Detailed Product Description
Tri-Band CDMA/GSM&DCS&WCDMA In-Line
Repeater/ Trunk Amplifier
Model: KR-4345CDW/ KR4345-GDW
Introductions:
The Tri-band
CDMA800/GSM900&DCS1800&WCDMA In-Line Repeater/ Trunk Amplifier provides an affordable solution to solve the
indoor signal coverage problems in both CDMA800/ GSM900&DCS1800&WCDMA
system due to signal fading and attenuation caused by architecture obstacles.
And its easy installation and maintenance can help carrier get fast return.
Features:
Support
DCS &WCDMA &CDMA/GSM system;
Using
the common RF cables to guarantee the even distribution of indoor signals and
minimize the construction influence and user investment;
Multiple
data transmission modes (RS-485, PSTN, GSM Modem, etc.), perfect system
monitoring functions;
Centrally-controlled
system monitoring function available; providing one interface for the
monitoring of all equipment in the entire distribution system
Applications
To expand signal coverage or fill signal
blind area where signal is weak or unavailable.
Indoor:
Hotels, exhibition centers, basements, shopping malls, offices, parking lots, etc.
