Waa maxay sababta Fiber Optic Repeater?
Kingtone Fiber Optic Repeaters nidaamka waxaa loogu talagalay in lagu xalliyo dhibaatooyinka signalada mobilada daciifka ah, kaas oo aad uga jaban marka loo eego dejinta Saldhig cusub (BTS).Hawlgalka ugu weyn ee nidaamka RF Repeaters: Isku xirka hoose, calaamadaha BTS waxaa lagu quudiyaa Master Unit (MU), MU ka dib waxay u beddelaan calaamadda RF si ay u noqdaan calaamadda laser ka dibna waxay ku quudiyaan fiber si ay ugu gudbiyaan Unit Fog (RU).RU ayaa markaa u beddela signalka laysarka calaamada RF, oo isticmaal Power Amplifier si aad ugu xoojiso awooda sare ee IBS ama anteenada caymiska.Isku xirka kor, Waa habsocod rogan, calaamadaha mobilka isticmaalaha waxaa lagu quudiyaa MU's dekedda MS.Iyada oo loo marayo duplexer, signalka waxaa lagu kordhiyey cod-weyneeye dhawaqa sanqadha si loo hagaajiyo xoogga calaamada.Kadibna calaamadaha waxaa lagu quudiyaa RF fiber optical module ka dibna loo beddelaa calaamadaha laserka, ka dibna calaamadda laysarka ayaa loo gudbiyaa MU, calaamadda laser-ka ee RU ayaa loo beddelaa signalka RF ee RF indhaha.Kadibna calaamadaha RF waxaa lagu kordhiyey calaamado xoog badan oo lagu quudiyo BTS.
Astaamaha:
- Fiber Optic RF Repeater waa xal la isku halayn karo si loo kordhiyo loona wanaajiyo aagga daboolka shabakada TETRA 400MHz
- Waxay ka kooban tahay laba qaybood oo waaweyn, Master iyo unugyo addoomo badan.
- 33, 37, 40 ama 43dBm awood wax soo saarka isku dhafan, oo buuxiya heerarka nidaamyada
- Ku rakibida goobta fudud iyo dayactirku waxay yaraynaysaa soo-bandhigidda iyo kharashyada hawlgalka
- Gudbinta ishaarada ee ku celiyaha fiber optic ma dhibayso saamaynta dibadda
- Bixi adeegga caymiska RF ee degdegga ah saldhiggaaga Saldhigga TETRA
- Cabbirka Is haysta iyo Waxqabadka Sare ee xayndaab aan biyuhu lahayn oo ku habboon rakibaadyada dibadda iyo gudaha
