Qaar badan oo ka mid ah akhristayaashayada ku nool meelaha miyiga ah ayaa la halgamaya calaamadaha telefoonka gacanta oo liita waxayna inta badan ka raadiyaan internetka xalalka sidaXoojinta signalka taleefanka gacantas. Si kastaba ha ahaatee, marka ay timaado doorashada xoojiye saxda ah ee xaaladaha kala duwan, warshado badan ma bixiyaan hagitaan cad. Maqaalkan, waxaanu ku siin doonaa hordhac fudud oo aad ku dooranayso aXoojinta signalka taleefanka gacanta ee meelaha miyiga ahoo sharax mabaadi'da aasaasiga ah ee sida qalabkani u shaqeeyo.
1. Waa maxay Taleefanka Gacanta ee Kor u qaada Calaamadaha? Waa maxay sababta qaar ka mid ah wax-soo-saareyaashu ay ugu yeeraan soo-celinta Fiber Optic-ga?
1.1 Waa maxay Booster-ka Taleefoonka Gacanta iyo sidee buu u shaqeeyaa?
A Xoojinta signalka taleefanka gacantawaa qalab loogu talagalay in lagu kordhiyo calaamadaha unugyada (signals cell), waana erey ballaadhan oo ay ku jiraan aaladaha ay ka midka yihiin kor u qaada calaamadaha mobilada, calaamadaha mobilada, iyo cod-weyneyaasha gacanta. Erayadani asal ahaan waxay tixraacayaan isla nooca aaladda: xoojiye signalka taleefanka gacanta. Caadi ahaan, xoojiyayaashan waxaa lagu isticmaalaa guryaha iyo kuwa yaryargoobaha ganacsiga ama warshadahailaa 3,000 mitir oo laba jibbaaran (qiyaastii 32,000 cagood oo laba jibbaaran). Waa badeecooyin keligood ah oo aan loogu talagelin gudbinta signalada fogaanta. Habaynta dhamaystiran, oo ay ku jiraan anteenooyinkooda iyo xoojiye calaamadaha, badanaa waxay isticmaalaan fiilooyinka coaxial sida jumpers ama feederiyeyaasha si ay u gudbiyaan signalka gacanta.
1.2 Waa maxay Fiber Optic Repeater iyo sidee buu u shaqeeyaa?
A fiber optic repeaterwaxaa loo fahmi karaa sida ku celiyaha signalka taleefanka gacanta ee darajada-xirfadeed ee loogu talagalay gudbinta fogaanta. Asal ahaan, qalabkan waxaa loo sameeyay si loo xalliyo luminta calaamadda weyn ee la xiriirta gudbinta fiilada coaxial ee fogaanta fog. Fiber optic-ka ku celiska ahi waxa uu kala saaraa darafyada soo dhaweynta iyo kor u qaadista taleefoonnada gacanta ee caadiga ah, iyada oo la isticmaalayo fiilooyinka fiber optic-ga halkii laga isticmaali lahaa fiilooyinka coaxial ee gudbinta. Tani waxay u oggolaaneysaa gudbinta fogaanta fog oo leh luminta calaamadda ugu yar. Sababo la xiriira hoos u dhaca gudbinta fiber optic-ga, calaamada waxaa lagu gudbin karaa ilaa 5 kiiloomitir (ilaa 3 mayl).
Fiber Optic Repeater-DAS
Nidaamka soo noqnoqda ee fiber optic-ga, dhammaadka helaya calaamadda unugga ee saldhigga saldhigga waxaa loo yaqaannaa unugga dhammaadka-dhamaadka ah, dhammaadka cod-weyneysiinta ee meesha loo socdona waxaa loo yaqaannaa unugga fog-dhamaadka. Mid ka mid ah cutubyada dhamaadka-dhamaadka ah ayaa ku xidhmi kara unugyo-dhammaadyo badan, unug kasta oo fog-na waxa uu ku xidhmi karaa anteenooyin badan si loo gaadho daboolida ishaarada unugga. Nidaamkan looma isticmaalo oo keliya meelaha miyiga ah ee sidoo kale waxaa laga isticmaalaa dhismayaasha ganacsiga ee magaalooyinka, halkaas oo inta badan loogu yeero Nidaamka Anteennada La Qaybiyo (DAS) ama Nidaamka Anteennada Active Qaybsan.
Soo Celinta Fiber Optic-ga Gacanta ee Deegaanka Miyiga
Nuxur ahaan, kor u qaada calaamadaha taleefanka gacanta,fiber optic repeaters, iyo DAS dhamaantood waxay higsanayaan in la gaaro yool isku mid ah: baabi'inta calaamada unugyada aagagga dhintay.
2. Goorma ayay tahay inaad isticmaashid kor u qaadka signalka taleefanka gacanta, goorma ayay tahay inaad ka doorato soo celinta Fiber Optic ee meelaha miyiga ah?
2.1 Iyada oo ku saleysan waayo-aragnimadayada, haddii aad leedahay isha isha ee unug xoog leh200 mitir (qiyaastii 650 cagood), Xoojinta signalka taleefanka gacanta ayaa noqon kara xal wax ku ool ah. Mar kasta oo fogaantu sii fogaato, waa inta ay sii xoogaysan tahay xoojiye u baahan yahay inuu ahaado. Waa inaad sidoo kale isticmaashaa fiilooyinka tayada wanaagsan iyo kuwa qaaliga ah si aad u yareyso luminta calaamadaha inta lagu jiro gudbinta.

2.2 Haddii isha isha unugu ka sarreyso 200 mitir, waxaan guud ahaan ku talineynaa in la isticmaalo dib-u-celinta fiber optic.

2.3 Calaamadaha Luminta ee Noocyada Kala duwan ee Xargaha
Halkan waxaa ah isbarbardhigga luminta calaamadaha iyo noocyada kala duwan ee fiilooyinka.

2600MHZ | 15dBm | 25dBm | 30dBm | 35dBm |
2.4 Calaamadaha Khasaaraha ee Xadhkaha Fiber Optic
Xadhkaha Fiber optic-ga guud ahaan waxay leeyihiin calaamada luminta qiyaastii 0.3 dBm kiiloomitirkiiba. Marka la barbardhigo fiilooyinka coaxial iyo jumpers, fiber optics ayaa faa'iido weyn u leh gudbinta calaamadaha.
2.5 Isticmaalka fiber optic-ga gudbinta fogaanta fog waxay leedahay faa'iidooyin dhowr ah:
2.5.1 Khasaare Hoose:Xadhkaha Fiber optic-ga waxay leeyihiin lumitaanka calaamadda aad uga hooseeya marka loo eego fiilooyinka coaxial, taasoo ka dhigaysa inay ku habboon yihiin gudbinta fogaanta.
2.5.2Bandballaadhkeeda sare:Fiber optics waxay bixiyaan xajmigoodu aad uga sarreeyo fiilooyinka dhaqanka, taas oo u oggolaanaysa in xog badan la gudbiyo.
2.5.3 Xasaanadda Faragelinta:Fiber optics uma nugul faragelinta elektromagnetic, taasoo ka dhigaysa inay si gaar ah faa'iido ugu yeeshaan deegaannada faragelinta badan leh.
2.5.4Amniga:Xadhkaha Fiber optic-ga waa ay adag tahay in la geliyo, iyagoo siinaya qaab gudbin oo ammaan ah marka loo eego calaamadaha korantada.
2.5.5 Iyadoo loo marayo nidaamyadan iyo qalabkan, calaamadaha gacanta waxaa lagu kala qaadi karaa si hufan masaafo dheer iyadoo la isticmaalayo fiber optics, buuxinta baahiyaha adag ee shabakadaha isgaarsiinta casriga ah.
