I-RF POI imeleI-RF Point of Interface, okuyidivayisi yezokuxhumana ehlanganisa futhi isabalalise amasignali efrikhwensi yomsakazo amaningi (RF) avela opharetha benethiwekhi abahlukene noma amasistimu ngaphandle kokuphazanyiswa. Isebenza ngokuhlunga futhi ihlanganise amasiginali avela emithonjeni ehlukahlukene, njengeziteshi eziyisisekelo zabasebenzisi abahlukene, ibe isignali eyodwa, ehlanganisiwe yesistimu yokumboza yasendlini. Inhloso yawo ukunika amandla amanethiwekhi ahlukene ukuthi abelane nengqalasizinda efanayo yasendlini, ukunciphisa izindleko nokuba yinkimbinkimbi ngenkathi kuqinisekiswa ukulethwa kwesignali okuthembekile kumasevisi amaningi afana neselula, i-LTE, nokuxhumana kwangasese kwe-trunking.
Isebenza kanjani
• I-Uplink: Iqoqa amasignali kumakhalekhukhwini endaweni futhi iwathumele eziteshini ezilandelanayo eziyisisekelo ngemva kokuhlunga nokuwahlukanisa ngamafrikhwensi kanye no-opharetha.
• I-Downlink: Ihlanganisa amasignali avela ku-opharetha abaningi namabhendi efrikhwensi futhi iwahlanganise abe isignali eyodwa ezosatshalaliswa kusakhiwo sonke noma indawo.
• Ukuvimbela ukuphazamiseka: I-POI isebenzisa izihlungi nezihlanganisi ezithuthukisiwe ukuze ihlukanise futhi ilawule amasignali, ivimbela ukuphazamiseka phakathi kwamanethiwekhi o-opharetha abahlukene.
Iyunithi ye-RF POI ingafaka:
| Isakhi | Inhloso |
| Izihlungi / Duplexers | Hlukanisa izindlela ze-UL/DL noma amabhendi amafrikhwensi ahlukene |
| Abaqaphi | Lungisa amazinga amandla ngokulingana |
| Amasekhethi / Ama-Isolators | Vimbela ukubonakaliswa kwesignali |
| Izihlukanisi zamandla / Izihlanganisi | Hlanganisa noma uhlukanise izindlela zesignali |
| Abashadile abaqondisayo | Gada amaleveli esignali noma phatha umzila |
I-RF POI yaziwa kakhulu ngamanye amagama amaningana kuya ngesifunda kanye nesicelo. Amagama ahlukile ajwayelekile ahlanganisa:
| Ithemu | Igama eligcwele | Incazelo / Ukusetshenziswa Kokuqukethwe |
| Iyunithi ye-RF Interface | (RF IU) | Igama elijwayelekile leyunithi exhumanisa imithombo ye-RF eminingi ne-DAS. |
| I-Multi-Operator Combiner | I-MOC | Igcizelela ukuhlanganisa abathwali abaningi/ama-opharetha. |
| I-Multi-System Combiner | I-MSC | Umbono ofanayo, osetshenziswa lapho ukuphepha komphakathi + amanethiwekhi ezentengiselwano ehlala ndawonye. |
| MCPA Interface Panel | I-MCPA = Isikhulisamandla Samandla Enkampani Eningi | Isetshenziswa kumasistimu axhumeka ku-MCPA noma i-BTS. |
| I-Head-End Combiner | - | Isetshenziswa emakamelweni aphezulu e-DAS ngaphambi kokusatshalaliswa kwesignali. |
| I-POI Combiner | - | Ukwehluka kwamagama okuqondile okulula. |
| Iphaneli Yesixhumi Esibonakalayo | SIP | Ukuqamba kwe-telecom okujwayelekile, kwesinye isikhathi okusetshenziswa ekuphepheni komphakathi kwe-DAS. |
Njengomkhiqizi ochwepheshe weIzingxenye ze-RF, I-Apex ayinikezi kuphela izingxenye ezithile zezinhlelo zokusebenza ezahlukene, kodwa futhi iklama futhi ihlanganise i-RF POI njengemfuneko yamakhasimende. Ngakho uma udinga olunye ulwazi, wamukelekile ukuxhumana nathi.
