Adjustable Central Frequency Cell Phone Signal Boosters for Tri Band EGSM DCS WCDMA
Signal Booster Description:
Tri band Adjustable repeater is designed for installations in offices, warehouses, factories, shopping malls and business centers. It is easy to install, offers high call quality, high gain, a simple prompt software setup makes installation of this repeater an east easy plug and play task. With the control panel in front of the repeater, the repeater status can be known during installation. This repeater is an advanced repeater system that automatically cancels the feedback interference between the service and donor antennas by using the digital signal processing technology.
20dBm Tri Band Movable Repeater allow small to medium size indoor areas have reliable radio communications for first responders. Automatic gain control allows stable output power even when the handheld is close to the repeater, which protects the donor site from interruption. The unit is housed by a compact and light alumina casting enclosure.
The built-in external LED accessible from the bottom of the enclosure allow the uplink and down link gains, Output Powers, Alarms and so on be configured and optimized easily on site without additional tool. Signal strength indicator helps find donor signal source and set up the system in the field without additional equipment.
Signal Booster Features:
1. Uplink/downlink frequency full range, or custom bands
2. Built-in Saw filter provides high out of band rejection
3. Built-in switches and signal strength indicator allow find donor
signal source and set up the system on site
without additional equipment
4. External 100-240V AC universal power supply
5. Indoor wall mount
6. Heatsink convection cooling and low power consumption
7. Built-in ALC provides stable output power even when the handheld
is close to the repeater to minimize the
interference to the donor site
