4G ndi m'badwo wachinayi waukadaulo wam'manja wa Broadband pa intaneti. Ngakhale imagwiritsidwa ntchito m'malo ambiri, kugwiritsa ntchito 4G pamafoni ndikofala kwambiri. Makampani ena monga Qualcomm, Samsung, MediaTek ndi Hisilicon amapanga ma modemu a LTE pazida zam'manja. VoLTE idapangidwa pogwiritsa ntchito ukadaulo wa LTE. Imathandizira kuyimba kwamawu a HD ndikukweza mawu abwino poyerekeza ndi mafoni a 2G/3G. Ngakhale kuti liwiro lapamwamba la 4G lotsitsa limatchulidwa kuti 300 Mbps, limasiyana malinga ndi magulu a LTE omwe amagwiritsidwa ntchito pa chipangizochi (CAT).
CAT mu LTE ndi chiyani
Mukayang'ana zida za zida zokhala ndi chithandizo cha 4G, magulu a LTE amawonekera. Pali magulu 20 osiyanasiyana a LTE, koma 7 mwa iwo amagwiritsidwa ntchito kwambiri. Liwiro limakulanso mukapita ku manambala apamwamba. Tebulo lomwe lili ndi magawo ena a LTE ndi liwiro:
Magawo a LTE | Kuthamanga Kwambiri Kwambiri | Kuthamanga Kwambiri Kwambiri |
---|---|---|
Amphaka 3 | 100 Mbps/Mphindikati | 51 Mbps/Mphindikati |
Amphaka 4 | 150 Mbps/Mphindikati | 51 Mbps/Mphindikati |
Amphaka 6 | 300 Mbps/Mphindikati | 51 Mbps/Mphindikati |
Amphaka 9 | 450 Mbps/Mphindikati | 51 Mbps/Mphindikati |
Amphaka 10 | 450 Mbps/Mphindikati | 102 Mbps/Mphindikati |
Amphaka 12 | 600 Mbps/Mphindikati | 102 Mbps/Mphindikati |
Amphaka 15 | 3.9 Gbps/Mphindikati | 1.5 Gbps/Mphindikati |
Ma modemu m'mafoni am'manja, monga ma processor, amagawidwa m'magulu osiyanasiyana, kutengera kukula kwawo. Titha kuziganizira ngati kusiyana kwa magwiridwe antchito pakati pa purosesa ya Qualcomm Snapdragon 425 ndi purosesa ya Qualcomm Snapdragon 860. SoC iliyonse ili ndi ma modemu osiyanasiyana. Snapdragon 860 ili ndi Qualcomm X55 modemu pomwe Snapdragon 8 Gen 1 ili ndi Qualcomm X65 modemu. Komanso, chipangizo chilichonse chimakhala ndi ma combo osiyanasiyana. Combo amatanthauza tinyanga zingati zolumikizidwa ku base station. Monga mukuwonera patebulo pamwambapa, kuthamanga kwa 4G kumasiyana malinga ndi gulu la LTE. Ngati chonyamulira chanu chimathandizira kuthamanga kwambiri, mutha kuwona kuthamanga kolonjezedwa m'gulu lapamwamba kwambiri la LTE. Zachidziwikire, kuthamanga uku kukuyembekezeka kuwonjezeka kwambiri ndi 5G.
