4G ke moloko oa bone oa theknoloji ea mobile ea Broadband bakeng sa phihlello ea Marang-rang. Leha e sebelisoa libakeng tse ngata, ts'ebeliso ea 4G mehala e atile haholo. Likhamphani tse ling tse kang Qualcomm, Samsung, MediaTek le Hisilicon li etsa li-modem tsa LTE bakeng sa lisebelisoa tsa cellular. VoLTE e entsoe ka theknoloji ea LTE. E tšehetsa mehala ea lentsoe ea HD mme e ntlafatsa boleng ba molumo ha e bapisoa le mehala ea 2G/3G. Le hoja lebelo le phahameng la ho jarolla 4G le hlalositsoe e le 300 Mbps, le fapana ho latela mekhahlelo ea LTE e sebelisoang sesebelisoa sena (CAT).
CAT ke eng ho LTE
Ha u sheba likarolo tsa hardware tsa lisebelisoa tse nang le tšehetso ea 4G, lihlopha tsa LTE lia hlaha. Ho na le lihlopha tse 20 tse fapaneng tsa LTE, empa tse 7 tsa tsona li sebelisoa haholo. Lebelo le boetse le eketseha ha u ea linomoro tse phahameng. Tafole e nang le mekhahlelo e meng ea LTE le lebelo:
| Likarolo tsa LTE | Lebelo le phahameng la ho jarolla | Lebelo le phahameng la ho kenya |
|---|---|---|
| EA-3-CAT | 100 Mbps/Metsotsoana | 51 Mbps/Metsotsoana |
| EA-4-CAT | 150 Mbps/Metsotsoana | 51 Mbps/Metsotsoana |
| EA-6-CAT | 300 Mbps/Metsotsoana | 51 Mbps/Metsotsoana |
| EA-9-CAT | 450 Mbps/Metsotsoana | 51 Mbps/Metsotsoana |
| EA-10-CAT | 450 Mbps/Metsotsoana | 102 Mbps/Metsotsoana |
| EA-12-CAT | 600 Mbps/Metsotsoana | 102 Mbps/Metsotsoana |
| EA-15-CAT | 3.9 Gbps/Metsotsoana | 1.5 Gbps/Metsotsoana |
Li-modem ka liselefouno, joalo ka li-processor, li arotsoe ka mekhahlelo e fapaneng, ho latela boemo ba bona ba nts'etsopele. Re ka nahana ka eona joalo ka phapang ea ts'ebetso lipakeng tsa processor ea Qualcomm Snapdragon 425 le processor ea Qualcomm Snapdragon 860. SoC e 'ngoe le e' ngoe e na le li-modem tse fapaneng. Snapdragon 860 e na le modem ea Qualcomm X55 ha Snapdragon 8 Gen 1 e na le modem ea Qualcomm X65. Hape, sesebelisoa se seng le se seng se na le li-combos tse fapaneng. Combo e bolela hore na ke li-antenna tse kae tse hoketsoeng seteisheneng. Joalo ka ha u bona tafoleng e kaholimo, lebelo la 4G le fapana ho latela sehlopha sa LTE. Haeba sesebelisoa sa hau se ts'ehetsa lebelo le holimo, u ka bona lebelo le ts'episitsoeng sehlopheng se phahameng ka ho fetisisa sa LTE. Ehlile, lebelo lena le lebelletsoe ho eketseha le ho feta ka 5G.
