I-Long Term Evolution - Inethiwekhi ye-4G engenazintambo esheshayo
I-LTE imele i-Long Term Evolution futhi iyinombolo ye- wireless ye-wireband engu- 4G . Kuyinto inethiwekhi engenazintambo ezingenazintambo ze-Smartphones namadivayisi eselula. Ishintshile amanethiwekhi wangaphambili we-4G njengo- WiMax futhi isenqubo yokufaka i- 3G kumadivayisi amaningi.
I-LTE inikeza umkhawulokudonsa ophakeme, okusho ukuvinjelwa okukhulu kokuxhumeka, nobuchwepheshe obungcono bokusebenzisa izingcingo zezwi (i- VoIP ) nokusakazwa kwe- multimedia. Kungcono ukufaneleka kwezicelo ezinzima kakhulu futhi ezilamandla emiphakathini kumadivayisi eselula.
Ukuthuthukiswa okunikezwa yi-LTE
I-LTE inikeza umsebenzi ongcono on-line namadivaysi eselula ngenxa yezici ezilandelayo:
- Ukukhula okusheshayo nokulayishwa ngesivinini.
- I- latency yokudluliswa kwedatha ephansi .
- Ukwesekwa okuthuthukisiwe kwamadivayisi eselula.
- Ingabe i-scalable eyengeziwe, okungaba khona amadivaysi amaningi axhumene nendawo yokufinyelela ngesikhathi.
- Kuhlanjululwe izingcingo zezwi, nge- codec ezithuthukisiwe nokushintshwa ngcono. Lokhu buchwepheshe bubizwa nge-Voice over LTE (VoLTE).
Okudingayo LTE
Ukuze sigcine leli khasi lilula, ngeke sikhulume ngezidingo zenethiwekhi eziyinkimbinkimbi ezingeni labahlinzeki bezinsizakalo nama-opharetha wenethiwekhi. Ake siwuthathe ohlangothini lomsebenzisi, ohlangothini lwakho.
Okokuqala, udinga kuphela idivayisi yeselula esekela i-LTE. Ungathola lokhu kuzincazelo zedivayisi. Ngokuvamile, ukuqamba igama kufika njengo-4G-LTE. Uma ufuna ukuyisebenzisa kakhulu kodwa ube nedivayisi engasekeli i-LTE, unamathela ngaphandle kokuthi ushintshe idivayisi yakho. Futhi, akuwona wonke amadivayisi abonisa i-LTE kuma-specs awo athembekile.
Lesi sichazamagama sinesihluthulelo sibe yithuluzi lokumaketha futhi kuvame ukudukisa. Abanye abakhiqizi bahluleka ukuphila ngokuvumelana nokulindelwe lapho behambisa i-LTE hardware. Ngaphambi kokuthenga i-smartphone yakho noma amanye amadivaysi, funda izibuyekezo, hlola ama-verdicts abahloli, futhi uqaphele ukusebenza kwangempela kwe-LTE yedivayisi.
Khona-ke, empeleni, udinga umhlinzeki wensizakalo onokufinyelela okuqinile endaweni ohamba kuyo. Akusetshenziselwa ukutshala izimali kumadivayisi we-LTE uma indawo yakho ingahlanganiswa kahle.
Kudingeka ucabangele izindleko. Ukhokha i-LTE njengoba ukhokha noma yiluphi uhlelo lwemininingwane ye-3G. Eqinisweni, kuvame ukuza necebo elifanayo ledatha, njengesibuyekezo. Uma i-LTE ingatholakali endaweni, uxhumano luzenzekela ngokuzenzakalelayo ku-3G.
Umlando we-LTE
I-3G yayiyi-revolution ngempela phezu kwe-2G yeselula, kodwa isingenayo i-punch yejubane. I-ITU-R, umzimba olawula ukuxhuma nokuvinjelwa, weza ngonyaka ka-2008 ngezimiso ezithuthukisiwe zezidingo ezizokwanelisa izidingo zanamuhla zezindlela zokukhulumisana nokusetshenziswa kwedatha ezithuthukisiwe, njenge-Voice over IP, amavidiyo asakazwayo, i- video conferencing , ukudluliswa kwedatha, ukusebenzisana kwangempela-isikhathi njll. Leli setha elisha lezincazelo lalingu-4G, okusho isizukulwane sesine. Isivinini sinye yezincazelo eziyinhloko.
Inethiwekhi ye-4G, ngokwalezi zinkcazo, inganikeza isivinini sezingu-100 Mbps ngesikhathi sokunyakaza, kufana nemoto noma isitimela, kuze kufike ku-1Gbps uma umisiwe. Lezi kwakuyizinhloso eziphezulu, futhi kusukela i-ITU-R engazange ikhulume ekusetshenzisweni kwalezi zindinganiso, kwakudingeka ilahle imithetho embalwa, ukuze ubuchwepheshe obusha bungabhekwa njenge-4G naphezu kokuwa kwezinga eliphansi ngenhla.
Imakethe yalandelwa, futhi saqala ukuthola ukuqaliswa kwe-4G. Nakuba singakabi kuze kube sekugcineni kwegigabit ngomzuzwana, amanethiwekhi we-4G akhombise ukuthuthuka okukhulu ngaphezu kwe-3G. I-WiMax yayiyi-offshoot kodwa ayizange iphile ngokuyinhloko ngenxa yokuthi yayisebenzisa ama-microwave futhi idinga umugqa wokubona ukuze ufike ngesivinini esifanele.
I-LTE yimibukiso ye-4G futhi iyona esheshayo emhlabeni wonke. Amandla ayo aphezu kwezici eziningana. Isebenzisa amagagasi omsakazo, ngokungafani ne-3G ne-WiMAX, esebenzisa ama-microwaves. Yilokho okubangela ukuthi isebenze kwi-hardware ekhona. Lokhu kubangela ukuthi amanethiwekhi e-LTE abe nokungena okungcono ezindaweni ezikude futhi abe nesilinganiso esikhulu sokuhlanganisa. I-LTE isebenzisa izintambo ezithile ze- fiber optic , ama-codec angcono okufaka ama-encoding, futhi zithuthukiswa ekudluliseni kwe-multimedia nokuxhumana kwedatha.
