4G chizvarwa chechina chebroadband mobile tekinoroji yekuwana nharembozha yeInternet. Kunyangwe ichishandiswa munzvimbo dzakawanda, kushandiswa kwe4G pamafoni kwakapararira. Mamwe makambani akadai seQualcomm, Samsung, MediaTek uye Hisilicon anogadzira LTE modemu dzenharembozha. VoLTE yakagadzirwa uchishandisa tekinoroji yeLTE. Inotsigira HD kufona kwezwi uye inovandudza ruzha rwemhando kana ichienzaniswa ne2G/3G mafoni. Kunyangwe iyo yakanyanya 4G yekumhanyisa kumhanya ichitsanangurwa se300 Mbps, inosiyana zvichienderana nemhando dzeLTE dzinoshandiswa muchina ichi (CAT).
Chii chinonzi CAT muLTE
Paunotarisa zvinhu zvehardware zvemidziyo ine 4G rutsigiro, LTE mapoka anooneka. Kune makumi maviri emhando dzeLTE dzakasiyana, asi manomwe acho anonyanya kushandiswa. Kumhanya kunowedzerawo kana uchienda kunhamba dzepamusoro. Tafura ine mamwe maLTE zvikamu uye kumhanya:
LTE Categories | Maximum Download Speed | Maximum Upload Speed |
---|---|---|
CAT3 | 100 Mbps/Sekondi | 51 Mbps/Sekondi |
CAT4 | 150 Mbps/Sekondi | 51 Mbps/Sekondi |
CAT6 | 300 Mbps/Sekondi | 51 Mbps/Sekondi |
CAT9 | 450 Mbps/Sekondi | 51 Mbps/Sekondi |
CAT10 | 450 Mbps/Sekondi | 102 Mbps/Sekondi |
CAT12 | 600 Mbps/Sekondi | 102 Mbps/Sekondi |
CAT15 | 3.9 Gbps/Masekonzi | 1.5 Gbps/Masekonzi |
Mamodhimu mumaserura, sema processor, akakamurwa muzvikamu zvakasiyana, zvichienderana nehuwandu hwavo hwebudiriro. Tinogona kufunga nezvayo semusiyano wekuita pakati peQualcomm Snapdragon 425 processor uye Qualcomm Snapdragon 860 processor. Yese SoC ine modem dzakasiyana. Snapdragon 860 ine Qualcomm X55 modem nepo Snapdragon 8 Gen 1 ine Qualcomm X65 modem. Zvakare, mudziyo wese une macombos akasiyana. Combo zvinoreva kuti mangani antennas akabatana kune base station. Sezvauri kuona mutafura iri pamusoro, kumhanya kwe4G kunosiyana zvichienderana nechikamu cheLTE. Kana mutakuri wako achitsigira kumhanya kwakanyanya, unogona kuona kumhanya kwakavimbiswa muchikamu chepamusoro cheLTE. Ehe, kumhanya uku kunotarisirwa kuwedzera zvakanyanya ne5G.
