I-5G isho amadivaysi amaningi ngokusheshisa okusheshayo nokubambezeleka okuphansi kakhulu
I-5G yisizukulwane esilandelayo sobuchwepheshe bokuxhumana benethiwekhi esilandelayo kulandela i-4G. Ngokufana naso sonke isizukulwane ngaphambi kwayo, i-5G ihlose ukwenza ukukhulumisana kweselula ngokushesha futhi kunokwethenjelwa njengoba amadivaysi amaningi angena ku-intanethi.
Ngokungafani neminyaka engaphambili lapho amanethiwekhi weselula kuphela adingeka ukusekela omakhalekhukhwini ukuthi bekungokuphequlula iwebhu nokuthumela imiyalezo, manje sinezo zonke izinhlobo zamadivaysi okuthunyelwa kwe- bandwidth afana nama-Smartphones ethu okusakaza i-HD, amawashi anezinhlelo zedatha, amakhemikhali ahlale evikelekile , izimoto ezithintekayo nokushayela i-intanethi, namanye amadivaysi athembisayo afana nezinzwa zempilo kanye ne-hardware ye- AR ne- VR engathembekile.
Njengoba izigidi eziningi zamadivayisi zixhuma kuwebhu, yonke ingqalasizinda idinga ukwamukela umgwaqo ukuze ingasisekeli kuphela ukuxhuma okusheshayo kodwa futhi isebenzise kangcono ukuxhumeka okukanyekanye futhi unikezele ngokubheka kabanzi ngalawa madivayisi. Yilokho okushiwo ngu-5G.
U-5G Uhlukile Kanjani Kwenye "Gs"?
I-5G imane nje isizukulwane esilandelayo esilandelayo esilandelayo ku-4G, esithatha indawo yonke yobuchwepheshe obudala.
- I-1G ithumele izwi le-analog
- I-2G ithumele izwi ledijithali
- I-3G ifakwe idatha yeselula
- I-4G ivule indlela yokusetshenziswa kwe-intanethi yeselula
Yini Okuzokwenziwa Ku-5G?
Lokhu kungase kubonakale kuveziwe ukuthi ama-Smartphones ajwayelekile kangakanani, kodwa kuyilapho amafoni ngokuqinisekile engumdlali omkhulu ekukhulumisaneni kweselula, kungenzeka ukuthi akuyona into ebaluleke kakhulu kwinethiwekhi ye-5G.
Njengoba uzobona ngezansi, izingxenye eziyisihluthulelo nge-5G zixhunyaniswe kakhulu nge-ultra and fast delays. Nakuba lokhu kumnandi kakhulu kunoma ubani ohambisa amavidiyo kusuka efonini yakhe, kubaluleke kakhulu ezimweni lapho ukunciphisa ukubambezeleka kubaluleke kakhulu, kufana nekusasa lamadivayisi axhunyiwe.
Isicelo esisodwa singase sibe amadivayisi angokoqobo angathandwa kakhulu noma ama-headsets angempela weqiniso . Lawa madivayisi adinga inani elikhulu lomkhawulokudonsa futhi adinga ukuxhumana phezu kwe-intanethi ngokushesha ngangokunokwenzeka ukuze anikeze imiphumela yabo ehlosiwe. Noma yikuphi ukubambezeleka kungathinta kakhulu ukuthi izinto zangempela zizwa kanjani kulezo zindawo.
Okufanayo kusebenza nanoma yikuphi amanye amadivaysi adingekayo ukuthatha isinyathelo ngokushesha, njengezimoto ezizimele zokugwema ukushayisana okungazelelwe futhi ziqonde iziqondiso eziphendukayo nge-turn, i-hardware eqhutshwa kude, ne-robotic izinhlelo ezifunda noma ezihlala ezilawuli ezikude.
Ngokusho lokho, i-5G izoqhubeka isula indlela yokuxhumana okusheshisa kusuka kumadivayisi wethu wansuku zonke, njengokuthi uma kudlala, ukwenza amakholi wevidiyo, kusakaza ama-movie, ukulanda amafayela, ukwabelana nge-HD nakuma- 4K abezindaba, ukuthola izibuyekezo zethrafikhi yesikhathi sangempela, ukuvota, njll. .
I-5G ishesha kakhulu kangangokuthi ngeke nje itholakale kumadivayisi eselula. Ikwazi ukubeka ngisho nekhebula lakho ngokufinyelela okungenazintambo ezingenantambo! Bheka i- Internet yethu ye- 5G: I-High-Speed Replacement ye-Cable ye- athikili ngokuningi kulokhu.
Uzosebenza kanjani 5G?
Amazinga we-5G awaqinisekisiwe okwamanje futhi abahlinzeki bezinsizakalo ngeke basebenzise ubuchwepheshe obufanayo bokusebenzisa i-5G, ngakho-ke kunzima ukusho ukuthi kuzosebenza kanjani yonke inkampani kuzo zonke izinkampani.
Isibonelo, kwezinye izimo, i-5G izosakaza idatha ebubanzi bezinkathi ezahlukene kunamanethiwekhi atholakalayo. Lolu hlu oluphakeme lwamagagasi lubizwa ngokuthi amagagasi angu-millimeter, asebenza ku-30 GHz kuya ku-300 GHz ububanzi (amanethiwekhi wamanje asebenzisa ama-band ngaphansi kuka-6 GHZ).
Okubangela lokhu kubalulekile ukuthi esikhundleni sezinsimbi eziningi ezihlanganyela isikhala esincane kuleso sici, bazokwazi "ukusabalalisa" kulowo mzila futhi basebenzise umkhawulokudonsa owengeziwe, okusho ukushesha okusheshayo nokuncipha okuncane.
Kodwa-ke, nakuba lamagagasi aphezulu anamavolumu angathwala idatha engaphezulu, ayikwazi ukusakaza kuze kube yilowo nalowo ophansi, yingakho abanye abahlinzeki, ikakhulukazi i-T-Mobile, bazoletha i-5G ku-600 MHz i-spectrum ukuze baqale, mhlawumbe omunye amaqembu njengoba isikhathi siqhubeka.
Abahlinzeki abasebenzisa ama-frequencies aphezulu bangase badinge ukubeka iziteshi ezincane ezingenazintambo phakathi kwemibhoshongo engu-5G ukuphinda idatha ukuze kuhlinzeke ngesivinini esingu-5G ngesikhathi esifanayo kubandakanya ibanga elide. Esikhundleni semisakazo yokusakazwa kuyo yonke indawo ukuze kufinyelele amadivaysi eseduzane, lezi ziteshi cishe zizosebenzisa lokho okubizwa ngokuthi i- beamforming ukuqondisa izimpawu kumathekthi athile.
Lolu hlobo lokusetha kufanele luvumele ukuthunyelwa okusheshayo hhayi nje ngoba kuzoba nezinombolo zeziteshi ukusiza ukuhambisa idatha ngejubane eliphezulu, kodwa ngoba izibonakaliso ngeke zidingeke ukuthutha kuze kube sekufinyeleleni kwamanye amadivaysi. Lokhu kuxhumana kwedivaysi kuya kudivayisi yilokho okuzovumela ukuthi kube khona ukukhanya okuphansi okunjalo.
Uma nje u-5G ukhona futhi utholakala kabanzi, kungenzeka ukuthi kuyoba ukuthuthuka okukhulu kokugcina ekuxhumaneni kwenethiwekhi yeselula. Esikhundleni se-6G noma i-7G kamuva, singase sihlanganise nje nge-5G kodwa sithole ukuthuthukiswa okungaphezulu kwesikhathi.
Uzofika nini 5G?
Isikhathi sesikhathi sokutholakala kwezinsizakalo ze-5G akuxhomeki kuphela lapho uhlala khona kodwa nokuthi yiziphi abahlinzeka ngemisebenzi ezitholakala endaweni yakho.
Bheka nini i-5G ifika e-US? ukuthola ulwazi oluthe xaxa, noma ukutholakala kwe-5G Emhlabeni uma ungekho e-US.
Ama-5G Ama-Specs: I-Data Rate, i-Latency, & amp; Okuningi
I-5G ifuna ukuthuthukisa izindawo eziningana zokukhulumisana kweselula, kusukela ngokusheshisa ongalanda futhi ulayishe idatha kwinombolo yamadivayisi angakwazi ukuxhuma kwi-inthanethi ngesikhathi esifanayo.
Isilinganiso sedatha
Lezi yizidingo ezingenani ezilinganiselwa ku-5G wezinga lamadatha. Ngamanye amazwi, yisisindo esincane sokulanda nokulayishwa ukuthi iseli ngasinye se-5G kufanele sisekele, kodwa singashintsha kwezinye izimo.
- Landa: 20 Gb / s (2.5 GB / s)
- Layisha: 10 Gb / s (1.25 GB / s)
Izinombolo ezingenhla yilokho isiteshi ngasinye seselula kufanele sisekele kodwa lokho akusho ukuthi yilokho idivayisi yakho ezokwazi khona. Leli jubane lihlukaniswa phakathi kwabo bonke abasebenzisi abaxhunywe esiteshini esisodwa esisisekelo, okwenza lezi zindleko zibe yiqiniso nakakhulu kumsebenzisi ngamunye:
- Landa: 100 Mb / s (12.5 MB / s)
- Layisha: 50 Mb / s (6.25 MB / s)
Ngezivinini ezingu-5G, ungalanda i-movie ye-3 GB efonini yakho ngemizuzu emine, noma ulayishe ividiyo engu-1 GB ku-YouTube emaminithi angaphansi kwamathathu nje.
Uma kuqhathaniswa, isilinganiso esisheshayo sokulanda esithombeni esabikwa yi-Speedtest.net ngo-2017, kubasebenzisi base-United States, sasingaba ngu-22 Mbps - ngaphezu kwezikhathi ezine kancane kunalokho okuhlongozwa ngu-5G.
Ukuxhumeka koxhumano
Okungenani, i-5G izosekela amadivaysi ayizigidi ezingu-1 kuzo zonke amakhilomitha ayizikwele (0.386 miles). Lokhu kusho ukuthi ngaphakathi kwalesi samba semali, i-5G izokwazi ukuxhuma ama-1 million noma ngaphezulu amadivayisi ku-inthanethi ngesikhathi esifanayo.
Lolu hlobo lwentombazane lungase lubonakale lukhuni ukucabangela ukucabangela amadolobha anabantu abaningi kakhulu (njengoManila, ePhilippines, naseMumbai, eNdiya) kuphela abamba abantu abangu-70 000 kuya ku-110 000 kuwo wonke amakhilomitha ayizigidi.
Kodwa-ke, i-5G ayidingi ukusekela umuntu oyedwa noma amabili amadivaysi ngomuntu ngamunye kodwa futhi ne-smartwatch yomuntu wonke, zonke izimoto endaweni engase ixhunywe kwi-intanethi, ama-smart door knobs ezindlini eziseduze, nanoma yikuphi okunye okwamanje noma oku- idivaysi ekhishweyo okufanele ihlale kwinethiwekhi.
I-Latency
I-Latency ibhekisela esikhathini esiphelelwa yisikhathi phakathi kokuthi i-cell tower ithuma idatha futhi uma idivayisi yokuphela (njengefoni yakho) ithola idatha.
I-5G idinga ukulinganisa okungenani okungamamitha angu-4 nje kuphela okucabanga ukuthi izimo ezihle zihlangene, kepha zingahle zibe phansi njengo-1 ms for ezinye izinhlobo zokuxhumana, ukuxhumana okuthe ngqo okuthembekileko kwe-ultra and reliable-latency (URLLC).
Uma uqhathanisa, ukuxhumeka kwenethiwekhi ye-4G kungase kube ngu-50-100 ms, okuyiqiniso okungaphezu kokuphindwe kabili njengenethiwekhi ye-3G endala!
Ukuhamba
Ukuhamba kuhambelana nesivinini esiphezulu lapho umsebenzisi angakwazi ukuhamba khona futhi athola isevisi ye-5G.
I-5G spec ichaze amakilasi amane azosisekela, noma yikuphi ukusuka kumuntu omile ongahambeli komuntu esiteshini esisheshayo esinjengesitimela, esenyukela ku-500 kmh (310 mph).
Kungenzeka ukuthi izindawo ezihlukene zizodinga isiteshi esisezingeni leselula esilinganiselwe ukuze sibheke ngokusheshana okuhlukile. Isibonelo, idolobha elincane elinabasebenzisi abahamba ngezinyawo nezinyawo kuphela abangeke babe nesiteshi esisezingeni elifanayo efakwe edolobheni elikhulu elinesistimu yokuthutha yomphakathi esheshayo.
Ukusetshenziswa kwamandla
Ukusebenza kahle kwamandla kungenye ingxenye ebizwa nge-5G spec. I-interfaces izokwakhiwa ukuze isheshe isetshenziswe ukusetshenziswa kwamandla ngokusekelwe kokulayisha kwabo kwamanje.
Uma umsakazo ungasetshenzisiwe, uzokwehla ngaphansi kwesimo samandla aphansi ngaphansi kuka-10 ms, bese ulungisa ngokusheshisa uma kudingeka amandla amaningi.
Ulwazi oluthe xaxa ku-5G
I-5G kanye nezinye izindinganiso zeselula zokubambisana zibekwe yiProjekthi Yobambiswano Yesizukulwane Sesithathu (3GPP).
Ukuze ufunde kabanzi ngezobuchwepheshe zezingqikithi ze-5G, bheka le dokhumenti ye-Microsoft Word kusuka kwi-International Telecommunication Union (ITU).
Bheka ukuthi i-4G ne-5G ihluke kanjani? ukuze ubone ukuthi kungani ahluke nokuthi lokho kusho ukuthini kuwe namadivayisi wakho.
