Detailed Product Description
Dual-Band CDMA/GSM/DCS&WCDMA
In-Line Repeater/ Trunk Amplifier
Model: KR-4345CW/ KR-4345CW/ KR-4345DW
Introductions:
The Dual-Band
CDMA800/GSM900/DCS1800&WCDMA In-Line Repeater/ Trunk Amplifier provides an
affordable solution to solve the indoor signal coverage problems in both DCS1800&WCDMA
system due to signal fading and attenuation caused by architecture obstacles.
Features:
Support
CDMA/GSM/DCS &WCDMA 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.
