Unoda kuziva here kana mukomana wako achida kutamba mitambo yekombuta? Regai ndikupei zano, munogona kutarisa kuti komputa yake ine network cable connection here kana kuti kwete. Nekuti vakomana vane zvinodiwa zvakanyanya pakumhanya kwenetwork uye kunonoka pakutamba mitambo, uye WiFi yakawanda yepamba haigone kuita izvi kunyangwe kumhanya kwenetwork yebroadband kuchikurumidza zvakakwana, saka vakomana vanowanzo tamba mitambo vanowanzo sarudza wired access kune broadband kuti vave nechokwadi chekuti network inogara yakagadzikana uye inokurumidza.
Izvi zvinoratidzawo matambudziko ekubatana kweWiFi: kunonoka kwakanyanya uye kusagadzikana, izvo zviri pachena kana paine vashandisi vakawanda panguva imwe chete, asi mamiriro ezvinhu aya achavandudzwa zvikuru nekusvika kweWiFi 6. Izvi zvinodaro nekuti WiFi 5, iyo inoshandiswa nevanhu vazhinji, inoshandisa tekinoroji yeOFDM, nepo WiFi 6 ichishandisa tekinoroji yeOFDMA. Musiyano uripo pakati pematekiniki maviri aya unogona kuratidzwa nemifananidzo:
Mumugwagwa unogona kungotakura mota imwe chete, OFDMA inogona kutumira materminal akawanda panguva imwe chete, ichibvisa mitsetse nekuzara kwemotokari, ichivandudza kushanda zvakanaka uye ichideredza kunonoka. OFDMA inokamura chiteshi chewireless kuita mitsetse midiki yakawanda munzvimbo yema frequency, kuitira kuti vashandisi vakawanda vagone kutumira data panguva imwe chete panguva imwe chete, izvo zvinovandudza kushanda zvakanaka uye zvinoderedza kunonoka kwekufamba mumutsara.
WIFI 6 yave nekubudirira kukuru kubva payakatanga kushandiswa, sezvo vanhu vachida ma network epamba asingashandise waya akawanda. Ma terminal eWi-Fi 6 anopfuura mabhiriyoni maviri akatumirwa pakupera kwa2021, zvichireva kuti anopfuura 50% yekutumira kwese kweWi-Fi terminal, uye nhamba iyoyo ichakura kusvika mabhiriyoni mashanu nehafu panosvika gore ra2025, sekureva kwekambani yekuongorora IDC.
Kunyangwe Wi-Fi 6 yakatarisana neruzivo rwevashandisi mune zviitiko zvehuwandu hwevanhu vakawanda, maapplication matsva akabuda mumakore achangopfuura anoda throughput yakakwira uye latency, senge mavhidhiyo e-ultra-high-definition akadai se4K ne8K mavhidhiyo, kushanda uri kure, online video conferencing, uye VR/AR games. Makambani makuru etekinoroji anoonawo matambudziko aya, uye Wi-Fi 7, iyo inopa kumhanya kwakanyanya, kugona kwakanyanya uye latency yakaderera, iri kufamba zvakanaka. Ngatitorei Wi-Fi 7 yeQualcomm semuenzaniso totaura nezvezvakavandudzwa neWi-Fi 7.
Wi-fi 7: Zvese zveLatency Yakaderera
1. Bandwidth Yakakwirira
Zvakare, tora migwagwa. Wi-fi 6 inonyanya kutsigira mabhendi e2.4ghz ne5ghz, asi mugwagwa we2.4ghz waishandiswawo neWi-Fi yekare nedzimwe tekinoroji dzisina waya dzakadai seBluetooth, saka unova wakazara zvikuru. Migwagwa ye5GHz yakafara uye haina vanhu vakawanda kupfuura ye2.4ghz, izvo zvinoshandura kumhanya nekukurumidza uye kugona kwakawanda. Wi-fi 7 inotsigirawo bhendi re6GHz pamusoro pemabhendi maviri aya, ichiwedzera upamhi hwechiteshi chimwe chete kubva paWi-Fi 6's 160MHz kusvika ku320MHz (inogona kutakura zvinhu zvakawanda panguva imwe chete). Panguva iyoyo, Wi-Fi 7 ichave nenhamba yepamusoro yekutumira inodarika 40Gbps, yakapetwa kana kupfuura Wi-Fi 6E.
2. Kupinda kwezvinobatanidza zvakawanda
Wi-Fi 7 isati yasvika, vashandisi vaigona kushandisa mugwagwa mumwe chete wainyatsoenderana nezvavanoda, asi mhinduro yeQualcomm's Wi-Fi 7 inosundira miganhu yeWi-Fi zvakanyanya: mune ramangwana, mabhendi ese matatu achakwanisa kushanda panguva imwe chete, zvichideredza kuzara kwedata. Pamusoro pezvo, zvichibva pabasa re multi-link, vashandisi vanogona kubatana kuburikidza nemachaneli akawanda, vachishandisa izvi kudzivirira kuzara kwedata. Semuenzaniso, kana paine traffic pane imwe yemachaneli, mudziyo unogona kushandisa imwe channel, zvichikonzera kunonoka kushoma. Panguva imwecheteyo, zvichienderana nekuwanikwa kwenzvimbo dzakasiyana, multi-link inogona kushandisa machaneli maviri mubhendi re5GHz kana musanganiswa wemachaneli maviri mumabhandi e5GHz ne6GHz.
3. Nzira Yekubatanidza
Sezvambotaurwa pamusoro apa, bandwidth yeWi-Fi 7 yakawedzerwa kusvika pa320MHz (upamhi hwemota). Kune bhendi re5GHz, hapana bhendi re320MHz rinoenderera mberi, saka nharaunda ye6GHz chete ndiyo inogona kutsigira iyi continuous mode. Nebasa rehigh-bandwidth panguva imwe chete multi-link, ma frequency band maviri anogona kuunganidzwa panguva imwe chete kuti atore throughput yema channel maviri, kureva kuti, masaini maviri e160MHz anogona kusanganiswa kuti agadzire 320MHz effective channel (extended width). Nenzira iyi, nyika yakaita seyedu, iyo isati yagovera 6GHz spectrum, inogonawo kupa chiteshi chakafara zvakakwana kuti iwane throughput yakakwira zvikuru mumamiriro ezvinhu akawandisa.
4. 4K QAM
Kuchinja kwakanyanya kweWi-Fi 6 i1024-QAM, nepo Wi-Fi 7 ichigona kusvika 4K QAM. Nenzira iyi, mwero wepamusoro unogona kuwedzerwa kuti uwedzere kugona kwekushandisa data, uye kumhanya kwekupedzisira kunogona kusvika 30Gbps, inova kumhanya katatu kupfuura 9.6Gbps yeWiFi 6 iripo.
Muchidimbu, Wi-Fi 7 yakagadzirirwa kupa data rinomhanya zvakanyanya, rine simba rakawanda, uye rinononoka zvishoma nekuwedzera huwandu hwenzira dziripo, upamhi hwemotokari yega yega inotakura data, uye upamhi hwenzira yekufamba.
Wi-fi 7 Inovhura Nzira yeIoT ine Speed-Speed Multi-connected
Mukufunga kwemunyori, chinangwa chikuru kwetekinoroji itsva yeWi-Fi 7 hachisi chekuvandudza mwero wepamusoro wemudziyo mumwe chete, asiwo kutarisisa zvakanyanya kutumirwa kwepamusoro-soro panguva imwe chete uchishandisa zviitiko zvevashandisi vakawanda (multi-lane access), izvo zviri maererano nenguva yeInternet of Things iri kuuya. Tevere, munyori achataura nezvezviitiko zvinobatsira zvikuru zveiot:
1. Indaneti yezvinhu zvemaindasitiri
Chimwe chezvipingamupinyi zvikuru zve tekinoroji ye iot mukugadzira i bandwidth. Kana data rakawanda rinogona kutaurwa panguva imwe chete, Iiot inokurumidza uye inoshanda zvakanyanya. Panyaya yekutarisa kunaka kwebhizinesi muIndustrial Internet of Things, kumhanya kwenetwork kwakakosha pakubudirira kwemaapplications enguva chaiyo. Nerubatsiro rwe network yeIiot inokurumidza, zviziviso zvenguva chaiyo zvinogona kutumirwa nenguva kuti zvipindure nekukurumidza kumatambudziko akadai sekukundikana kwemuchina kusingatarisirwi uye kumwe kukanganisa, zvichivandudza zvikuru kugona kwemakambani ekugadzira uye kuderedza mari isingakoshi.
2. Edge Computing
Nekuda kwevanhu kuti michina yakangwara ipindure nekukurumidza uye kuchengetedzeka kwedata reInternet of Things kuri kuramba kuchiwedzera, cloud computing icharamba ichidzikira mune ramangwana. Edge computing inongoreva computing kudivi remushandisi, iyo inoda kwete simba repamusoro remakombiyuta chete kudivi remushandisi, asiwo kumhanya kwakakwana kwekutumira data kudivi remushandisi.
3. AR/VR inonyudza
VR inonyudza inofanirwa kuita mhinduro nekukurumidza zvichienderana nezviito zvevatambi panguva chaiyo, izvo zvinoda kunonoka kwakanyanya kwenetwork. Kana uchigara uchipa vatambi mhinduro inononoka kamwe chete, saka kunyudza inhema. Wi-fi 7 inotarisirwa kugadzirisa dambudziko iri uye kukurumidzisa kushandiswa kweAR/VR inonyudza.
4. Kuchengetedzwa kwakangwara
Nekuvandudzwa kwekuchengetedzwa kwehunyanzvi, mufananidzo unotumirwa nemakamera akangwara uri kuramba uchichinja-chinja, zvinoreva kuti data rinotumirwa riri kuramba richikura, uye zvinodiwa zvebandwidth nekumhanya kwenetwork zviri kuramba zvichikwirawo. PaLAN, WIFI 7 ingangove ndiyo sarudzo yakanakisa.
Pakuguma
Wi-fi 7 yakanaka, asi pari zvino, nyika dziri kuratidza mafungiro akasiyana pamusoro pekuti dzingabvumira WiFi kupinda mubhendi re6GHz (5925-7125mhz) sebhendi risina rezenisi here. Nyika haisati yapa mutemo wakajeka pa6GHz, asi kunyangwe kana bhendi re5GHz chete riripo, Wi-Fi 7 inogona kupa huwandu hwekutumira hunosvika 4.3Gbps, nepo Wi-Fi 6 ichingotsigira kumhanya kwepamusoro kwe3Gbps kana bhendi re6GHz riripo. Saka, zvinotarisirwa kuti Wi-Fi 7 ichaita basa rakakosha muLans dzinomhanya zvakanyanya mune ramangwana, zvichibatsira michina yakawanda yakangwara kudzivirira kubatwa netambo.
