Kodi Chizindikiro cha Foni Yam'manja Chimachokera Kuti?

Q1. Kodi chizindikiro cha foni yam'manja chimachokera kuti?
Ndikukhulupirira kuti anthu ambiri amva za mawu awiriwasiteshoni ya maziko kapena siteshoni yazizindikiro (nsanja), koma kwenikweni ndi chinthu chimodzi. Chizindikiro cha foni yam'manja chimatumizidwa kudzera mu chinthu chomwe timachitcha siteshoni yoyambira.

Q2. Kodi mafunde a electromagnetic ndi chiyani?
Mwachidule, mafunde amagetsi ndi mafunde a tinthu tozungulira omwe amachokera ndikutulutsidwa mumlengalenga ndi magetsi ndi maginito omwe ali mu gawo komanso olunjika kwa wina ndi mnzake. Ndi maginito amagetsi omwe amafalikira mu mawonekedwe a mafunde ndipo ali ndi mafunde awiriawiri. Liwiro lofalitsa: liwiro la mulingo wa kuwala, palibe cholumikizira chofalitsa chomwe chikufunika (Mafunde amawu amafunika cholumikizira). Mafunde amagetsi amayamwa ndi kuwonekera akakumana ndi chitsulo, ndipo amafooka akatsekedwa ndi nyumba, ndipo amafooka akamawombedwa ndi mphepo, mvula komanso mabingu. Kutalika kwa mafunde kukakhala kochepa komanso kuchuluka kwa mafunde amagetsi, deta imatumizidwa nthawi iliyonse.

Q3. Kodi tingakonze bwanji chizindikirocho bwino?
Pakadali pano pali njira ziwiri. Njira imodzi ndi kudziwitsa woyendetsa wanu kuti chizindikiro chapafupi sichili bwino, ndipo dipatimenti yokonza maukonde idzapita kukayesa mphamvu ya chizindikiro. Ngati mphamvu ya chizindikiro sichikukwaniritsa zofunikira, woyendetsa adzamanga malo oyambira pano kuti akonze netiweki yanu.

Chimodzi ndi kugwiritsa ntchito chida cholimbikitsira mawu pafoni yam'manja. Mfundo yake ndikugwiritsa ntchito antenna yopita patsogolo (antenna yopereka) kuti ilandire chizindikiro cha downlink cha siteshoni yoyambira mu repeater, kukulitsa chizindikiro chothandiza kudzera mu amplifier ya phokoso lotsika, kuletsa chizindikiro cha phokoso mu chizindikirocho, ndikukweza chiŵerengero cha chizindikiro-ku-phokoso (S/N); kenako kusinthidwa kukhala chizindikiro cha ma frequency apakati, chosefedwa ndi fyuluta, chokulitsidwa ndi ma frequency apakati, kenako kusinthidwa ma frequency ndikusinthidwa kukhala ma frequency a wailesi, chokulitsidwa ndi amplifier yamphamvu, ndikutumizidwa ku siteshoni yam'manja ndi antenna yakumbuyo (antenna yotumiziranso); Nthawi yomweyo, chizindikiro cha uplink cha siteshoni yam'manja chimalandiridwa ndi antenna yakumbuyo, ndikukonzedwa ndi ulalo wa uplink amplification m'njira yotsutsana: ndiko kuti, chimatumizidwa ku siteshoni yam'munsi kudzera mu amplifier ya phokoso lotsika, chosinthira mawu pansi, fyuluta, amplifier yapakati, chosinthira mawu pamwamba, ndi chowonjezera mphamvu, motero Kukwaniritsa kulumikizana kwa njira ziwiri pakati pa siteshoni yam'munsi ndi siteshoni yam'manja.

Ma amplifiers a mafoni a m'manja angagwiritsidwe ntchito m'madera odzaza matauni, m'mphepete mwa mizinda ndi m'madera akumidzi, komanso m'madera akumidzi. Ndi abwino kwambiri. Ndi njira iti yomwe mumakonda?

Linchuang ndi kampani yapamwamba kwambiri yomwe imatumikira ogwiritsa ntchito oposa 1 miliyoni m'maiko ndi madera 155 padziko lonse lapansi. Pankhani yolumikizirana pafoni, timalimbikitsa kupanga zatsopano zokhudzana ndi zosowa za makasitomala kuti tithandize makasitomala kuthetsa zosowa za zizindikiro zolumikizirana! Linchuang yadzipereka kukhala mtsogoleri mumakampani ofooka olumikizirana zizindikiro, kuti pasakhale malo osawoneka bwino padziko lonse lapansi, ndipo aliyense athe kulankhulana popanda zopinga!
