Wobwereza ndi chiyani
Wobwereza ndi chipangizo cholumikizirana pawailesi chomwe chimakhala ndi ntchito yolandila ndikukulitsa ma siginecha a foni yam'manja. Amagwiritsidwa ntchito makamaka m'malo omwe chizindikiro choyambira chimakhala chofooka kwambiri. Imakulitsa chizindikiro cha station station kenako ndikuitumiza kumadera akutali komanso okulirapo, motero imakulitsa kufalikira kwa netiweki. kukula.
Repeaters ndi njira yabwino kwambiri yowonjezerera kufalikira kwa maukonde olumikizirana. Poyerekeza ndi masiteshoni oyambira, ali ndi zabwino zamapangidwe osavuta, ndalama zochepa, komanso kukhazikitsa kosavuta. Zitha kugwiritsidwa ntchito kwambiri m'malo akhungu ndi malo ofooka omwe ndi ovuta kubisala, monga masitolo ndi ma eyapoti. , masiteshoni, masitediyamu, njanji zapansi panthaka, misewu yayikulu ndi malo ena kuti apititse patsogolo kulumikizana komanso kuthetsa mavuto monga mafoni otsitsidwa.
WkuchitaPrinciple
Ntchito yofunikira ya wobwereza ndi chowonjezera mphamvu ya RF. Mfundo yayikulu yantchito yake ndikugwiritsa ntchito mlongoti wakutsogolo (mlongoti wopereka) kuti mulandire chizindikiro chotsikirako cha siteshoni yoyambira mu obwereza, kukulitsa chizindikiro chothandiza kudzera muamplifier otsika phokoso, kupondereza chizindikiro cha phokoso mu siginecha, ndikuwongolera chiŵerengero cha chizindikiro-ku-phokoso (S/N); Kenako imasinthidwa kukhala chizindikiro chapakatikati, chosefedwa ndi afyuluta, kukulitsidwa ndi mafupipafupi apakatikati, ndiyeno mmwamba-kutembenuzidwa ku mawailesi afupipafupi, amakulitsidwa ndi amplifier ya mphamvu, ndi kutumizidwa ku siteshoni yam'manja ndi mlongoti wakumbuyo (retransmission antenna); nthawi yomweyo, imalandiridwa ndi mlongoti wakumbuyo Chizindikiro cha uplink cha siteshoni yam'manja chimakonzedwa ndi ulalo wa uplink amplification panjira ina: ndiko kuti, umadutsaamplifier otsika phokoso, pansi-converter,fyuluta, mid-amplifier, up-converter, ndi amplifier mphamvu ndiyeno imatumizidwa ku siteshoni yoyambira, potero kukwaniritsa kulankhulana pakati pa siteshoni yoyambira ndi siteshoni yam'manja. Kulankhulana kwanjira ziwiri.
Mtundu wa Repeater
(1) GSM yobwereza kuyankhulana kwamafoni
GSM repeater ndi njira yothetsera vuto la mawanga akhungu omwe amayambitsidwa ndi kufalikira kwa masiteshoni. Kukhazikitsa obwereza sikungangowonjezera kufalitsa, komanso kuchepetsa kwambiri mtengo woyika ndalama m'malo oyambira.
(2) CDMA yolumikizira mafoni obwereza
Kubwereza kwa CDMA kumatha kuthetseratu madera akunja azithunzi zakunja m'mizinda chifukwa chokhudzidwa ndi nyumba zokwera. Obwereza a CDMA amatha kukulitsa kufalikira kwa masiteshoni a CDMA ndikupulumutsa kwambiri ndalama pakumanga maukonde a CDMA.
(3) GSM/CDMA optical fiber repeater station
Fiber optic relay mobile communication repeater imakhala ndi magawo awiri: makina oyandikira pafupi ndi malo oyambira ndi makina akutali pafupi ndi malo ophimba. Optical fiber repeater ili ndi ntchito monga burodibandi, kusankha bandi, kusankha bandi, ndi kusankha pafupipafupi.
