RF POI u taagan tahayBarta Interface ee RF, kaas oo ah qalab isgaarsiineed oo isku dara oo qaybiya calaamado badan oo soo noqnoqda raadiyaha (RF) ee ka shaqeeya shabakadaha kala duwan iyada oo aan la faragelin. Waxay u shaqeysaa iyadoo shaandheynaysa oo isku dubaridisa calaamadaha ilo kala duwan, sida saldhigyada hawl-wadeennada kala duwan, hal, calaamad isku dhafan oo loogu talagalay nidaamka daboolka gudaha. Ujeeddadeedu waa in ay awood u siiso shabakadaha kala duwan si ay u wadaagaan isla kaabayaasha gudaha, yaraynta kharashyada iyo kakanaanta iyada oo la hubinayo gaarsiinta calaamadaha la isku halayn karo ee adeegyo badan sida gacanta, LTE, iyo isgaarsiinta gaarka ah.
Sida ay u shaqeyso
• Uplink: Waxay ka ururisaa calaamadaha taleefoonnada gacanta ee aagga waxayna u dirtaa saldhigyada saldhigyada ka dib marka ay shaandhayso oo ay ku kala soocdo inta jeer iyo hawlwadeen.
• Downlink: Waxa ay soo saartaa calaamadaha hawlwadeeno badan iyo xargaha soo noqnoqda oo isku daraa hal calaamad oo loo qaybiyo dhismaha ama aagga oo dhan.
Kahortagga faragelinta: POI waxay isticmaashaa filtarrada horumarsan iyo isku-dariyeyaasha si ay u kala saaraan una maamulaan calaamadaha, iyagoo ka hortagaya faragelinta shabakadaha kala duwan ee hawlwadeennada.
Unugga RF POI waxa ku jiri kara:
| Qayb | Ujeedo |
| Filters / Duplexers | Kala saar dariiqyada UL/DL ama xargaha soo noqnoqda ee kala duwan |
| Attenuators | Hagaajin heerarka awoodda sinaanta |
| Wareegtada / Go'doominta | Ka hortag milicsiga calaamadaha |
| Qaybiyeyaasha Awoodda / Isku-dhafka | Isku-dar ama kala qaybso dariiqyada calaamadaha |
| Lammaanayaasha Jihooyinka | La soco heerarka signalka ama maamul dajinta |
RF POI waxaa badanaa loo yaqaan dhowr magac oo kale iyadoo ku xiran gobolka iyo codsiga. Magacyada beddelka ah ee ugu caansan waxaa ka mid ah:
| Muddada | Magaca oo buuxa | Macnaha / Isticmaalka Macnaha |
| RF Interface Unit | (RF IU) | Magaca guud ee cutubka isku xidha ilo badan oo RF ah oo leh DAS. |
| Isku-duwaha Multi-Operer | MOC | Waxay xooga saaraysaa isku darka sidayaal/shaqaaleyaal badan. |
| Isku-xidhaha Nidaamyada Badan | MSC | Fikrad la mid ah, oo loo isticmaalo halka badbaadada dadweynaha + shabakadaha ganacsiga ay ku wada nool yihiin. |
| MCPA Interface Panel | MCPA = Cod-weyneeye Koronto Qaade Badan | Loo isticmaalo nidaamyada ku xidha MCPA ama BTS. |
| Isku-dhafka Madaxa-dhamaadka | - | Loo isticmaalo qolalka madaxa-dhamaadka DAS ka hor qaybinta calaamadaha. |
| Isku-duwaha POI | - | Kala duwanaansho magaceed toos ah oo fudud. |
| Gudida Interface Signal | SIP | Magacaabid isgaarsiineed oo aad u badan, oo mararka qaarkood loo isticmaalo badbaadada dadweynaha DAS. |
Sida soo saaraha xirfadeed eeQaybaha RF, Apex kaliya ma bixiso qaybaha gaarka ah ee codsiyada kala duwan, laakiin sidoo kale waxay naqshadeeyaan oo isku daraan RF POI sida shuruudaha macaamiisha. Markaa haddii aad u baahan tahay macluumaad dheeraad ah, waa lagugu soo dhawaynayaa inaad nala soo xidhiidho.
