IkhathalogiI-RF POI imeleIphuzu le-RF le-Interface, okuyidivayisi yokuxhumana ngocingo ehlanganisa futhi isabalalise izimpawu eziningi zemvamisa yomsakazo (RF) ezivela kubasebenzi benethiwekhi noma izinhlelo ezahlukene ngaphandle kokuphazamiseka. Isebenza ngokuhlunga nokuhlanganisa izimpawu ezivela emithonjeni ehlukahlukene, njengeziteshi eziyisisekelo zabasebenzi abahlukene, zibe yisignali eyodwa, ehlanganisiwe yesistimu yokumboza yangaphakathi. Inhloso yayo ukuvumela amanethiwekhi ahlukene ukuthi abelane ngengqalasizinda efanayo yangaphakathi, ukunciphisa izindleko kanye nobunzima ngenkathi kuqinisekiswa ukulethwa kwesignali okuthembekile kwezinsizakalo eziningi ezifana nokuxhumana kweselula, i-LTE, kanye nokuxhumana okuyimfihlo.
Indlela esebenza ngayo
• I-Uplink: Iqoqa amasignali avela kumaselula ngaphakathi kwendawo bese iwathumela eziteshini eziyisisekelo ezifanele ngemuva kokuwahlunga nokuwahlukanisa ngemvamisa kanye nomqhubi.
• I-Downlink: Ihlanganisa amasignali avela kubasebenzi abaningi kanye nama-frequency band bese iwahlanganisa abe yisignali eyodwa ezosatshalaliswa kulo lonke isakhiwo noma indawo.
• Ukuvimbela ukuphazamiseka: I-POI isebenzisa izihlungi ezithuthukisiwe kanye nezihlanganisi ukuhlukanisa nokuphatha amasignali, ukuvimbela ukuphazamiseka phakathi kwamanethiwekhi ahlukene opharetha.
Iyunithi ye-RF POI ingafaka:
| Ingxenye | Inhloso |
| Izihlungi / Ama-Duplexer | Izindlela ezihlukene ze-UL/DL noma amabhendi emvamisa ahlukene |
| Ama-Attenuator | Lungisa amazinga wamandla ukuze kube nokulingana |
| Ama-circulator/Isolators | Vimbela ukubonakaliswa kwesignali |
| Abahlukanisi Bamandla/Abahlanganisi | Hlanganisa noma hlukanisa izindlela zesignali |
| Ama-Couplers Aqondisayo | Gada amazinga esignali noma phatha umzila |
I-RF POI yaziwa kakhulu ngamanye amagama amaningana kuye ngesifunda kanye nokusetshenziswa. Amagama ahlukile avame kakhulu afaka:
| Ithemu | Igama eligcwele | Incazelo / Umongo Wokusetshenziswa |
| Iyunithi Yesixhumi Esibonakalayo se-RF | (RF IU) | Igama elijwayelekile leyunithi exhumanisa imithombo eminingi ye-RF ne-DAS. |
| Isihlanganisi Sezisebenzisi Eziningi | I-MOC | Kugcizelela ukuhlanganisa abathwali/abaqhubi abaningi. |
| Isihlanganisi Sezinhlelo Eziningi | I-MSC | Umqondo ofanayo, usetshenziswa lapho ukuphepha komphakathi + amanethiwekhi ezentengiselwano ehlala khona ndawonye. |
| Iphaneli Yesikhombimsebenzisi se-MCPA | I-MCPA = Isikhulisi Samandla Esithwala Amandla Amaningi | Kusetshenziswa ezinhlelweni ezixhuma ku-MCPA noma ku-BTS. |
| Isihlanganisi Sekhanda | — | Kusetshenziswa emakamelweni e-DAS ngaphambi kokusatshalaliswa kwesiginali. |
| Isihlanganisi se-POI | — | Ukwehluka okulula kokuqamba amagama ngqo. |
| Iphaneli Yesiginali Yokuxhumana | I-SIP | Ukuqanjwa kwe-telecom okujwayelekile, ngezinye izikhathi kusetshenziswa ku-DAS yokuphepha komphakathi. |
Njengomkhiqizi ochwepheshe weIzingxenye ze-RFI-Apex ayigcini nje ngokuhlinzeka ngezingxenye ngazinye zezinhlelo zokusebenza ezahlukene, kodwa futhi iklama futhi ihlanganise i-RF POI njengemfuneko yamakhasimende. Ngakho-ke uma udinga olunye ulwazi, wamukelekile ukuxhumana nathi.
