No ke aha e lilo ai nā kānana RF i mea nui？
ʻO ka ulu wikiwiki ʻana o ka ʻikepili kelepona paʻalima a me nā pūnaewele 4G LTE ua alakaʻi i ka ulu nui o ka noi no nā pūʻulu hou a no ka hoʻohui ʻana i nā mea lawe e hoʻohui i nā kaula e hoʻokipa i nā kaʻa uila. Ke hoʻohana nei ka pūnaewele 3G ma kahi o ʻelima mau pūʻulu wale nō, a ke hoʻohana nei nā pūnaewele LTE i kēia manawa ma mua o 40 mau pūʻali, a me ka hiki ʻana mai o 5G, e piʻi hou aʻe ka nui o nā hui.
Hoʻouna nā mea i hoʻopili ʻia i nā hōʻailona ma nā ʻāpana he nui: kelepona, Wi-Fi, Bluetooth, a me GPS, ʻoiai e pale ana i ka hoʻopilikia ʻana. Hiki iā mākou ke noʻonoʻo koke i nā smartphones, nā manu manō i kau ʻia ma luna o nā kaʻa, nā kahua kahua kelepona, radar a me nā ʻōnaehana kamaʻilio, a me nā noi ʻoihana, ʻepekema, a i ʻole nā mea lapaʻau e pili ana i ka Internet of Things (IoT). I kēia manawa, pono ke kānana e puka i waho.
ʻO ke kelepona me ka kānana ʻole he pōhaku lepo
E like me nā antenna, ke lilo nei nā kānana i mea nui o nā hui hui pūnaewele. Loaʻa i ka hāmeʻa nā alapine like ʻole, a hiki i ka kānana ke hele i ka alapine i makemake ʻia e hele ma ke kāohi ʻana i ka alapine makemake ʻole. ʻO ia hoʻi, ua like ka kānana iā Gandalf ma kā John Ronald Ryall Tolkien "The Lord of the Rings": "ʻAʻole ʻoe e hala!" "Hoʻolako pinepine ʻia nā mea hana o kēia lā me 30 a 40 mau kānana e pale aku i ka hoʻopili ʻana.
Kānā i nā pilikia hoʻolālā
He mea koʻikoʻi nā kānana no nā ʻenekini hoʻolālā RF, akā ke alo nei lākou i nā pilikia he nui. No ka hoʻomaka, ʻokoʻa ka hana o ka kānana me ka mahana. Hiki i nā kānana i nā mea like ʻole i kēia lā ke kū i ka wela awelika o 60 degere Celsius (140 degere Fahrenheit) a ʻoi aku paha, ʻoiai ʻo nā kānana i loko e hiki ke kū i ka awelika wela o 25 degere Celsius (77 degere Fahrenheit) a ʻoi aku ka kiʻekiʻe o nā mahana no nā ʻili manō a i ʻole nā kānana i hoʻokomo ʻia i loko. ka hale. ʻO ke kiʻekiʻe o ka mahana o ka kānana, ʻoi aku ka paʻakikī o ka kānana ʻana i kahi alapine, a ʻoi aku ka nui o ka "holo" o ka hōʻailona i ka hui pili.
He mea koʻikoʻi ka mālama ʻana i ka neʻe ʻana o ka mahana no ka mea ua kokoke loa ka nui o nā pūʻulu i hoʻokaʻawale hou ʻia i nā pūʻulu e kū nei. I ka manawa like, ke ulu wikiwiki nei ka hoʻohui ʻana o ka mea lawe (CA), me nā mea lawelawe kelepona e hui pū ana i ʻelima mau ala lawe e hōʻoia i ka hana o ka pūnaewele, kahi e pono ai ke kānana pololei.
No ka hoʻoponopono ʻana i nā pilikia wela, ke kūkulu nei ka ʻoihana RF i nā ʻenehana kānana haʻahaʻa haʻahaʻa a me ka drift-free. Mālama nā kānana Surface Sonic (SAW) a me Body Sound Wave (BAW) i kahi kūlana kiʻekiʻe o ke kūpaʻa i ka wā e loli ai ka mahana, e hālāwai ana i nā koi koi o nā mea e puka mai ana.
E like me ka mea i ʻōlelo ʻia ma luna nei, pono e hoʻolako ʻia ka hanauna hou o nā kelepona kiʻekiʻe me nā kānana hou aʻe. E like me nā mea ʻē aʻe o rf, he wahi liʻiliʻi loa no nā kānana. Pono nā ʻenekinia e hoʻohui i nā kānana he nui i nā wahi liʻiliʻi no ka hana ʻoi aku ka maikaʻi.
ʻO nā duplexers, triplexers, cuadruplexers a me hexaplexers i hui pū ʻia he multiplexers. Hoʻohui nā Multiplexers i nā kānana he nui i hoʻokahi mea e kōkua ai i nā mea hoʻolālā e mālama i ka lewa, e hoʻomaʻamaʻa i ka hoʻolālā, e hoʻokō i nā koi o ka hana, a pale i ka hoʻopilikia.
I ke kaiapuni kelepona o kēia lā, ʻoi aku ka nui o nā pūʻali e pono ai no kahi hāmeʻa, a me ka hiki ʻana mai o ka manawa 5G, e piʻi wale ana kēia ʻano. ʻOiai ʻo ke kākoʻo ʻana i nā hui āpau hiki ke hoʻopilikia i nā pilikia, hiki ke hoʻoponopono ʻia ka pilikia me kahi kānana. Me ka ʻole o nā kānana, ʻaʻole hana wale ka pūnaewele.
E ʻoluʻolu e nānā i kā mākou kānana:https://www.cdjx-mw.com/filter/
Manaʻolana e loaʻa iā ʻoe ka mea āu e ʻimi nei, inā ʻaʻole, hāʻawi pū mākou i ka hana maʻamau me kāu kiʻi.
Ka manawa hoʻouna: Nov-26-2021
