AJB-*** tri-band SMART repeater 22dBm


JB-** serie SMART TRI-Band Selective Repeater 

Repeater offers perfect design of appearance and contributes outstanding performance for indoor coverage problem solution.

 

The repeater is working as a relay between the BTS and mobiles. It picks up the strongest signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Indoor Signal Distribution System to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.

Tri-band repeater amplifies and retransmits the signal of three different bands: for example EGSM and UMTS2100.

 

The Band Selective Repeater provides an affordable solution for operator to solve the indoor signal coverage problems due to signal fading and attenuation caused by architecture obstacles. And its easy installation and maintenance can help carrier get fast return. Band selective with Out of Band Gain function will simply enable less noise or suppress interference from operators frequency band.

Both bands of dual band selective repeater are filtered by particular operator bandwidth. Other operators signals are  rejected.

 

SMART repeater adopted the most cutting-edge technology and realized the smart man-machine conversation. As result even the end user could install by the LCD screens reminding step by step and maintain the repeater without any help.

   

Three independent systems embedded

 

GSM, CDMA, 3G or 4G system and various bandwidths are available as well.

 

Work Frequency bands

(three fixed bands) :

  • LTE800
  • GSM900 & EGSM
  • DCS1800 (LTE1800)
  • WCDMA2100 (LTE2100)
  • LTE2600
  • and so on.  
Function   
  • Uplink noise elimination. Does not interference base station absolutely.
  • Automatic  dormancy when no user make the calling. Once detected the the user make the calling, repeater wakes up to working status immediately.
  • Two LCD screens display input / output real signals strength.
  • Automatic shut down the power supply of the screen when no operation on it.
  • Automatic to adjust the system gain. High Automatic Gain Control (AGC) adjustment range up to 55dB.
  • High speed digital Automatic Level Control (ALC) system
  • Metal housing, good heatlink, profesionally looking, high gain, low power loss.

 SMART function:

  • Full smart processor to display all the parameters of three systems automaticly detects the faults of the device and provide the corresponding solution.
  • Two super intelligent LCD displays guide of installation provides the easiest and simplest installation solution of three bands. Second display is switching between two band monitoring.  
  • Smart man-machine conversation, could be installed and maintained without any help.
  • Uplink automatic shut off when device detected self-excitation.
  • Automatic detect the distance between receive antenna and relay antenna, avoid device autoexcitation. After turning on repeater tests whether the isolation between donor antenna and service antenna meet up the repeater working condition. If repeater self testing find that donor antenna and service antenna isolation does not meet the requirements, repeater come up alarm and set both uplink and downlink gain so as to meet the requirements of donor antenna and service antennas isolation. Isolation value and gain are displaying in the LCD screens.
 

Band selective feature (fixed from the factory): 

  • Any three bands can be choosed.
  • Operator can order repeater with two fixed bandwidth and fixed frequencies.
  • Cost effective. Operator saves much of expenses in comparison with compettive tri-band selective solutions.
