Kingtone JIMTOM® Fiber Optic Repeaters eto jẹ apẹrẹ lati yanju awọn iṣoro ti ifihan agbara alagbeka alailagbara, eyiti o din owo pupọ ju iṣeto Ibusọ Base tuntun (BTS).Iṣe akọkọ ti eto RF Repeaters: Fun ọna asopọ isalẹ, awọn ifihan agbara lati BTS jẹ ifunni si Ẹka Titunto (MU), MU lẹhinna yi ifihan RF pada si ifihan laser lẹhinna ifunni si okun lati tan kaakiri si Ẹka Latọna jijin (RU).RU lẹhinna yi ifihan agbara laser pada si ifihan agbara RF, ati lo Ampilifaya Agbara lati pọ si agbara giga si IBS tabi eriali agbegbe.Fun ọna asopọ oke, Ṣe ilana iyipada, awọn ifihan agbara lati alagbeka olumulo jẹ ifunni si ibudo MS MU.Nipasẹ duplexer, ifihan agbara ti pọ nipasẹ ampilifaya ariwo kekere lati mu agbara ifihan dara si.Lẹhinna awọn ifihan agbara jẹ ifunni si module opitika fiber RF lẹhinna yipada si awọn ifihan agbara laser, lẹhinna ifihan agbara laser ti gbejade si MU, ifihan agbara laser lati RU yipada si ifihan RF nipasẹ transceiver opiti RF.Lẹhinna awọn ifihan agbara RF ti pọ si awọn ifihan agbara diẹ sii ti a jẹ si BTS.
RF Repeater jẹ apẹrẹ lati jẹki agbegbe nẹtiwọọki cellular ati kun awọn aaye afọju.Iṣe akọkọ ti oluṣe atunṣe ni lati gba ifihan agbara kekere lati Ibusọ Base (BS) nipasẹ gbigbe igbohunsafẹfẹ redio (RF) nipasẹ eriali oluranlọwọ rẹ, ilana, imudara ati firanṣẹ ifihan agbara si Ibusọ Alagbeka (MS) ni agbegbe agbegbe ibi-afẹde nipasẹ iṣẹ rẹ eriali.
Akọkọ Awọn ẹya ara ẹrọ
- FPGA Base SDR ọna ẹrọ, Dinku jade ti iye ere ijusile;
- Ti abẹnu gba ibojuwo oye, rọrun lati wa awọn aṣiṣe fun itọju;
- Lilo agbara kekere, itusilẹ ooru to dara julọ;
- Laini giga PA, ere eto giga;
- Abojuto agbegbe ati latọna jijin (iyan) pẹlu itaniji aṣiṣe aifọwọyi & iṣakoso latọna jijin;
- Iwapọ iwọn, rọ fun fifi sori ati sibugbe;
- Apẹrẹ oju ojo fun fifi sori oju ojo gbogbo;
- Ọkan MU le wakọ Max 32 RUs, Fipamọ idiyele ati irọrun fifi sori ẹrọ.
- Oruka atilẹyin, pq daisy, topology star, mu irọrun nẹtiwọọki pọ si.
- Apẹrẹ pupọ ti ngbe, awọn gbigbe 16 max, Ni irọrun mu awọn oju iṣẹlẹ ohun elo ijabọ giga
