Terefone igendanwa ya terefone igendanwa, izwi kandi nka repetater, igizwe na antenne y'itumanaho, duplexer ya RF, urusaku ruke rwinshi, ivangavanga, ESC attenuator, akayunguruzo, imbaraga zongera imbaraga hamwe nibindi bice cyangwa modul kugirango bibe byuzuzanya no kumanura.
Ikimenyetso cya terefone igendanwa ni igicuruzwa cyabugenewe kugirango gikemure akarere gahumye ibimenyetso bya terefone igendanwa.Kubera ko ibimenyetso bya terefone igendanwa bishingiye ku gukwirakwiza imiyoboro ya elegitoroniki kugira ngo habeho itumanaho, kubera guhagarika inyubako, mu nyubako zimwe na zimwe ndende, mu nsi yo munsi ndetse n'ahandi, amaduka amwe n'amwe, resitora, ahantu ho kwidagadurira nka karaoke, sauna na massage, munsi y'ubutaka. imishinga yo kurinda ikirere cya gisivili, gariyamoshi, nibindi, aha hantu, ibimenyetso bya terefone igendanwa ntibishobora kugerwaho kandi terefone zigendanwa ntizishobora gukoreshwa.
Lintratek ya terefone igendanwa yerekana ibimenyetsoirashobora gukemura neza ibibazo.Igihe cyose sisitemu yo kuzamura ibimenyetso bya terefone igendanwa yashyizwe ahantu runaka, abantu barashobora kwakira ibimenyetso bya terefone ngendanwa ahantu hose mugihe utwikiriye akarere kose.Hano hari ifoto yerekana gusa uko boster igendanwa ikora.
Ihame shingiro ryimirimo yaryo ni: koresha antenne yimbere (antenne y'abaterankunga) kugirango wakire ibimenyetso byamanuka bya sitasiyo fatizo muri repetater, wongere ibimenyetso byingirakamaro ukoresheje amplifier nkeya, guhagarika ibimenyetso byurusaku mubimenyetso, no kunoza igipimo cyerekana-urusaku (igipimo cya S / N).);hanyuma umanuke uhindurwe kuri signal intera intera intera, uyungururwe nayunguruzo, yongerwe kumurongo mugihe, hanyuma uhindurwe kuri radio yumurongo uhinduranya inshuro, byongerwaho ingufu na amplifier, hanyuma woherezwa kuri sitasiyo igendanwa na antenne isubira inyuma (antenne ya retransmission);icyarimwe, antenne yinyuma ikoreshwa.Ikimenyetso cya uplink cya sitasiyo igendanwa cyakiriwe, kandi gitunganywa na uplink amplification ihuza inzira itandukanye: ni ukuvuga ko yoherezwa kuri sitasiyo fatizo binyuze mu majwi make yongerera urusaku, kumanura ibintu, kuyungurura, kwongera hagati, an upconverter, hamwe nimbaraga zongera imbaraga.Hamwe niki gishushanyo, itumanaho ryibice bibiri hagati ya sitasiyo fatizo na sitasiyo igendanwa birashoboka.
Amabwiriza yo kwishyiriraho no kwirinda:
1. Guhitamo icyitegererezo: Hitamo icyitegererezo gikwiye ukurikije ubwubatsi n'inzu zubaka.
2. Gahunda yo gukwirakwiza Antenna: Koresha icyerekezo cya Yagi antenne hanze, kandi icyerekezo cya antene kigomba kwerekana sitasiyo yoherejwe uko bishoboka kwose kugirango ugere kubikorwa byiza byo kwakira.Antenne ya Omnidirectional irashobora gukoreshwa mumazu, kandi uburebure bwo kwishyiriraho ni metero 2-3 (Umubare wa antenne hamwe n’ahantu biterwa n’imbere mu nzu ndetse n’imiterere y’imbere), antenne imwe yo mu nzu igomba gushyirwaho kugirango inzu itabangamiwe iri munsi ya kare 300 metero, antene 2 zo murugo zirakenewe kuri metero kare 300-500, naho 3 zirakenewe kuri metero kare 500 kugeza 800.
3. Kwishyiriraho terefone igendanwa ya terefone igendanwa: muri rusange yashyizwe kuri metero zirenga 2 hejuru yubutaka.Intera iri hagati yububiko bwibikoresho hamwe na antene yo mu nzu no hanze igomba kunyuzwa hamwe nintera ngufi (hamwe nigihe kirekire, insinga nini yerekana ibimenyetso) kugirango igere ku ngaruka nziza.
4. Guhitamo insinga: igipimo cyo kugaburira ibimenyetso byerekana amaradiyo na tereviziyo (ni televiziyo ya kabili) ni 75Ω, ariko icyuma cyerekana telefone igendanwa ni inganda zitumanaho, kandi igipimo cyacyo ni 50Ω, kandi inzitizi mbi izabikora kwangiza ibipimo bya sisitemu.Ubunini bwinsinga bugenwa ukurikije uko ibintu bimeze kurubuga.Umwanya muremure, insinga nini yo kugabanya attenuation yikimenyetso.Gukoresha insinga ya 75Ω kugirango uwakiriye hamwe ninsinga bidahuye bizongera umuraba uhagaze kandi bitere ibibazo byinshi byo kwivanga.Kubwibyo, guhitamo insinga bigomba gutandukanywa ukurikije inganda.
Ikimenyetso cyoherejwe na antenne yo mu nzu ntigishobora kwakirwa na antenne yo hanze, izatera kwishima.Mubisanzwe, antene ebyiri zitandukanijwe na metero 8 kugirango wirinde kwishima.
Lintratek, ubuhanga bwo gukemura ibibazo bya terefone igendanwa!Nyamunekatwandikirekuri serivisi zabakiriya.
