ʻO 4G ka hā o ka ʻenehana kelepona paʻalima no ka ʻike pūnaewele paʻa. ʻOiai hoʻohana ʻia ia ma nā wahi he nui, ʻoi aku ka laha o ka hoʻohana ʻana o 4G ma nā kelepona. Ke hana nei kekahi mau hui e like me Qualcomm, Samsung, MediaTek a me Hisilicon i nā modem LTE no nā polokalamu kelepona. Ua hoʻomohala ʻia ʻo VoLTE me ka hoʻohana ʻana i ka ʻenehana LTE. Kākoʻo i nā kelepona leo HD a hoʻomaikaʻi i ka maikaʻi o ke kani i hoʻohālikelike ʻia me nā kelepona 2G/3G. ʻOiai ʻo 4 Mbps ka wikiwiki hoʻoiho kiʻekiʻe loa, ʻokoʻa ia ma nā ʻano LTE i hoʻohana ʻia i kēia hāmeʻa (CAT).
He aha ka CAT ma LTE
Ke nānā ʻoe i nā hiʻohiʻona ʻenehana o nā polokalamu me ke kākoʻo 4G, ʻike ʻia nā ʻāpana LTE. Aia he 20 mau ʻano LTE like ʻole, akā ʻo 7 o lākou ka mea maʻamau. Piʻi ka wikiwiki ke hele ʻoe i nā helu kiʻekiʻe. Papa me kekahi mau ʻano LTE a me nā wikiwiki:
| Nā Māhele LTE | Kiekie Download Speed | ʻO ka wikiwiki hoʻouka kiʻekiʻe |
|---|---|---|
| CAT 3 | 100 Mbps/Kekona | 51 Mbps/Kekona |
| CAT 4 | 150 Mbps/Kekona | 51 Mbps/Kekona |
| CAT 6 | 300 Mbps/Kekona | 51 Mbps/Kekona |
| CAT 9 | 450 Mbps/Kekona | 51 Mbps/Kekona |
| CAT 10 | 450 Mbps/Kekona | 102 Mbps/Kekona |
| CAT 12 | 600 Mbps/Kekona | 102 Mbps/Kekona |
| CAT 15 | 3.9 Gbps/Kekona | 1.5 Gbps/Kekona |
Hoʻokaʻawale ʻia nā modem ma nā kelepona, e like me nā mea hana, i nā ʻāpana like ʻole, e pili ana i ko lākou pae o ka hoʻomohala ʻana. Hiki iā mākou ke noʻonoʻo e like me ka ʻokoʻa hana ma waena o ke kaʻina hana Qualcomm Snapdragon 425 a me ke kaʻina hana Qualcomm Snapdragon 860. Loaʻa i kēlā me kēia SoC nā modem ʻokoʻa. Loaʻa iā Snapdragon 860 ka modem Qualcomm X55 aʻo ka Snapdragon 8 Gen 1 loaʻa iā Qualcomm X65 modem. Eia kekahi, he hui like ʻole kēlā me kēia mea hana. ʻO ka Combo ka nui o nā antenna i pili i ke kahua kahua. E like me kāu e ʻike ai ma ka papa ma luna, ʻokoʻa ka wikiwiki o 4G ma muli o ka māhele LTE. Inā kākoʻo kāu mea lawe i nā wikiwiki kiʻekiʻe, hiki iā ʻoe ke ʻike i nā wikiwiki i hoʻohiki ʻia ma ka māhele LTE kiʻekiʻe loa. ʻOiaʻiʻo, manaʻo ʻia kēia mau wikiwiki e hoʻonui hou aku me 5G.
