Ngaba uyafuna ukwazi ukuba isithandwa sakho siyathanda ukudlala imidlalo yekhompyuter? Mandabelane nawe ngengcebiso, ungajonga ikhompyuter yakhe inethiwekhi yentambo yonxibelelwano okanye hayi. Ngenxa yokuba amakhwenkwe aneemfuno eziphezulu kwisantya womnatha kunye nokulibaziseka xa udlala imidlalo, kwaye uninzi lweWiFi yangoku yasekhaya ayinakukwenza oku nokuba isantya senethiwekhi yebroadband sikhawuleza ngokwaneleyo, ngoko ke amakhwenkwe adla ngokudlala imidlalo adla ngokukhetha ukufikelela kweengcingo kwi-broadband. qinisekisa indawo yenethiwekhi ezinzileyo nekhawulezayo.
Oku kukwabonisa iingxaki zoxhumo lwe-WiFi: i-latency ephezulu kunye nokungazinzi, ezicacileyo ngakumbi kwimeko yabasebenzisi abaninzi ngexesha elinye, kodwa le meko iya kuphuculwa kakhulu ngokufika kwe-WiFi 6. Oku kungenxa yokuba i-WiFi 5, leyo isetyenziswa ngabantu abaninzi, isebenzisa ubuchwepheshe beOFDM, ngelixa iWiFi 6 isebenzisa ubuchwepheshe beOFDMA. Umahluko phakathi kwezi ndlela zimbini zobuchule unokuzotywa:
Kwindlela ENOKUHLANGANISA imoto enye kuphela, i-OFDMA inokuhambisa ngaxeshanye iitheminali ezininzi ngokunxuseneyo, ishenxise imigca kunye nokuxinana, UKUPHUCULA UKUSEBENZA KWAYE kuncitshiswe ukubambezeleka. I-OFDMA yahlula ijelo elingenazingcingo kwiitshaneli ezininzi kwi-domain frequency, ukuze abasebenzisi abaninzi ngaxeshanye badlulise idatha ngokufana ngexesha ngalinye, okuphucula ukusebenza kakuhle kunye nokunciphisa ukulibaziseka komgca.
I-WIFI 6 iye yatshatyalaliswa ukususela ekusungulweni kwayo, njengoko abantu befuna uthungelwano lwasekhaya olungenazingcingo. Ngaphezulu kwe-2 yeebhiliyoni ze-Wi-Fi 6 iitheminali zathunyelwa ekupheleni kuka-2021, ezenza ngaphezu kwe-50% yazo zonke izinto ezithunyelwa kwi-terminal ye-Wi-Fi, kwaye elo nani liya kukhula ukuya kwi-5.2 yezigidigidi ngo-2025, ngokutsho komhlalutyi we-IDC.
Nangona i-Wi-Fi 6 igxininise kumava omsebenzisi kwiimeko zoxinaniso oluphezulu, izicelo ezitsha ziye zavela kwiminyaka yakutshanje ezifuna i-throughput ephezulu kunye ne-latency, njengevidiyo ze-ultra-high-definition ezifana neevidiyo ze-4K kunye ne-8K, ukusebenza kude, ividiyo ye-intanethi. inkomfa, kunye nemidlalo yeVR/AR. Iingxilimbela zobuchwephesha nazo zibona ezi ngxaki, kwaye iWi-Fi 7, ebonelela ngesantya esiphezulu, umthamo ophakamileyo kunye ne-latency ephantsi, ikhwele i-wave. Makhe sithathe i-Wi-Fi 7 ye-Qualcomm njengomzekelo kwaye sithethe malunga nokuba i-Wi-Fi 7 iphucule ntoni.
I-Wi-fi 7: Yonke I-Latency ePhantsi
1. Ububanzi obuphezulu
Kwakhona, thatha iindlela. I-Wi-fi 6 ixhasa ubukhulu becala i-2.4ghz kunye ne-5ghz band, kodwa indlela ye-2.4ghz kwabelwane ngayo yi-Wi-Fi yokuqala kunye nobunye ubuchwepheshe obungenazingcingo obufana neBluetooth, ngoko iba yingxinano kakhulu. Iindlela kwi-5GHz zibanzi kwaye zincinci kune-2.4ghz, eziguqulela kwizantya ezikhawulezayo kunye nomthamo ongaphezulu. I-Wi-fi 7 ide ixhase ibhendi ye-6GHz phezu kwala maqela mabini, ukwandisa ububanzi betshaneli enye ukusuka kwi-Wi-Fi 6′s 160MHz ukuya ku-320MHz (enokuthwala izinto ezininzi ngexesha). Ngelo xesha, i-Wi-Fi 7 iya kuba nesantya esiphezulu sokuhanjiswa kwe-40Gbps, ngokuphindwe kane kune-Wi-Fi 6E.
2. UFikelelo lwamakhonkco amaninzi
Ngaphambi kwe-Wi-Fi 7, abasebenzisi banokusebenzisa kuphela indlela enye efanele iimfuno zabo, kodwa isisombululo se-Qualcomm se-Wi-Fi 7 sityhala imida ye-Wi-Fi nangakumbi: kwixesha elizayo, onke amaqela amathathu aya kukwazi ukusebenza ngaxeshanye, ukunciphisa ukuxinana. Ukongezelela, ngokusekelwe kumsebenzi we-multi-link, abasebenzisi banokudibanisa ngeendlela ezininzi, basebenzise oku ukuze bagweme ukuxinana. Umzekelo, ukuba kukho itrafikhi kwenye yezitshaneli, isixhobo sinokusebenzisa elinye itshaneli, nto leyo ekhokelela ekubambeni kwexesha elisezantsi. Okwangoku, kuxhomekeke ekufumanekeni kwemimandla eyahlukeneyo, i-multi-link inokusebenzisa iitshaneli ezimbini kwibhendi ye-5GHz okanye indibaniselwano yamajelo amabini kwi-5GHz kunye ne-6GHz band.
3. Ijelo elidityanisiweyo
Njengoko kukhankanyiwe ngasentla, i-Wi-Fi 7 bandwidth inyuswe ukuya kwi-320MHz (ububanzi bemoto). Kwibhendi ye-5GHz, akukho bhendi ye-320MHz eqhubekayo, ngoko ngummandla we-6GHz kuphela onokuxhasa le modi eqhubekayo. Ngomsebenzi we-high-bandwidth ngexesha elinye le-multi-link ye-multi-link, iibhendi ze-frequency ezimbini zingadityaniswa ngexesha elifanayo ukuqokelela i-throughput yamajelo amabini, oko kukuthi, izibonakaliso ezimbini ze-160MHz zinokudibaniswa ukwenza i-channel esebenzayo ye-320MHz (ububanzi obandisiweyo). Ngale ndlela, ilizwe elifana nelethu, elingekawabi i-6GHz spectrum, linokubonelela ngejelo elibanzi elaneleyo lokufikelela kwimveliso ephezulu kakhulu kwiimeko ezixineneyo.
4. 4K QAM
Eyona ndlela iphezulu yokumodareyitha ye-Wi-Fi 6 yi-1024-QAM, ngelixa i-Wi-Fi 7 inokufikelela kwi-4K QAM. Ngale ndlela, isantya esiphezulu sinokunyuswa ukwandisa umthamo kunye nomthamo wedatha, kwaye isantya sokugqibela sinokufikelela kwi-30Gbps, okuphindwe kathathu isantya se-9.6Gbps WiFi 6 yangoku.
Ngamafutshane, i-Wi-Fi 7 yenzelwe ukubonelela ngesantya esiphezulu kakhulu, umthamo ophezulu, kunye nokuhanjiswa kwedatha ye-latency ephantsi ngokunyusa inani lemizila ekhoyo, ububanzi besithuthi ngasinye esihambisa idatha, kunye nobubanzi bendlela yokuhamba.
I-Wi-fi 7 Icacisa iNdlela ye-IoT enesantya esiphezulu esine-Multi-connected
Ngokombono wombhali, undoqo wobuchwephesha obutsha be-Wi-Fi 7 ayikona nje ukuphucula izinga lencopho yesixhobo esinye, kodwa nokunika ingqwalasela engakumbi kwizinga eliphezulu lokuhambisa ngaxeshanye phantsi kokusetyenziswa kwabasebenzisi abaninzi (abaninzi). -indlela yokufikelela) iimeko, ngokungathandabuzekiyo ezihambelana ne-Intanethi yeZinto ezizayo. Okulandelayo, umbhali uya kuthetha ngezona meko ziluncedo kakhulu ze-iot:
1. I-Intanethi ye-Intanethi yeZinto
Enye yeengxaki ezinkulu zetekhnoloji ye-iot kwimveliso yi-bandwidth. Idatha eninzi enokunxibelelana ngokukhawuleza, i-Iiot iya kuba ngokukhawuleza nangempumelelo. Kwimeko yokuqinisekiswa komgangatho kwi-Intanethi ye-Industrial yeZinto, isantya sothungelwano sibaluleke kakhulu kwimpumelelo yezicelo zexesha langempela. Ngoncedo lwenethiwekhi ye-Iiot ye-high-speed, izilumkiso zexesha langempela zingathunyelwa ngexesha lokuphendula ngokukhawuleza kwiingxaki ezifana nokungaphumeleli komatshini okungalindelekanga kunye nokunye ukuphazamiseka, ukuphucula kakhulu ukuveliswa kunye nokusebenza kakuhle kwamashishini okuvelisa kunye nokunciphisa iindleko ezingeyomfuneko.
2. Edge Computing
Ngemfuno yabantu yokuphendula ngokukhawuleza koomatshini abakrelekrele kunye nokhuseleko lwedatha ye-Intanethi yeZinto iya inyuka kwaye iphezulu, i-computing yamafu iya kuthambekela ekujongelwe phantsi kwixesha elizayo. I-Edge computing ibhekisela kwi-computing kwicala lomsebenzisi, engafuni kuphela amandla aphezulu ekhompyutheni kwicala lomsebenzisi, kodwa kunye nesantya esiphezulu esaneleyo sokuhanjiswa kwedatha kwicala lomsebenzisi.
3. I-AR/VR entywilayo
I-VR ye-Immersive idinga ukwenza impendulo ehambelanayo ngokukhawuleza ngokwezenzo zexesha langempela zabadlali, ezifuna ukulibaziseka okuphantsi kakhulu kwenethiwekhi. Ukuba usoloko ukunika abadlali impendulo ecothayo-beat enye, ngoko ukuntywiliselwa bubuqhophololo. I-Wi-fi 7 kulindeleke ukuba isombulule le ngxaki kwaye ikhawulezise ukwamkelwa kwe-AR/VR entywilayo.
4. Ukhuseleko oluhlakaniphile
Ngophuhliso lokhuseleko olukrelekrele, umfanekiso osasazwa ziikhamera ezikrelekrele uya usiba ngakumbi nangaphezulu, nto leyo ethetha ukuba idatha eguquguqukayo edluliswayo iya ikhula kwaye ikhula, kwaye iimfuno zebhanwidth kunye nesantya sothungelwano nazo ziya ziphezulu nangaphezulu. Kwi-LAN, i-WIFI 7 mhlawumbi yeyona ndlela ilungileyo.
Ekugqibeleni
I-Wi-fi 7 ilungile, kodwa okwangoku, amazwe abonisa izimo zengqondo ezahlukeneyo malunga nokuvumela ukufikelela kwi-WiFi kwi-6GHz (5925-7125mhz) njengebhendi engavumelekanga. Ilizwe alikanikezeli umgaqo-nkqubo ocacileyo kwi-6GHz, kodwa nangona ibhendi ye-5GHz ifumaneka kuphela, i-Wi-Fi 7 isenokubonelela ngesantya esiphezulu sothumelo lwe-4.3Gbps, ngelixa i-Wi-Fi 6 ixhasa kuphela isantya esiphezulu sokukhuphela i-3Gbps. xa ibhendi ye-6GHz ikhona. Ngoko ke, kulindeleke ukuba i-Wi-Fi 7 iya kudlala indima ebalulekileyo kwi-high-speed Lans kwixesha elizayo, inceda izixhobo ezihlakaniphile ngakumbi ukuba ziphephe ukubanjwa yintambo.
