Kodi mukufuna kudziwa ngati chibwenzi chanu amakonda kusewera masewera apakompyuta?Ndiroleni ndikuuzeni nsonga, mutha kuyang'ana kompyuta yake ndi kugwirizana kwa chingwe kapena ayi.Chifukwa anyamata ali ndi zofunika kwambiri pa liwiro la maukonde ndi kuchedwa pamene akusewera masewera, ndipo ambiri panopa kunyumba WiFi sangathe kuchita izi ngakhale burodibandi maukonde liwiro mofulumira mokwanira, kotero anyamata amene nthawi zambiri masewera amakonda kusankha mawaya kupeza burodibandi kuti. onetsetsani malo ochezera a pa intaneti okhazikika komanso othamanga.
Izi zikuwonetsanso mavuto a kugwirizana kwa WiFi: kuchedwa kwakukulu ndi kusakhazikika, zomwe zikuwonekera kwambiri kwa ogwiritsa ntchito angapo nthawi imodzi, koma izi zidzasintha kwambiri ndi kufika kwa WiFi 6. Ichi ndi chifukwa WiFi 5, yomwe imagwiritsidwa ntchito ndi anthu ambiri, imagwiritsa ntchito ukadaulo wa OFDM, pomwe WiFi 6 imagwiritsa ntchito ukadaulo wa OFDMA.Kusiyana pakati pa njira ziwirizi kutha kufotokozedwa momveka bwino:
Pamsewu womwe INGATHE kukhala ndi galimoto imodzi yokha, OFDMA imatha kutumiza ma terminals angapo nthawi imodzi, kuchotsa mizere ndi kusokonekera, KUKONZEKERA KUGWIRITSA NTCHITO NDIPONSO kuchepetsa kuchedwa.OFDMA imagawa tchanelo chopanda zingwe kukhala ma subchannel angapo pama frequency domain, kuti ogwiritsa ntchito angapo nthawi imodzi azitha kufalitsa deta mofananira nthawi iliyonse, zomwe zimapangitsa kuti magwiridwe antchito komanso kuchepetsa kuchedwa kwa mizere.
WIFI 6 yakhala ikugunda kuyambira pomwe idakhazikitsidwa, popeza anthu amafuna ma netiweki anyumba opanda zingwe.Ma terminal opitilira 2 biliyoni a Wi-Fi 6 adatumizidwa kumapeto kwa 2021, zomwe zimapitilira 50% yazotumiza zonse za Wi-Fi, ndipo chiwerengerochi chidzafika pa 5.2 biliyoni pofika 2025, malinga ndi katswiri wofufuza IDC.
Ngakhale Wi-Fi 6 yayang'ana kwambiri pazomwe ogwiritsa ntchito ali nazo pazambiri zochulukirachulukira, mapulogalamu atsopano atuluka m'zaka zaposachedwa zomwe zimafuna kutulutsa kwapamwamba komanso latency, monga makanema apamwamba kwambiri monga makanema a 4K ndi 8K, kugwira ntchito kutali, kanema wapaintaneti. misonkhano, ndi masewera a VR/AR.Zimphona zamakono zimawonanso mavutowa, ndipo Wi-Fi 7, yomwe imapereka kuthamanga kwambiri, mphamvu zambiri komanso kutsika kochepa, ikukwera.Tiyeni titenge chitsanzo cha Qualcomm's Wi-Fi 7 ndikulankhula zomwe Wi-Fi 7 yasintha.
Wi-fi 7: Zonse za Low Latency
1. Bandwidth Yapamwamba
Apanso, tengani misewu.Wi-fi 6 imathandizira makamaka magulu a 2.4ghz ndi 5ghz, koma msewu wa 2.4ghz wagawidwa ndi Wi-Fi yoyambirira komanso matekinoloje ena opanda zingwe monga Bluetooth, motero imakhala yodzaza kwambiri.Misewu ya 5GHz ndi yotakata komanso yocheperapo kusiyana ndi 2.4ghz, yomwe imatanthawuza kuthamanga mofulumira komanso mphamvu zambiri.Wi-fi 7 imathandizira ngakhale gulu la 6GHz pamwamba pa magulu awiriwa, kukulitsa m'lifupi mwa njira imodzi kuchokera pa Wi-Fi 6's 160MHz mpaka 320MHz (yomwe imatha kunyamula zinthu zambiri panthawi imodzi).Panthawiyo, Wi-Fi 7 idzakhala ndi chiwongola dzanja choposa 40Gbps, kuwirikiza kanayi kuposa Wi-Fi 6E.
2. Multi-link Access
Pamaso pa Wi-Fi 7, ogwiritsa ntchito amatha kugwiritsa ntchito njira imodzi yokha yomwe ikugwirizana ndi zosowa zawo, koma yankho la Qualcomm la Wi-Fi 7 limakankhira malire a Wi-Fi mopitilira: mtsogolomo, magulu onse atatu azitha kugwira ntchito nthawi imodzi, kuchepetsa kuchulukana.Kuphatikiza apo, pogwiritsa ntchito maulalo ambiri, ogwiritsa ntchito amatha kulumikizana kudzera munjira zingapo, kugwiritsa ntchito mwayi uwu kuti apewe kusokonekera.Mwachitsanzo, ngati pali magalimoto pa tchanelo chimodzi, chipangizocho chitha kugwiritsa ntchito tchanelo china, zomwe zimapangitsa kuti mayendedwe achepe.Pakadali pano, kutengera kupezeka kwa zigawo zosiyanasiyana, maulalo angapo amatha kugwiritsa ntchito njira ziwiri mugulu la 5GHz kapena kuphatikiza njira ziwiri mumagulu a 5GHz ndi 6GHz.
3. Aggregate Channel
Monga tafotokozera pamwambapa, bandwidth ya Wi-Fi 7 yawonjezeka kufika 320MHz (m'lifupi mwagalimoto).Kwa gulu la 5GHz, palibe gulu la 320MHz lopitilira, kotero ndi dera la 6GHz lokha lomwe lingathe kuthandizira njira yopitilira iyi.Ndi ntchito yolumikizana ndi ma bandwidth apamwamba nthawi imodzi, magulu awiri afupipafupi amatha kusonkhanitsidwa nthawi imodzi kuti asonkhanitse kutulutsa kwa mayendedwe awiriwa, ndiye kuti, ma siginecha awiri a 160MHz amatha kuphatikizidwa kuti apange njira yothandiza ya 320MHz (m'lifupi mwake).Mwanjira imeneyi, dziko ngati lathu, lomwe silinagawire mawonekedwe a 6GHz, lithanso kupereka njira yokwanira yokwaniritsira kutulutsa kwakukulu m'mikhalidwe yodzaza.
4.4K QAM
Kusintha kwapamwamba kwambiri kwa Wi-Fi 6 ndi 1024-QAM, pomwe Wi-Fi 7 imatha kufikira 4K QAM.Mwanjira iyi, chiwongoladzanja chikhoza kuwonjezeka kuti chiwonjezeke kupititsa patsogolo ndi mphamvu ya deta, ndipo liwiro lomaliza likhoza kufika ku 30Gbps, yomwe ili katatu liwiro la 9.6Gbps WiFi 6.
Mwachidule, Wi-Fi 7 idapangidwa kuti izipereka liwiro lalitali kwambiri, kuchuluka kwambiri, komanso kutumiza kwa data pang'onopang'ono powonjezera kuchuluka kwa misewu yomwe ilipo, m'lifupi mwagalimoto iliyonse yonyamula deta, komanso m'lifupi mwanjira yoyenda.
Wi-fi 7 Imawulula Njira Yopangira Ma IoT othamanga kwambiri
M'malingaliro a wolemba, pachimake chaukadaulo watsopano wa Wi-Fi 7 sikungowonjezera kuchuluka kwa chipangizo chimodzi, komanso kusamala kwambiri kufalikira kwapanthawi yomweyo komwe kumagwiritsidwa ntchito ndi ogwiritsa ntchito ambiri (ambiri. -lane access) zochitika, zomwe mosakayikira zikugwirizana ndi nthawi yomwe ikubwera ya intaneti ya Zinthu.Kenako, wolembayo alankhula za zochitika zopindulitsa kwambiri za iot:
1. Internet Internet of Zinthu
Chimodzi mwazovuta zazikulu zaukadaulo wa iot pakupanga ndi bandwidth.Deta yowonjezera yomwe ingalankhulidwe nthawi imodzi, Iot idzakhala yofulumira komanso yothandiza kwambiri.Pankhani yowunikira kutsimikizika kwaukadaulo mu Industrial Internet of Things, liwiro la netiweki ndilofunika kwambiri kuti ntchito zanthawi yeniyeni zitheke.Mothandizidwa ndi maukonde othamanga kwambiri a Iiot, zidziwitso zenizeni zenizeni zimatha kutumizidwa munthawi yake kuti zitha kuyankha mwachangu kumavuto monga kulephera kwa makina mosayembekezereka ndi zosokoneza zina, kupititsa patsogolo kwambiri zokolola ndi mphamvu zamabizinesi opanga ndikuchepetsa ndalama zosafunikira.
2. Computing M'mphepete
Ndi kufunikira kwa anthu kuti ayankhe mwachangu pamakina anzeru komanso chitetezo cha data pa intaneti ya Zinthu chikukulirakulira, cloud computing idzakhala yotsalira m'tsogolomu.Makompyuta a m'mphepete amangotanthauza makompyuta kumbali ya wogwiritsa ntchito, zomwe zimafuna osati mphamvu zogwiritsira ntchito makompyuta pambali ya wogwiritsa ntchito, komanso kuthamanga kokwanira kotumizira deta kumbali ya wogwiritsa ntchito.
3. Immersive AR/VR
Immersive VR imayenera kuyankha mwachangu molingana ndi zomwe osewera akuchita nthawi yeniyeni, zomwe zimafunikira kuchedwa kwambiri kwamaneti.Ngati nthawi zonse mumapereka osewera kuyankha pang'onopang'ono, ndiye kuti kumizidwa ndi chinyengo.Wi-fi 7 ikuyembekezeka kuthetsa vutoli ndikufulumizitsa kukhazikitsidwa kwa AR/VR yozama.
4. Chitetezo chanzeru
Ndi chitukuko cha chitetezo chanzeru, chithunzi chofalitsidwa ndi makamera anzeru chikuwonjezeka kwambiri, zomwe zikutanthauza kuti deta yamphamvu yomwe imafalitsidwa ikukula ndikukula, ndipo zofunikira za bandiwifi ndi liwiro la intaneti zikukweranso.Pa LAN, WIFI 7 mwina ndiye njira yabwino kwambiri.
Kumapeto
Wi-fi 7 ndiyabwino, koma pakadali pano, mayiko akuwonetsa malingaliro osiyanasiyana ngati angalole WiFi kulowa mu 6GHz (5925-7125mhz) gulu ngati gulu lopanda chilolezo.Dzikoli silinaperekebe mfundo zomveka bwino pa 6GHz, koma ngakhale gulu la 5GHz likupezeka, Wi-Fi 7 ikhoza kuperekabe kufalikira kwa 4.3Gbps, pamene Wi-Fi 6 imangothandiza kuthamanga kwapamwamba kwa 3Gbps. pamene gulu la 6GHz likupezeka.Chifukwa chake, zikuyembekezeka kuti Wi-Fi 7 itenga gawo lofunikira kwambiri pama Lans othamanga kwambiri m'tsogolomu, kuthandiza zida zanzeru zambiri kuti zisagwidwe ndi chingwe.
