Bonke abasebenzisi be-PC abane-tablet ngaphandle kwekhompyutha, kanye nokukwazi ukuhamba kusuka kokubili amadivaysi kunethiwekhi, ngokuqinisekile babone umehluko omkhulu ekuvinjisweni kwedatha. Uma isivinini sokulanda se-movie ku-PC ikuvumela ukuba usebenzise amaminithi ambalwa kukho, khona-ke ithebulethi enomsebenzi ofanayo izokwazi ukubhekana nokude, okuyinto engathandeki kakhulu. Ngakho-ke, kudalwe izinga elisha lokudluliselwa kwedatha ye-LTE, okuyinto edlula kakhulu abandulele bayo ekukhiqizeni. Ake sithole ukuthi izinga le-LTE kulesi sizukulwane esisha samaphilisi inikeza abanikazi bayo.
I-standard ye-LTE
Izinga lokudluliswa kwedatha ngokusebenzisa i-LTE protocol (Long Term Evolution) kuyisiqalo esikhulu emkhakheni wokuhlinzeka ngokuxhumana okusheshayo. Eqinisweni, lesi simiso sesisiteji esisha ekuthuthukiseni konke ubuchwepheshe obukhona be-UMTS ne-CDMA. I-standard standard ye-3GPP (LTE) ikhulisa kakhulu amandla abasebenzisi amaphilisi nama-smartphones . Le protocol yokudluliswa kolwazi iphumelela kangcono kunazo zonke izifanekiselo zayo, futhi ihambisana nayo ngokugcwele. Ububanzi besiteshi ngesikhathi sokuhlolwa kwakungu-1 Gbit / s (imishini enamandla kakhulu esetshenzisiwe, ebonisa ukuthi kungenzeka kanjani emisha). Eqinisweni, abasebenzisi beethebulethi ene-LTE module bangadlulisa idatha ngesivinini sika 58 Mb / s bese bamukela ngesivinini esingaphansi kuka-173 Mbps. Futhi lokhu kuyizinga elihlukile lenkonzo, okushintsha ngokuphelele umbono wekhwalithi yezinsizakalo ze-inthanethi kubasebenzisi abanokuxhumana okungenantambo.
Ithandwa kanjani i-LTE standard?
Ngokushesha, ithebhulethi enokusekela i-LTE izoba ejwayele njengamanje amadivayisi ane-Wi-Fi ubuchwepheshe. Isingeniso samasethrikhi we-LTE eRussia kuhlelwe ngo-2015. Ngenethiwekhi yesilinganiso esisha, kunikezwa ama-frequencies amaningi angu-38, okuyinto i-intanethi izotholakala kumathebulethi we-LTE standard. Kuze kube manje, ukuthunyelwa kwenethiwekhi ye-LTE kungaziqhenya ngamadolobha amakhulu kuphela, kodwa ikusasa alikude! Akukatholakalanga kakhulu, ukuxhumana kweselula kwakutholakala kuphela kubantu abambalwa, ngisho nabahola impesheni namuhla abakwazi ukukwenza ngaphandle kwamafoni weselula. Lapho ebuzwa ukuthi i-LTE iyadingeka kuthebhulethi, impendulo ingamangalisa. Uma uhlala e-megapolis, uyayidinga, futhi uma uhlala e-PGT encane noma emaphandleni, ukutholakala kwe-protocol esheshayo ngeke kukunike lutho, ngaphandle komqondo wokuthi ube negajethi ye-ultra-yesimanje.
Amathemba we-LTE technology
Ukuze uqonde ukuthi i-LTE isho ukuthini kuthebhulethi, kwanele ukucabanga ukufinyelela ku-Inthanethi ngaphandle kwemingcele, lapho amafayela amakhulu azolandwa ngaphambi kokuba umlayezo wesistimu ufike. Isici se-LTE kuthebhulethi sizokuvumela ukuba ubukele ukusakaza ividiyo ngekhwalithi ephezulu. I-TV ye-Inthanethi, i-Skype namanye amasevisi wevidiyo afanayo azoba ngokushesha. Lokhu kuqubuka okukhulu ekuthuthukiseni ukudluliswa kwedatha kumashaneli omsakazo. Izwe lonke libheke phambili ekusungulweni kwalesi simiso, amazwe amakhulu kakhulu asevele esebenzisa le nsizakalo emangalisayo, futhi abahlinzeki nabanikezeli bokuqukethwe kwiwebhu abakwazi ukwaneliswa ngokuvula amathuba amakethe amasha.
Ngokuyinhloko, labo abafisa ukuthenga idivayisi ngezinga le-LTE kufanele baqale baqiniseke ukuthi kukhona ukuthunyelwa kwale nethiwekhi ye-4G endaweni yakini. Uma kunjalo, futhi ungakwazi ukuthenga igajethi efanayo, kungani kungenjalo? Ngemuva kwalokho konke, i-intanethi okusheshayo yilezo kuphela!
