Kusintha kwa Nthawi Yakale - Mtumiki Wopanda Utsi Wopanda Utsi wa 4G
LTE imayimira Long Term Evolution ndipo ili ndi 4G yamphaneti ya broadband standard. Ndilo makina osayendetsa opanda pakompyuta kwa mafoni ndi mafoni. Lalowa m'malo mwa ma Intaneti 4G monga WiMax ndipo ikukonzekera 3G pazinthu zambiri.
LTE imapereka mapepala apamwamba, kutanthauza kugwirizana kwakukulu kofulumira, komanso chithunzithunzi chopambana cha mauthenga a voIP ( VoIP ) ndi kusakanikirana ndi multimedia. Ndizoyenera kwazomwe zimakhala zovuta kwambiri komanso zogwira ntchito zokhudzana ndi zida zogwiritsira ntchito mafoni.
Zosintha zomwe LTE amapereka
LTE imapereka ntchito yabwino pa intaneti ndi mafoni apangizo chifukwa cha zotsatirazi:
- Kuwonjezeka kwakukulu ndi kukweza msanga.
- Low latency transfer transfer.
- Kupititsa patsogolo thandizo la mafoni.
- Kodi ndizowonjezereka, kotero kuti pangakhale zipangizo zochuluka zokhudzana ndi kupeza nthawi panthawiyi.
- Yoyengedwa chifukwa cha kuyitana kwa voli, ndi ma codec opititsa patsogolo komanso kusintha kwabwino. Njirayi imatchedwa Voice over LTE (VoLTE).
Zimene Mukufunikira Kwa LTE
Pofuna kuti tsamba ili likhale losavuta, sitidzakambirana za zovuta zomwe zimagwiritsidwa ntchito pamtundu wa ogwira ntchito ndi ogwira ntchito. Tiyeni titenge izo kumbali ya wosuta, mbali yanu.
Choyamba, mumangofunikira kachipangizo kamene kamathandiza LTE. Mukhoza kupeza izi muzinthu za chipangizochi. Kawirikawiri, kutchula dzina kumabwera ngati 4G-LTE. Ngati mukufuna kugwiritsa ntchito bwino koma muli ndi chipangizo chomwe sichichirikiza LTE, mumakanikira pokhapokha mutasintha chipangizo chanu. Ndiponso, si zipangizo zonse zosonyeza LTE muzinthu zawo zodalirika.
Mwalankhula izi mwatsoka wakhala chida cha malonda ndipo nthawi zambiri amasocheretsa. Opanga ena amalephera kutsatira zomwe akuyembekeza pamene akupereka LTE hardware. Musanagule foni yamakono anu kapena zipangizo zina, werengani ndemanga, fufuzani zowonongeka, ndikuyang'anitsitsa ntchito ya LTE.
Ndiye, ndithudi, mukusowa wothandizira opereka chithandizo chomwe chili ndi malo omwe mumayendera. Silikugwiritsanso ntchito ndalama zanu pa zipangizo za LTE ngati dera lanu silikuphimbidwa bwino.
Muyeneranso kulingalira mtengo. Mukulipira LTE pamene mukulipira ndondomeko iliyonse ya deta ya 3G. Ndipotu, nthawi zambiri zimabwera ndi dongosolo lomwelo la deta, monga momwe zilili. Ngati LTE sichipezeka m'deralo, kugwirizana kumasintha mpaka 3G.
Mbiri ya LTE
3G inali yotembenuza pa 2G ya ma selo, koma inalibe vuto la liwiro. Thupi la ITU-R, lomwe limayendera kugwirizana ndi kupititsa patsogolo, linabwera mu 2008 ndi zolemba zofunikira zomwe zingakwaniritse zosowa zamakono zowonjezera njira zoyankhulirana ndi mafoni, monga Voice over IP, mavidiyo akutsitsa, mavidiyo , kusamutsidwa kwa deta, mgwirizano wa nthawi yeniyeni. Izi zida zatsopano zinatchedwa 4G, zomwe zikutanthauza m'badwo wachinayi. Liwiro linali chimodzi mwazidziwitso zazikulu.
Mndandanda wa 4G, malinga ndi izi, zimapereka maulendo 100 Mbps pakuyenda, monga galimoto kapena sitimayi, mpaka 1Gbps pamene zatsala. Izi zinali zolinga zapamwamba, ndipo popeza ITU-R sananene chilichonse potsata mfundo zoterezi, zinayenera kusokoneza malamulo pang'ono, kotero kuti njira zamakono zatsopano zingaganizidwe ngati 4G ngakhale kuti zowonongeka zowonongeka.
Msikawo unatsatira, ndipo tinayamba kupeza 4G kukwaniritsa. Ngakhale kuti sitinathe kufika pa gigabit pamphindi, magulu a 4G adasintha kwambiri kuposa 3G. WiMax inali mphukira koma siidapulumutse makamaka chifukwa chakuti idagwiritsa ntchito microwaves ndipo imafunikira mzere woonekera kuti ufulumire mwamsanga.
LTE ndi teknoloji ya 4G ndipo ndi yofulumira kwambiri mpaka pano. Mphamvu zake zili ndi zifukwa zingapo. Amagwiritsa ntchito mafunde a wailesi, mosiyana ndi 3G ndi WiMAX, zomwe zimagwiritsa ntchito microwaves. Izi ndi zomwe zimayambitsa ntchito pa hardware yomwe ilipo. Izi zimapangitsanso makanema a LTE kuti alowe bwino m'madera akumidzi ndikukhala ndi nthawi yayitali. LTE amagwiritsa ntchito zingwe za fiber optic , ma codec abwino a zizindikiro za encoding, ndipo zimapangidwira kuti zitha kulankhulana ndi ma data.
