20dBm EGSM900 Industrial Repeater Cell Phone Signal Boosters
with Adjustable Central Frequency
Cell Phone Signal Booster Description:
The bandwidth central frequency is adjustable via SW setup. The installation of the repeater is easy and simple with its plug and play design and operational user friendliness. Via as small Microsoft compatible application the repeater is easy to configure. It has a smart function which can be activated via the front panel. This smart function can prevent UL interference and self -oscillation caused by insufficient isolation between donor and server antennas, and also setup parameters and keep optimal condition automatically. Activate this function by the front panel of this repeater.
20dBm Adjustable 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 LCD 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.
Cell Phone 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
