Tekinoloje ya antenna ndi "malire apamwamba" a chitukuko cha dongosolo

Masiku ano, Mphunzitsi wolemekezeka Chen wochokera ku Tianya Lunxian adati, "Tekinoloje ya antenna ndiye malire apamwamba pakukula kwadongosolo.Chifukwa ndikhoza kuonedwa ngati munthu wa tinyanga, sindikanachitira mwina koma kuganizira momwe ndingamvetsetse chiganizochi komanso momwe kumvetsetsa kungakhudzire ntchito yanga yamtsogolo.

Ngati ukadaulo wa mlongoti umawonedwa ngati malire apamwamba a chitukuko cha dongosolo, kumvetsetsa kwanga koyamba ndikuti tinyanga ndi gawo lofunikira kwambiri pamakina olumikizirana opanda zingwe.Ndizida zotumizira ndi kulandira mafunde a electromagnetic, ndipo kaya ndi zida zoyankhulirana zam'manja, ma waya opanda zingwe, kapena kulumikizana ndi satellite, sangachite popanda tinyanga.

Malinga ndi momwe tinyanga zimagwiritsidwira ntchito bwino, mapangidwe ndi machitidwe a mlongoti zimakhudza mwachindunji kayendedwe ka kayendedwe kake.Ngati kapangidwe ka mlongoti ndi kolakwika (kuphatikiza malo a mlongoti, mayendedwe a mlongoti, kupindula kwa mlongoti, kufananiza kwa mlongoti, njira ya polarization ya mlongoti, ndi zina zotero), ngakhale mbali zina (monga ma amplifiers, modulators, ndi zina zotero) zikugwira ntchito bwino, sizingathe kukwaniritsa. Kuchita bwino kwambiri.

Kuchokera pamawonedwe amtundu wolandila mlongoti, kuthekera kolandila kwa mlongoti kumatsimikiziranso mtundu wa chizindikiro chakumapeto kolandira.Kusalandira bwino kwa mlongoti kungayambitse kutayika kwa chizindikiro, kusokoneza, ndi zina.

Kuchokera pamalingaliro a mphamvu ya dongosolo, mu machitidwe oyankhulana opanda zingwe, mapangidwe a antennas amakhudzanso mphamvu ya dongosolo.Mwachitsanzo, pogwiritsa ntchito magulu ovuta kwambiri a antenna, mphamvu yamakina imatha kuwonjezeka ndipo maulalo olumikizirana ofananira atha kuperekedwa.

Kuchokera pakuwona kagwiritsidwe ntchito ka malo, chitukuko chaukadaulo wa mlongoti, monga beamforming ndi MIMO (MultipleInput Multiple Output), imatha kugwiritsa ntchito bwino zinthu zakuthambo ndikuwongolera kagwiritsidwe ntchito ka ma sipekitiramu.

Kupyolera mu malingaliro omwe ali pamwambawa, chitukuko ndi kukhathamiritsa kwaukadaulo wa tinyanga takhudza kwambiri magwiridwe antchito ndi chitukuko cha machitidwe olumikizirana opanda zingwe.Zinganenedwe kuti ndi "malire apamwamba" a chitukuko cha dongosolo, zomwe zimandiwonetsa kupitiriza kwa makampani a antenna ndikufunika kupitirizabe kupita patsogolo.Koma izi sizingatanthauze kuti malinga ngati luso la antenna likuwongoleredwa, machitidwe a machitidwe amatha kusintha kwambiri, monga momwe machitidwe amagwirira ntchito amakhudzidwanso ndi zinthu zina zambiri (monga momwe ma channel, hardware, teknoloji yopangira ma signal, etc.), ndi izi. zinthu zimafunikanso kupangidwa mosalekeza kuti dongosololi likhale labwino komanso lodalirika.

Yembekezerani kutukuka ndi kupita patsogolo kwaukadaulo wa mlongoti ndi zinthu zina, monga ukadaulo wanzeru wa mlongoti, ukadaulo wophatikizika wa mlongoti, ukadaulo wa mlongoti wa photonic, ukadaulo wosinthika wa mlongoti, ukadaulo wa mlongoti wa mlongoti/MIMO/millimeter wave, ukadaulo wa mlongoti wa mlongoti, ndi zina zotero, kulimbikitsa mosalekeza. kukulitsa ukadaulo wa antenna ndikupanga opanda zingwe kukhala zaulere!
