J3-20* single band inteligent repeater 20dBm power


Overview:
J3-20* series Repeater Band Selective offer not only elegant versatile design of appearance but also contribute outstanding performance for indoor coverage problem solution. It amplifies signals between a mobile and a BTS for indoor applications where are located in shadowing areas blocked by obstructions or impediments.
 
This series Repeater Band Selective provides a perfect solution to satisfy operators demands for variable band selections of GSM, CDMA, 3G or 4G system and various bandwidths are available as well.
Band selective with Out of Band Gain function will simply enable less noise or suppress interference from operators frequency band.
 
System status is clearly visible by LED indications. Repeater configuration and alarm are able to be forwarded to control center for technicians monitoring via OMT / OMC software. With remote monitoring optional feature repeater has embedded modem and battery, so control center will get messages even if electrical network is broken.
 
The light weight and compact size makes this series repeater ideal for friendly installation with little space.
 Repeater fully and completelly complies CE directives.
  
 
Work Frequency band (one band) :
  • LTE800
  • GSM900 & EGSM
  • DCS1800
  • WCDMA2100
  • LTE2600
  • and so on.  
Band selective feature (upon request): 
  • Any single band can be choosed.
  • Operator can order repeater with any fixed bandwidth 0.2 - 40MHz even more.
  • Movable central frequency feature (optional) is ordering upon request. Bandwidth fixed. Installer can move frequency, but can't change badwith. 
  • Adjustable bandwith feature (optional) is ordering upon request. Operator's installer can move frequency and change bandwith.
  • OMT software let's change bandwidth and frequency remotelly if adjustable bandwidth or movable frequency feature is ordered. Repeater must to have embedded wireless modem (optional).
 
Intelligent mode : 
Purpose: after turning on Repeater, you can test whether the isolation between donor antenna and service antenna meet up the repeater working condition. When donor antenna and service antenna isolation does not meet the needs, the repeater will automatic alarm, auto start protection features, at the same time reduce the gain, to meet the current antenna isolation value gain donor antenna and service antenna isolation to meet the repeater work properly.
Donor antenna and service antenna isolation (ISO) ≧ the repeater maximum gain +15dB.
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.
Alarm LED light on within 1 minute after the repeater turn on, it means antenna isolation alarm.
If Alarm LED light on 1 minute after the repeater turn on, it means the repeater receiving  very strong signal from the base station.
