Waa maxay celiyaha
Ku celisku waa aaladda gudbinta isgaadhsiinta raadiyaha oo leh shaqada helitaanka iyo baahinta calaamadaha shabakada taleefanka gacanta.Waxaa inta badan loo isticmaalaa meelaha ay calaamada saldhiga saldhiga aad u liidato.Waxay xoojisaa calaamada saldhiga saldhiga ka dibna u gudbisa meelaha fog iyo kuwa ka sii balaadhan, si ay u balaadhiso daboolida shabakada.baaxadda
Ku celceliyaasha ayaa ah xalka ugu fiican ee lagu kordhinayo daboolida shabakadaha isgaarsiinta.Marka la barbardhigo saldhigyada saldhigga, waxay leeyihiin faa'iidooyinka qaab-dhismeedka fudud, maalgelin yar, iyo rakibid sahlan.Waxaa si weyn loogu isticmaali karaa meelaha indhoolayaasha ah iyo meelaha daciifka ah ee ay adag tahay in la daboolo, sida xarumaha dukaameysiga iyo garoomada diyaaradaha., Saldhigyada, Garoomada, Tareenada dhulka hoostiisa mara, Wadooyinka waaweyn iyo meelo kale si kor loogu qaado tayada isgaadhsiinta iyo xalinta dhibaatooyinka sida wicitaanada la soo diro.
WorkingPxujo
Hawsha aasaasiga ah ee soo-celiyaha waa kor u qaadka signalka RF.Mabda'a aasaasiga ah ee shaqadeeda waa in la isticmaalo anteenada hore (anteenada deeqaha) si ay u hesho calaamada hoose ee saldhiga saldhiga soo celinta, ku kordhiso signalka waxtarka leh iyada oo loo marayo acod-weyneeye dhawaq yar, xakamee calaamada qaylada ee calaamadda, oo wanaaji saamiga signal-ilaa-qeylada (S/N);Kadibna waxaa hoos loo rogaa calaamadda soo noqnoqda dhexdhexaadka ah, oo lagu sifeeyo afilter, oo lagu xoojiyey inta jeer ee dhexdhexaadka ah, ka dibna kor loo beddelayo inta jeer ee raadiyaha, lagu xoojiyey cod-weyneeye, oo lagu gudbiyo saldhigga mobaylka anteenada gadaal (anteenada dib u gudbinta);isla mar ahaantaana, waxaa hela anteenada gadaale Calaamadda kor u kaca ee saldhigga mobaylka waxaa lagu farsameeyaa isku xirka kor u qaadida ee dhinaca ka soo horjeeda: taas oo ah, waxay dhex martaacod-weyneeye dhawaq yar, hoos-u-beddele,filter, Mid-amplifier, kor-converter, iyo cod-weyneeye ka dibna waxaa lagu gudbiyaa saldhigga saldhigga, si loo gaaro xiriirka ka dhexeeya saldhigga saldhigga iyo saldhigga moobaylka.Isgaarsiinta labada dhinac.
Nooca soo noqnoqda
(1) GSM-ku celcelinta isgaadhsiinta mobilada
Ku celcelinta GSM waa hab lagu xalliyo dhibaatada indhoolayaasha ishaarada ee ay keento daboolida saldhiga saldhiga.Dejinta soo-celinta ma aha oo kaliya hagaajinta caymiska, laakiin sidoo kale waxay si weyn u yaraynaysaa kharashka maalgashiga saldhigyada saldhiga.
(2) CDMA rugta ku celiska ah ee isgaarsiinta mobaylka
Soo-celinta CDMA waxay baabi'in kartaa aagagga hadhka dibadda ee gudaha ee magaalooyinka ay sababto saamaynta dhismayaasha dhaadheer.Soo-celiyeyaasha CDMA waxay ballaarin karaan daboolida saldhigyada CDMA waxayna si weyn u badbaadin karaan maalgashiga dhismaha shabakada CDMA.
(3) GSM/CDMA xarun ku celiska fiber indhaha
Fiber optic relay soo celinta isgaarsiinta moobiilka wuxuu ka kooban yahay laba qaybood: mashiinka dhow ee u dhow saldhigga saldhigga iyo mashiinka fog ee u dhow aagga daboolka.Dib-u-soo-celinta fiber-ka indhaha ayaa leh hawlo ay ka mid yihiin balaadhtanka, xulashada band, xulashada band, iyo xulashada inta jeer.
