Chinosimudzira masaini efoni, chinozivikanwawo serepeater, chinoumbwa nemaantenna ekutaurirana, RF duplexer, amplifier yeruzha rwakaderera, mixer, ESC attenuator, filter, power amplifier nezvimwe zvikamu kana mamodule ekuumba uplink ne downlink amplification links.
Chinosimudzira masaini efoni mbozha chigadzirwa chakagadzirirwa kugadzirisa nzvimbo isina ruzivo rwemasaini efoni mbozha. Sezvo masaini efoni achitsamira pakupararira kwemafungu emagetsi kuti agadzire kubatana kwekutaurirana, nekuda kwekuvharika kwezvivakwa, mune dzimwe zvivakwa zvirefu, pasi pedzimba nedzimwe nzvimbo, mune dzimwe nzvimbo dzekutenga, maresitorendi, nzvimbo dzevaraidzo dzakadai sekaraoke, sauna uye masaji, mapurojekiti ekudzivirira mhepo dzepasi pevhu, zviteshi zvepasi pevhu, nezvimwewo, munzvimbo idzi, masaini efoni haagone kusvikwa uye nharembozha hadzigone kushandiswa.
Chinosimudzira chiratidzo chefoni yeLintratekinogona kugadzirisa matambudziko aya zvakanaka. Chero bedzi sisitimu yekusimudzira masaini efoni yakaiswa panzvimbo chaiyo, vanhu vanogona kugamuchira masaini efoni kwese kwese paunenge uchitenderera nzvimbo yese ipapo. Heino mufananidzo unoratidza kuti mobile booster inoshanda sei.
Nheyo huru yebasa rayo ndeiyi: shandisa antenna yekumberi (antenna yemupi) kuti ugamuchire chiratidzo chedownlink chechiteshi chepasi mu repeater, wedzera chiratidzo chinobatsira kuburikidza ne amplifier yeruzha rwakaderera, dzvanya chiratidzo cheruzha chiri muchiratidzo, uye vandudza chiyero chesignal-to-noise (S/N ratio). ); wobva wadzikiswa kuita chiratidzo chepakati pefrequency, chakasefetwa nefirita, chakakwidziridzwa pafrequency yepakati, wobva wakwidziridzwa kuredio frequency ne frequency shifting, chakakwidziridzwa ne amplifier yesimba, uye choendeswa kunharembozha ne antenna yekumashure (antenna yekudzoreredza); panguva imwe chete, antenna yekumashure inoshandiswa. Chiratidzo cheuplink chechiteshi chepasi chinogamuchirwa, uye chinogadziriswa ne uplink amplification link munzira yakatarisana: ndiko kuti, chinotumirwa kuchiteshi chepasi kuburikidza ne amplifier yeruzha rwakaderera, downconverter, firita, intermediate amplifier, upconverter, uye power amplifier. Nekugadzira uku, kutaurirana kwenzira mbiri pakati pechiteshi chepasi nechiteshi chepasi kunogona kuitika.
Mirayiridzo yekuisa uye matanho ekudzivirira:
1. Sarudzo yemuenzaniso: Sarudza muenzaniso wakakodzera zvichienderana nehupamhi hwechivako uye zvivakwa.
2. Chirongwa chekugovera maAntena: Shandisa maantenna eYagi akananga panze, uye divi remaantenna rinofanira kunongedzera kunzvimbo inotumira mashoko zvakanyanya sezvinobvira kuti uwane mhedzisiro yakanaka yekugamuchira. Maantenna eOmnidirectional anogona kushandiswa mukati, uye kukwirira kwekuisa maantenna i2-3 metres (Huwandu hwemaantenna nenzvimbo zvinoenderana nenzvimbo yemukati uye chimiro chemukati), antenna imwe chete yemukati inofanirwa kuiswa yenzvimbo isina kuvharwa yemukati isingasviki 300 square metres, maantenna maviri emukati anodiwa kune nzvimbo inosvika 300-500 square metres, uye matatu anodiwa kune nzvimbo inosvika 500 kusvika 800 square metres.
3. Kuisa chibooster chefoni: chinowanzoiswa panzvimbo inopfuura mamita maviri kubva pasi. Kureba pakati penzvimbo yekuisa michina neantenna dzemukati nedzekunze kunofanirwa kuendeswa kure kupfupi (kana tambo yakareba, kudzikira kwechiratidzo kwakanyanya) kuti pave nemhedzisiro yakanaka.
4. Kusarudzwa kwewaya: chiyero che feeder ye signal booster yeredhiyo neterevhizheni (inonzi cable TV) i75Ω, asi nharembozha signal booster ndiyo indasitiri yekutaurirana, uye chiyero chayo i50Ω, uye impedance isiriyo ichakanganisa zviratidzo zve system. Ukobvu hwewaya hunotsanangurwa zvichienderana nemamiriro chaiwo ari panzvimbo. Kana waya yakareba, ukobvu hwewaya hunowedzera kuderedza kuderera kwechiratidzo. Kushandisa waya ye75Ω kuita kuti host newaya zvisawirirane kunowedzera kumira kwemafungu uye kukonzera matambudziko akawanda ekupindira. Saka, kusarudzwa kwewaya kunofanirwa kusiyaniswa zvichienderana neindasitiri.
Chiratidzo chinotumirwa neantenna yemukati hachigone kugamuchirwa neantenna yekunze, izvo zvinozokonzera kuzvifadza. Kazhinji, antenna mbiri idzi dzinoparadzaniswa nemamita masere kudzivirira kuzvifadza.
