DSP 37dBm Dual Band Wifi Extender 1800MHz WCDMA Digital Repeater
Digital Repeater is a new kind of RF Repeater that is adopting DSP (Digital Signal Processing) technology basis on FPGA platform, highly linear components and unparalleled innovative DSP filtering provide top level performance. Digital Repeater can be selected as Band Selective or Channel Selective operation mode, which supports up to 12 channels both on uplink and downlink. Using an advanced ALC mechanism, each one of the channels has an individual gain and ALC setting.
Digital Repeater Features:
· Aluminum-alloy IP65 casing has high resistance to dust, water and corroding;
· High gain linear power amplifier technique with reliable performance
· In-built AGC & ALC function be able to ensure easy installation without setting.
· Compact size and light weight, easy to install on wall or pole
· Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink
· Support SNMP and Web-based GUI.
· RS232 or RJ45 ports provide links to laptop for local setting and monitoring by built-in web interface.
· Built-in wireless modem (Option) for remote monitoring by SMS, GPRS or TCP/IP.
· Details repeater parameters and status can be monitoring by built-in web interface, such as RSSI, temperature, output power level, gain, ATT, return loss, VSWR etc.
Digital Repeater Application:
To expand signal coverage or fill signal blind area where signal is weak or unavailable.
· Outdoor: Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages, highways
· Indoor: Hotels, exhibition centers, basements, shopping malls, offices, parking lots.
