Chifukwa chiyani zosefera za RF zikukhala zofunika kwambiri?
Kukula kofulumira kwa ma data opanda zingwe am'manja ndi maukonde a 4G LTE kwapangitsa kuti pakhale kufunikira kwa magulu atsopano komanso kuphatikizika kwa zonyamulira kuphatikiza magulu kuti agwirizane ndi magalimoto opanda zingwe. Maukonde a 3G amagwiritsa ntchito magulu asanu okha, ndipo maukonde a LTE tsopano amagwiritsa ntchito magulu oposa 40, ndipo pakubwera kwa 5G, chiwerengero cha magulu chidzawonjezeka kwambiri.
Zipangizo zolumikizidwa zimatumiza siginecha m'magulu angapo: ma cellular, Wi-Fi, Bluetooth, ndi GPS, ndikupewa kusokonezedwa. Titha kuganiza nthawi yomweyo za mafoni a m'manja, zipsepse za shaki zoyikidwa pamwamba pa magalimoto, masiteshoni am'manja, ma radar ndi njira zolumikizirana, ndi mafakitale, sayansi, kapena ntchito zamankhwala zolumikizidwa ndi intaneti ya Zinthu (IoT). Panthawiyi, fyuluta imafunika kuti ituluke.
Foni yamakono yopanda fyuluta ndi njerwa
Monga tinyanga, zosefera zikukhala gawo lofunikira kwambiri la osakaniza maukonde. Chipangizocho chimalandira maulendo osiyanasiyana, ndipo fyuluta imalola kuti maulendo omwe amafunidwa adutse pamene akupondereza mafupipafupi osafunika. Mwa kuyankhula kwina, fyuluta ili ngati Gandalf mu John Ronald Ryall Tolkien "The Lord of the Rings": "Simudzadutsa!" "Zida zamasiku ano zimakhala ndi zosefera 30 mpaka 40 kuti zisasokonezedwe. Izi zitha kukhala zovuta chifukwa m'badwo wotsatira wa mafoni apamwamba umafunika zosefera zambiri.
Zosefera zopanga zovuta
Zosefera ndi chida chofunikira kwa akatswiri opanga ma RF, koma amakumananso ndi zovuta zambiri. Poyamba, ntchito ya fyuluta imasiyanasiyana ndi kutentha. Zosefera pazida zosiyanasiyana masiku ano zimatha kupirira kutentha kwapakati pa 60 degrees Celsius (140 degrees Fahrenheit) kapena kupitilira apo, pomwe zosefera zamkati zimatha kupirira kutentha kwapakati pa 25 degrees Celsius (77 degrees Fahrenheit) komanso kutentha kwambiri kwa zipsepse za shaki kapena zosefera zomwe zimayikidwa mkati. denga. Kutentha kwa fyuluta kumakwera, kumakhala kovuta kwambiri kusefa pafupipafupi, ndipo m'pamenenso chizindikirocho "chimagwedezeka" kupita ku gulu loyandikana nalo.
Kuwongolera kutentha ndikofunikira kwambiri chifukwa magulu ambiri omwe angoperekedwa kumene ali pafupi kwambiri ndi magulu omwe alipo. Panthawi imodzimodziyo, carrier aggregation (CA) ikukula mofulumira, ndi opereka chithandizo cha ma cellular akuphatikiza mpaka njira zisanu zonyamulira kuti atsimikizire momwe ma network akugwirira ntchito, kumene kusefa molondola ndikofunikira.
Pofuna kuthana ndi vuto la kutentha, makampani a RF akupanga matekinoloje otsika komanso osasunthika. Zosefera za Surface Sonic (SAW) ndi Body Sound Wave (BAW) zimasunga bata kwambiri kutentha kukamasintha, kukwaniritsa zofunikira pazida zomwe zikubwera.
Monga tafotokozera pamwambapa, m'badwo wotsatira wa mafoni apamwamba amafunikiranso kukhala ndi zosefera zambiri. Monga zigawo zina zonse za rf, pali malo ochepa kwambiri a zosefera. Mainjiniya amayenera kuphatikizira zosefera zingapo m'malo ang'onoang'ono kuti azigwira ntchito kwambiri.
Ma Duplexers, triplexers, cuadruplexers ndi hexaplexers onse pamodzi amatchedwa multiplexers. Ma Multiplexers amaphatikiza zosefera zingapo pachipangizo chimodzi kuti athandize opanga kusunga malo, kusavuta kupanga, kukwaniritsa zofunika pakuchita, komanso kupewa kusokonezedwa.
M'mawonekedwe amakono a mafoni, chiwerengero cha magulu ofunikira pa chipangizo ndi chodabwitsa, ndipo pobwera nthawi ya 5G, izi zikungowonjezereka. Ngakhale kuthandizira magulu onse kungayambitse zovuta zosokoneza, vutoli likhoza kuthetsedwa ndi fyuluta. Popanda zosefera, maukonde sagwira ntchito.
Chonde onani zosefera zathu:https://www.cdjx-mw.com/filter/
Tikukhulupirira kuti mutha kupeza zomwe mukuyang'ana, ngati sichoncho, timaperekanso makonda ndi zojambula zanu.
