CellularKu celi
Isgaadhsiinta, ku celisku waa qalab elegtaroonig ah oo hela signalka dibna u gudbiya.Ku celis waxaa loo isticmaalaa in lagu kordhiyo gudbinta si ay calaamaddu u dabooli karto masaafo dheer ama laga helo dhinaca kale ee xannibaadda.
Waxaa jira dhowr nooc oo kala duwan oo soo noqnoqda;celiyaha telifoonku waa cod-weyneeye ku jira khadka taleefanka, dib-u-eegga indhaha waa wareegga indhaha ee kor u qaada iftiinka iftiinka ee fiilada fiber-ka;iyo ku celiyaha raadiyaha waa aqbale raadiyaha iyo gudbiyaha oo dib u gudbiya signalka raadiyaha.Kingtone Repeaters
Nidaamka Kingtone waxaa loogu talagalay in lagu xalliyo dhibaatooyinka signalada mobilada ee daciifka ah, kaas oo aad uga jaban in lagu daro Saldhig cusub (BTS).Hawlgalka ugu weyn ee nidaamka RF Repeaters waa in laga helo signalka tamarta yar ee BTS iyada oo loo marayo gudbinta soo noqnoqda raadiyaha ka dibna u gudbiya signalka la xoojiyay meelaha daboolka shabakadu ku filnayn.Iyo calaamada mobilada sidoo kale waa la xoojiyay oo loo gudbiyaa BTS iyada oo loo sii marayo jihada ka soo horjeeda.Telefoon ku celiyaha
Tan waxa loo istcimaalaa in lagu kordhiyo kala duwanaanta calaamadaha talefanka ee khadka taleefanka.Inta badan waxaa loo adeegsadaa khadadka jirridda ee qaada wicitaanada fogfog.Xariiqda teleefoonka analooga ah ee ka kooban fiilooyinka lamaanaha ah, waxa uu ka kooban yahay cod-weyneeye wareeg ah oo ka samaysan transistor-ka kaas oo isticmaala awood ka imanaysa isha DC ee hadda jirta si ay u kordhiso awoodda beddelka signalka maqalka ee hadda taagan ee khadka.Maadaama uu telefoonku yahay habka isgaadhsiinta laba-geesoodka ah (laba jiho), labada siligu waxay wataan laba calaamadood oo maqal ah, mid ka mid ah jihada kasta.Markaa taleefoonnada soo noqnoqda waa inay laba geesood noqdaan, iyagoo kor u qaadaya calaamada labada dhinac iyadoon wax jawaab celin ah keenin, taas oo si weyn u adkeynaysa naqshadooda.Soo-celiyeyaasha taleefanku waxay ahaayeen nooca ugu horreeya ee soo-celinta waxayna ahaayeen qaar ka mid ah codsiyada ugu horreeya ee cod-weyneysiinta.Horumarinta telefoonada soo noqnoqda intii u dhaxaysay 1900 iyo 1915 waxay suurta galisay adeeg taleefoon oo fog.Si kastaba ha ahaatee inta badan fiilooyinka isgaarsiineed ayaa hadda ah fiilooyinka fiber optic kuwaas oo isticmaala muraayadaha indhaha (hoose).Ku celiyaha gacanta
Tani waa raadiyaha ku celiska ah ee kor loogu qaadayo soo dhaweynta taleefanka gacanta ee aag xaddidan.Qalabku wuxuu u shaqeeyaa sida saldhig yar oo gacanta ah, oo leh anteeno jihada si uu uga helo calaamada munaaradda gacanta ee kuugu dhow, cod-weyneeye, iyo anteeno maxalli ah si ay dib ugu faafiso calaamada taleefannada gacanta ee dhow.Inta badan waxaa lagu isticmaalaa dhismayaasha xafiisyada hoose ee magaalada.

Codsiyada soo celinta signalka mobilada ee DCS 1800Mha
Si loo balaadhiyo daboolka calaamada buuxinta aagga indha la'aanta ee calaamaduhu daciif yihiin
ama aan la heli karin.
Banaanka: Garoomada Diyaaradaha, Gobolada Dalxiiska, Koorasyada Golf-ka, Tunnel-ka, Warshadaha, Degmooyinka Macdanta, Tuulooyinka iwm.
Gudaha: Hoteelada, Xarumaha Bandhiga, Qaybaha Hoose, Wax iibsiga
Suuqyada, Xafiisyada, Baakadaha Baakadaha iwm.
Inta badan waxay khusaysaa kiiskan:
Soo-celinta waxay heli kartaa meel rakibaadda taasoo heli karta calaamadda BTS saafi ah heer ku filan oo xooggan maadaama heerka Rx ee goobta soo noqnoqda uu ka badan yahay -70dBm;
Oo buuxin kara shuruudaha go'doominta anteenada si looga fogaado is-hawlgalayaasha.
