I-5G isebenza njani?
Imigangatho ye-5G ayinakunyiswa nje okwangoku kwaye ababoneleli ngeenkonzo abayi kusebenzisa i-teknoloji efanayo ukuphumeza i-5G, ngoko kunzima ukusho ngokuchanekileyo indlela eya kusebenza ngayo yonke inkampani kwilizwe ngalinye.
Ngokomzekelo, kwezinye iimeko, i-5G iya kusasaza idatha kwibala ehlukileyo ngokupheleleyo kuneenethiwekhi ezikhoyo. Uluhlu oluphezulu lwamagagasi lubizwa ngokuba ngamaza angama-millimeter, asebenza kwi-30 GHz ukuya ku-300 GHz (ububanzi bee-intanethi basebenzisa amaqela angaphantsi kwe-6 GHZ).
Yintoni eyenza oku kubalulekileyo kukuba endaweni yezixhobo ezininzi ezikwahlula isikhala esincinane kule ndawo, ziya kukwazi "ukusabalalisa" kuloo mgca kwaye zisebenzisa i-bandwidth engaphezulu, oku kuthetha ukukhawuleza ngokukhawuleza kunye nokunciphisa ukuxhomekeka.
Nangona kunjalo, ngelixa ama-waves aphezulu angakwazi ukuqhuba idatha engaphezulu, abanako ukusasaza ukuya kwezantsi, kungenxa yoko abanye ababoneleli, ngokukodwa i-T-Mobile, baya kuhambisa i-5G kwi-spectrum 600 MHz ukuqala, kwaye mhlawumbi ezinye amaqela njengoko ixesha liqhubeka.
Ababoneleli abasebenzisa iifom ephakamileyo bangadinga ukubeka izitishi ezincinci ezingenazintambo phakathi kwama-5G kwiinqaba zokuphinda ukuphinda idatha ukwenzela ukubonelela ngesantya se-5G ngelixa elifanayo. Esikhundleni sokusasaza yonke indawo ukufikelela kwizixhobo ezikufuphi, ezi zikhululo ziya kusebenzisa okubizwa ngokuba yi- beamforming ukuhambisa imiqondiso kwiithagethi ezithile.
Olu hlobo lokuseta lufanele luvumele ukuthunyelwa ngokukhawuleza kungekhona nje ngokuba kuya kuba nenani lezitishi ukunceda ukudlulisela idatha kwisantya esiphezulu, kodwa kuba izibonakaliso aziyi kudingeka ukuba zihambele kude zifikelele kwezinye iifowuni. Ukunxibelelana kwefowuni kuya kusetyenziso oluya kuvumela ukuba kuluhlu oluphantsi.
Emva kokuba u-5G ulapha kwaye ufumaneke ngokubanzi, kunokwenzeka ukuba kuya kuba ngowokugqibela ukuqhubela phambili kwiintanethi. Esikhundleni sesithuba se-6G okanye i-7G kamva, sinokuthi sinamathele kwi-5G kodwa sibe nokuphucula okongeziweyo kwixesha.
Uza Kuvela nini 5G?

5G Iinkcazo: Ixabiso leDatha, uLatency, & amp; Kaninzi
I-5G ifuna ukuphucula imimandla emininzi yokunxibelelana ngomnxeba, ukususela ngokukhawuleza ungayilanda kwaye uyilayishe idatha kwinani lamadivaysi anokuxhuma kwi-intanethi ngexesha elinye.
Ixabiso leDatha
Le yile imfuno emancinci yee-5G eziphezulu zeerata zerhafu. Ngamanye amazwi, yinto encinane yokukhuphela kunye nokulayishwa kwejubane ukuba isalathisi ngasinye se-5G simele sixhase, kodwa sinokutshintsha kwezinye iimeko.
- Ukukhuphela: 20 Gb / s (2.5 GB / s)
- Layisha: 10 Gb / s (1.25 GB / s)
Amanani angentla apha yintoni isitishi ngasinye sendawo kufuneka sixhase kodwa oko akuthethi ukuba yiyiphi idilesi yakho eya kuba nakho. Esi santya sikwahlukana phakathi kwabo bonke abasebenzisi abadibene kwisitishi esisiseko esisodwa, okwenza la maxabiso ayenze ngakumbi kumsebenzisi ngamnye:
- Landa: 100 Mb / s (12.5 MB / s)
- Layisha: 50 Mb / s (6.25 MB / s)
Ngeemitha ezi-5G, unokukhuphela i-movie ye-3 GB kwifowuni kwiminithi emine, okanye ulayishe ividiyo ye-1 GB kwi-YouTube ngaphantsi kwemizuzu emithathu.
Ukuthelekisa, umlinganiselo wesantya wokulanda umthwalo wesigxina we-Speedtest.net ngo-2017, kubasebenzisi base-United States, wawungama-22 Mbps - ngaphezu kwexesha eliphindwe kane kunezinto ezicetywayo ngu-5G.
Uxinano loxhumo
Kwinqanaba elincinci, i-5G iya kuxhasa izixhobo ezizigidi ezi-1 nganye kwiikhilomitha ezili-0.386. Oku kuthetha ukuba ngaphakathi kwesixa semali, u-5G uza kukwazi ukudibanisa i-million million okanye ezininzi izixhobo kwi-intanethi ngexesha elinye.
Olu hlobo lwesimo lunokubonakala lukhuni ukucinga ngokucinga ngezixeko ezinobuninzi bemihlali (njengamaManila, ePhilippines, naseMumbai, eIndiya) kuphela kubamba abantu abangama-70 000 ukuya kwi-110,000 kwiiyhilomitha nganye.
Nangona kunjalo, i-5G ayidingi ukuxhasa eyodwa okanye izixhobo zombini ngomntu ngamnye kodwa kunye ne-smartwatch yomntu wonke, zonke izithuthi kwindawo enokuthi ixhunyiwe kwi-intanethi, iifowuni ze-smart door ezindlini eziseduze, kunye nawuphi na okhoyo okanye ifowuni ekhutshweyo efunekayo ukuba inethwekhi.
Ukuhamba
I-Latency ibhekisela kwixesha elidlulileyo phakathi kokuba i-cell tower ithumela idatha kwaye xa idivayisi yesiphelo (njengefowuni yakho) ifumana idatha.
I-5G idinga ubuncinci obungaphantsi kwe-4 ms ecinga ukuba iimeko ezifanelekileyo zidibeneyo, kodwa ziza kuhlahla ngaphantsi kwe-1 ms kwezinye iintlobo zonxibelelwano, iinkcukacha ezinxibelelwano ezincinci kunye ne-latency-latency (URLLC).
Ukuthelekisa, i-latency kwi-network ye-4G ingaba malunga no-50-100 ms, okwenene ngokuphindwe kabini ngokukhawuleza njengentanethi ye-3G!
Ukuhamba
Ukuhamba ngokubhekiselele kwisantya esiphezulu apho umsebenzisi angahamba khona kwaye ufumana inkonzo ye-5G.
Isigaba se-5G sichazile iiklasi ezine eziya kuncedisa, nawuphi na umntu osisigxina ongekho kumntu onesithuthi esiphezulu esifana nesitimela, ohamba nge-500 kmh (310 mph).
Kungenzeka ukuba imimandla eyahlukeneyo iya kufuna isiseko esisezantsi sesikhululo samaspala ukulungiselela ukuhamba ngokukhawuleza. Ngokomzekelo, isixeko esincinane esinobasebenzisi abanokuhamba ngeemoto neenyawo abanakho ukufumana isiseko esisiseko esifakwe kwisixeko esikhulu esinesithuthi sezithuthi.
Ukutya umbane
Ukusebenza kwamandla ngenye inxalenye ebizwa nge-5G spec. I-Interfaces izakwakhiwa ngokukhawuleza ukulungelelanisa ukusetyenziswa kwamandla ngokusekelwe kwimithwalo yabo yangoku.
Xa umsakazo ungasetyenziswanga, iya kulahla phantsi kwimeko engaphantsi kwamandla angaphantsi kwe-10 ms, uze ulungise ngokukhawuleza xa kukho amandla amaninzi.
Ulwazi olungakumbi kwi-5G
