlela izindawo zethu zokufinyelela zesimanje ezivumela ngayo.

Yiziphi izinzuzo ze-Wi-Fi 6 ejwayelekile

Isikhathi eside, isikhubekiso ekusabalaleni kwe-Wi-Fi 6 sahlala siyiqiniso lokuthi bekunamadivayisi angenasiphelo azosekela izinga le-IEEE 802.11ax futhi akwazi ukubona ngokugcwele izinzuzo ezitholakala endaweni yokufinyelela. Kodwa-ke, uguquko lwenzeka embonini, futhi thina, njengomthengisi, sinikela ngakho ngamandla ethu onke: I-Huawei ithuthukise ama-chipsets ayo hhayi kuphela emikhiqizweni yezinkampani, kodwa namadivayisi eselula nasekhaya.

- Ulwazi mayelana ne-Wi-Fi 6+ evela ku-Huawei luzungeza ku-inthanethi. Kuyini lokhu?
- Icishe ifane ne-Wi-Fi 6E. Konke kuyafana, kuphela ngokwengezwa kwebanga lefrikhwensi engu-6 GHz. Amazwe amaningi okwamanje acabanga ukuyenza itholakalele i-Wi-Fi 6.

- Ingabe i-interface ye-6 GHz yomsakazo izosetshenziswa kumojula efanayo okwamanje esebenza ku-5 GHz?
— Cha, kuzoba nama-antenna akhethekile azosebenza ku-6 GHz frequency range. Izindawo zokufinyelela zamanje azisekeli i-6 GHz, ngisho noma isofthiwe yazo ibuyekeziwe.

Namuhla, amadivayisi aboniswe emfanekisweni ayingxenye ye-hi-end. Ngesikhathi esifanayo, i-router yasekhaya ye-Huawei AX3, ehlinzeka ngesivinini esifika ku-2 Gbit/s nge-interfaces yomoya, ayihlukile ngentengo kusukela kumaphuzu okufinyelela esizukulwane sangaphambilini. Ngakho-ke, kukhona zonke izizathu zokukholelwa ukuthi ngo-2020, ububanzi obubanzi bamadivayisi aphakathi nendawo ngisho neleveli yokungena azothola ukwesekwa kwe-Wi-Fi 6. Ngokwezibalo zokuhlaziya zikaHuawei, ngo-2022, ukuthengiswa kwezindawo zokufinyelela ezisekela i-Wi-Fi 6 uma kuqhathaniswa nalawo akhelwe ku-Wi-Fi 5 kuzoba ngu-90 kuya ku-10%.

Onyakeni nesigamu, isikhathi se-Wi-Fi 6 sizofika ekugcineni.

Okokuqala, i-Wi-Fi 6 yakhelwe ukwenza inethiwekhi engenantambo iyonke isebenze kahle. Ngaphambilini, isiteshi ngasinye besinikezwa isikhathi esilandelanayo futhi sithatha isiteshi sonke esingu-20 MHz, okuphoqa abanye ukuthi basilinde ukuze sithumele ithrafikhi. Manje lawa ma-20 MHz asikwa abe abathwali abancane, ahlanganiswe abe amayunithi wensiza, afika ku-2 MHz, futhi iziteshi ezifika kweziyisishiyagalolunye zingasakaza kanyekanye endaweni eyodwa yesikhathi. Lokhu kubangela ukwanda okukhulu ekusebenzeni kwayo yonke inethiwekhi.

Sesivele sishilo ukuthi izikimu zokuguquguqula eziphakeme zengezwe ezingeni lesizukulwane sesithupha: 1024-QAM uma kuqhathaniswa no-256 wangaphambilini. Ngakho-ke, inkimbinkimbi yombhalo wekhodi inyuke ngo-25%: uma ngaphambilini besidlulisela ulwazi olufika ku-8 bits ngohlamvu ngalunye, manje 10 amabhithi.

Inani lokugeleza kwendawo nalo linyukile. Ezindinganisweni zangaphambilini bezine, kanti manje sezifika kweziyisishiyagalombili, kanti kwaHuawei amadala afinyelela amaphuzu afinyelela kweshumi nambili.

Ngaphezu kwalokho, i-Wi-Fi 6 iphinde isebenzisa i-2,4 GHz frequency range, okwenza kube nokwenzeka ukukhiqiza ama-chipset angabizi kakhulu kumatheminali asekela i-Wi-Fi 6 futhi kuxhume inombolo enkulu yamadivayisi, kungaba amamojula agcwele e-IoT noma amanye kakhulu. izinzwa ezishibhile

Okubaluleke kakhulu ukuthi izinga lisebenzisa ubuchwepheshe obuningi bokusetshenziswa ngokuphumelelayo kwe-spectrum yomsakazo, okuhlanganisa ukusetshenziswa kabusha kwamashaneli namaza. Okokuqala, Umbala we-Basic Service Set (BSS) ufanelwe ukushiwo, okuvumela ukuthi ungazinaki izindawo zokufinyelela zabanye abantu ezisebenza esiteshini esifanayo, futhi ngesikhathi esifanayo “ulalele” eyakho.

Yiziphi izindawo zokufinyelela ze-Wi-Fi 6 ezivela ku-Huawei esicabanga ukuthi kufanele zenziwe kuqala?

Izithombe zibonisa amaphuzu okufinyelela anikezwa iHuawei namuhla futhi, okubaluleke kakhulu, azoqala ukuwahlinzeka maduzane, aqale ngemodeli eyisisekelo ye-AirEngine 5760 futhi agcine ngeziphezulu.

Izindawo zethu zokufinyelela ezisekela izinga le-802.11ax zisebenzisa uhla lonke lwezisombululo zobuchwepheshe ezihlukile.

• Ukutholakala kwemojuli ye-IoT eyakhelwe ngaphakathi noma ikhono lokuxhuma eyangaphandle. Kuzo zonke izindawo zokufinyelela, ikhava ephezulu manje iyavuleka, futhi ngaphansi kwayo kufihlwe izikhala ezimbili zamamojula we-IoT, cishe noma yiluphi uhlobo. Isibonelo, kusuka ku-ZigBee, elungele ukuxhuma amasokhethi ahlakaniphile noma ama-relay, izinzwa ze-telemetry, njll. Noma ezikhethekile, isibonelo, ngokusebenza ngamathegi amanani e-elekthronikhi (uHuawei usebenzise isisombululo esinjalo ngokubambisana nenkampani. I-Hanshow). Futhi, amanye amaphoyinti okufinyelela ochungechunge anesixhumi esengeziwe se-USB, futhi imojula ye-inthanethi Yezinto ingaxhunywa ngayo.
• Isizukulwane esisha sobuchwepheshe be-Smart Antenna. Indawo yokungena inezindlu ezingafinyelela kwezingu-16, ezakha imifudlana efinyelela ku-12 yendawo. “Ama-antenna ahlakaniphile” anjalo akwenza kube nokwenzeka, ikakhulukazi, ukukhulisa irediyasi (futhi kususwe “izindawo ezifile”) ngenxa yokuthi ngayinye yazo inohlu olugxilile lokusatshalaliswa kwesignali yomsakazo futhi “iyaqonda” lapho indawo yendawo itholakala ngesikhathi esisodwa noma elinye iklayenti.
• Irediyasi enkulu yokusakaza isignali kusho ukuthi i-RSSI yeklayenti, noma ileveli yesiginali yokwamukela, nayo izoba phezulu. Ezivivinyweni eziqhathaniswayo, lapho kuhlolwa indawo yokufinyelela evamile ye-omni-directional kanye neyodwa efakwe izimpondo ezihlakaniphile ihlolwa, okwesibili kuba namandla aphindwe kabili - okungeziwe okungu-3 dB.

Uma usebenzisa ama-antenna ahlakaniphile, ayikho i-asymmetry yesignali, njengoba ukuzwela kwendawo yokufinyelela kukhula ngokulinganayo. I-antenna ngayinye kweziyi-16 isebenza njengesibuko: ngenxa yesimiso sokusakazwa kwe-multipath, lapho iklayenti lithumela umsebe wolwazi, igagasi lomsakazo elihambisanayo, elivela ezithiyo ezihlukahlukene, lishaya zonke izinti eziyi-16. Khona-ke iphuzu, lisebenzisa ama-algorithms alo angaphakathi, lengeza amasiginali atholiwe futhi libuyisela idatha efakwe ikhodi ngezinga elikhulu lokuthembeka.

• Zonke izindawo ezintsha zokufinyelela ze-Huawei ziyasebenza Ubuchwepheshe be-SDR (Software-Defined Radio). Siyabonga ngakho, kuye ngesimo esithandwayo sokusebenzisa ingqalasizinda engenazintambo, umlawuli unquma ukuthi amamojula amathathu omsakazo kufanele asebenze kanjani. Ukuthi mingaki imifudlana yendawo okufanele yabelwe eyodwa noma enye nayo inqunywa ngokushintshashintshayo. Isibonelo, ungenza amamojula omsakazo amabili asebenze ukuxhuma amaklayenti (eyodwa ebangeni le-2,4 GHz, enye ebangeni elingu-5 GHz), kanti eyesithathu isebenza njengesithwebuli, eqapha okwenzekayo ngendawo yomsakazo. Noma sebenzisa amamojula amathathu ngokukhethekileyo ukuxhuma amaklayenti.

  Esinye isimo esivamile lapho kungekho amaklayenti amaningi kakhulu kunethiwekhi, kodwa amadivaysi awo asebenzisa izinhlelo zokusebenza ezinomthwalo ophezulu ezidinga umkhawulokudonsa ophezulu. Kulokhu, konke ukusakaza kwendawo kuboshelwe kububanzi befrikhwensi obungu-2,4 no-5 GHz, futhi amashaneli ahlanganisiwe ukuze anikeze abasebenzisi umkhawulokudonsa ongu-20, kodwa ongu-80 MHz.

• Izindawo zokufinyelela ziyasetshenziswa izihlungi ngokuhambisana nokucaciswa kwe-3GPP, ukuze kuhlukaniswe amamojula omsakazo okungenzeka asebenze kumafrikhwensi ahlukene ebangeni elingu-5 GHz ukusuka kwelinye, ukuze kugwenywe ukuphazamiseka kwangaphakathi.

Izindawo zokufinyelela zinikeza ukusebenza ngezindlela ezihlukene. Enye yazo i-RTU (Ilungelo Lokusebenzisa). Kafushane, isimiso sayo esiyisisekelo simi kanje. Amamodeli ochungechunge ngalunye azonikezwa ngenguqulo evamile, isibonelo ngokusakazwa kwendawo okuyisithupha. Ngaphezu kwalokho, ngosizo lwelayisense, kuzokwaziwa ukunweba ukusebenza kwedivayisi futhi kusebenze ukusakazwa okwengeziwe okubili, okuveza amandla ezingxenyekazi zekhompuyutha atholakala kuyo. Enye inketho: mhlawumbe, ngokuhamba kwesikhathi, iklayenti izodinga ukwaba isikhombimsebenzisi somsakazo esengeziwe sokuskena ama-airwaves, futhi ukuze siyisebenzise, ​​​​kuzokwanela ukuthenga ilayisensi futhi.

Engxenyeni engezansi kwesokudla yomfanekiso odlule, izindawo zokufinyelela zinezincwadi zedijithali, isibonelo 2 + 2 + 4 ngokuphathelene ne-AirEngine 5760. Iphuzu liwukuthi i-AP inamamojula amathathu omsakazo ozimele. Izinombolo zibonisa ukuthi mangaki ama-spatial streams azokwabelwa imojuli ngayinye yomsakazo. Ngokufanelekile, inani lemicu lithinta ngokuqondile ukuphuma kwebanga elinikeziwe. Uchungechunge olujwayelekile luhlinzeka ngokusakaza okungafika kwabayisishiyagalombili. Okuthuthukisiwe - kufika ku-12. Ekugcineni, i-flagship (imishini yokuphela) - kufika ku-16.

Indlela ulayini we-AirEngine osebenza ngayo

Kusukela manje kuqhubeke, uhlobo olujwayelekile lwezixazululo ezingenantambo zebhizinisi yi-AirEngine. Njengoba ubona kalula, ukuklanywa kwezindawo zokufinyelela kuphefumulelwe izinjini zomoya zendiza: ama-diffuser akhethekile abekwe endaweni yangaphambili nangemuva yamadivayisi.

Uchungechunge lokuqala lwamadivayisi e-AirEngine 5760-51 yiwo afinyeleleka kakhulu kubathengi futhi aklanyelwe izimo ezivame kakhulu. Isibonelo, ukudayisa. Kodwa-ke, zilungele izidingo zehhovisi, zisebenza emhlabeni wonke ngokuya ngenqwaba yobuchwepheshe esetshenziswa kuzo kanye nezindleko.

Uchungechunge oludala olulandelayo luyi-5760-22W. Kuhlanganisa amaphuzu okufinyelela odongeni-plate, angamisiwe ophahleni, kodwa abekwe etafuleni, ekhoneni noma ahlanganiswe odongeni. Zifaneleka kakhulu kulezo zimo lapho kudingekile ukumboza inani elikhulu lamakamelo amancane ngokuxhumana okungenantambo (esikoleni, esibhedlela, njll.), lapho uxhumano lwezintambo luyadingeka futhi.

Imodeli ye-5760-22W (wall-plate) inikeza uxhumano lwe-2,5 Gbit/s ngezixhumi ezibonakalayo zethusi, futhi ine-transceiver ye-SFP ekhethekile ye-PON. Ngakho, isendlalelo sokufinyelela singasetshenziswa ngokuphelele phezu kwenethiwekhi ye-optical ye-passive futhi indawo yokufinyelela ingaxhunywa ngqo kule nethiwekhi ye-GPON.

Ububanzi buhlanganisa kokubili izindawo zokufinyelela zangaphakathi nangaphandle. Lezi zamuva zihlukaniswa kalula ngohlamvu R (ongaphandle) egameni. Ngakho, i-AirEngine 8760-X1-PRO yakhelwe ukusetshenziswa endlini, kuyilapho i-AirEngine 8760R-X1 yakhelwe izimo zangaphandle. Uma igama lendawo yokufinyelela liqukethe uhlamvu E (yangaphandle), kusho ukuthi izimpondo zayo azakhelwe ngaphakathi, kodwa zingaphandle.

Imodeli ephezulu - i-AirEngine 8760-X1-PRO ifakwe ezintathu-gigabit interfaces ezintathu ukuze ixhumeke. Ezimbili zazo ziyithusi, futhi zombili zisekela i-PoE / PoE-IN, ekuvumela ukuthi ugcine idivayisi ukuze uthole amandla. Okwesithathu okokuxhumana kwe-fiber optic (SFP+). Ake sicacise ukuthi lokhu kuyisixhumi esibonakalayo se-combo: kungenzeka ukuxhuma ngethusi kanye ne-optics. Futhi, ake sithi, akukho lutho olukuvimbela ukuthi uxhume indawo yokufinyelela nge-optics, futhi unikeze amandla avela kumjovo ngokusebenzisa isikhombimsebenzisi sethusi. Kufanele futhi sikhulume ngembobo ye-Bluetooth 5.0 eyakhelwe ngaphakathi. I-8760-X1-PRO inokusebenza okuphezulu kakhulu kulayini, njengoba isekela ukusakazwa kwendawo okungafika kwe-16.

— Ingabe izindawo zokufinyelela ze-PoE+ zinamandla anele?
- Ochungechungeni oludala (8760) i-POE++ iyadingeka. Kungakho i-CloudEngine s5732 ishintsha enamachweba e-multi-gigabit nokusekelwa kwe-802.3bt (kufika ku-60 W) ithengiswa ngoMeyi-Juni.

Ngaphezu kwalokho, i-AirEngine 8760-X1-PRO ithola ukupholisa okwengeziwe. Uketshezi luzungeza kumasekhethi amabili ngaphakathi kwendawo yokungena, lususa ukushisa okweqile ku-chipset. Lesi sixazululo siklanyelwe ngokuyinhloko ukuqinisekisa ukusebenza kwesikhathi eside kwedivayisi ngokusebenza okuphezulu: abanye abathengisi bamemezela ukuthi izindawo zabo zokufinyelela ziyakwazi ukuletha kufika ku-10 Gbps, nokho, ngemva kwemizuzu engu-15–20 la madivayisi athambekele ekushiseni ngokweqile, futhi ngenjongo yokunciphisa izinga lokushisa kwazo, ingxenye yokugeleza kwendawo iyavalwa, okunciphisa ukuphuma.

Amaphuzu okufinyelela ochungechunge aphansi awanakho ukupholisa uketshezi, kodwa awanayo inkinga yokushisa ngokweqile ngenxa yokusebenza okuphansi. Amamodeli eleveli emaphakathi - I-AirEngine 6760 - isekela ukusakazwa kwendawo okungafika kwezingu-12. Ziphinde zixhumeke nge-interfaces ye-gigabit eyishumi. Ngaphezu kwalokho, kukhona i-gigabit eyodwa - yokuxhuma ekushintsheni okukhona.

UHuawei ubelokhu enikeza isixazululo isikhathi eside uma kuqhathaniswa I-Agile Distributed Wi-Fi, okusho ukuba khona kwendawo yokufinyelela emaphakathi namamojula omsakazo oqhelile alawulwa yiyo. I-AP enjalo inesibopho sezinhlobo ezahlukene zemisebenzi yomthwalo omkhulu futhi ifakwe i-CPU ukuze iqalise i-QoS, yenza izinqumo mayelana nokuzulazula kwamakhasimende, umkhawulo womkhawulokudonsa, ukuqaphela izinhlelo zokusebenza, njll. Ngokulandelayo, amamojula omsakazo wangaphandle empeleni athumela ithrafikhi ngendlela yawo yokuqala. endaweni yokufinyelela emaphakathi futhi wenze iziguquli ukusuka ku-802.11 ukuya ku-802.3.

Lesi sinqumo sabonakala singadumile kakhulu eRussia. Noma kunjalo, umuntu akanakuhluleka ukuphawula izinzuzo zayo. Isibonelo, kungenzeka ukonga okuningi ezindlekweni zamalayisense, njengoba ungadingi ukuthenga ehlukile kumojula ngayinye yomsakazo. Ngaphezu kwalokho, umthwalo oyinhloko uwela ezindaweni zokufinyelela ezimaphakathi, okwenza kube lula ukuhambisa inethiwekhi enkulu engenazintambo ehlanganisa amashumi ezinkulungwane zezinto. Ngakho-ke sibuyekeze i-Agile Distributed Wi-Fi ukuze sisebenzise isitaki sethu sobuchwepheshe eduze ne-Wi-Fi 6.

Izindawo zokungena ngaphandle nazo zizotholakala ngoJuni. Uchungechunge oluphezulu phakathi kwamadivayisi angaphandle yi-8760R, enestakhi esiphezulu sobuchwepheshe (ikakhulukazi, kufika ku-16 ukusakazwa kwendawo okutholakalayo). Kodwa-ke, sicabanga ukuthi ezimweni eziningi i-6760R izoba yisinqumo esifanele. Ukufakwa emigwaqweni, njengomthetho, kuyadingeka ezindaweni zokugcina izimpahla, noma ukuhlanganisa amabhuloho angenantambo, noma kumasayithi obuchwepheshe, lapho ngezikhathi ezithile kuba nesidingo sokwamukela noma ukudlulisa i-telemetry noma ukuqoqa ulwazi kumatheminali okuqoqwa kwedatha.

Mayelana nezinzuzo zobuchwepheshe zezindawo zokufinyelela ze-AirEngine

Ngaphambilini, ukuhlukahluka kwama-antenna angaphandle ezindaweni zethu zokufinyelela bekulinganiselwe kakhulu. Kungaba khona izimpondo ze-omni-directional (dipole), noma eziqondise kancane kakhulu. Manje ukukhetha kubanzi. Isibonelo, i-antenna engu-70° / 70° ku-azimuth nokuphakama ibone ukukhanya. Ngokubeka ekhoneni lekamelo, ungakwazi ukumboza cishe yonke indawo phambi kwayo ngesignali.

Uhlu lwama-antenna ahlinzekwa ngezindawo zokufinyelela endlini luyakhula, futhi kungenzeka ukuthi kwengezwe okwengeziwe, okuhlanganisa nalawo akhiqizwa abanye abakhiqizi. Masenze ukubhuka: abekho abaqondisiwe phakathi kwabo. Uma udinga ukuhlela ukusabalala okugxile endlini, udinga ukusebenzisa amamodeli anezimpondo ze-dipole zangaphandle futhi uzibeke ngokwakho ukuze usakaze isignali yomsakazo, noma uthathe izindawo zokufinyelela ngezimpondo ezihlakaniphile ezakhelwe ngaphakathi.

Azikho izinguquko ezibalulekile mayelana nokufakwa kwezindawo zokufinyelela. Wonke amamodeli afakwe izinsimbi zokufakwa kokubili ophahleni nasodongeni noma ngisho nasepayipini (izinsimbi zensimbi). I-fastenings ibuye ifanele uphahla lwamahhovisi ngama-roof rails ohlobo lwe-Armstrong. Ukwengeza, ungakwazi ukufaka izingidi, okubaluleke kakhulu uma indawo yokufinyelela izosebenza endaweni yomphakathi.

Uma sibheka ngokushesha izinto ezintsha ezibalulekile zobuchwepheshe ezasetshenziswa ngesikhathi sokuthuthukiswa kwebanga lamamodeli I-AirEngine, uthola uhlu olufana nalolu.

• Ukukhiqiza okuphezulu kakhulu embonini sekuzuziwe. Kuze kube manje, uHuawei kuphela okwazile ukusebenzisa izimpondo eziyi-16 zokwamukela nokudlulisa imifudlana eyi-12 yendawo eyodwa endaweni eyodwa yokufinyelela. Ubuchwepheshe be-antenna ehlakaniphile ngendlela esetshenziswa ngayo yiHuawei abutholakali kunoma iyiphi enye inkampani okwamanje.
• I-Huawei inezixazululo ezikhethekile zokuthola ukubambezeleka okuphansi kakhulu. Lokhu kuvumela, ikakhulukazi, ukuzulazula okungenamthungo ngokuphelele kwamarobhothi e-warehouse.
• Njengoba wazi, ubuchwepheshe be-Wi-Fi 6 buhlanganisa izixazululo ezimbili zokufinyelela okuningi: I-OFDMA ne-Multi-User MIMO. Akekho noyedwa ngaphandle kukaHuawei osekwazile ukuhlela ukusebenza kwabo ngasikhathi sinye.
• Ukusekelwa kwe-inthanethi Yezinto kwezindawo zokufinyelela ze-AirEngine kubanzi ngendlela engakaze ibonwe ngaphambili.
• Ulayini uhlangabezana nezindinganiso eziphakeme kakhulu zokuphepha. Ngakho, wonke amaphoyinti ethu e-Wi-Fi 6 asebenzisa ukubethela ngokusekelwe kuphrothokholi ye-WPA3.

Yini enquma ukuphuma kwendawo yokufinyelela? Ngokusho kwethiyori kaShannon, kusuka ezintweni ezintathu:

• ngenani lemifudlana yendawo;
• ku-bandwidth;
• esilinganisweni sesignali-kuya-nomsindo.

Izixazululo zeHuawei endaweni ngayinye kwezintathu eziqanjwe zihlukile kulokho okunikezwa abanye abathengisi, futhi ngasinye siqukethe ukuthuthukiswa okuningi.

1. Amadivayisi we-Huawei ayakwazi ukukhiqiza imifudlana yendawo efika kweyishumi nambili, kuyilapho izindawo zokufinyelela ekugcineni ezivela kwabanye abakhiqizi zinesishiyagalombili kuphela.
2. Izindawo ezintsha zokufinyelela ze-Huawei ziyakwazi ukukhiqiza imifudlana eyisishiyagalombili yendawo enobubanzi obungu-160 MHz ngayinye, kuyilapho abathengisi abaqhudelanayo benemifudlana eyisishiyagalombili engu-80 MHz. Njengomphumela, kanye nohhafu noma ngisho izikhathi ezimbili ukuphakama kokusebenza kwezixazululo zethu kungenzeka kufezeke.
3. Ngokuqondene nesilinganiso sesignali nomsindo, ngenxa yokusetshenziswa kobuchwepheshe be-Smart Antenna, izindawo zethu zokufinyelela zibonisa ukubekezelela okukhulu kakhulu ukuphazamiseka nezinga eliphakeme kakhulu le-RSSI ekwamukelweni kweklayenti - okungenani okuphindwe kabili (ngo-3 dB) .

Ake sithole ukuthi umkhawulokudonsa uvelaphi, ovame ukukhonjiswa kuma-database. Esimweni sethu - 10,75 Gbit / s.

Ifomula yokubala ikhonjiswe emfanekisweni ongenhla. Ake sibone ukuthi yiziphi iziphindaphinda ezikuyo.

Eyokuqala inombolo yemisakazo yendawo (ku-2,4 GHz - kufika kwezine, ku-5 GHz - kufika ku-6). Eyesibili iyunithi ehlukaniswe ngesamba sobude besikhathi sophawu kanye nobude besikhawu sonogada ngokuhambisana nendinganiso esetshenzisiwe. Njengoba ku-Wi-Fi 12,8 ubude bophawu buphindwe kane kuya ku-0,8 μs, futhi isikhawu sonogada singu-1 μs, umphumela ngu-13,6/XNUMX μs.

Okulandelayo: njengesikhumbuzo, sibonga ukushintshwa kwe-1024-QAM okuthuthukisiwe, kufika kumabhithi ayi-10 manje angabhalwa ngekhodi ngophawu ngalunye. Sekukonke, sine-bitrate ka-5/6 (FEC) - isiphindaphinda sesine. Futhi eyesihlanu inombolo ye-subcarriers (amathoni).

Okokugcina, ukungeza ukusebenza okuphezulu kwe-2,4 kanye ne-5 GHz, sithola inani elimangalisayo lika-10,75 Gbps.

Ukuphathwa kwensiza yomsakazo we-DBS nakho kuvele ezindaweni zethu zokufinyelela nezilawuli. Uma ngaphambilini bekumele ukhethe ububanzi besiteshi se-SSID ethile kanye (20, 40 noma 80 MHz), manje kungenzeka ukuthi ulungiselele isilawuli ukuze senze lokhu ngamandla.

Enye intuthuko ekusatshalalisweni kwezinsiza zomsakazo ilethwe ubuchwepheshe beSmartRadio. Ngaphambilini, uma kwakukhona izindawo zokufinyelela eziningana endaweni eyodwa, kwakungenzeka ukucacisa ukuthi iyiphi i-algorithm yokusabalalisa kabusha amaklayenti, lapho i-AP ixhuma khona entsha, njll. Kodwa lezi zilungiselelo zisetshenziswe kanye kuphela, ngesikhathi sokuxhuma futhi. ukuxhumana nenethiwekhi ye-Wi-Fi. Endabeni ye-AirEngine, ama-algorithms okulinganisa umthwalo angasetshenziswa ngesikhathi sangempela ngenkathi amaklayenti esebenza futhi, isibonelo, ukuhamba phakathi kwezindawo zokufinyelela.

I-nuance ebalulekile ephathelene nezinto ze-antenna: kumamodeli we-AirEngine asebenzisa ngesikhathi esisodwa kokubili ukuhlukaniswa okuqondile nokuvundlile. Ngayinye isekela izimpondo ezine, futhi kunezinto ezine ezinjalo. Ngakho inani eliphelele - ama-antenna ayi-16.

I-elementi ye-antenna ngokwayo ayisebenzi. Ngakho-ke, ukuze ugxilise amandla amaningi ohlangothini lweklayenti, kuyadingeka ukwakha ugongolo oluncane usebenzisa ama-antenna ahlangene. UHuawei uphumelele. Umphumela uba ukusabalala komsakazo ngokwesilinganiso ngama-20% okukhulu kunaleyo yezixazululo ezincintisanayo.

Nge-Wi-Fi 6, i-ultra-high throughput kanye namazinga aphezulu okushintshashintsha (MCS 10 kanye ne-MCS 11 schemes) kungenzeka kuphela uma isilinganiso sesignali-kuya-noise, noma I-Signal-to-Noise Ratio, idlula u-35 dB. Wonke ama-decibel abalulekile. Futhi i-antenna ehlakaniphile ikuvumela ngempela ukuthi ukhuphule izinga lesiginali eyamukelwe.

Ezivivinyweni zangempela, ukuguqulwa kwe-1024-QAM ngohlelo lwe-MCS 10 kuzosebenza ebangeni elingeqile ku-3 m ukusuka endaweni yokufinyelela, noma yikuphi okutholakala emakethe. Yebo, uma usebenzisa i-antenna "ehlakaniphile", ibanga lingakhuphuka libe ngu-6-7 m.

Obunye ubuchwepheshe uHuawei abuhlanganise ezindaweni ezintsha zokufinyelela bubizwa ngeDynamic Turbo. Umongo wayo ulele eqinisweni lokuthi i-AP ingakwazi ukubona futhi ihlukanise izinhlelo zokusebenza endizeni ngekilasi (ngokwesibonelo, idlulisa ividiyo yesikhathi sangempela, ithrafikhi yezwi noma enye into), ihlukanise amaklayenti ngokwezinga lawo lokubaluleka futhi yabe amayunithi ezinsiza indlela enjalo yokuqinisekisa ukuthi izinhlelo zokusebenza ezisezingeni eliphezulu ezibalulekile kubasebenzisi zisebenza ngokushesha okukhulu. Eqinisweni, ezingeni le-hardware, indawo yokufinyelela yenza i-DPI - ukuhlaziywa kwethrafikhi ejulile.

Njengoba kuphawuliwe ekuqaleni, uHuawei njengamanje ukuphela komthengisi ohlinzeka ngokusebenza ngasikhathi sinye kwe-MU-MIMO ne-OFDMA ezisombululweni zayo. Ake sithathe imininingwane eyengeziwe mayelana nomehluko phakathi kwazo.

Bobabili ubuchwepheshe bakhelwe ukunikeza ukufinyelela kwabasebenzisi abaningi. Uma kunabasebenzisi abaningi kunethiwekhi, i-OFDMA ivumela insiza yemvamisa ukuthi isatshalaliswe ukuze amaklayenti amaningi athole futhi amukele ulwazi ngesikhathi esisodwa. Kodwa-ke, i-MU-MIMO ekugcineni ihlose into efanayo: lapho amaklayenti amaningana etholakala ezindaweni ezihlukene ekamelweni, ngalinye lingathunyelwa ukugeleza kwendawo okuyingqayizivele. Ukuze kucace, ake sicabange ukuthi insiza yemvamisa iyindlela yaseMoscow-St. I-OFDMA ibonakala iphakamisa: “Masingawenzi umzila owodwa, kodwa sibe mibili, ukuze usetshenziswe ngokuphumelelayo.” I-MU-MIMO inendlela ehlukile: "Ake sakhe umgwaqo wesibili, wesithathu ukuze izimoto zihambe ezindleleni ezizimele." Ngokwethiyori, eyodwa ayiphikisani nomunye, kodwa empeleni, inhlanganisela yezindlela ezimbili idinga isisekelo esithile se-algorithmic. Ngenxa yokuthi i-Huawei ikwazile ukudala lesi sisekelo, ukuphuma kwezindawo zethu zokufinyelela kukhuphuke cishe ngo-40% uma kuqhathaniswa nalokho izimbangi ezikwazi ukukunikeza.

Mayelana nokuvikeleka, izindawo ezintsha zokufinyelela, njengamamodeli wangaphambilini, zisekela i-DTLS. Lokhu kusho ukuthi, njengangaphambili, ithrafikhi yokulawula ye-CAPWAP ingabethelwa.

Ngokuvikeleka emathonyeni amabi angaphandle, yonke into iyafana neyasesizukulwaneni sangaphambili sabalawuli. Noma yiluphi uhlobo lokuhlasela, kungaba amandla anonya, ukuhlasela okubuthakathaka kwe-IV (ama-vector okuqalisa abuthakathaka) noma enye into, kutholwa ngesikhathi sangempela. Ukusabela ku-DDoS nakho kuyalungiseka: isistimu ingakha uhlu oluvinjelwe olunamandla, yazise umlawuli mayelana nokuthi kwenzakalani lapho izama ukuhlasela kwenethiwekhi esabalalisiwe, njll.

Yiziphi izixazululo ezihambisana namamodeli we-AirEngine

Inkundla yethu ye-CampusInsight Wi-Fi 6 analytics ixazulula izinkinga ezimbalwa. Okokuqala, isetshenziswa ekuphathweni komsakazo kanye nesilawuli: I-CampusInsight ikuvumela ukuthi wenze ukulinganisa futhi ngesikhathi sangempela usabalalise kahle amashaneli, ulungise amandla esiginali kanye nomkhawulokudonsa wesiteshi esithile, futhi ulawule ukuthi kwenzekani nge-Wi-Fi. inethiwekhi. Kukho konke lokho, i-CampusInsight iyasebenza nasekuvikelekeni okungenantambo (ikakhulukazi, ekuvimbeleni ukungena nokutholwa kokungena), futhi hhayi ngokuphathelene nendawo ethile yokufinyelela noma i-SSID eyodwa, kodwa esikalini sayo yonke ingqalasizinda engenantambo.

I-WLAN Planner nayo ikufanele ukunakwa - ithuluzi lokumodela umsakazo, futhi inganquma ngokuzimela ezinye izithiyo, njengezindonga. Ekuphumeni, uhlelo lukhiqiza umbiko omfushane, phakathi kwezinye izinto, obonisa ukuthi zingaki izindawo zokufinyelela ezidingekayo ukuze kuhlanganiswe igumbi. Ngokusekelwe kulokho okufakiwe, kulula kakhulu ukwenza izinqumo ezinolwazi oluthe xaxa mayelana nokucaciswa kwemishini, isabelomali, njll.

Phakathi kwesofthiwe, siphinde sisho Uhlelo Lokusebenza Lwekhampasi Yamafu, etholakala kuwo wonke umuntu kukho kokubili i-iOS ne-Android futhi equkethe isethi yonke yamathuluzi okuqapha inethiwekhi engenantambo. Ezinye zazo zenzelwe ukuhlola ikhwalithi ye-Wi-Fi (isibonelo, ukuhlola kokuzulazula). Phakathi kwezinye izinto, ungakwazi ukuhlola izinga lesignali, uthole imithombo yokuphazamiseka, hlola ukuphuma endaweni ethile, futhi uma kunezinkinga, thola izimbangela zabo.
