Yintoni enomdla malunga ne-Wi-Fi 6 nguHuawei

Sikuzisa ingqalelo yakho umbono kaHuawei weWi-Fi 6 - itekhnoloji ngokwayo kunye nezinto ezintsha ezihambelanayo, ngokuyintloko ngokumalunga neendawo zokufikelela: yintoni entsha ngabo, apho baya kufumana isicelo esifanelekileyo nesiluncedo ngo-2020, zeziphi izisombululo zetekhnoloji ezibanika zona. iinzuzo eziphambili zokukhuphisana kunye nendlela umgca we-AirEngine ulungelelaniswa ngayo ngokubanzi.

Kwenzeka ntoni kwiteknoloji engenazingcingo namhlanje

Ngethuba leminyaka xa izizukulwana zangaphambili ze-Wi-Fi - yesine neyesihlanu - ziphuhliswa, ingcamango yeofisi engenazintambo zonke, oko kukuthi, indawo yeofisi engenazintambo ngokupheleleyo, yenziwa kwishishini. Kodwa ukususela ngoko, amanzi amaninzi adlulile phantsi kwebhulorho, kwaye iimfuno zoshishino malunga ne-Wi-Fi zitshintshile ngokomgangatho kunye nobungakanani: iimfuno ze-bandwidth ziye zanda, ukunciphisa i-latency kuye kwaba yinto ebaluleke kakhulu, kwaye ngokuqhubekayo, ukunyanzelisa imfuno qhagamshela inani elikhulu labasebenzisi.

Ngo-2020, imbonakalo yomhlaba yezicelo ezitsha iye yavela ekufuneka isebenze ngokuthembekileyo kuthungelwano lwe-Wi-Fi. Lo mfanekiso ubonisa ezona nkalo ziphambili ezo zicelo zinxulumene nazo. Ngokufutshane malunga nabambalwa babo.

A. Augmented kunye nenyani virtual. Kwangexesha elide, izifinyezo ze-VR kunye ne-AR zivele kwiintetho zabathengisi be-telecom, kodwa bambalwa abantu abaqondayo ukuba yintoni ukusetyenziswa kobuchwephesha emva kwezi leta. Namhlanje bangena ngokukhawuleza ebomini bethu, ebonakaliswa kwiimveliso zeHuawei. Ngo-Epreli, sazisa iHuawei P40 i-smartphone kwaye kwangaxeshanye yaziswa - ukuza kuthi ga ngoku kuphela e-China-inkonzo yeemephu zeHuawei kunye nomsebenzi we-AR Maps. Akunjalo nje "i-GIS enehologram". Inyaniso eyongeziweyo yakhiwe ngokunzulu ekusebenzeni kwenkqubo: ngoncedo lwayo, akubizi nto "ukubamba" ngokoqobo ulwazi malunga nombutho othile oofisi yakhe ibekwe kwisakhiwo, iceba indlela kwindawo ejikelezileyo - kwaye konke oku kwi-3D ifomathi kunye nowona mgangatho uphezulu.

Ngokuqinisekileyo i-AR iya kubona uphuhliso olumandla kwiinkalo zemfundo kunye nokhathalelo lwempilo. Kukwafanelekile kwimveliso: umzekelo, ukwenzela ukuqeqesha abasebenzi ukuba benze njani kwiimeko ezingxamisekileyo, kunzima ukuza nento engcono kunama-simulators kwinyani eyandisiweyo.

B. Iinkqubo zokhuseleko kunye nokucupha ividiyo. Kwaye ngokubanzi: nasiphi na isisombululo sevidiyo esihlangabezana nemigangatho yenkcazo ephezulu kakhulu. Asithethi nge-4K kuphela, kodwa kunye ne-8K. Abavelisi abaphambili koomabonwakude kunye neephaneli zolwazi bathembisa ukuba iimodeli ezivelisa imifanekiso ye-8K UHD ziya kuvela kuluhlu lweemveliso zabo ngo-2020. Kusengqiqweni ukucinga ukuba abasebenzisi bokugqibela baya kufuna ukubukela iividiyo ezikumgangatho ophezulu kakhulu ngebitrate eyandisiweyo.

B. Ushishino oluthe nkqo, kwaye okokuqala kuyo yonke intengiso. Makhe sithathe umzekelo I-Lidl -enye yeevenkile ezinkulu ezinkulu eYurophu. Usebenzisa iWi-Fi entsha, ngokusekelwe kwi-IoT iimeko zokusebenzisana nabathengi, ngokukodwa, yazisa iithegi zexabiso ze-elektroniki ze-ESL, ezidibanisa neCRM yayo.

Ngokubhekiselele kwimveliso emikhulu, amava eVolkswagen ayaphawuleka, asebenzise i-Wi-Fi evela kwiHuawei kwiifektri zayo kwaye iyisebenzisela ukusombulula iingxaki ezahlukeneyo. Phakathi kwezinye izinto, inkampani ixhomekeke kwi-Wi-Fi 6 ukusebenzisa iirobhothi ezihamba ngeenxa zonke kwifektri, i-scan parts ngexesha langempela usebenzisa iimeko ze-AR, njl.

G. "Iiofisi ezihlakaniphileyo" kwakhona imele indawo enkulu yezinto ezintsha ezisekelwe kwi-Wi-Fi 6. Inani elikhulu lezinto ze-Intanethi ze-Intanethi "zesakhiwo esihlakaniphile" sele sele sicatshangelwe, kubandakanywa nokulawula ukhuseleko, ukulawula ukukhanya, njl.

Akumele silibale ukuba uninzi lwezicelo lufudukela efini, kwaye ukufikelela kwilifu kufuna umgangatho ophezulu, uqhagamshelo oluzinzileyo. Kungenxa yoko le nto uHuawei esebenzisa isaci kwaye ezabalazela ukuphumeza injongo "ye-100 Mbps kuyo yonke indawo": I-Wi-Fi iba yeyona ndlela iphambili yokuqhagamshela kwi-Intanethi, kwaye nokuba ithini na indawo yomsebenzisi, sinyanzelekile ukuba simnike indawo ephezulu. inqanaba lamava omsebenzisi.

Uceba uHuawei ukulawula iWi-Fi 6 yakho

Okwangoku, iHuawei iphakamisa isisombululo se-Cloud Campus esele ilungile, ejolise, kwelinye icala, ekuncedeni ukulawula yonke isiseko selifu, kwaye kwelinye icala, ekusebenzeni njengeqonga lokuphumeza okutsha. Iimeko ze-IoT, nokuba kulawulo lwezakhiwo, ukubeka iliso kwezixhobo okanye, umzekelo, ukuba siphendulela kwimeko evela kwintsimi yeyeza, ukubeka iliso kwiiparamitha ezibalulekileyo zesigulane.

Inxalenye ebalulekileyo ye-ecosystem ejikeleze i-Cloud Campus yindawo yentengiso. Ngokomzekelo, ukuba umphuhlisi udale isixhobo sokugqibela kwaye wasidibanisa kunye nezisombululo zeHuawei ngokubhala isofthiwe efanelekileyo, unelungelo lokwenza imveliso yakhe ifumaneke kwabanye abathengi bethu usebenzisa imodeli yenkonzo.

Kuba inethiwekhi ye-Wi-Fi iba sisiseko sokusebenza kweshishini, iindlela zakudala zokuyilawula azonelanga. Ngaphambili, umlawuli wanyanzeliswa ukuba acinge ukuba kuqhubeka ntoni ngenethiwekhi phantse ngesandla, ukumba izigodo. Le ndlela isebenzayo yenkxaso ngoku inqabile. Izixhobo ziyafuneka ekubekeni iliso okukhawulezileyo kunye nolawulo lweziseko zoncedo ezingenazingcingo ukuze umlawuli aqonde ngqo ukuba kwenzeka ntoni kuyo: leliphi inqanaba lamava omsebenzisi elibonelelayo, nokuba ngaba abasebenzisi abatsha banokuqhagamshela kuyo ngaphandle kweengxaki, nokuba ngaba kukho nabaphi na abathengi abafuna ukuba "idluliselwe" kwindawo yokufikelela engummelwane (AP), yintoni na i-node nganye yenethiwekhi ekhoyo, njl.

Kwizixhobo ze-Wi-Fi ezi-6, iHuawei inazo zonke izixhobo zokuqhuba, ukuhlalutya nzulu kunye nokulawula okwenzekayo kwinethiwekhi. Olu phuhliso lusekwe ikakhulu kwi-algorithms yokufunda koomatshini.

Oku kwakungenakwenzeka kwiindawo zokufikelela kuchungechunge lwangaphambili, ekubeni abazange baxhase iiprothokholi ze-telemetry ezifanelekileyo, kwaye ngokubanzi ukusebenza kwezo zixhobo akuzange kuvumele ukuba lo msebenzi uphunyezwe ngendlela apho iindawo zethu zokufikelela zanamhlanje zivumela.

Ziziphi iingenelo zomgangatho we-Wi-Fi 6

Kwangexesha elide, isikhubekiso ekusasazeni i-Wi-Fi 6 yahlala iyinyani yokuba bekukho de facto akukho zixhobo zokuphela eziza kuxhasa umgangatho we-IEEE 802.11ax kwaye unokuqonda ngokupheleleyo inzuzo ekhoyo kwindawo yokufikelela. Nangona kunjalo, ukuguquka kwenzeka kwishishini, kwaye thina, njengomthengisi, sinegalelo kuwo ngamandla ethu onke: IHuawei iphuhlise i-chipsets yayo kungekuphela nje kwiimveliso zenkampani, kodwa kunye nezixhobo zeselula kunye nekhaya.

- Ulwazi malunga ne-Wi-Fi 6+ evela kwiHuawei ijikeleza kwi-Intanethi. Yintoni lento?
- Iphantse yafana ne-Wi-Fi 6E. Yonke into iyafana, kuphela ngokongezwa koluhlu lwe-6 GHz. Amazwe amaninzi ngoku acinga ukuyenza ifumaneke kwi-Wi-Fi 6.

- Ngaba i-interface yerediyo ye-6 GHz iya kuphunyezwa kwimodyuli efanayo ngoku isebenza kwi-5 GHz?
- Hayi, kuya kubakho ii-eriyali ezikhethekileyo zokusebenza kwi-6 GHz frequency range. Iindawo zofikelelo zangoku azixhasi i-6 GHz, nokuba isoftware yazo ihlaziywe.

Namhlanje, izixhobo eziboniswe kulo mzekeliso ziyinxalenye ye-hi-end. Ngelo xesha, i-router ye-Huawei AX3 yasekhaya, ebonelela ngesantya ukuya kwi-2 Gbit / s nge-interfaces yomoya, ayifani nexabiso ukusuka kwiindawo zokufikelela kwisizukulwana sangaphambili. Ke ngoko, kukho zonke izizathu zokukholelwa ukuba ngo-2020, uluhlu olubanzi lomgangatho ophakathi kunye nezixhobo zokungena ziya kufumana inkxaso ye-Wi-Fi 6 ngokwezibalo zikaHuawei. ngo-2022, ukuthengiswa kweendawo zokufikelela ezixhasa i-Wi-Fi 6 xa kuthelekiswa nezo zakhiwe kwi-Wi-Fi 5 ziya kuba yi-90 ukuya kwi-10%.

Kunyaka onesiqingatha, ixesha le-Wi-Fi 6 liya kufika ekugqibeleni.

Okokuqala, i-Wi-Fi 6 yenzelwe ukwenza inethiwekhi engasebenzi ngeengcingo isebenze ngakumbi. Ngaphambili, isitishi ngasinye sanikwa ixesha elilandelelanayo kwaye sahlala kulo lonke ijelo le-20 MHz, linyanzela abanye ukuba balinde ukuba lithumele itrafikhi. Ngoku ezi 20 MHz zisikwe zibe zincinci ezincinci, zidityaniswe kwiiyunithi zemithombo, ukuya kuthi ga kwi-2 MHz, kwaye ukuya kuthi ga kwizikhululo ezisithoba zinokusasaza ngaxeshanye ngexesha elinye. Oku kubangela ukwanda okukhulu ekusebenzeni kwenethiwekhi yonke.

Sele sitshilo ukuba izikimu zokumodareyitha eziphezulu zongezwa kumgangatho wesithandathu wesizukulwana: 1024-QAM ngokubhekiselele kwi-256 yangaphambili. Ubunzima be-encoding ngoko bonyuka nge-25%: ukuba ngaphambili sasihambisa ukuya kwii-bits ze-8 zolwazi ngomlingisi, ngoku amasuntswana ali-10.

Inani lemisinga yendawo nalo liye landa. Kwimigangatho yangaphambili bekukho ubuninzi besine, ngelixa ngoku kukho ukuya kuthi ga kwisibhozo, kwaye kwiindawo ezidala zokufikelela kwiHuawei ukuya kwishumi elinesibini.

Ukongeza, i-Wi-Fi 6 iphinda isebenzise uluhlu lwamaza e-2,4 GHz, okwenza kube lula ukuvelisa i-chipsets ngexabiso eliphantsi kwiitheminali zokuphela ezixhasa i-Wi-Fi 6 kwaye ziqhagamshele inani elikhulu lezixhobo, nokuba ziimodyuli ze-IoT ezigcweleyo okanye ezinye kakhulu. abenzi boluvo batshiphu

Eyona nto ibalulekileyo kukuba umgangatho uphumeza iitekhnoloji ezininzi zokusetyenziswa ngokukuko kwerediyo, kubandakanywa ukusetyenziswa kwakhona kweetshaneli kunye neefrikhwensi. Okokuqala, i-Basic Service Set (BSS) Umbala ufanelekile ukukhankanywa, okuvumela ukuba ungahoyi iindawo zokufikelela zabanye abantu ezisebenza kwisitishi esifanayo, kwaye kwangaxeshanye "uphulaphule" eyakho.

Ziziphi iindawo zokufikelela kwi-Wi-Fi 6 ezivela kwiHuawei esicinga ukuba kufuneka zenziwe kuqala?

Imifanekiso ibonisa iindawo zokufikelela ezinikezelwa nguHuawei namhlanje kwaye, okona kubaluleke kakhulu, eziza kuqala ukubonelela, ngokuqala ngesiseko se-AirEngine 5760 imodeli kunye nokuphela kweziphezulu.

Amanqaku ethu okufikelela axhasa umgangatho we-802.11ax aphumeza uluhlu olupheleleyo lwezisombululo ezizodwa zobuchwepheshe.

• Ukufumaneka kwemodyuli ye-IoT eyakhelwe-ngaphakathi okanye ukukwazi ukudibanisa yangaphandle. Kuzo zonke iindawo zokufikelela, ikhava ephezulu ngoku iyavula, kwaye ngaphantsi kwayo kufihlwe iindawo ezimbini zokubeka iimodyuli ze-IoT, phantse naluphi na uhlobo. Ngokomzekelo, ukusuka kwi-ZigBee, ilungele ukudibanisa iisokethi ezihlakaniphile okanye i-relays, i-telemetry sensors, njl njl. Hantshow). Ngaphezu koko, ezinye iindawo zokufikelela kuthotho zinesixhobo esongezelelweyo se-USB, kwaye imodyuli ye-Intanethi yeZinto inokudityaniswa ngayo.
• Isizukulwana esitsha sobuchwepheshe be-Smart Antenna. Indawo yokungena inezindlu ukuya kutsho kwi-eriyali ezili-16, zenza imijelo efikelela kwi-12. Ezo "eriyali ezikrelekrele" zenza ukuba kwenzeke, ngakumbi, ukunyusa irediyasi yokugubungela (kwaye ulahle "imimandla efileyo") ngenxa yokuba nganye kuzo inoluhlu olugxilileyo losasazo lwerediyo kwaye "iyaqonda" apho indawo yendawo ibekwe ngexesha elinye okanye omnye umxhasi.
• Iradiyasi enkulu yosasazo yomqondiso kuthetha ukuba i-RSSI yomthengi, okanye inqanaba lesignali yokwamkela, nayo iya kuba phezulu. Kwiimvavanyo ezithelekisayo, xa indawo yokufikelela rhoqo ye-omni-directional kunye neyodwa ixhotyiswe ngee-antenna ezihlakaniphile zivavanywa, okwesibini kunokunyuka kwamandla kabini-i-3 dB eyongezelelweyo.

Xa usebenzisa i-eriyali ezihlakaniphile, akukho mqondiso we-asymmetry, ekubeni uvakalelo lwendawo yokufikelela lukhula ngokulinganayo. I-antenna nganye ye-16 isebenza njengesibuko: ngenxa yomgaqo wokusasazwa kwezinto ezininzi, xa umxhasi ethumela i-beam yolwazi, i-radio wave ehambelanayo, ebonakaliswe kwimiqobo eyahlukeneyo, ibetha zonke ii-antenna ezili-16. Emva koko inqaku, usebenzisa i-algorithms yangaphakathi, yongeza izibonakaliso ezifunyenweyo kwaye ibuyisela idatha ekhowudiweyo ngeqondo elikhulu lokuthembeka.

• Zonke iindawo ezintsha zokufikelela kwiHuawei ziphunyezwa SDR (Software-Defined Radio) ubuchwepheshe. Enkosi kuyo, ngokuxhomekeke kwimeko ekhethiweyo yokusebenza kweziseko ezingundoqo ezingenazingcingo, umlawuli umisela ukuba iimodyuli ezintathu zikanomathotholo kufuneka zisebenze njani. Mingaphi imijelo yesithuba eya kwabelwa enye okanye enye ikwamiselwa ngokuguquguqukayo. Umzekelo, unokwenza iimodyuli ezimbini zikanomathotholo zisebenze ukudibanisa abathengi (enye kuluhlu lwe-2,4 GHz, enye kuluhlu lwe-5 GHz), kwaye eyesithathu isebenza njengeskena, esweni ukuba kwenzeka ntoni kwimeko yerediyo. Okanye sebenzisa iimodyuli ezintathu kuphela ukudibanisa abathengi.

  Enye imeko eqhelekileyo xa kungekho baninzi abathengi kwinethiwekhi, kodwa izixhobo zabo ziqhuba izicelo eziphezulu ezifuna i-bandwidth ephezulu. Kule meko, yonke imijelo yendawo ibotshelelwe kuluhlu lwe-frequency ye-2,4 kunye ne-5 GHz, kwaye iziteshi ziyadityaniswa ukubonelela abasebenzisi nge-20, kodwa i-80 MHz bandwidth.

• Iindawo zofikelelo ziyaphunyezwa izihluzi ngokwemigaqo ye3GPP, ukuze kwahlule iimodyuli zikanomathotholo ezinokuthi zisebenze kwiifrikhwensi ezahlukeneyo kuluhlu lwe-5 GHz ukusuka kwenye, ukunqanda ukuphazamiseka kwangaphakathi.

Iindawo zokufikelela zibonelela ngokusebenza ngeendlela ezahlukeneyo. Enye yazo yi-RTU (Ilungelo lokuSebenzisa). Ngokufutshane, umgaqo wayo osisiseko umi ngolu hlobo lulandelayo. Iimodeli zoluhlu ngalunye ziya kubonelelwa ngenguqu eqhelekileyo, umzekelo ngemijelo emithandathu yendawo. Ngaphaya koko, ngoncedo lwelayisenisi, kuya kwenzeka ukwandisa ukusebenza kwesixhobo kwaye kusebenze imijelo emibini eyongezelelweyo, ukuveza i-hardware enokubakho kuyo. Enye inketho: mhlawumbi, ekuhambeni kwexesha, umxhasi uya kufuna ukwabela i-interface eyongezelelweyo yerediyo yokuskena i-airwaves, kwaye ukuze uyibeke ekusebenzeni, kuya kukwanela ukuthenga ilayisenisi kwakhona.

Kwicandelo elisezantsi lasekunene lomzobo wangaphambili, iindawo zokufikelela zineembalelwano zedijithali, umzekelo 2 + 2 + 4 ngokumalunga ne-AirEngine 5760. Ingongoma kukuba i-AP ineemodyuli ezintathu zomsakazo ezizimeleyo. Amanani abonisa ukuba mangaphi amajelo omhlaba aya kwabelwa imodyuli yerediyo nganye. Ngokufanelekileyo, inani lemisonto lichaphazela ngokuthe ngqo i-throughput kuluhlu olunikiweyo. Uluhlu olusemgangathweni lubonelela ukuya kuthi ga kwimijelo esibhozo. Ukuqhubela phambili - ukuya kuthi ga kwi-12. Ekugqibeleni, i-flagship (izixhobo ze-hi-end) - ukuya kwi-16.

Usebenza njani umgca we-AirEngine

Ukusukela ngoku, uphawu oluqhelekileyo lwezisombululo ezingenazingcingo zenkampani yiAirEngine. Njengoko unokubona ngokulula, uyilo lweendawo zofikelelo luphefumlelwe ziiinjini zeenjini zenqwelomoya: ii-diffusers ezikhethekileyo zibekwe kwindawo yangaphambili nasemva kwezixhobo.

Uchungechunge lokuqala lwe-AirEngine 5760-51 izixhobo zezona zifikeleleke kubathengi kwaye zenzelwe iimeko eziqhelekileyo. Umzekelo, ukuthengisa. Nangona kunjalo, zifanelekile kwiimfuno zeofisi, kuba zizonke malunga ne-teknoloji esetyenzisiweyo kunye neendleko.

Uluhlu olulandelayo oludala luyi-5760-22W. Iquka iindawo zokufikelela kwiplate eludongeni, ezinganqunyanyiswa kwisilingi, kodwa zibekwe etafileni, ekhoneni okanye zifakwe eludongeni. Zifaneleke kakhulu kwezo meko apho kuyimfuneko ukugubungela inani elikhulu lamagumbi amancinci kunye nonxibelelwano olungenacingo (esikolweni, esibhedlele, njl.), apho kufuneka uqhagamshelo lweengcingo.

Imodeli ye-5760-22W (i-wall-plate) inika uxhulumaniso lwe-2,5 Gbit / s ngokusebenzisa i-interfaces zethusi, kwaye ine-transceiver ekhethekileyo ye-SFP ye-PON. Ngaloo ndlela, uluhlu lokufikelela lunokuphunyezwa ngokupheleleyo kwinethiwekhi ye-optical passive kwaye indawo yokufikelela inokudibaniswa ngokuthe ngqo kule nethiwekhi ye-GPON.

Uluhlu lubandakanya zombini iindawo zokufikelela zangaphakathi nangaphandle. Aba bamva bahluke ngokulula ngonobumba R (ngaphandle) egameni. Ngaloo ndlela, i-AirEngine 8760-X1-PRO yenzelwe ukusetyenziswa kwangaphakathi, ngelixa i-AirEngine 8760R-X1 yenzelwe iimeko zangaphandle. Ukuba igama lendawo yokufikelela iqulethe ileta E (yangaphandle), ithetha ukuba ii-antenna zayo azakhelwanga, kodwa zingaphandle.

Imodeli ephezulu - i-AirEngine 8760-X1-PRO ixhotyiswe nge-interfaces ezintathu zegigabit ezilishumi zokudibanisa. Ezimbini zazo zibhedu, kwaye zombini zixhasa i-PoE / PoE-IN, ekuvumela ukuba ugcine isixhobo samandla. Eyesithathu yeyonxibelelwano lwefiber optic (SFP+). Ukucaca, olu lunxibelelwano lwe-combo: uqhagamshelo ngobhedu kunye ne-optical lunokwenzeka. Kwakhona, masithi, akukho nto ikuthintela ukuba udibanise indawo yokufikelela nge-optics, kunye nokubonelela ngamandla kwi-injector nge-interface yobhedu. Kufuneka kwakhona sikhankanye i-Bluetooth 5.0 port eyakhelwe-ngaphakathi. I-8760-X1-PRO inomsebenzi ophezulu kakhulu kumgca, kuba ixhasa ukuya kwi-16 imilambo yendawo.

— Ngaba iindawo zofikelelo zePoE + zinamandla awoneleyo?
- Kuluhlu oludala (8760) i-POE ++ iyafuneka. Kungenxa yoko le nto i-CloudEngine s5732 itshintsha kunye ne-multi-gigabit port kunye nenkxaso ye-802.3bt (ukuya kwi-60 W) iya kuthengiswa ngoMeyi-Juni.

Ngaphezu koko, i-AirEngine 8760-X1-PRO ifumana ukupholisa okongeziweyo. Ulwelo lujikeleza ngeesekethe ezimbini ngaphakathi kwendawo yokufikelela, isusa ubushushu obugqithisileyo kwi-chipset. Esi sisombululo silungiselelwe ngokuyinhloko ukuqinisekisa ukusebenza kwexesha elide lesixhobo kunye nokusebenza okuphezulu: abanye abathengisi bavakalisa ukuba iindawo zabo zokufikelela nazo ziyakwazi ukuhambisa ukuya kwi-10 Gbps, nangona kunjalo, emva kwemizuzu eyi-15-20 ezi zixhobo zilungele ukufudumala, kwaye ngenxa yokunciphisa ubushushu babo, inxalenye yendawo yokuhamba iyacinywa, enciphisa ukuphuma.

Amanqaku asezantsi okufikelela kwiichungechunge azikho ukupholisa ulwelo, kodwa abanayo ingxaki yokufudumeza ngenxa yokusebenza okuphantsi. Iimodeli zomgangatho ophakathi-i-AirEngine 6760-ixhasa ukuya kuthi ga kwimijelo ye-12 yendawo. Bakwadibanisa nge-interface yegigabit ezilishumi. Ukongeza, kukho i-gigabit enye - ukuxhuma kwiiswitshi ezikhoyo.

UHuawei ebebonelela ngesisombululo ixesha elide I-Agile isasazwe nge-Wi-Fi, oku kuthetha ubukho bendawo yofikelelo esembindini kunye neemodyuli zerediyo ezikude ezilawulwa yiyo. I-AP enjalo inoxanduva lweentlobo ezahlukeneyo zemisebenzi yomthwalo ophezulu kwaye ixhotyiswe nge-CPU ukuphumeza i-QoS, yenza izigqibo malunga nokuzulazula kwabathengi, umda we-bandwidth, ukuqaphela izicelo, njl. Emva koko, iimodyuli zerediyo zangaphandle ngokwenene zithumela i-traffic kwifom yayo yokuqala. ukuya kwindawo yofikelelo esembindini kwaye wenze abaguquli ukusuka ku-802.11 ukuya ku-802.3.

Isigqibo savela ukuba asithandwa kakhulu eRashiya. Noko ke, ubani akanakusilela ukuphawula iingenelo zayo. Umzekelo, kunokwenzeka ukuba ulondoloze kakhulu kwiindleko zeelayisenisi, kuba akuyomfuneko ukuba uthenge eyahlukileyo kwimodyuli yerediyo nganye. Ukongeza, umthwalo oyintloko uwela kwiindawo zokufikelela ezisembindini, okwenza kube lula ukuhambisa inethiwekhi enkulu engenazingcingo equkethe amashumi amawaka ezinto. Ke ngoko sihlaziye i-Agile Distributed Wi-Fi ukuze sithathe ithuba lobuchwephesha bethu obujikeleze i-Wi-Fi 6.

Iindawo zokungena ngaphandle nazo ziya kufumaneka ngoJuni. Uluhlu oluphezulu phakathi kwezixhobo zangaphandle yi-8760R, kunye ne-teknoloji ephezulu ye-stack (ngokukodwa, ukuya kuthi ga kwi-16 imilambo yendawo ekhoyo). Nangona kunjalo, sicinga ukuba kwiimeko ezininzi i-6760R iya kuba lolona khetho lufanelekileyo. Ukhuseleko lwasesitalatweni, njengomthetho, luyafuneka nokuba kukwiindawo zokugcina iimpahla, okanye kwiibhulorho ezingenazingcingo, okanye kwiindawo zobuchwepheshe, apho ngamaxesha athile kukho imfuneko yokufumana okanye ukusasaza i-telemetry okanye ukuqokelela ulwazi kwiitheminali zokuqokelela idatha.

Malunga neenzuzo zobuchwepheshe beendawo zokufikelela kwi-AirEngine

Ngaphambili, ukuguquguquka kwee-eriyali zangaphandle kwiindawo zethu zokufikelela kwakulinganiselwe kakhulu. Bekukho ii-eriyali ze-omni-directional (dipole), okanye ezimxinwa kakhulu. Ngoku ukhetho lubanzi. Umzekelo, i-eriyali engu-70 ° / 70 ° kwi-azimuth kunye nokuphakama kwabona ukukhanya. Ngokuyibeka ekhoneni legumbi, unokugubungela phantse yonke indawo phambi kwayo ngomqondiso.

Uluhlu lwee-antenna ezibonelelwa ngeendawo zokufikelela zangaphakathi zikhula, kwaye kunokwenzeka ukuba ngaphezulu kuya kongezwa, kubandakanywa nezo ziveliswa ngabanye abavelisi. Masenze ugcino: akukho zithe ngqo phakathi kwazo. Ukuba ufuna ukuququzelela ujoliso olujongiwe ngaphakathi, kuya kufuneka usebenzise iimodeli ezineeriyali ze-dipole zangaphandle kwaye uzibeke ngokwakho ukuze usasazeke kakhulu umqondiso werediyo, okanye uthathe iindawo zofikelelo ngee-eriyali ezakhelwe ngaphakathi.

Akukho tshintsho lubalulekileyo malunga nokufakelwa kweendawo zokufikelela. Zonke iimodeli zixhotyiswe ngezinto zokuqinisa ukunyuswa kokubini kwisilingi kunye nodonga okanye nakwipayipi (i-metal clamps). Izibophelelo nazo zifanelekile kwiisilingi zeofisi kunye nohlobo lwe-Armstrong yophahla lwe-roof rails. Ukongezelela, unokufakela izitshixo, okubaluleke ngakumbi ukuba indawo yokufikelela iya kusebenza kwindawo yoluntu.

Ukuba sijonga ngokukhawuleza kwizinto eziphambili zeteknoloji eziye zaphunyezwa ngexesha lokuphuhliswa koluhlu lwemodeli Injini yomoya, ufumana uluhlu olunje.

• Eyona mveliso iphezulu kushishino iphunyeziwe. Ukuza kuthi ga ngoku, iHuawei kuphela ikwazile ukuphumeza ii-antenna ze-16 zokufumana kunye nokuhambisa kunye nemijelo ye-12 yendawo kwindawo enye yokufikelela. Itekhnoloji ye-antenna ye-Smart ngendlela ephunyezwe ngayo yiHuawei ayifumaneki nakweyiphi na enye inkampani okwangoku.
• IHuawei inezisombululo ezikhethekileyo zokufezekisa i-latency ephantsi kakhulu. Oku kuvumela, ngakumbi, ukuzulazula okungenamthungo ngokupheleleyo kwiirobhothi zokugcina iimpahla.
• Njengoko usazi, itekhnoloji ye-Wi-Fi 6 ibandakanya izisombululo ezibini zofikelelo oluninzi: I-OFDMA kunye ne-Multi-User MIMO. Akukho mntu ngaphandle kweHuawei osele ekwazile ukuququzelela ukusebenza kwabo ngaxeshanye.
• Inkxaso ye-Intanethi yeZinto kwiindawo zokufikelela kwi-AirEngine ibanzi ngendlela engazange ibonwe ngaphambili kwaye iyinzalelwane.
• Umgca udibana nemigangatho ephezulu yokhuseleko. Ngaloo ndlela, onke amanqaku ethu e-Wi-Fi 6 asebenzisa ukubethelwa ngokusekelwe kwiprotocol yeWPA3.

Yintoni emisela i-throughput yendawo yokufikelela? Ngokutsho kwethiyori kaShannon, kwizinto ezintathu:

• kwinani lemilambo yendawo;
• kwi-bandwidth;
• kumlinganiselo wesignali ukuya kwingxolo.

Izisombululo zeHuawei kwindawo nganye kwezi zintathu zibizwa zihluke koko abanye abathengisi banikezelayo, kwaye nganye iqulethe uphuculo oluninzi.

1. Izixhobo zeHuawei ziyakwazi ukuvelisa imijelo yendawo ukuya kuthi ga kwishumi elinesibini, ngelixa iindawo zofikelelo eziphezulu ezivela kwabanye abavelisi zinesibhozo kuphela.
2. Amanqaku amatsha okufikelela eHuawei ayakwazi ukuvelisa imijelo esibhozo yendawo kunye nobubanzi be-160 MHz nganye, ngelixa abathengisi abakhuphisanayo banobuninzi bemijelo esibhozo ye-80 MHz. Ngenxa yoko, isinye nesiqingatha okanye amaxesha amabini ukongama kwezisombululo zethu kunokwenzeka.
3. Ngokubhekiselele kwi-signal-to-noise ratio, ngenxa yokusetyenziswa kwethekhnoloji ye-Smart Antenna, iindawo zethu zokufikelela zibonisa ukunyamezela okukhulu kakhulu ekuphazamisekeni kunye nenqanaba eliphezulu le-RSSI kwindawo yokwamkela umxhasi - ubuncinane kabini (nge-3 dB) .

Masibone ukuba i-bandwidth ivela phi, edla ngokuboniswa kwii-database. Kwimeko yethu - 10,75 Gbit / s.

Ifomula yokubala iboniswe kumzobo ongentla. Makhe sibone ukuba yintoni na iziphindaphindi kuyo.

Eyokuqala linani lemijelo yendawo (kwi-2,4 GHz - ukuya kwezine, kwi-5 GHz - ukuya kwisibhozo). Eyesibini yiyunithi eyahlulahlulwe ngesambuku sobude besimboli kunye nobude besithuba somlindi ngokungqinelana nomgangatho osetyenzisiweyo. Ekubeni kwi-Wi-Fi 6 ubude besimboli buphindwe kane ukuya kwi-12,8 μs, kwaye ikhefu lokulinda li-0,8 μs, umphumo ngu-1/13,6 μs.

Okulandelayo: njengesikhumbuzo, enkosi kuphuculo lokumodareyitha kwe-1024-QAM, ukuya kuthi ga kwiibhithi ezili-10 ngoku kunokufakwa ngekhowudi kwisimboli ngasinye. Lilonke, sine-bitrate ye-5/6 (FEC) - i-multiplier yesine. Kwaye okwesihlanu linani le-subcarriers (iithoni).

Ekugqibeleni, ukongeza ukusebenza okuphezulu kwe-2,4 kunye ne-5 GHz, sifumana ixabiso elimangalisayo le-10,75 Gbps.

Ulawulo lwemithombo yerediyo ye-DBS nayo ibonakala kwiindawo zethu zofikelelo kunye nabalawuli. Ukuba ngaphambili bekufuneka ukhethe ububanzi betshaneli ye-SSID ethile kanye (20, 40 okanye 80 MHz), ngoku kuyenzeka ukuba uqwalasele umlawuli ukuze enze oku ngamandla.

Olunye uphuculo ekuhanjisweni kwemithombo yerediyo yaziswa bubuchwepheshe be-SmartRadio. Ngaphambili, ukuba kukho iindawo ezininzi zokufikelela kwindawo enye, kwakunokwenzeka ukucacisa ukuba yeyiphi i-algorithm yokusabalalisa kwakhona abathengi, apho i-AP idibanisa entsha, njl. unxulumano nenethiwekhi ye-Wi-Fi. Kwimeko ye-AirEngine, i-algorithms yokulinganisa umthwalo ingasetyenziswa ngexesha langempela ngelixa abathengi basebenza kwaye, umzekelo, ukuhamba phakathi kweendawo zokufikelela.

I-nuance ebalulekileyo malunga nezinto ze-antenna: kwiimodeli ze-AirEngine zizalisekisa ngaxeshanye zombini i-polarization ethe nkqo kunye nethe tyaba. Nganye ixhasa ii-eriyali ezine, kwaye kukho izinto ezine ezinjalo. Ngenxa yoko inani elipheleleyo - i-antenna ezili-16.

Isiqalelo se-eriyali ngokwaso sisenziwa. Ngako oko, ukwenzela ukuba kugxininise amandla amaninzi kwicala lomthengi, kuyimfuneko ukwenza umqadi omncinci usebenzisa i-antennas edibeneyo. UHuawei uphumelele. Isiphumo sisasazo lukanomathotholo olukwi-avareji yama-20% enkulu kunolo lwezisombululo ezikhuphisanayo.

Nge-Wi-Fi 6, i-ultra-high throughput kunye namanqanaba aphezulu okumodareyitha (ii-MCS 10 kunye ne-MCS 11 schemes) zinokwenzeka kuphela xa umlinganiselo we-signal-to-noise ratio, okanye i-Signal-to-Noise Ratio, idlula i-35 dB. Yonke idecibel ibala. Kwaye i-antenna ehlakaniphile ikuvumela ngokwenene ukuba unyuse umgangatho wesignali efunyenweyo.

Kwiimvavanyo zangempela, ukumodareyitha kwe-1024-QAM kunye neskimu se-MCS 10 kuya kusebenza kumgama ongekho ngaphezu kwe-3 m ukusuka kwindawo yokufikelela, nayiphi na into ekhoyo kwimarike. Ewe, xa usebenzisa i-antenna "ehlakaniphile", umgama unokunyuswa ube ngu-6-7 m.

Obunye ubuchwephesha obudityaniswe nguHuawei kwiindawo ezintsha zokufikelela bubizwa ngokuba yiDynamic Turbo. Undoqo wayo ulele kwinto yokuba i-AP inokubona kwaye ihlele izicelo kwimpukane ngeklasi (umzekelo, ithumela ividiyo yexesha lokwenyani, i-traffic traffic okanye enye into), yahlula abathengi ngokwenqanaba labo lokubaluleka kwaye yabele iiyunithi zezibonelelo kwi. indlela enjalo yokuqinisekisa ukuba izicelo eziphezulu ezibalulekileyo kubasebenzisi zisebenza ngokukhawuleza. Enyanisweni, kwinqanaba le-hardware, indawo yokufikelela yenza i-DPI - uhlalutyo olunzulu lwe-traffic.

Njengoko kuphawuliwe ngaphambili, iHuawei ngoku kuphela komthengisi obonelela ngokusebenza ngaxeshanye kwe-MU-MIMO kunye ne-OFDMA kwizisombululo zayo. Masithathe iinkcukacha ezithe chatha malunga nomahluko phakathi kwazo.

Zombini itekhnoloji yenzelwe ukunika ukufikelela kubasebenzisi abaninzi. Xa kukho abasebenzisi abaninzi kuthungelwano, i-OFDMA ivumela isibonelelo samaxesha ukuba sisasazwe ukuze abathengi abaninzi bafumane kwaye bafumane ulwazi ngaxeshanye. Nangona kunjalo, i-MU-MIMO ekugqibeleni ijolise kwinto enye: xa abathengi abaninzi bebekwe kwiindawo ezahlukeneyo kwigumbi, ngamnye kubo unokuthunyelwa umjelo okhethekileyo wendawo. Ukucaca, makhe sicinge ukuba i-frequency resource yindlela yaseMoscow-St. Kubonakala ngathi i-OFDMA icebisa oku: “Masingenzi indlela enye, kodwa ibe mibini, ukuze isetyenziswe kakuhle ngakumbi.” I-MU-MIMO inendlela eyahlukileyo: "Masakhe indlela yesibini, yesithathu ukuze itrafikhi ihambe ngeendlela ezizimeleyo." Ngokwethiyori, enye ayiphikisani nenye, kodwa enyanisweni, indibaniselwano yeendlela ezimbini ifuna isiseko esithile se-algorithmic. Ndiyabulela kwinto yokuba iHuawei ikwazile ukwenza esi siseko, ukuphuma kweendawo zethu zokufikelela kuye kwanda malunga ne-40% xa kuthelekiswa noko abakhuphisana nabo banakho ukunika.

Ngokuphathelele ukhuseleko, iindawo ezintsha zokufikelela, njengeemodeli zangaphambili, zixhasa i-DTLS. Oku kuthetha ukuba, njengangaphambili, i-CAPWAP yolawulo lwetrafikhi inokuguqulelwa ngokuntsonkothileyo.

Ngokukhuselwa kwiimpembelelo ezikhohlakeleyo zangaphandle, yonke into iyafana nakwisizukulwana sangaphambili sabalawuli. Naluphi na uhlobo lohlaselo, nokuba ngamandla akhohlakeleyo, uhlaselo lwe-IV olubuthathaka (ii-vectors zokuqalisa ezibuthathaka) okanye enye into, lufunyenwe ngexesha lokwenyani. Ukusabela kwi-DDoS nako kuqwalaselwe: inkqubo inokudala uluhlu lwabamnyama oluguqukayo, yazisa umlawuli malunga nokuba kwenzekani xa uzama ukuhlaselwa kwenethiwekhi esasazwayo, njl.

Zeziphi izisombululo ezihamba neemodeli ze-AirEngine

Iqonga lethu leCampusInsight Wi-Fi 6 licombulula iingxaki ezininzi. Okokuqala, isetyenziswa kulawulo lukanomathotholo kunye nomlawuli: ICampusInsight ikuvumela ukuba wenze ulungelelwaniso kwaye ngexesha lokwenyani usasaze amajelo, uhlengahlengise amandla esiginali kunye nobubanzi besitishi esithile, kwaye ulawule okwenzekayo ngeWi-Fi. inethiwekhi. Ngayo yonke loo nto, iCampusInsight iyasebenza nakukhuseleko olungenazingcingo (ngokukodwa, kuthintelo lokungena kunye nokufumanisa ukungena), kwaye kungekhona ngokumalunga nendawo ethile yokufikelela okanye i-SSID enye, kodwa kwisikali sayo yonke iziseko ezingenazintambo.

I-WLAN Planner nayo ifanelwe ingqalelo - isixhobo somfanekiso werediyo, kwaye inokuzimela ngokuzimeleyo imiqobo ethile, efana neendonga. Kwisiphumo, inkqubo ivelisa ingxelo emfutshane, ethi, phakathi kwezinye izinto, ibonisa ukuba zingaphi iindawo zokufikelela ezifunekayo ukugubungela igumbi. Ngokusekelwe kwigalelo elinjalo, kulula kakhulu ukwenza izigqibo ezinolwazi ngakumbi malunga neenkcukacha zezixhobo, uhlahlo lwabiwo-mali, njl.

Phakathi kwesoftware, sikwakhankanya i-Cloud Campus App, efumaneka kuye wonke umntu kuzo zombini i-iOS kunye ne-Android kwaye iqulethe iseti epheleleyo yezixhobo zokubeka iliso kwinethiwekhi engenazingcingo. Ezinye zazo zenzelwe ukuvavanya umgangatho we-Wi-Fi (umzekelo, uvavanyo lokuzulazula). Phakathi kwezinye izinto, unokuvavanya inqanaba lomqondiso, ufumane imithombo yokuphazamiseka, khangela i-throughput kwindawo ethile, kwaye ukuba kukho iingxaki, chonga izizathu zabo.
