43dBm WCDMA 2100MHz Outdoor Ics Repeater
Model: VR-4395-W
Product Instructions
Product Features
Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corrodingReal Time interference signal cancellation (Multi-path Fading, Feed-Back signal) greatly reduces system isolation requirementNo interference to BTS by adopting linear amplifier with high gain and low noiseAdopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlinkRS-232 port provides a link to a notebook for local supervision or to the built-in wireless modem to communicate with the NMS (Network Management System) that can remotely supervise repeater's working status and download operational parameters to the repeater.
Applications
To expand signal coverage or fill signal blind area where GSM and
WCDMA signal is weak or unavailable.
Outdoor: Airports, tourism regions, golf courses, tunnels,
factories, mining districts, villages,
Indoor: Hotels, exhibition centers, basements, shopping malls,
offices, parking lots, etc.
