Foni yam'manja yowonjezera chizindikiro, yomwe imadziwikanso kuti repeater, imapangidwa ndi tinyanga zoyankhulirana, RF duplexer, amplifier ya phokoso lochepa, chosakanizira, ESC attenuator, fyuluta, amplifier mphamvu ndi zigawo zina kapena ma modules kuti apange maulalo a uplink ndi downlink amplification.
Foni yam'manja chizindikiro cholimbikitsa ndi chinthu chopangidwa mwapadera kuti chithetse mawonekedwe akhungu amtundu wa foni yam'manja. Popeza ma foni am'manja amadalira kufalikira kwa mafunde amagetsi kuti akhazikitse kulumikizana, chifukwa cha kutsekeka kwa nyumba, m'nyumba zina zazitali, zipinda zapansi ndi malo ena, malo ogulitsira, malo odyera, malo osangalalira monga karaoke, sauna ndi kutikita minofu, ntchito zodzitchinjiriza zapansi panthaka, masiteshoni apansi panthaka, etc.
Lintratek foni yam'manja yowonjezera chizindikiroakhoza kuthetsa mavutowa bwino kwambiri. Malingana ngati foni yam'manja yowonjezera chizindikiro cha foni imayikidwa pamalo enaake, anthu amatha kulandira chizindikiro chabwino cha foni paliponse pamene mukuphimba dera lonselo. Nachi chithunzi chongowonetsa momwe chilimbikitso cha mafoni chimagwirira ntchito.
Mfundo yaikulu ya ntchito yake ndi: gwiritsani ntchito mlongoti wakutsogolo (mlongoti wopereka ndalama) kuti mulandire chizindikiro chotsika cha siteshoni yoyambira kubwereza, kukulitsa chizindikiro chothandizira kudzera pa amplifier ya phokoso lochepa, kupondereza chizindikiro cha phokoso mu siginecha, ndikusintha chiŵerengero cha phokoso ndi phokoso (chiŵerengero cha S/N). ); ndiye kutsika-kutembenuzidwa ku chizindikiro chapakati chapakati, chosefedwa ndi fyuluta, kukulitsidwa pafupipafupi, ndiyeno mmwamba-kutembenuzidwa ku mawailesi pafupipafupi ndi kusuntha pafupipafupi, kumakulitsidwa ndi amplifier ya mphamvu, ndikutumizidwa ku siteshoni yam'manja ndi mlongoti wakumbuyo (retransmission antenna); nthawi yomweyo, mlongoti wakumbuyo umagwiritsidwa ntchito. Chizindikiro cha uplink cha siteshoni yam'manja chimalandiridwa, ndipo chimakonzedwa ndi ulalo wa uplink amplification motsatira njira ina: ndiye kuti, imatumizidwa ku siteshoni yapansi kudzera pa phokoso lochepa la amplifier, downconverter, fyuluta, amplifier wapakatikati, upconverter, ndi amplifier mphamvu. Ndi mapangidwe awa, kulumikizana kwanjira ziwiri pakati pa siteshoni yoyambira ndi siteshoni yam'manja kungakhale kotheka.
Malangizo oyika ndi chenjezo:
1. Kusankhidwa kwachitsanzo: Sankhani chitsanzo choyenera malinga ndi kuphimba ndi zomangamanga.
2. Dongosolo logawa mlongoti: Gwiritsani ntchito tinyanga ta Yagi panja, ndipo mayendedwe a tinyanga akuyenera kuloza potengera potengera momwe mungathere kuti mukwaniritse bwino kulandirira. Tinyanga za Omnidirectional zitha kugwiritsidwa ntchito m'nyumba, ndipo kutalika kwake ndi 2-3 metres (Kuchuluka kwa mlongoti ndi malo kumadalira malo amkati ndi m'nyumba), mlongoti umodzi wokha wamkati uyenera kuyikidwa kuti ukhale wosasunthika m'nyumba zosakwana 300 masikweya mita, tinyanga 2 zamkati zimafunikira pamtunda wa 300 mpaka 300 mpaka 300 sq. 800 lalikulu mita.
3. Foni yam'manja chizindikiro chilimbikitso unsembe: zambiri anaika pa oposa 2 mamita pamwamba pa nthaka. Mtunda wapakati pa malo oyika zida ndi tinyanga zamkati ndi zakunja uyenera kuyendetsedwa ndi mtunda waufupi kwambiri (ndi chingwe chachitali, kutsitsa kwamphamvu kwambiri) kuti mukwaniritse bwino.
4. Kusankhidwa kwa mawaya: muyezo wa feeder wa chizindikiro chowonjezera cha wailesi ndi televizioni (ndi chingwe TV) ndi 75Ω, koma chothandizira chizindikiro cha foni yam'manja ndi makampani olankhulana, ndipo muyezo wake ndi 50Ω, ndipo kusokoneza kolakwika kudzasokoneza zizindikiro za dongosolo. Kuchuluka kwa waya kumatsimikiziridwa malinga ndi momwe zilili pa malo. Chingwecho chitalikira, ndiye kuti waya wokhuthala kuti achepetse kutsika kwa siginecha. Kugwiritsa ntchito waya wa 75Ω kuti mupangitse wolandirayo ndi waya asagwirizane kumawonjezera kuyimirira ndikuyambitsa zovuta zosokoneza. Choncho, kusankha kwa waya kuyenera kukhala kosiyana malinga ndi makampani.
Chizindikiro chotumizidwa ndi mlongoti wamkati sichikhoza kulandiridwa ndi mlongoti wakunja, zomwe zingayambitse kudzisangalatsa. Nthawi zambiri, tinyanga ziwirizi zimasiyanitsidwa ndi mita 8 kuti tipewe kudzisangalatsa.
Lintratek, thetsani mwaukadaulo zovuta zamawu a foni yam'manja! ChondeLumikizanani nafekwa kasitomala.
