Chechipiri chikamu chakakamurwa nehuwandu hwenguva yechiratidzo uye nguva yenguva yevarindi zvinoenderana nechiyero chakashandiswa. Sezvo muWi-Fi 6 nguva yechiratidzo yakapetwa kakapetwa kusvika ku12,8 μs, uye nguva yevarindi i 0,8 μs, mhedzisiro i1/13,6 μs.

Tevere: sechiyeuchidzo, nekuda kwekuvandudzwa kwe1024-QAM modulation, anosvika gumi mabhiti ikozvino anogona kukodha pachiratidzo. Pakazara, isu tine bitrate ye10/5 (FEC) - yechina yekuwedzera. Uye yechishanu ndiyo nhamba ye subcarriers (matoni).

Pakupedzisira, tichiwedzera kushanda kwepamusoro kwe2,4 uye 5 GHz, tinowana kukosha kunoshamisa kwe10,75 Gbps.

DBS radio frequency resource manejimendi yakaonekwawo munzvimbo dzedu dzekuwana uye vatongi. Kana kare waifanira kusarudza hupamhi hwechiteshi kune imwe SSID kamwe (20, 40 kana 80 MHz), zvino zvinogoneka kugadzirisa mutongi kuti aite izvi zvine simba.

Imwezve kuvandudzwa mukugova zviwanikwa zveredhiyo yakaunzwa nehunyanzvi hweSmartRadio. Kare, kana paiva nenzvimbo dzakawanda dzekuwana munzvimbo imwe chete, zvaikwanisika kutsanangura nealgorithm yekugoverazve vatengi, iyo AP yekubatanidza imwe itsva, nezvimwewo. Asi zvigadziriso izvi zvakashandiswa kamwe chete, panguva yekubatana kwayo uye kushamwaridzana neWi-Fi network. Panyaya yeAirEngine, maalgorithms ekuyeresa mutoro anogona kuiswa munguva chaiyo vatengi vari kushanda uye, semuenzaniso, kufamba pakati penzvimbo dzekuwana.

Yakakosha nuance ine chekuita neantenna zvinhu: muAirEngine modhi ivo panguva imwe chete vanoisa zvese zvakamira uye zvakachinjika polarization. Imwe neimwe inotsigira mana antenna, uye pane zvinhu zvina zvakadaro. Nokudaro nhamba yose - 16 antennas.

Iyo antenna element pachayo ndeyekuita. Saizvozvo, kuti utarise simba rakawanda munzira yemutengi, zvinodikanwa kugadzira danda rakatetepa uchishandisa compact antennas. Huawei akabudirira. Mhedzisiro ndeyekuburitswa kweredhiyo paavhareji 20% yakakura kupfuura iyo yemakwikwi emhinduro.

NeWi-Fi 6, ultra-high throughput uye high modulation levels (MCS 10 uye MCS 11 zvirongwa) zvinogoneka chete kana chiratidzo-ku-ruzha reshiyo, kana Signal-to-Noise Ratio, inodarika 35 dB. Yese decibel inokosha. Uye iyo antenna yakangwara inobvumidza iwe kuti uwedzere nhanho yechiratidzo chakagamuchirwa.

Mumiyedzo chaiyo, 1024-QAM modulation neMCS 10 chirongwa chichashanda chinhambwe chisingapfuure 3 m kubva panzvimbo yekuwana, chero ipi iripo pamusika. Zvakanaka, kana uchishandisa "smart" antenna, kureba kunogona kuwedzerwa kusvika 6-7 m.

Imwe tekinoroji iyo Huawei akabatanidza munzvimbo nyowani dzekuwana inonzi Dynamic Turbo. Hunhu hwayo huri muchokwadi chekuti AP inokwanisa kuziva uye kurongedza zvikumbiro panhunzi nekirasi (semuenzaniso, inotumira chaiyo-nguva vhidhiyo, izwi traffic kana chimwewo chinhu), kusiyanisa vatengi zvichienderana nekukosha kwavo uye kugovera zviwanikwa zvekushandisa mu. nzira yakadaro yekuona kuti zvikumbiro zvepamusoro zvakakosha kune vashandisi zvinomhanya nekukurumidza sezvinobvira. Muchokwadi, padanho rehardware, nzvimbo yekuwana inoita DPI - yakadzika traffic yekuongorora.

Sezvambotaurwa, Huawei parizvino ndiye ega mutengesi anopa panguva imwe chete kushanda kweMU-MIMO neOFDMA mumhinduro dzayo. Ngatitorei zvishoma zvakadzama nezve musiyano pakati pavo.

Matekinoroji ese ari maviri akagadzirirwa kupa akawanda-mushandisi kuwana. Kana paine vashandisi vazhinji munetiweki, OFDMA inobvumira frequency sosi kugovaniswa kuitira kuti vatengi vazhinji vagamuchire uye vagamuchire ruzivo panguva imwe chete. Nekudaro, MU-MIMO inozopedzisira yavavarira chinhu chimwe chete: kana vatengi vakati wandei vari munzvimbo dzakasiyana mukamuri, mumwe nemumwe wavo anogona kutumirwa yakasarudzika kuyerera kwenzvimbo. Nokuda kwekujekesa, ngatifungei kuti frequency resource ndiyo nzira yeMoscow-St. OFDMA inoita seiri kupa zano rokuti: “Ngatiite mugwagwa usava mugwagwa mumwe chete, asi miviri, kuti ugoshandiswa zvinobudirira zvikuru.” MU-MIMO ine imwe nzira: "Ngativake yechipiri, yechitatu mugwagwa kuitira kuti traffic ifambe nenzira dzakazvimirira." Nedzidziso, imwe haipokane neimwe, asi muchokwadi, musanganiswa wenzira mbiri inoda imwe algorithmic hwaro. Nekuda kwekuti Huawei akakwanisa kugadzira hwaro uhwu, kubuda kwenzvimbo dzedu dzekuwana kwakawedzera neinosvika 40% zvichienzaniswa nezvinopihwa nevakwikwidzi.

Nezve kuchengetedzeka, nzvimbo nyowani dzekuwana, senge mamodheru apfuura, inotsigira DTLS. Izvi zvinoreva, sepakutanga, CAPWAP inodzora traffic inogona kuvharirwa.

Nedziviriro kubva kune zvekunze zvakaipa pesvedzero, zvese zvakafanana nezviri muchizvarwa chekare chevatongi. Chero rudzi rwekurwisa, kungave hutsinye simba, Weak IV kurwisa (kusasimba kwekutanga mavheji) kana chimwe chinhu, inoonekwa munguva chaiyo. Maitiro kuDDoS anogadzirika zvakare: iyo sisitimu inogona kugadzira mablacklists, zivisa maneja nezve zviri kuitika kana uchiedza kuparadzirwa network kurwisa, nezvimwe.

Ndedzipi mhinduro dzinoperekedza AirEngine modhi

Yedu CampusInsight Wi-Fi 6 analytics chikuva inogadzirisa akati wandei matambudziko. Chekutanga pane zvese, inoshandiswa muredhiyo manejimendi pamwe chete nemutongi: CampusInsight inokutendera kuti uite calibration uye munguva chaiyo yakanakisa kugovera chiteshi, gadzirisa simba rechiratidzo uye bandwidth yeimwe chiteshi, uye kutonga zviri kuitika neWi-Fi. network. Nezvese izvo, CampusInsight inoshandawo mukuchengetedzeka kusina waya (kunyanya, yekudzivirira kupindira uye kuona kupindira), uye kwete zvine chekuita nenzvimbo yekupinda kana imwe SSID, asi pachiyero cheiyo yese isina waya.

WLAN Planner inofanirwawo kutariswa - chishandiso cheredhiyo modhi, uye inogona kuzvimiririra kuona zvimwe zvipingamupinyi, semadziro.
