Chizindikiro cha foni yam'manja cha amplifier board antenna chizindikiro champhamvu

Amplifier ya foni yam'manjaChizindikiro cha mlongoti wa board chifukwa champhamvu: Pankhani ya kuphimba ma siginecha, mlongoti wa mbale yayikulu ndi "mfumu" ngati kukhalapo! Kaya mumachubu, m'zipululu, kapena m'mapiri ndi malo ena otumizira ma siginecha atalitali, mutha kuwona nthawi zambiri. Chifukwa chiyani mlongoti wa mbale waukulu uli wamphamvu chonchi? Ndi zochitika ziti zomwe zingagwiritsidwe ntchito? Tiyeni tiwone pansipa.

Omnidirectional Antenna VS Directional Antenna

Mlongoti wa mbale yayikulu kwenikweni ndiwokwera kwambiri wolowera njira:

Mlongoti uli ndi ma radiation osiyanasiyana kapena mphamvu zolandirira mayendedwe osiyanasiyana mumlengalenga, komwe ndi kuwongolera kwa mlongoti. Malinga ndi kuwongolera kosiyana, mlongoti uli ndi mitundu iwiri ya omnidirectional ndi directional.

Mlongoti wa Omnidirectional:

Mlongoti wa Omnidirectional, ndiye kuti, munjira yopingasa ngati 360 ° ma radiation ofanana, ndiye kuti, omwe nthawi zambiri amanenedwa kuti sali olunjika, munjira yowongoka ngati m'lifupi mwake mwa mtengowo, makamaka, kucheperako kwa lobe m'lifupi, ndikokulirapo. phindu.

Directional antenna:

Directional mlongoti, mu njira yopingasa ya mitundu ingapo ya ma radiation aang'ono, ndiye kuti, kuwongolera kwanthawi zonse, mumayendedwe oyima a m'lifupi mwa mtengowo, wofanana ndimlongoti wa omnidirectional, kuchepera kwa lobe m'lifupi, kumapindulanso kwambiri. Antenna yolowera nthawi zambiri imagwiritsidwa ntchito pamakina olankhulirana mtunda wautali, malo ang'onoang'ono ofikira, kachulukidwe chandamale chachikulu komanso kugwiritsa ntchito pafupipafupi.

Mfundo yogwira ntchito

Mlongoti wa Omnidirectional udzatumiza zizindikiro kumbali zonse, kutsogolo ndi kumbuyo zimatha kulandira chizindikiro, mlongoti wolunjika uli ngati mbale yowonetsera kumbuyo kwa chigoba cha antenna, chizindikirocho chikhoza kuperekedwa kutsogolo, chizindikiro chowombera kumbuyo ndicho. kutsekedwa ndi chowonetsera ndikuwonetsera kutsogolo, kulimbitsa mphamvu ya chizindikiro kutsogolo.

Sankhani malinga ndi zochitikazo

Posankha mlongoti, ngati masiteshoni angapo akufunika kukhutitsidwa ndipo masiteshoni awa amagawidwa mbali zosiyanasiyana za AP,nyanga za omnidirectionalkufunika kugwiritsidwa ntchito. Monga: nyumba, masitolo, malo oimika magalimoto.

Ngati imayikidwa kumbali imodzi, tikulimbikitsidwa kugwiritsa ntchito mlongoti wolunjika; Monga: ngalande, zipululu, madera amigodi, makonde.

Kusamala Kuyika

Kutsogolo kwa mlongoti wa mbale yayikulu imayang'anizana ndi komwe kuli malo akutali ndipo imayikidwa motalika momwe mungathere, ndipo mtunda wakuwona pakati pa mlongoti ndi malowo ndi wabwino momwe mungathere (wowoneka ndi maso, kupewa zopinga pakati pawo. ).

Lintratek imapereka "njira yoyimitsa imodzi yolumikizira ma foni am'manja" ntchito, kuphatikiza kufananiza kwazinthu, kupanga mzere, kukhazikitsa ndi kutumiza, komanso ntchito yapadera yogulitsa pambuyo pogulitsa, kuti makasitomala azikhala omasuka.
