J2I series Mini Repeater Band Selective offer not only elegant versatile design of appearance but also contribute outstanding performance for indoor coverage problem solution.
The J2I series Mini Repeater Band Selective provides a perfect solution to satisfy operators demands for variable band selections of GSM, CDMA or 3G 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.
1.It is a traditional repeater with RF N female connectors, mostly used in indoor distribution system to be connected wiht more than one antenna for optimal coverage.
2.They have below recommended coverage sizes:1) J2I-10: 100~200 squae meters. 2). J2I-13: 300~500 Sqm. 3). J2I-17: 500~1000 Sqm.
3.Intermediate SAW filter technology for very sharp out of band rejection to amplify only specific operators’s signals and reject all the others.
3.Manual gain control (MGC) available for both uplink and downlink to adjust the gain value for proper coverage during installation or maintance.
4.To maintain safe and specific output signal levels and give alarms on self-oscillation, the repeater has built-in AGC and ALC circuits, which can automatically control the gain of the repeater depending upon the strength of input signals.
5.Auto shut off design available for both uplink and downlink to avoid serious interference to network effectively when the repeater is in deep self-oscillation of very strong input power.
8.The repeater can be locally and remotely monitored and controlled through its integrated software circuit, remote control software of both local NMS and NMS in Server. NMS can be connected with its upper level software throught SNMP. (Optional).
