Ixesha elide lokuziphendulela - Unxibelelwano olukhawulezayo lwe-Wireless 4G Network
I-LTE imele i-Long Term Evolution kwaye iyimilinganiselo ye- wireless ye-wireless ye- 4G . Yona inethiwekhi engena-wireless ye-smartphones kunye namadivayisi eselula. Yatshintshile amanethiwekhi angaphambili angama-4G njenge- WiMax kwaye inenkqubo yokwenza indawo ye- 3G kumadivayisi amaninzi.
I-LTE inikeza umda womda wokuphakama ophezulu, onentsingiselo enkulu yokuxhumeka kokuxhumeka, kunye nekhompyutheni engcono yeefowuni zezwi ( VoIP ) kunye ne-multimedia ukusakaza . Kulungele ukulungelelanisa izicelo ezilambileyo kunye neefomidth-hungry hungry devices.
Ukuphuculwa kweLTE
I-LTE inikela ngomsebenzi ongcono kumnxeba kunye nezixhobo zeselula ngenxa yezinto ezilandelayo:
- Ukukhulisa ngokukhawuleza ukulayisha kunye nokukhuphela umda.
- I- latency yokudluliswa kwedatha.
- Inkxaso ephakamileyo yezixhobo zeselula.
- Ingaba yinto engabonakaliyo, enokuthi kubekho amacebo amaninzi axhunyiwe kwindawo yokufikelela ngexesha.
- Ucocekileyo ngeefowuni zeezwi , ngeekhowudi eziphuculweyo kunye nokutshintshwa ngcono. Le teknoloji ibizwa ngezwi kwiLTE (VoLTE).
Oko Ufunayo LTE
Ukugcina eli phepha lilula, asiyi kuthetha ngeemfuno ezixakekileyo zenethwekhi kumgangatho wabanikezeli benkonzo kunye nabaqhubi benethiwekhi. Masiwuthathe kwicala lomsebenzisi, icala lakho.
Okokuqala, ufuna kuphela idivayisi ephathekayo exhasa i-LTE. Unokukufumana oku kwiinkcukacha zecebo. Ngokuqhelekileyo, igama liza njenge-4G-LTE. Ukuba ufuna ukwenza ubuninzi balo kodwa ube necebo elingenakuxhasa i-LTE, unamathela ngaphandle kokuba utshintshe idivayisi yakho. Kwakhona, akuzona zonke izixhobo ezibonisa i-LTE kuma-specs azo athembekileyo.
Esi sichazi sele siba sisixhobo sokuthengisa kwaye sihlala silahleka. Abanye abakhiqizi bahluleka ukuphila ngokubhekiselele kulindeleke xa behambisa i-LTE hardware. Ngaphambi kokuthenga i-smartphone yakho okanye nayiphi na ifowuni, funda ukuphononongwa, khangela izitriki zeentlola, kwaye uqaphele ukusebenza okwenziweyo kweLTE.
Ngoko ke, ke, ufuna umboneleli wenkonzo onenkxaso ephezulu kwindawo ohambisa kuyo. Akusisebenzisi ukutshala imali kwii-LTE iidivaysi ukuba indawo yakho ayifakwe kakuhle.
Kufuneka kwakhona ucinge ngeendleko. Uhlawula i-LTE njengoko uhlawula nayiphi na icebo ledatha ye-3G. Enyanisweni, ngokuqhelekileyo kuza necebo elifanayo ledatha, njengesibuyekezo. Ukuba i-LTE ayifumanekanga kwindawo, uxhumano luzenzekela ngokuzenzekelayo kwi-3G.
Imbali yeLTE
I-3G yayiyi-revolution ngaphezu kwe-2G yeselula, kodwa yayingenayo ipopu yesantya. I-ITU-R, umzimba olawula ukudibanisa kunye nokukhawuleza, weza ngo-2008 kunye neetekethi yokuphuculwa kweemfuno eziza kukwanelisa iimfuno zanamhlanje zokunxibeleliswa kweendlela zokunxibelelana kunye nokusetyenziswa kwedatha yeselula, njenge-Voice over IP, iividiyo ezihambayo, i- video conferencing , ukudluliswa kwedatha, ukubambisana kwexesha langempela njl. Le setethi entsha yeenkcukacha zathiwa ngu-4G, oku kuthetha isizukulwana sesine. Isantya sinye yeenkcukacha eziphambili.
Inethiwekhi ye-4G iya kuthi, ngokwale nkcazo, inika isivinini kwi-100 Mbps ngexesha lokunyakaza, njengemoto okanye isitimela, ukuya kwi-1Gbps xa uhleli. Ezi zijoliswe kuzo, kwaye ekubeni i-ITU-R yayingenaso ukuthetha ekuphunyezweni kwaloo migangatho, kwakufuneka ilawule imigaqo encinane, njengokuba ubuchwepheshe obutsha bunokuqwalaselwa ngo-4G naphezu kokuwa kwezantsi kwezi zikhankanywe ngasentla.
Iimakethe zalandelwa, kwaye saqala ukuphunyezwa kwe-4G. Nangona singekho kwi-gigabit yesibini, amanethiwekhi e-4G agxininise ukuphucuka okukhulu ngaphezu kwe-3G. I-WiMax yayiyi-offshoot kodwa ayizange iphile ngenxa yokuba yayiyisebenzisa i-microwave kwaye yayifuna umgca wokubona kwixesha elifanelekileyo.
I-LTE yi-teknoloji ye-4G kwaye iyona ekhawulezileyo malunga nokude. Amandla ayo ahlala kwiimeko ezininzi. Isebenzisa amaza omsakazo, ngokungafani ne-3G kunye ne-WiMAX, esebenzisa ii-microwaves. Oku kubangela ukuba isebenze kwi-hardware ekhoyo. Oku kubangela ukuba amanethiwekhi e-LTE abe nokungena kakuhle kwiindawo ezikude kwaye abe nexesha elibanzi lokukhawulela. I-LTE isebenzisa inxenye yecingo ye-fiber optic , i-codec engcono yokubonakalisa i-encoding signals, kwaye iphakanyiselwe ukuhanjiswa kwe-multimedia kunye nokunxibelelana kwedatha.
