Kodi Chizindikiro cha Foni Yam'manja Chimachokera Kuti?

Q1. Kodi chizindikiro cha foni yam'manja chimachokera kuti?
Ndikukhulupirira kuti anthu ambiri amvapo za mawu awiriwabase station kapena sign station (nsanja), koma kwenikweni ndi chinthu chimodzi. Chizindikiro cha foni yam'manja chimafalitsidwa kudzera mu chinthu chomwe timachitcha kuti base station.

Q2. Kodi electromagnetic wave ndi chiyani?
Kunena mwachidule, mafunde a electromagnetic ndi mafunde a tinthu tating'onoting'ono tomwe amatengedwa ndikutulutsidwa mumlengalenga ndi minda yamagetsi ndi maginito yomwe ili mu gawo ndi perpendicular kwa wina ndi mnzake. Ndi minda yamagetsi yamagetsi yomwe imafalikira mu mawonekedwe a mafunde ndipo imakhala ndi mawonekedwe amitundu iwiri. Kuthamanga kwa kufalikira: kuthamanga kwa mulingo wa kuwala, palibe njira yotsatsira yomwe imafunikira (Mafunde amawu amafunikira sing'anga). Mafunde a electromagnetic amatengeka ndikuwonetseredwa akakumana ndi zitsulo, ndipo amafooka akatsekeredwa ndi nyumba, ndipo amafooka ngati kuli mphepo, mvula komanso mabingu. Kufupikitsa kwa kutalika kwa mafunde ndi kukweza kwafupipafupi kwa mafunde a electromagnetic, m'pamenenso deta imafalitsidwa pa nthawi imodzi.

Q3. Kodi tingakweze bwanji chizindikiro?
Pano pali njira ziwiri. Chimodzi ndikudziwitsa opareshoni yanu kuti chizindikiro chakumaloko sichabwino, ndipo dipatimenti yokhathamiritsa maukonde ipita kukayesa mphamvu ya siginecha. Ngati mphamvu ya siginecha siyikukwaniritsa zofunikira, wogwiritsa ntchitoyo amamanga malo oyambira pano kuti akonze maukonde anu.

Chimodzi ndicho kugwiritsa ntchito chokulitsa chizindikiro cha foni yam'manja. Mfundo yake ndikugwiritsa ntchito mlongoti wakutsogolo (mlongoti wopereka ndalama) kuti mulandire chizindikiro chotsika cha siteshoni yoyambira kubwereza, kukulitsa chizindikiro chothandiza kudzera pa amplifier ya phokoso lochepa, kupondereza chizindikiro cha phokoso mu siginecha, ndikusintha chizindikiro cha phokoso (S/N); ndiye kutsika-kutembenuzidwa ku siginecha yapakatikati, yosefedwa ndi fyuluta, yokulitsidwa ndi ma frequency apakatikati, ndiyeno imasinthidwa pafupipafupi ndikusinthidwa kukhala ma frequency a wailesi, imakulitsidwa ndi amplifier yamagetsi, ndikutumizidwa ku siteshoni yam'manja ndi mlongoti wakumbuyo (kutumizanso mlongoti); Nthawi yomweyo, chizindikiro cha uplink cha siteshoni yam'manja imalandiridwa ndi mlongoti wakumbuyo, ndikukonzedwa ndi ulalo wa uplink amplifier motsatira njira ina: ndiye kuti, imatumizidwa ku siteshoni yoyambira kudzera pa amplifier yaphokoso lotsika, chosinthira chotsika, fyuluta, amplifier wapakatikati, chosinthira chokwera, ndi cholumikizira magetsi, potero Kukwaniritsa malo olumikizirana.

Ma amplifiers a foni yam'manja atha kugwiritsidwa ntchito m'matauni owundana, m'mphepete mwamatauni ndi m'midzi, komanso kumidzi. Ndi yabwino kwambiri. Kodi mumakonda njira iti?

Linchuang ndi bizinesi yapamwamba kwambiri yomwe imagwiritsa ntchito ogwiritsa ntchito oposa 1 miliyoni m'maiko 155 ndi zigawo padziko lonse lapansi. Pankhani yolumikizana ndi mafoni, timalimbikira kupanga zatsopano pazosowa zamakasitomala kuti tithandizire makasitomala kuthana ndi zosowa zamakina olumikizirana! Linchuang wadzipereka kukhala mtsogoleri wamakampani ofooka olumikizira ma siginecha, kuti pasakhale malo akhungu padziko lapansi, ndipo aliyense angathe kulumikizana popanda zopinga!
