Empeleni, ukuqhathanisa phakathi kwe-5G esebenzayo ne-WiFi akufanele neze.Ngenxa yokuthi i-5G “iyisizukulwane sesihlanu” sohlelo lwezokuxhumana lweselula, futhi i-WiFi ihlanganisa izinguqulo eziningi “zesizukulwane” ezifana ne-802.11/a/b/g/n/ac/ad/ax, ifana nomehluko phakathi kwe-Tesla neSitimela. .

Ngobubanzi, kusukela kubukhulu obufanayo, umehluko phakathi kwesistimu yokuxhumana yeselula (XG, X=1,2,3,4,5) kanye ne-Wifi esiyisebenzisa namuhla?
Umehluko phakathi kwe-XG ne-Wifi
Njengomsebenzisi, okuhlangenwe nakho kwami ukuthi i-Wifi ishibhe kakhulu kune-XG, futhi uma siziba izindleko ze-broadband enezintambo namarutha, singaze sicabange ukuthi ukusebenzisa i-wifi ukuze uxhume ku-inthanethi kumahhala.Nokho, ezimweni eziningi, amanani angabonisa kuphela izici ezithile zobuchwepheshe.Uma uthatha inethiwekhi yasekhaya encane futhi uyinwebe ezweni lonke nasemhlabeni wonke, i-XG.Kodwa kunomehluko omkhulu phakathi kwalesi sikhulu nesincane.
Ukuze sichaze umehluko phakathi kwazo, kudingeka siqale ngezimfuneko.
Umehluko wesidingo
Ukuncintisana
Endabeni ye-Wifi ne-XG, umehluko wezobuchwepheshe phakathi kwazo ufana nokuzimela kwesifunda kanye nokubeka endaweni eyodwa.Baholela embonweni wokuthi iningi lamanodi e-Wifi akhiwe ngabazimele (noma inkampani, noma idolobha), kuyilapho ama-Opharetha enza iziteshi eziyisisekelo ze-XG ezweni.
Ngamanye amazwi, ekudluliselweni kwesignali okungenantambo, ngenxa yokuthi amarutha angawodwana awaxhumani futhi abelana nge-spectrum efanayo, ukudluliswa kwedatha nge-Wifi kuyaqhudelana.Ngokuphambene, ukudluliswa kwedatha nge-XG akunakuncintisana, kuwukuhlelwa kwensiza okumaphakathi.
Ngaphansi kobuchwepheshe, ngeke sazi ukuthi uma kumpambanomgwaqo olandelayo kungazelelwe kuzobona ulayini omude wezimoto ezinamalambu abomvu angemuva phambi kwethu uma siphuma emgwaqeni.Ujantshi wesitimela ngeke ube nalolu hlobo lwenkathazo;uhlelo oluphakathi lokuthumela luthumela yonke into.
Ubumfihlo
Ngesikhathi esifanayo, i-Wifi ixhunywe ku-broadband yekhebula yangasese.Isiteshi sesisekelo se-XG sixhunywe kunethiwekhi yomgogodla Yama-Operators, ngakho-ke i-Wifi ngokuvamile inezidingo zobumfihlo futhi ayikwazi ukufinyelelwa ngaphandle kwemvume.
Ukuhamba
Ngenxa yokuthi i-Wifi ixhunywe ku-broadband yangasese, indawo yokufinyelela yekhebula yomuntu siqu ilungisiwe, futhi ulayini unezintambo.Lokhu kusho ukuthi i-wifi inesidingo esincane sokuhamba kanye nendawo encane yokumboza.Ngokuvamile kudingekile kuphela ukucabangela umthelela wejubane lokuhamba ekudluliseleni isignali, futhi ukushintsha kwamaseli akubhekwa.Kodwa-ke isiteshi sesisekelo se-XG sinezidingo zokuhamba eziphezulu kanye nokushintshwa kwamaseli, futhi izinto ezinesivinini esiphezulu njengezimoto nezitimela zidinga ukucatshangelwa.
Izidingo zobumfihlo ezincintisanayo/ezingezona ukuncintisana kanye nokuhamba zizoletha uchungechunge lomehluko kusukela ekusebenzeni, ezobuchwepheshe kanye nokuhlanganisa, ukufinyelela, i-spectrum, isivinini, njll.
Umehluko wezobuchwepheshe
1. I-Spectrum / Ukufinyelela
I-Spectrum mhlawumbe iyisicuphi esisheshayo sokuncintisana.
I-frequency spectrum esetshenziswa i-wifi ithi (2.4GHz/5G) iyi-spectrum engagunyaziwe, okusho ukuthi ayinikezwanga/indali kubantu noma izinkampani, futhi noma ubani/ibhizinisi lingasebenzisa idivayisi yalo ye-wifi ukuze liyifinyelele ngokuthanda kwayo.I-spectrum esetshenziswa i-XG iyisibukeli esinelayisense, futhi akekho omunye onelungelo lokusebenzisa lesi sibukeli ngaphandle Kwama-Opharetha athole ububanzi.
Ngakho-ke, uma uvula i-wifi yakho, uzobona uhlu olude kakhulu olungenantambo;eziningi zazo zingamarutha angu-2.4GHz.Lokhu kusho ukuthi le bhendi yefrikhwensi iminyene kakhulu, futhi kungase kube nokuphazamiseka okuningi okufana nomsindo.
Lokho kusho ukuthi uma bonke obunye ubuchwepheshe bufana, i-Wifi SNR (isilinganiso sesignali kuya kumsindo) izoba ngaphansi kumaselula akule bhendi, okuzophumela embozweni ye-wifi encane kanye nokudlulisela.Ngenxa yalokho, izimiso zamanje ze-wifi zinwebela ku-5GHz, 60GHz namanye amabhendi efrikhwensi yokuphazamiseka okuphansi.
Ngohlu olude kangaka, futhi ibhendi ye-frequency ye-wifi ilinganiselwe, kuzoba nokuncintisana kwezinsiza zesiteshi.Ngakho-ke, iphrothokholi yokuxhumana yomoya ewumongo ye-wifi yi-CSMA/CA (Isithwali sizwa ukufinyelela okuningi/ukugwema ukushayisana).ikwenza lokhu ngokubheka isiteshi ngaphambi kokuthumela nokulinda isikhathi esingahleliwe uma isiteshi simatasa.Kodwa ukutholwa akusona isikhathi sangempela, ngakho-ke kusengenzeka ukuthi kube nemizila emibili ndawonye ukuze kutholwe i-spectrum engenzi lutho ndawonye futhi ithumele idatha ngesikhathi esisodwa.Bese kuba nenkinga yokushayisana, futhi indlela yokudlulisela kabusha izosetshenziselwa ukudlulisa futhi.
Ku-XG, ngenxa yokuthi isiteshi sokufinyelela sabelwe isiteshi esiyisisekelo futhi izici zokuphazamiseka zicatshangelwa ku-algorithm yokwabiwa, indawo yokufakwa kwesiteshi esiyisisekelo esinobuchwepheshe obufanayo izoba nkulu.Ngesikhathi esifanayo, ekudlulisweni kwesignali ngaphambili, i-XG inikezwe "umugqa" wesiteshi esizinikezele, ngakho-ke asikho isidingo sokutholwa kwesiteshi ngaphambi kokudluliselwa, futhi izidingo zokudluliselwa kabusha kokushayisana nazo ziphansi kakhulu.
Omunye umehluko obalulekile mayelana nokufinyelela ukuthi i-XG ayinalo igama eliyimfihlo ngenxa yokuthi Abasebenzisi badinga ukufinyelela kusayithi eligcwele, futhi basebenzisa umazisi okukhadi le-SIM futhi bakhokhise ngesango elikhokhelwayo.I-wifi yangasese ivamise ukudinga iphasiwedi.
2.Ukuhlanganisa
Njengoba kushiwo ngaphambili, ukufakwa kwe-wifi ngokuvamile kuphansi, uma kuqhathaniswa, isiteshi esiyisisekelo sizoba nokufakwa okukhulu kakhulu ngenxa yokuthi amandla aso okudlulisela aphezulu kanye nokuphazamiseka kwebhendi yefrikhwensi ephansi.
Isivinini senethiwekhi singase sithintwe izinto eziningi kakhulu, ngeke sixoxe ngesivinini se-wifi ne-XG, empeleni, kungenzeka.
Kodwa esakhiweni senkampani, isibonelo, uma ufuna ukunweba ukufakwa kwakho kwe-wifi ukuze uhlukanise abasebenzi bakho.Irutha eyodwa engenantambo ngokuqinisekile ngeke isebenze.Irutha eyodwa engenantambo emboza isakhiwo senkampani izoweqa nakanjani amandla omsakazo ashiwo yizwe.Ngakho-ke, inethiwekhi ehlanganisiwe yama-routers amaningi iyadingeka, isibonelo, i-router engenantambo inesibopho segumbi elilodwa, kanti amanye ama-routers asebenzisa igama elifanayo futhi asebenze ndawonye ukuze enze inethiwekhi engenazintambo kulo lonke isakhiwo.
Sonke siyazi ukuthi uhlelo lokuthatha izinqumo lwenodi eyodwa luwuhlelo olusebenza kahle kakhulu.okungukuthi, uma kukhona ukusebenzisana kwama-multi-node kunethiwekhi engenantambo, indlela ephumelela kakhulu iwukuba nesilawuli esibanzi senethiwekhi ukuze sisize isimiso somzila ngamunye futhi sinikeze izinsiza zesikhathi/isikhala/i-spectrum.
Kunethiwekhi ye-wifi (WLAN), i-AP ehlanganisiwe (iphoyinti lokufinyelela) ne-AC (Isilawuli Sokufinyelela) kumzila wasekhaya ziyahlukaniswa.I-AC ilawula inethiwekhi futhi yabe izinsiza.
Hhayi-ke, uma singayinweba kancane.
Kuze kufike ezweni lonke, i-AC eyodwa ngokusobala ayanele isivinini sokucubungula idatha, isifunda ngasinye sidinga i-AC efanayo, futhi i-AC ngayinye nayo idinga ukusebenzisana ukuze ixhumane.Lokhu kwakha inethiwekhi ewumgogodla.
Futhi i-AP ngayinye yenza inethiwekhi yokufinyelela kumsakazo.
Inethiwekhi yokuxhumana yeselula ye-opharetha yakhiwe ngobudoda inethiwekhi ewumongo kanye nenethiwekhi yokufinyelela.
Njengoba kukhonjisiwe ngezansi, ingabe lokhu kuyefana nenethiwekhi yomzila ongenantambo (WLAN)?
Kusukela kumzila owodwa, ukuya kumarutha amaningi ezingeni lenkampani, noma ukuya ekufakweni kwesiteshi okuyisisekelo ezingeni likazwelonke, lokhu mhlawumbe umehluko nokuxhumana phakathi kwe-wifi ne-XG.
