Ngaba ufuna ukwazi ukuba isoka lakho liyakuthanda ukudlala imidlalo yekhompyutha? Makhe ndikunike icebiso, ungajonga ukuba ikhompyutha yalo iqhagamshelene ngentambo yenethiwekhi okanye akunjalo. Kuba abafana baneemfuno eziphezulu kwisantya senethiwekhi kunye nokulibaziseka xa bedlala imidlalo, kwaye uninzi lwe-WiFi yasekhaya yangoku ayinakukwenza oku nokuba isantya senethiwekhi ye-broadband sikhawuleza ngokwaneleyo, ngoko ke abafana abadla ngokudlala imidlalo badla ngokukhetha ukufikelela kwi-broadband ukuqinisekisa indawo yenethiwekhi ezinzileyo nekhawulezayo.
Oku kukwabonakalisa iingxaki zonxibelelwano lwe-WiFi: ukubambezeleka okuphezulu kunye nokungazinzi, okubonakala ngakumbi kwimeko yabasebenzisi abaninzi ngaxeshanye, kodwa le meko iya kuphucuka kakhulu ngokufika kwe-WiFi 6. Oku kungenxa yokuba i-WiFi 5, esetyenziswa ngabantu abaninzi, isebenzisa iteknoloji ye-OFDM, ngelixa i-WiFi 6 isebenzisa iteknoloji ye-OFDMA. Umahluko phakathi kwezi ndlela zimbini ungabonakaliswa ngokwemizobo:
Kwindlela enokuthwala imoto enye kuphela, i-OFDMA inokudlulisa ngaxeshanye ii-terminals ezininzi ngaxeshanye, isusa imigca kunye nokuxinana, iphucula ukusebenza kakuhle kwaye inciphise ukubambezeleka. I-OFDMA yahlula itshaneli engenazingcingo ibe zii-subchannels ezininzi kwi-frequency domain, ukuze abasebenzisi abaninzi bakwazi ukuhambisa idatha ngaxeshanye ngaxeshanye kwixesha ngalinye, nto leyo ephucula ukusebenza kakuhle kwaye inciphise ukulibaziseka kokuma emgceni.
I-WIFI 6 ibe yimpumelelo ukusukela oko yasungulwa, njengoko abantu befuna iinethiwekhi zasekhaya ezingenazingcingo ezingaphezulu nangakumbi. Iiterminal ze-Wi-Fi 6 ezingaphezu kweebhiliyoni ezi-2 zathunyelwa ekupheleni kuka-2021, ezibalelwa ngaphezulu kwe-50% yazo zonke iiterminal ze-Wi-Fi, kwaye elo nani liza kukhula liye kwi-5.2 yeebhiliyoni ngo-2025, ngokutsho kwenkampani yohlalutyo i-IDC.
Nangona i-Wi-Fi 6 igxile kumava omsebenzisi kwiimeko ezixineneyo, kuye kwavela usetyenziso olutsha kwiminyaka yakutshanje olufuna i-throughput ephezulu kunye ne-latency, njengeevidiyo ze-ultra-high-definition ezifana neevidiyo ze-4K kunye ne-8K, ukusebenza kude, ii-video conferencing kwi-intanethi, kunye nemidlalo ye-VR/AR. Iingcali zobuchwepheshe nazo ziyazibona ezi ngxaki, kwaye i-Wi-Fi 7, enika isantya esiphezulu, amandla aphezulu kunye ne-latency ephantsi, iqhuba kakuhle. Masithathe i-Wi-Fi 7 yeQualcomm njengomzekelo kwaye sithethe ngento i-Wi-Fi 7 eyiphuculileyo.
I-Wi-fi 7: Konke ngenxa yoBude obuphantsi
1. I-bandwidth ephezulu
Kwakhona, thatha iindlela. I-Wi-fi 6 ixhasa ikakhulu iibhendi ze-2.4ghz kunye ne-5ghz, kodwa indlela ye-2.4ghz yabelwana ngayo yi-Wi-Fi yakudala kunye nezinye iiteknoloji ezingenazingcingo ezifana ne-Bluetooth, ngoko ke ixinene kakhulu. Iindlela ezikwi-5GHz zibanzi kwaye azixinene kangako kune-2.4ghz, nto leyo ethetha isantya esikhawulezayo kunye nomthamo omkhulu. I-Wi-fi 7 ixhasa nebhendi ye-6GHz ngaphezulu kwezi bhendi zimbini, yandisa ububanzi betshaneli enye ukusuka kwi-Wi-Fi 6's 160MHz ukuya kwi-320MHz (enokuthwala izinto ezininzi ngexesha). Ngelo xesha, i-Wi-Fi 7 iya kuba nesantya esiphezulu sokudlulisela esingaphezulu kwe-40Gbps, esiphindwe kane kune-Wi-Fi 6E.
2. Ukufikelela kwiikhonkco ezininzi
Ngaphambi kwe-Wi-Fi 7, abasebenzisi babenokusebenzisa indlela enye kuphela efanela iimfuno zabo, kodwa isisombululo se-Qualcomm's Wi-Fi 7 sityhala imida ye-Wi-Fi nangakumbi: kwixesha elizayo, zonke iibhendi ezintathu ziya kukwazi ukusebenza ngaxeshanye, zinciphise ukuxinana. Ukongeza, ngokusekwe kumsebenzi we-multi-link, abasebenzisi banokuqhagamshela kwiitshaneli ezininzi, besebenzisa oku ukuze baphephe ukuxinana. Umzekelo, ukuba kukho ithrafikhi kwenye yeetshaneli, isixhobo singasebenzisa esinye itshaneli, nto leyo ekhokelela ekubeni kubekho i-latency ephantsi. Okwangoku, kuxhomekeke ekufumanekeni kwemimandla eyahlukeneyo, i-multi-link ingasebenzisa iitshaneli ezimbini kwibhendi ye-5GHz okanye indibaniselwano yeetshaneli ezimbini kwi-5GHz kunye ne-6GHz bands.
3. Itshaneli edibeneyo
Njengoko kukhankanyiwe apha ngasentla, i-bandwidth ye-Wi-Fi 7 yonyusiwe ukuya kwi-320MHz (ububanzi besithuthi). Kwibhendi ye-5GHz, akukho bhendi ye-320MHz eqhubekayo, ngoko ke yingingqi ye-6GHz kuphela enokuxhasa le ndlela eqhubekayo. Ngomsebenzi we-bandwidth ephezulu ngaxeshanye we-multi-link, iibhendi ezimbini ze-frequency zinokuhlanganiswa ngaxeshanye ukuze kuqokelelwe i-throughput yezi channels zimbini, oko kukuthi, imiqondiso emibini ye-160MHz inokudityaniswa ukwenza itshaneli esebenzayo ye-320MHz (ububanzi obubanzi). Ngale ndlela, ilizwe elifana nelethu, elingakabelani i-spectrum ye-6GHz, linokubonelela ngetshaneli ebanzi ngokwaneleyo yokufikelela kwi-throughput ephezulu kakhulu kwiimeko ezixineneyo.
4. 4K QAM
Ulawulo oluphezulu lwe-Wi-Fi 6 yi-1024-QAM, ngelixa i-Wi-Fi 7 inokufikelela kwi-4K QAM. Ngale ndlela, izinga eliphezulu linokwandiswa ukuze kwandiswe umthamo wokudlulisa idatha kunye nomthamo wayo, kwaye isantya sokugqibela sinokufikelela kwi-30Gbps, esiphindwe kathathu kunesantya se-9.6Gbps ye-WiFi 6 yangoku.
Ngamafutshane, i-Wi-Fi 7 yenzelwe ukubonelela ngesantya esiphezulu kakhulu, amandla aphezulu, kunye nokudluliselwa kwedatha okukhawulezayo ngokunyusa inani leendlela ezikhoyo, ububanzi besithuthi ngasinye esithutha idatha, kunye nobubanzi bendlela yokuhamba.
I-Wi-fi 7 ivula indlela ye-IoT ekhawulezayo eqhagamshelwe kwiindidi ezininzi
Ngokoluvo lombhali, eyona nto iphambili kwitekhnoloji entsha ye-Wi-Fi 7 ayikokuphucula nje kuphela izinga eliphezulu lesixhobo esinye, kodwa kukwanika ingqalelo ngakumbi kwisantya esiphezulu sokudluliselwa ngaxeshanye phantsi kokusetyenziswa kweemeko zabasebenzisi abaninzi (ukufikelela kwiindlela ezininzi), nto leyo ngokungathandabuzekiyo ihambelana nexesha elizayo le-Intanethi yezinto. Okulandelayo, umbhali uza kuthetha ngeemeko ze-iot eziluncedo kakhulu:
1. I-Intanethi yezinto zeShishini
Enye yezona ngxaki zinkulu zobuchwepheshe be-iot kwimveliso yi-bandwidth. Okukhona idatha eninzi inokudluliselwa ngaxeshanye, kokukhona i-Iiot iya kukhawuleza kwaye isebenze kakuhle. Kwimeko yokubeka esweni umgangatho kwi-Industrial Internet of Things, isantya senethiwekhi sibaluleke kakhulu kwimpumelelo yezicelo zexesha langempela. Ngoncedo lwenethiwekhi ye-Iiot ekhawulezayo, izilumkiso zexesha langempela zinokuthunyelwa ngexesha ukuze kuphendulwe ngokukhawuleza kwiingxaki ezinje ngokusilela koomatshini okungalindelekanga kunye nokunye ukuphazamiseka, okuphucula kakhulu imveliso kunye nokusebenza kakuhle kwamashishini okuvelisa kunye nokunciphisa iindleko ezingeyomfuneko.
2. Ikhompyutha ye-Edge
Njengoko imfuno yabantu yokusabela ngokukhawuleza koomatshini abakrelekrele kunye nokhuseleko lwedatha lwe-Intanethi yezinto lusiya lusanda, i-cloud computing iya kuthanda ukubekelwa ecaleni kwixesha elizayo. I-Edge computing ibhekisa nje kwi-computing kwicala lomsebenzisi, engadingi kuphela amandla aphezulu e-computing kwicala lomsebenzisi, kodwa ikwafuna nesantya esiphezulu sokudlulisa idatha kwicala lomsebenzisi.
3. I-AR/VR enzulu
I-VR enzulu kufuneka yenze impendulo ekhawulezileyo ehambelanayo ngokwezenzo zabadlali ngexesha langempela, nto leyo efuna ukulibaziseka okukhulu kwenethiwekhi. Ukuba uhlala unika abadlali impendulo ecothayo, ngoko ukuntywiliselwa kubuxoki. I-Wi-fi 7 kulindeleke ukuba isombulule le ngxaki kwaye ikhawulezise ukwamkelwa kwe-AR/VR enzulu.
4. Ukhuseleko olukrelekrele
Ngophuhliso lokhuseleko olukrelekrele, umfanekiso odluliselwa ziikhamera ezikrelekrele uya usiba nentsingiselo ephezulu, nto leyo ethetha ukuba idatha eguquguqukayo ethunyelwayo iya ikhula, kwaye iimfuno ze-bandwidth kunye nesantya senethiwekhi nazo ziya ziphakama. Kwi-LAN, i-WIFI 7 mhlawumbi yeyona ndlela ilungileyo.
Ekugqibeleni
I-Wi-fi 7 ilungile, kodwa okwangoku, amazwe abonisa izimvo ezahlukeneyo malunga nokuba kufuneka kuvunyelwe ukufikelela kwi-WiFi kwibhendi ye-6GHz (5925-7125mhz) njengebhendi engenalayisenisi. Eli lizwe alikaniki mgaqo-nkqubo ucacileyo kwi-6GHz, kodwa nokuba kukho ibhendi ye-5GHz kuphela ekhoyo, i-Wi-Fi 7 isenokubonelela ngesantya esiphezulu sokudlulisa i-4.3Gbps, ngelixa i-Wi-Fi 6 ixhasa kuphela isantya esiphezulu sokukhuphela se-3Gbps xa ibhendi ye-6GHz ifumaneka. Ke ngoko, kulindeleke ukuba i-Wi-Fi 7 idlale indima ebaluleke ngakumbi kwi-Lans ekhawulezayo kwixesha elizayo, inceda izixhobo ezininzi ezikrelekrele ukuba zingabanjwa yintambo.
