Chowonjezera chizindikiro cha foni yam'manja, chomwe chimadziwikanso kuti chobwerezabwereza, chimapangidwa ndi ma antenna olumikizirana, RF duplexer, amplifier ya phokoso lotsika, chosakanizira, ESC attenuator, fyuluta, amplifier yamagetsi ndi zida zina kapena ma module kuti apange maulalo okulitsa a uplink ndi downlink.
Chowonjezera chizindikiro cha foni yam'manja ndi chinthu chopangidwa mwapadera kuti chithetse vuto la chizindikiro cha foni yam'manja. Popeza zizindikiro za foni yam'manja zimadalira kufalikira kwa mafunde amagetsi kuti zikhazikitse kulumikizana, chifukwa cha kutsekedwa kwa nyumba, m'nyumba zina zazitali, m'zipinda zapansi panthaka ndi malo ena, m'masitolo ena, m'malesitilanti, m'malo osangalalira monga karaoke, sauna ndi massage, mapulojekiti achitetezo cha ndege zapamadzi, masiteshoni apansi panthaka, ndi zina zotero, m'malo awa, zizindikiro za foni yam'manja sizingafikire ndipo mafoni am'manja sangagwiritsidwe ntchito.
Chowonjezera chizindikiro cha foni yam'manja cha Lintratekangathetse mavutowa bwino kwambiri. Bola ngati chipangizo cholimbikitsira ma signal a foni yam'manja chayikidwa pamalo enaake, anthu amatha kulandira ma signal abwino a foni yam'manja kulikonse pamene mukuzungulira dera lonselo. Nayi chithunzi chongosonyeza momwe cholimbikitsira ma phone chimagwira ntchito.
Mfundo yaikulu ya ntchito yake ndi iyi: kugwiritsa ntchito antenna yopita patsogolo (antenna yopereka) kuti mulandire 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-mpaka-phokoso (chiŵerengero cha S/N). ); kenako kusinthidwa kukhala chizindikiro cha ma frequency apakati, chosefedwa ndi fyuluta, chokwezedwa pa ma frequency apakati, kenako kusinthidwa kukhala ma frequency a wailesi posintha ma frequency, chokwezedwa ndi amplifier yamphamvu, ndikutumizidwa ku siteshoni yoyenda ndi antenna yakumbuyo (antenna yobwezeretsanso); nthawi yomweyo, antenna yakumbuyo imagwiritsidwa ntchito. Chizindikiro cha uplink cha siteshoni yoyenda chimalandiridwa, ndipo chimakonzedwa ndi ulalo wa uplink amplification m'njira yotsutsana: ndiko kuti, chimatumizidwa ku siteshoni yoyambira kudzera mu amplifier ya phokoso lotsika, downconverter, fyuluta, amplifier yapakati, upconverter, ndi amplifier yamphamvu. Ndi kapangidwe kameneka, kulumikizana kwa njira ziwiri pakati pa siteshoni yoyambira ndi siteshoni yoyenda kungakhale kotheka.
Malangizo ndi njira zodzitetezera pakukhazikitsa:
1. Kusankha chitsanzo: Sankhani chitsanzo choyenera malinga ndi kukula kwake ndi nyumba zomwe zilimo.
2. Ndondomeko yogawa ma antenna: Gwiritsani ntchito ma antenna a Yagi olunjika panja, ndipo malangizo a ma antenna ayenera kuloza ku siteshoni yotumizira ma transmitter momwe mungathere kuti mupeze zotsatira zabwino kwambiri zolandirira. Ma antenna olunjika angagwiritsidwe ntchito mkati, ndipo kutalika kwa kukhazikitsa ndi mamita 2-3 (Kuchuluka kwa ma antenna ndi malo ake kumadalira malo amkati ndi kapangidwe ka mkati), antenna imodzi yokha yamkati iyenera kuyikidwa kuti ikhale yopanda chopinga mkati yosakwana mamita 300, ma antenna awiri amkati amafunika pa mamita 300-500, ndipo atatu amafunika pa mamita 500 mpaka 800.
3. Kukhazikitsa chilimbikitso cha chizindikiro cha foni yam'manja: nthawi zambiri kumayikidwa pamtunda woposa mamita awiri kuchokera pansi. Mtunda pakati pa malo oyika zida ndi ma antenna amkati ndi akunja uyenera kuyendetsedwa ndi mtunda waufupi kwambiri (ngati chingwe chili chachitali, chizindikirocho chimachepa kwambiri) kuti zitheke bwino kwambiri.
4. Kusankha mawaya: muyezo wa chowonjezera chizindikiro cha wailesi ndi wailesi yakanema (ndi TV ya chingwe) ndi 75Ω, koma chowonjezera chizindikiro cha foni yam'manja ndi makampani olumikizirana, ndipo muyezo wake ndi 50Ω, ndipo kulephera kolakwika kudzawononga zizindikiro za dongosolo. Kukhuthala kwa waya kumatsimikiziridwa malinga ndi momwe zinthu zilili pamalopo. Chingwe chikakhala chachitali, wayawo umakhala wolimba kwambiri kuti achepetse kuchepa kwa chizindikiro. Kugwiritsa ntchito waya wa 75Ω kuti wolandila ndi waya asagwirizane kudzawonjezera mafunde oyima ndikuyambitsa mavuto ambiri osokoneza. Chifukwa chake, kusankha waya kuyenera kusiyanitsidwa malinga ndi makampani.
Chizindikiro chomwe chimatumizidwa ndi antenna yamkati sichingalandiridwe ndi antenna yakunja, zomwe zimapangitsa kuti imadzikwiyitsa yokha. Kawirikawiri, antenna ziwirizi zimalekanitsidwa ndi mamita 8 kuti zipewe kudzikwiyitsa zokha.
Lintratek, Konzani mwaukadaulo mavuto a chizindikiro cha foni yam'manja! Chonde thandizaniLumikizanani nafeza utumiki kwa makasitomala.
