Unoda kuziva kana mukomana wako achifarira kutamba mitambo yemakomputa?Rega ndikupe zano, unogona kutarisa komputa yake ndeye network tambo yekubatanidza kana kwete.Nekuti vakomana vane zvakakwirira zvinodiwa pakumhanya kwenetiweki uye kunonoka kana uchitamba mitambo, uye mazhinji emazuva ano WiFi kumba haigone kuita izvi kunyangwe iyo Broadband network ichimhanya zvakaringana, saka vakomana vanowanzo tamba mitambo vanowanzo sarudza wired kupinda kune Broadband chengetedza yakagadzikana uye nekukurumidza network nharaunda.
Izvi zvinoratidzawo matambudziko ekubatanidza WiFi: high latency uye kusagadzikana, izvo zvinonyanya kuoneka munyaya yevashandisi vakawanda panguva imwe chete, asi mamiriro ezvinhu aya achavandudzwa zvikuru nekusvika kweWiFi 6. Izvi ndezvokuti WiFi 5, iyo inoshandiswa nevanhu vazhinji, inoshandisa tekinoroji yeOFDM, nepo WiFi 6 inoshandisa tekinoroji yeOFDMA.Musiyano uripo pakati pemaitiro maviri aya unogona kuratidzwa zvine graphic:
Mumugwagwa INOGONA kugarisa mota imwe chete, OFDMA inogona panguva imwe chete kufambisa nzvimbo dzakawanda dzakafanana, ichibvisa mitsetse uye kusangana, KUKWITSA KUNYANYA UYE kuderedza latency.OFDMA inokamura chiteshi chisina waya kuita akawanda subchannels mune frequency domain, kuitira kuti vashandisi vakawanda panguva imwe chete vatumire data mukuwirirana munguva yega yega, izvo zvinovandudza kushanda uye kuderedza kunonoka kwemutsetse.
WIFI 6 yave kurova kubva payakatangwa, sezvo vanhu vari kuda kuwanda uye mawaya epamba network.Zvinopfuura 2 bhiriyoni Wi-Fi 6 zviteshi zvakatumirwa mukupera kwa2021, zvichiverengera zvinopfuura makumi mashanu muzana ezvese zveWi-Fi zviteshi zvekutumira, uye iyo nhamba ichakura kusvika 5.2 bhiriyoni ne2025, sekureva kweanoongorora femu IDC.
Kunyangwe Wi-Fi 6 yakatarisana neruzivo rwemushandisi mune yakakwirira-density mamiriro, matsva ekushandisa akabuda mumakore achangopfuura ayo anoda yakakwira throughput uye latency, senge ekupedzisira-yepamusoro-tsanangudzo mavhidhiyo akadai se4K uye 8K mavhidhiyo, kushanda kure, online vhidhiyo. musangano, uye VR/AR mitambo.Tech hofori dzinoonawo matambudziko aya, uye Wi-Fi 7, iyo inopa yakanyanyisa kumhanya, hukuru hwepamusoro uye yakaderera latency, iri kutasva wave.Ngatitorei Qualcomm's Wi-Fi 7 semuenzaniso uye titaure nezve izvo Wi-Fi 7 yakagadziridzwa.
Wi-fi 7: Zvese zveLow Latency
1. Higher Bandwidth
Zvakare, tora migwagwa.Wi-fi 6 inonyanya kutsigira 2.4ghz uye 5ghz mabhendi, asi iyo 2.4ghz mugwagwa wakagovaniswa nekutanga Wi-Fi uye humwe hutambo husina waya hwakadai seBluetooth, saka inova yakanyanya kuwanda.Migwagwa ye5GHz yakakura uye haina kuwanda kupfuura pa 2.4ghz, iyo inoshandura kukurumidza kumhanya uye kuwedzera huwandu.Wi-fi 7 inototsigira 6GHz bhendi pamusoro pemabhendi maviri aya, ichiwedzera hupamhi hwechiteshi chimwe kubva paWi-Fi 6′s 160MHz kusvika 320MHz (iyo inogona kutakura zvinhu zvakawanda panguva).Panguva iyoyo, Wi-Fi 7 inenge iine peak transmission rate inopfuura 40Gbps, yakapetwa kana kupfuura Wi-Fi 6E.
2. Multi-link Access
Pamberi peWi-Fi 7, vashandisi vaigona kushandisa mugwagwa mumwe chete wakanyatsokodzera zvavanoda, asi Qualcomm's Wi-Fi 7 mhinduro inosundira miganhu yeWi-Fi zvakatonyanya: mune ramangwana, ese matatu mabhendi achakwanisa kushanda panguva imwe chete, kuderedza kuwandisa.Uye zvakare, zvichibva pane yakawanda-link basa, vashandisi vanogona kubatana kuburikidza nematanho akawanda, vachitora mukana weizvi kudzivirira kusangana.Semuenzaniso, kana paine traffic pane imwe yechiteshi, mudziyo unogona kushandisa imwe chiteshi, zvichikonzera kuderera latency.Zvichakadaro, zvichienderana nekuwanikwa kwematunhu akasiyana, iyo yakawanda-link inogona kushandisa kana maviri chiteshi mu5GHz bhendi kana musanganiswa wemachaneli maviri mu5GHz uye 6GHz mabhendi.
3. Aggregate Channel
Sezvambotaurwa pamusoro, iyo Wi-Fi 7 bandwidth yakawedzerwa kusvika 320MHz (hupamhi hwemotokari).Kune 5GHz bhendi, hapana inoenderera 320MHz bhendi, saka chete dunhu re6GHz rinogona kutsigira iyi inoenderera modhi.Neyepamusoro-bandwidth panguva imwe chete ye-multi-link basa, mabhendi maviri e-frequency anogona kuunganidzwa panguva imwe chete kuti atore kubuda kwezviteshi zviviri, kureva kuti, masaini maviri e160MHz anogona kusanganiswa kuti aite 320MHz inoshanda chiteshi (yakawedzera upamhi).Nenzira iyi, nyika yakaita seyedu, iyo isati yagovera 6GHz spectrum, inogonawo kupa chiteshi chakakwana chinoshanda kuti iwane yakanyanyisa kuburitsa mumamiriro ezvinhu akatsvikinyidzana.
4. 4K QAM
Iyo yakanyanya kurongeka modulation yeWi-Fi 6 ndeye 1024-QAM, nepo Wi-Fi 7 inogona kusvika 4K QAM.Nenzira iyi, chiyero chepamusoro chinogona kuwedzerwa kuwedzera kuburitsa uye huwandu hwedata, uye kumhanya kwekupedzisira kunogona kusvika 30Gbps, inova katatu kumhanya kweiyo ikozvino 9.6Gbps WiFi 6.
Muchidimbu, Wi-Fi 7 yakagadzirirwa kupa yakanyanyisa kumhanya, huwandu hwepamusoro, uye yakaderera latency data kutapurirana nekuwedzera huwandu hwenzira dziripo, hupamhi hwemotokari yega yega inotakura data, uye hupamhi hwenzira yekufamba.
Wi-fi 7 Inojekesa Nzira Yepamusoro-kumhanya Multi-yakabatana IoT
Sekuona kwemunyori, musimboti weiyo nyowani yeWi-Fi 7 tekinoroji haisi kungovandudza mwero wepamusoro wechinhu chimwe chete, asi zvakare kubhadhara zvakanyanya kune yakakwira-reti yekufambisa panguva imwe chete pasi pekushandiswa kwevazhinji-mushandisi. -lane yekuwana) mamiriro, ayo pasina mubvunzo anoenderana neinotevera Internet yeZvinhu nguva.Tevere, munyori achataura nezve anonyanya kubatsira iot mamiriro:
1. Industrial Internet yezvinhu
Imwe yemabhodhoro makuru eiyo iot tekinoroji mukugadzira ndeye bandwidth.Iyo yakawanda data inogona kutaurirwa kamwechete, iyo Iot inokurumidza uye inobudirira.Panyaya yekutariswa kwemhando yepamusoro muIndasitiri Internet yezvinhu, kumhanya kwenetiweki kwakakosha mukubudirira kweiyo-chaiyo-nguva maapplication.Nekubatsirwa kwe-high-speed Iiot network, zviziviso zvenguva-yechokwadi zvinogona kutumirwa munguva yekukurumidza kupindura kumatambudziko akadai semashini asingatarisirwi kukanganisa uye kumwe kukanganisa, kuvandudza zvakanyanya kugadzirwa uye kubudirira kwemakambani ekugadzira uye kuderedza mari isingakoshi.
2. Edge Computing
Nekuda kwevanhu kwekupindura nekukurumidza kwemichina yakangwara uye chengetedzo yedata yeInternet yeZvinhu iri kukwira nekukwira, cloud computing ichazove yakashongedzwa mune ramangwana.Edge computing inongoreva komputa kudivi remushandisi, izvo zvinoda kwete chete yakakwirira komputa simba padivi remushandisi, asiwo yakakwirira yakakwana yekumhanyisa data kudivi remushandisi.
3. Inonyudza AR/VR
Immersive VR inoda kuita inoenderana nekukurumidza mhinduro zvinoenderana nechaiyo-nguva zviito zvevatambi, izvo zvinoda yakanyanya kuderera kunonoka kwetiweki.Kana iwe uchigara uchipa vatambi imwe-beat inononoka mhinduro, saka kunyudzwa ndeye sham.Wi-fi 7 inotarisirwa kugadzirisa dambudziko iri uye nekumhanyisa kutorwa kweiyo inonyudza AR/VR.
4. Kuchengetedza kwakangwara
Nekuvandudzwa kwekuchengetedza kwakangwara, mufananidzo unofambiswa nemakamera akangwara uri kuramba uchiwedzera-tsanangudzo, zvinoreva kuti data rine simba rinofambiswa riri kuwedzera kukura, uye zvinodikanwa zvebandwidth uye network kumhanya zviri kuramba zvichikwira nekukwira.PaLAN, WIFI 7 ingangove ndiyo yakanakisa sarudzo.
Pakupera
Wi-fi 7 yakanaka, asi parizvino, nyika dzinoratidza maitiro akasiyana ekuti vobvumira kupinda kweWiFi mu6GHz (5925-7125mhz) bhendi sebhendi risina rezenisi.Nyika haisati yapa mutemo wakajeka pa6GHz, asi kunyangwe bhendi re5GHz riripo chete, Wi-Fi 7 inogona kuramba ichipa mwero wekutapurirana we4.3Gbps, nepo Wi-Fi 6 ichingotsigira kukurumidza kurodha kwe3Gbps. kana 6GHz bhendi iripo.Naizvozvo, zvinotarisirwa kuti Wi-Fi 7 ichaita basa rinowedzera kukosha mune yakakwirira-kumhanya maLans mune ramangwana, kubatsira akawanda uye akangwara maturusi kudzivirira kubatwa netambo.
