I-4G sisizukulwana sesine sobuchwepheshe be-broadband mobile ukufikelela kwi-Intanethi. Nangona isetyenziswa kwiindawo ezininzi, ukusetyenziswa kwe-4G kwiifowuni kuxhaphake kakhulu. Ezinye iinkampani ezifana neQualcomm, iSamsung, iMediaTek kunye neHisilicon zenza iimodem zeLTE zezixhobo eziphathwayo. IVoLTE yaphuhliswa kusetyenziswa ubuchwepheshe be-LTE. Ixhasa iifowuni zezwi ze-HD kunye nokuphucula umgangatho wesandi xa kuthelekiswa neefowuni ze-2G / 3G. Nangona isantya esiphezulu se-4G sokukhuphela sichazwe njenge-300 Mbps, siyahluka ngokuxhomekeke kwiindidi ze-LTE ezisetyenziswe kwesi sixhobo (CAT).
Yintoni i-CAT kwi-LTE
Xa ujonga iimpawu ze-hardware zezixhobo ezinenkxaso ye-4G, iindidi ze-LTE ziyavela. Kukho iindidi ezingama-20 ezahlukeneyo ze-LTE, kodwa ezisi-7 kuzo zisetyenziswa kakhulu. Isantya sinyuka xa usiya kumanani aphezulu. Itheyibhile enolunye uhlobo lwe-LTE kunye nesantya:
| Iindidi ze-LTE | Esona santya siphezulu sokukhuphela | Isantya esiphezulu sokulayisha |
|---|---|---|
| Ikati 3 | 100 Mbps/Imizuzwana | 51 Mbps/Imizuzwana |
| Ikati 4 | 150 Mbps/Imizuzwana | 51 Mbps/Imizuzwana |
| Ikati 6 | 300 Mbps/Imizuzwana | 51 Mbps/Imizuzwana |
| Ikati 9 | 450 Mbps/Imizuzwana | 51 Mbps/Imizuzwana |
| Ikati 10 | 450 Mbps/Imizuzwana | 102 Mbps/Imizuzwana |
| Ikati 12 | 600 Mbps/Imizuzwana | 102 Mbps/Imizuzwana |
| Ikati 15 | 3.9 Gbps/Imizuzwana | 1.5 Gbps/Imizuzwana |
Iimodemu kwiiselfowuni, njengeeprosesa, zohlulwe ngokweendidi ezahlukeneyo, kuxhomekeke kwinqanaba lophuhliso. Sinokucinga ngayo njengomahluko wokusebenza phakathi kweprosesa yeQualcomm Snapdragon 425 kunye neQualcomm Snapdragon 860 processor. Yonke i-SoC inemodem ezahlukeneyo. I-Snapdragon 860 inemodem yeQualcomm X55 ngelixa i-Snapdragon 8 Gen 1 inemodem yeQualcomm X65. Kwakhona, zonke izixhobo zineekhombo ezahlukeneyo. I-Combo ithetha ukuba zingaphi ii-eriyali eziqhagamshelwe kwisikhululo esisisiseko. Njengoko ubona kwitheyibhile engentla, izantya ze-4G ziyahluka ngokuxhomekeke kudidi lwe-LTE. Ukuba umnikezeli wakho uxhasa isantya esiphezulu, ungabona izantya ezithenjisiweyo kwelona nqanaba liphezulu le-LTE. Ewe, ezi zantya kulindeleke ukuba zonyuke ngakumbi nge-5G.
