Mawayilesi pafupipafupi(RF) teknoloji ndi teknoloji yolankhulirana yopanda zingwe, yomwe imagwiritsidwa ntchito makamaka pawailesi, mauthenga, radar, remote control, wireless sensor network ndi zina. Mfundo yaukadaulo waukadaulo wamawayilesi opanda zingwe idakhazikitsidwa paukadaulo wofalitsa ndikusintha komanso kutulutsa mafunde amagetsi. Pansipa ndikudziwitsani zaukadaulo waukadaulo wamawayilesi opanda zingwe.
Mfundo zaukadaulo
Ukadaulo wa mawayilesi opanda zingwe ndiukadaulo womwe umagwiritsa ntchito mafunde a wailesi polumikizana. Mafunde a wailesi kwenikweni ndi mtundu wa mafunde a electromagnetic okhala ndi ma frequency ndi milingo yeniyeni. Mukulankhulana kwa mawayilesi opanda zingwe, malekezero otumizira amasintha ma siginecha azidziwitso kukhala mafunde amagetsi amagetsi kudzera pa mafunde a wailesi ndikuwatumiza. Mapeto omwe amalandila amalandira ma siginecha a electromagnetic wave kenako amawasintha kukhala zizidziwitso kuti akwaniritse kutumiza ndi kulumikizana kwa data.
Kulandila ndi kutumizira mawayilesi pafupipafupi
Mfundo zaukadaulo wamawayilesi opanda zingwe zimaphatikizanso izi:
Kusinthasintha pafupipafupi: Pakulumikizana kwa mawayilesi opanda zingwe, ma siginecha azidziwitso amasinthidwa kukhala ma electromagnetic wave ma frequency apadera kutengera ukadaulo wosinthira. Njira zophatikizira zodziwika bwino ndi monga amplitude modulation blending (AM), frequency modulation blending (FM), ndi phase modulation blending (PM).
Mlongoti: Mlongotindi gawo lofunikira kwambiri pamawayilesi olumikizana ndi mawayilesi opanda zingwe. Amagwiritsidwa ntchito kutumiza ndi kulandira mafunde a wailesi. Mapangidwe ndi kuyika kwa tinyanga kumakhudza mtunda wotumizira ndi khalidwe la mauthenga opanda zingwe.
Mlongoti wa nyanga ya Broadband (1-18GHz)
Mlongoti Wokhazikika wa Horn Horn (4.90-7.05GHz)
Mlongoti wa Nyanga Yapawiri Yokhazikika (2-18GHz)
RF MisoMalangizo azinthu za mlongoti
Kulemba makhoti ndi kumasulira: M'mawu ochezera a pawailesi opanda zingwe, ukadaulo wa ma codec ndi decoding umagwiritsidwa ntchito kukonza bata ndi kusokoneza kulumikizana ndikuwonetsetsa kulondola kwa kulumikizana kwa data.
Kuwongolera mphamvu: Kuyankhulana kwa mawayilesi opanda zingwe kumafunika kusintha mphamvu yokankhira kuti iwonetsetse kuti chizindikirocho chikhoza kufalikira mumtundu wina ndikuletsa kuti chisakhudze china.
Frequency band management: Kuyankhulana kwa mawayilesi opanda zingwe kuyenera kuyang'anira bwino zida za sipekitiramu kuti zipewe kuonongeka kwa zida zama frequency band ndikuwonetsetsa kukhazikika ndi kudalirika kwa kulumikizana.
Zochitika zantchito
Ukadaulo wa mawayilesi opanda zingwe amagwiritsidwa ntchito kwambiri masiku ano, kupereka zabwino zambiri komanso zatsopano pamiyoyo ya anthu ndi ntchito. Nawa madera omwe amagwiritsidwa ntchito ndi ma RF opanda zingwe:
Kulumikizana kwa mafoni: Maziko a mauthenga a m'manja kwenikweni ndi luso lapamwamba la wailesi, kuphatikizapo mafoni a m'manja, mawayilesi opanda zingwe, mauthenga a satana, ndi zina zotero. Zida zamakono zotsatizanazi zimalola anthu kuyimba mawu, kutumiza mauthenga, ndi kupeza intaneti nthawi iliyonse komanso kulikonse.
Nyumba yanzeru: M'makina anzeru apanyumba, monga maloko a zitseko zanzeru, zowongolera zowunikira mwanzeru, zida zapanyumba zanzeru, ndi zina zambiri, kuwongolera kwakutali komanso kuyang'anira mwanzeru zitha kupezedwa kudzera muukadaulo wopanda zingwe.
Intaneti ya Zinthu: Ukadaulo wamawayilesi opanda zingwe ndi gawo lofunikira pa intaneti ya Zinthu. Imazindikira kulumikizana pakati pa zida kudzera pamanetiweki opanda zingwe ndipo imazindikira kuwunika mwanzeru, kusonkhanitsa deta komanso kuwongolera kutali.
Network sensor yopanda zingwe: M'magulu a sensa opanda zingwe, amagwiritsidwa ntchito makamaka poyang'anira chilengedwe, thanzi lachipatala, kayendetsedwe ka mafakitale ndi zina kuti akwaniritse kusonkhanitsa deta ndi kuyang'anira nthawi yeniyeni.
Zida zowongolera opanda zingwe: Ukadaulo wamawayilesi opanda zingwe amagwiritsidwa ntchito kwambiri pamagawo owongolera monga zowongolera zakutali za TV, owongolera magalimoto, ndi owongolera amitundu kuti amalize ntchito zakutali.
Pulogalamu ya radar: Wailesiukadaulo wa pafupipafupi umagwira ntchito yofunika kwambiri pamakina a radar ndipo umagwiritsidwa ntchito pozindikira chandamale, kutsatira ndikuyenda. Amagwiritsidwa ntchito kwambiri muzamlengalenga, meteorology ndi magawo ena.
Kugwiritsa ntchito ukadaulo wa ma radio frequency ndi otakata kwambiri, okhudza magawo ambiri, monga kulumikizana ndi mafoni, ma satellite olankhulana, makina a radar, zowongolera zakutali, ma network a sensor opanda zingwe, ndi zina. gawo lofunikira m'magawo osiyanasiyana, kubweretsa kumasuka komanso luso lambiri pamiyoyo ya anthu ndi ntchito.
