Nharembozha chiratidzo booster, inozivikanwawo seanodzokorora, inoumbwa neantennas ekutaurirana, RF duplexer, yakaderera ruzha amplifier, musanganiswa, ESC attenuator, sefa, simba amplifier uye zvimwe zvikamu kana ma modules ekugadzira uplink uye downlink amplification link.
Nharembozha inosimudzira chiratidzo chigadzirwa chakanyatsogadzirirwa kugadzirisa nzvimbo yebofu yechiratidzo chenharembozha. Sezvo masaini enharembozha achivimba nekupararira kwemafungu emagetsi kuti atange kutaurirana, nekuda kwekuvharika kwezvivakwa, mune zvimwe zvivakwa zvirefu, dzimba dzepasi nedzimwe nzvimbo, dzimwe nzvimbo dzekutenga, maresitorendi, nzvimbo dzevaraidzo dzakadai sekaraoke, sauna uye masaja, mapurojekiti ekudzivirira mhepo epasi pevhu, zviteshi zvepasi pevhu, nezvimwewo, munzvimbo idzi, masaini enharembozha haagone kusvikwa uye nharembozha hadzigone kushandiswa.
Lintratek nharembozha chiratidzo boosteranogona kugadzirisa matambudziko aya zvakanaka kwazvo. Chero bedzi nharembozha nharembozha inosimudzira system yakaiswa munzvimbo yakati, vanhu vanogona kugashira yakanaka nharembozha chiratidzo pese paunovhara nzvimbo yese ipapo. Heino pikicha yekungoratidza kuti iyo mobile booster inoshanda sei.
Musimboti webasa rayo ndewekuti: shandisa antenna yekumberi (donor antenna) kugashira chiratidzo chekudzika kweiyo base station mune inodzokorora, kukwidziridza iyo inobatsira chiratidzo kuburikidza neyakaderera-ruzha amplifier, kudzvanya chiratidzo cheruzha muchiratidzo, uye kuvandudza chiratidzo-ku-ruzha reshiyo (S/N chiyero). ); ipapo pasi-inoshandurwa kune yepakati frequency chiratidzo, yakasefa nesefa, inokwidziridzwa pane yepakati frequency, uyezve kumusoro-inoshandurwa kune redhiyo frequency nekuchinja-chinja, inokwidziridzwa neiyo simba amplifier, uye inopfuudzwa kunhare mbozha neantenna yekumashure (retransmission antenna); panguva imwecheteyo, antenna yekumashure inoshandiswa. Iyo uplink siginecha yenharembozha inotambirwa, uye inogadziriswa neiyo uplink amplification link munzira yakatarisana: ndiko kuti, inopfuudzwa kune base chiteshi kuburikidza yakaderera ruzha amplifier, downconverter, sefa, yepakati amplifier, upconverter, uye simba amplifier. Nekugadzirwa uku, nzira mbiri dzekukurukurirana pakati peiyo base station uye mobile station inogona kuitika.
Kuisa mirayiridzo uye zvidziviriro:
1. Kusarudzwa kwemuenzaniso: Sarudza muenzaniso wakakodzera maererano nekuvhara uye zvivakwa zvekuvaka.
2. Antenna kugovera hurongwa: Shandisa yakananga Yagi antennas kunze, uye kutungamira kweantenna kunofanirwa kunongedza kune yekutapurirana base chiteshi zvakanyanya sezvinobvira kuti uwane yakanakisa yekugamuchira maitiro. Omnidirectional antennas inogona kushandiswa mukati, uye kureba kwekumisikidza ndeye 2-3 metres (Huwandu hweantenna nenzvimbo zvinoenderana nenzvimbo yemukati uye chimiro chemukati), antenna imwe chete yemukati inoda kuisirwa yemukati isina kuvharika renji isingasviki mazana matatu emamita, maviri emukati antenna anodiwa kune huwandu hwemakumi matatu emamita, kusvika makumi matatu nemakumi matatu. 800 square mita.
3. Nharembozha chiratidzo chekusimudzira kuisirwa: kazhinji yakaiswa pane anopfuura 2 metres pamusoro pevhu. Chinhambwe chiri pakati penzvimbo yekumisikidza yemidziyo uye emukati nekunze antennas inofanirwa kufambiswa nechinhambwe chipfupi (nekurebesa tambo, iyo yakakura yekumisikidza chiratidzo) kuti uwane yakanakisa mhedzisiro.
4. Kusarudzwa kwetambo: chiyero chekudyisa chechiratidzo chekusimudzira redhiyo uye terevhizheni (iyo cable TV) ndeye 75Ω, asi nharembozha inosimudzira nharembozha ndiyo indasitiri yekukurukurirana, uye chiyero chayo ndeye 50Ω, uye iyo impedance isiriyo ichashatisa zviratidzo zvehurongwa. Ukobvu hwetambo hunotarirwa maererano nemamiriro ezvinhu chaiwo panzvimbo. Kurebesa tambo, ndiko kukora kwewaya yekudzikisa kudzikisira kwechiratidzo. Kushandisa 75Ω waya kuita kuti mugadziri uye waya zvisaenderane kuchawedzera mafungu akamira uye kukonzera mamwe matambudziko ekukanganisa. Nokudaro, kusarudzwa kwetambo kunofanira kusiyaniswa maererano neindasitiri.
Chiratidzo chinotumirwa neantenna yemukati haigone kugamuchirwa neantenna yekunze, iyo inokonzera kuzvifadza. Kazhinji, maantenna maviri anoparadzaniswa nemamita masere kudzivirira kuzvifadza.
Lintratek, nehunyanzvi kugadzirisa matambudziko echiratidzo chenharembozha! Ndapotataura nesuzvebasa revatengi.
