I ka makahiki 2020, me ka laulima pū ʻana me Huawei ma Kina, e komo mākou i ke kūkulu ʻana i nā tausani o nā kikowaena kelepona uea ʻole ma ka huina, a ma waena o ia mau mea e hoʻolako mākou i nā mea hoʻokaʻawale mana microstrip me nā alapine (frequencies) o 0.5/6g a me 1-50g ma ke ʻano he lako kākoʻo.
E ʻoi aku ka nui o ka uhi ʻana o nā lako kikowaena kelepona uea ʻole i ka makahiki 2021, a ua manaʻo ʻia ka huina e ʻoi aku ma mua o nā ʻumi kaukani o nā hāmeʻa.
Nā kaula alapine (frequency bands) kūpono no nā kamaʻilio ukali
Manawa: 2021-10-28
Ho'ākāka ʻo ITU i nā alapine (frequency bands), i hoʻohana ʻia no nā kamaʻilio ukali.
ʻO UHF (Ultra High Frequency) a i ʻole ke kāʻei alapine (frequency) o ka nalu desimika, ʻo ka laulā alapine (frequency) he 300MHz-3GHz.
Pili kēia alapine (frequency band) i nā alapine (frequency band) IEEE UHF (300MHz-1GHz), L (1-2GHz), a me S (2-4GHz).
ʻO nā nalu lekiō o ke alapine UHF kokoke i ka laha ʻana o ka laina o ka ʻike, maʻalahi ke ālai ʻia e nā mauna a me nā hale, a pēlā aku, a he nui ka attenuation o ka hoʻoili ʻana i loko.
ʻO ka SHF (Super High Frequency) a i ʻole ke kāʻei alapine (frequency) o ka nalu kenimika, ʻo ka laulā alapine (frequency) he 3-30GHz.
Pili kēia alapine (frequency band) i nā alapine (frequency band) IEEE S (2-4GHz), C (4-8GHz), Ku (12-18GHz), K (18-27GHz) a me Ka (26.5-40GHz).
He 1cm-1dm ka lōʻihi o ka nalu o nā nalu dekimeta, a ua kokoke ko lākou mau ʻano hoʻolaha i nā nalu māmā.
ʻO ka EHF (Extremely High Frequency) a i ʻole ke kāʻei alapine (frequency) millimeter wave frequency, ʻo ka laulā alapine (frequency) he 30-300GHz.
Pili kēia alapine (frequency band) iā Ka (26.5-40GHz) a IEEE, V (40-75GHz) a me nā alapine ʻē aʻe.
Ua hoʻomaka nā ʻāina i hoʻomohala ʻia i nā hoʻolālā e hoʻohana i nā kāʻei alapine (frequency) 50/40GHz Q/V ma nā puka komo o ka lawelawe ukali paʻa kiʻekiʻe (HDFSS) i ka wā e paʻa ana nā kumuwaiwai Ka-band.
Hiki iā mākou ke hoʻopilikino i nā ʻāpana passive rf e like me kāu mau koi. Hiki iā ʻoe ke komo i ka ʻaoʻao hoʻopilikino e hāʻawi i nā kikoʻī āu e pono ai.
