Kodi mukufuna kudziwa ngati chibwenzi chanu chimakonda kusewera masewera apakompyuta? Ndiloleni ndikugawireni upangiri, mutha kuwona ngati kompyuta yake ili ndi intaneti yolumikizidwa kapena ayi. Chifukwa anyamata amafunikira kwambiri liwiro la netiweki komanso kuchedwa akamasewera masewera, ndipo WiFi yambiri yakunyumba singathe kuchita izi ngakhale liwiro la netiweki ya broadband ndi lokwanira, kotero anyamata omwe nthawi zambiri amasewera masewera amakonda kusankha mwayi wolumikizana ndi intaneti kuti atsimikizire kuti netiwekiyo ndi yokhazikika komanso yachangu.
Izi zikuwonetsanso mavuto a kulumikizana kwa WiFi: kuchedwa kwambiri komanso kusakhazikika, zomwe zimaonekera kwambiri kwa ogwiritsa ntchito ambiri nthawi imodzi, koma vutoli lidzasintha kwambiri WiFi 6 ikafika. Izi zili choncho 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 kungawonetsedwe mozama:
Pa msewu womwe ungalole galimoto imodzi yokha, OFDMA imatha kutumiza ma terminals angapo nthawi imodzi, kuchotsa mizere ndi kutsekeka kwa magalimoto, KUKONZA KUGWIRITSA NTCHITO BWINO NDI KUCHEPETSA kuchedwa. OFDMA imagawa njira yopanda zingwe m'ma subchannels angapo mu frequency domain, kuti ogwiritsa ntchito angapo athe kutumiza deta nthawi imodzi nthawi imodzi, zomwe zimapangitsa kuti magwiridwe antchito aziyenda bwino komanso kuchepetsa kuchedwa kwa mizere.
WIFI 6 yakhala ikugwiritsidwa ntchito kwambiri kuyambira pomwe idakhazikitsidwa, chifukwa anthu akufuna ma netiweki ambiri opanda zingwe kunyumba. Ma terminal a Wi-Fi 6 opitilira 2 biliyoni adatumizidwa kumapeto kwa chaka cha 2021, zomwe zimapangitsa kuti pakhale zoposa 50% ya kutumiza kwa ma terminal a Wi-Fi, ndipo chiwerengerochi chidzakula kufika pa 5.2 biliyoni pofika chaka cha 2025, malinga ndi kampani yofufuza za IDC.
Ngakhale kuti Wi-Fi 6 yakhala ikuyang'ana kwambiri pa zomwe ogwiritsa ntchito akumana nazo pazochitika za anthu ambiri, mapulogalamu atsopano atuluka m'zaka zaposachedwa omwe amafuna kufalikira kwakukulu komanso kuchedwa, monga makanema apamwamba kwambiri monga makanema a 4K ndi 8K, kugwira ntchito patali, misonkhano yamavidiyo pa intaneti, ndi masewera a VR/AR. Makampani akuluakulu aukadaulo amawonanso mavutowa, ndipo Wi-Fi 7, yomwe imapereka liwiro lalikulu, mphamvu zambiri komanso kuchedwa kochepa, ikuyenda bwino kwambiri. Tiyeni titenge Wi-Fi 7 ya Qualcomm ngati chitsanzo ndikukambirana zomwe Wi-Fi 7 yasintha.
Wi-fi 7: Zonse chifukwa cha kuchepa kwa nthawi yogwira ntchito
1. Bandwidth Yapamwamba
Apanso, tengani misewu. Wi-fi 6 imathandizira makamaka ma band a 2.4ghz ndi 5ghz, koma msewu wa 2.4ghz wakhala ukugawidwa ndi Wi-Fi yoyambirira ndi ukadaulo wina wopanda zingwe monga Bluetooth, kotero umakhala wodzaza kwambiri. Misewu ya 5GHz ndi yayikulu komanso yodzaza pang'ono kuposa 2.4ghz, zomwe zikutanthauza kuti liwiro ndi mphamvu zambiri. Wi-fi 7 imathandiziranso band ya 6GHz pamwamba pa ma band awiriwa, kukulitsa m'lifupi mwa njira imodzi kuchokera pa Wi-Fi 6's 160MHz mpaka 320MHz (yomwe imatha kunyamula zinthu zambiri nthawi imodzi). Panthawiyo, Wi-Fi 7 idzakhala ndi liwiro lalikulu la kutumiza ma band opitilira 40Gbps, kuwirikiza kanayi kuposa Wi-Fi 6E.
2. Kupeza maulalo ambiri
Asanayambe Wi-Fi 7, ogwiritsa ntchito ankatha kugwiritsa ntchito msewu umodzi wokha womwe umagwirizana ndi zosowa zawo, koma njira ya Qualcomm's Wi-Fi 7 imapititsa patsogolo malire a Wi-Fi: mtsogolomu, magulu onse atatu azitha kugwira ntchito nthawi imodzi, kuchepetsa kuchulukana kwa anthu. Kuphatikiza apo, kutengera ntchito ya multi-link, ogwiritsa ntchito amatha kulumikizana kudzera munjira zingapo, kugwiritsa ntchito mwayi uwu kuti apewe kuchulukana kwa anthu. Mwachitsanzo, ngati pali magalimoto pa imodzi mwa njirazi, chipangizocho chingagwiritse ntchito njira inayo, zomwe zimapangitsa kuti pakhale kuchedwa kochepa. Pakadali pano, kutengera kupezeka kwa madera osiyanasiyana, multi-link ingagwiritse ntchito njira ziwiri mu gulu la 5GHz kapena kuphatikiza njira ziwiri mu magulu a 5GHz ndi 6GHz.
3. Njira Yophatikiza
Monga tafotokozera pamwambapa, bandwidth ya Wi-Fi 7 yawonjezeka kufika pa 320MHz (m'lifupi mwa galimoto). Pa gulu la 5GHz, palibe gulu la 320MHz lopitirira, kotero dera la 6GHz lokha ndi lomwe lingathe kuthandizira njira yopitilira iyi. Ndi ntchito ya multi-link ya high-bandwidth nthawi imodzi, magulu awiri afupipafupi amatha kusonkhana nthawi imodzi kuti asonkhanitse mphamvu ya njira ziwirizi, kutanthauza kuti, zizindikiro ziwiri za 160MHz zitha kuphatikizidwa kuti zipange njira yogwira ntchito ya 320MHz (m'lifupi wokulirapo). Mwanjira imeneyi, dziko ngati lathu, lomwe silinaperekebe 6GHz spectrum, lingaperekenso njira yogwira ntchito yokwanira kuti ikwaniritse mphamvu yogwira ntchito kwambiri m'malo odzaza.
4. 4K QAM
Kusinthasintha kwapamwamba kwambiri kwa Wi-Fi 6 ndi 1024-QAM, pomwe Wi-Fi 7 imatha kufika 4K QAM. Mwanjira imeneyi, chiwongola dzanja chachikulu chikhoza kuwonjezeredwa kuti chiwonjezere kuchuluka kwa deta ndi mphamvu ya data, ndipo liwiro lomaliza likhoza kufika 30Gbps, lomwe ndi liwiro lowirikiza katatu kuposa liwiro la 9.6Gbps la WiFi 6 lomwe lili pano.
Mwachidule, Wi-Fi 7 idapangidwa kuti ipereke liwiro lapamwamba kwambiri, mphamvu yayikulu, komanso kutumiza deta mochedwa kwambiri powonjezera kuchuluka kwa misewu yomwe ilipo, m'lifupi mwa galimoto iliyonse yonyamula deta, ndi m'lifupi mwa msewu woyendera.
Wi-fi 7 Imatsegula Njira Yogwiritsira Ntchito IoT Yothamanga Kwambiri Yolumikizidwa Kwambiri
Malinga ndi maganizo a wolemba, mfundo yaikulu ya ukadaulo watsopano wa Wi-Fi 7 sikuti ndi kungowonjezera kuchuluka kwa chipangizo chimodzi, komanso kuyang'anira kwambiri kufalikira kwapamwamba kwa nthawi imodzi pogwiritsa ntchito zochitika za ogwiritsa ntchito ambiri (njira zambiri), zomwe mosakayikira zikugwirizana ndi nthawi yomwe ikubwera ya Internet of Things. Kenako, wolembayo adzalankhula za zochitika zabwino kwambiri za iot:
1. Intaneti ya Zinthu Zamakampani
Chimodzi mwa zinthu zovuta kwambiri pa ukadaulo wa iot popanga zinthu ndi bandwidth. Deta yochuluka yomwe ingatumizidwe nthawi imodzi, Iot idzakhala yachangu komanso yothandiza kwambiri. Pankhani yowunikira kutsimikizika kwa khalidwe mu Industrial Internet of Things, liwiro la netiweki ndilofunika kwambiri kuti mapulogalamu a nthawi yeniyeni apambane. Mothandizidwa ndi netiweki ya Ioot yothamanga kwambiri, machenjezo a nthawi yeniyeni amatha kutumizidwa nthawi yomweyo kuti ayankhe mwachangu mavuto monga kulephera kwa makina kosayembekezereka ndi kusokonezeka kwina, zomwe zimapangitsa kuti makampani opanga zinthu azigwira bwino ntchito komanso kuchepetsa ndalama zosafunikira.
2. Kuwerengera kwa Mphepete
Popeza anthu akufuna makina anzeru kuti agwire ntchito mwachangu komanso chitetezo cha deta cha intaneti ya zinthu chikukwera kwambiri, kugwiritsa ntchito makompyuta pa intaneti kudzachepetsedwa mtsogolo. Edge computing imangotanthauza kugwiritsa ntchito makompyuta kumbali ya ogwiritsa ntchito, zomwe sizimangofuna mphamvu zambiri zogwiritsira ntchito pa intaneti, komanso liwiro lokwanira lotumizira deta kumbali ya ogwiritsa ntchito.
3. AR/VR yozama kwambiri
VR yozama imafunika kuyankha mwachangu molingana ndi zomwe osewera amachita nthawi yeniyeni, zomwe zimafuna kuchedwa kwambiri kwa netiweki. Ngati nthawi zonse mumapereka osewera yankho pang'onopang'ono, ndiye kuti kumiza ndi chinyengo. Wi-fi 7 ikuyembekezeka kuthetsa vutoli ndikufulumizitsa kugwiritsa ntchito AR/VR yozama.
4. Chitetezo chanzeru
Ndi chitukuko cha chitetezo chanzeru, chithunzi chotumizidwa ndi makamera anzeru chikukhala chodziwika bwino kwambiri, zomwe zikutanthauza kuti deta yosinthika yotumizidwa ikukulirakulira, ndipo zofunikira pa bandwidth ndi liwiro la netiweki zikukulirakulira. Pa LAN, WIFI 7 mwina ndiye njira yabwino kwambiri.
Kumapeto
Wi-fi 7 ndi yabwino, koma pakadali pano, mayiko akuwonetsa malingaliro osiyanasiyana pankhani yoti alole WiFi kulowa mu gulu la 6GHz (5925-7125mhz) ngati gulu lopanda chilolezo. Dzikoli silinaperekebe mfundo zomveka bwino pa 6GHz, koma ngakhale gulu la 5GHz lokha likupezeka, Wi-Fi 7 ikhoza kuperekabe chiwongola dzanja chachikulu cha 4.3Gbps, pomwe Wi-Fi 6 imathandizira liwiro lotsitsa la 3Gbps pamene gulu la 6GHz likupezeka. Chifukwa chake, akuyembekezeka kuti Wi-Fi 7 idzakhala ndi gawo lofunika kwambiri mu ma Lans othamanga kwambiri mtsogolo, kuthandiza zida zambiri zanzeru kuti zisagwidwe ndi chingwe.
