Gusubiramo ni iki
Gusubiramo ni igikoresho cyo gutumanaho kuri radio gifite umurimo wo kwakira no kongera ibimenyetso bya terefone igendanwa. Ikoreshwa cyane mubice aho ibimenyetso fatizo byerekana ibimenyetso bidakomeye. Yongera ibimenyetso bya sitasiyo fatizo hanyuma ikohereza ahantu kure kandi mugari, bityo ikagura imiyoboro. urugero.
Abasubiramo ni igisubizo cyiza cyo kwagura imiyoboro y'itumanaho. Ugereranije na sitasiyo fatizo, bafite ibyiza byuburyo bworoshye, ishoramari rito, no kwishyiriraho byoroshye. Birashobora gukoreshwa cyane mubice byimpumyi hamwe n’intege nke bigoye gutwikirwa, nk'ahantu hacururizwa no ku bibuga byindege. , sitasiyo, stade, metero, umuhanda munini nahandi kugirango tunoze ireme ryitumanaho no gukemura ibibazo nko guhamagarwa.
WorkingPrinciple
Igikorwa cyibanze cyisubiramo ni imbaraga za signal ya RF. Ihame shingiro ryimirimo yaryo ni ugukoresha antenne yimbere (antenne y'abaterankunga) kugirango wakire ibimenyetso byamanuka bya sitasiyo fatizo mubisubiramo, byongere ibimenyetso byingirakamaro binyuze aurusaku rwinshi, guhagarika ibimenyetso byurusaku mubimenyetso, no kunoza igipimo cy-urusaku (S / N); Noneho iramanurwa-ihindurwamo ikimenyetso giciriritse hagati, cyungururwa na amuyunguruzi, byongerewe inshuro zingana, hanyuma bikazamurwa kuri radiyo yumurongo wa radiyo, byongerwaho imbaraga nimbaraga, hanyuma bigashyikirizwa kuri terefone igendanwa na antene isubira inyuma (antenne retransmission); icyarimwe, yakirwa na antenne isubira inyuma Ikimenyetso cyo kuzamura sitasiyo igendanwa gitunganywa na uplink amplification ihuza inzira itandukanye: ni ukuvuga ko inyura kuriurusaku rwinshi, kumanura,muyunguruzi, hagati-yongerera imbaraga, hejuru-ihindura, hamwe nimbaraga zongera imbaraga hanyuma ikoherezwa kuri sitasiyo fatizo, bityo bikagera ku itumanaho hagati ya sitasiyo fatizo na sitasiyo igendanwa. Itumanaho ryuburyo bubiri.
Ubwoko bw'isubiramo
（1） Gusubiramo itumanaho rya GSM
GSM isubiramo nuburyo bwo gukemura ikibazo cyibimenyetso byahumye biterwa na sitasiyo fatizo. Gushiraho abasubiramo ntibishobora kunoza ubwishingizi gusa, ariko kandi birashobora kugabanya cyane ikiguzi cyo gushora imari muri sitasiyo fatizo.
(2) CDMA itumanaho rya terefone igendanwa
CDMA isubiramo irashobora gukuraho ibimenyetso byo hanze byerekana igicucu mumijyi iterwa ningaruka zinyubako ndende. CDMA isubiramo irashobora kwagura ubwishingizi bwa sitasiyo ya CDMA kandi ikabika cyane ishoramari mukubaka imiyoboro ya CDMA.
(3) GSM / CDMA optique ya fibre isubiramo
Fibre optique relay itumanaho rya terefone igendanwa igizwe nibice bibiri: imashini yegeranye-hafi ya sitasiyo fatizo hamwe na mashini ya kure yegereye aho ikwirakwizwa. Gusubiramo fibre optique ifite imikorere nka Broadband, guhitamo bande, guhitamo bande, no guhitamo inshuro.
