China 23dBm 900MHz&1800MHz&2600MHz Tri BSignal Booster GSM Repeater Extender

23dBm 900MHz&1800MHz&2600MHz Tri Band Signal Booster /GSM Repeater / router extender(GW-23R-GDL)
Model: GW-23R-GDL
Tri-Band Signal Booster series is an ideal solution for three wireless system in small/medium businesses and home users looking to enhance indoor 2G&3G wireless connectivity. It is connected via coaxial cable to Tri-Band Donor Antenna and Service Antenna, Tri-Band Donor Antenna is placed outside the building where it has easy access to BTS signal, and the Service Antenna is placed in the building where it can extend radio coverage to the blind area.
Advantages:

The installation of a repeater is easy and simple. With its plug and play design, installation simplicity, and operational user friendliness, these features appeal greatly to many operators for the purpose of indoor coverage or for temporary coverage during network optimization.

Compare to the worldwide repeater brand, has a smart function called 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 service antennas, and also setup parameters and keep optimal condition automatically; the only thing for users is just activating this function by front panel.

For example,(To set attenuation for the uplink)
Step 1:Press SELECt till the indicator stops at uplink.
Step 2:Press STORE and LED monitor starts blinking.
Step 3:Press"+", "-"to an intended gain value.
Step 4:Press STORE to set the value and the LED stop blinking and
showing the gain value at the moment, the process is done.
The 20dB ALC is used to maintain steady output power even when the donor source signal fluctuates. Also when the ALC is activated, the ISOLATION LED indicator would be lighted in orange, which means the Isolation may not be enough. .It also prevents UL interference and self-oscillation from insufficient isolation between donor and service antennas.
Repeater uplink is not used when the device will automatically close up PA. Open the -90dBm uplink signal sensitivity. The upstream silent function can make the repeater station to base station interference is reduced to the minimum, to ensure that equipment is not interference base station. This function customer can also use the equipment operation buttons on the panel to open or close the function, facilitate customer choice.
The product also has a repeater mounted antenna isolation detection function. Equipment installation completed boot automatically after the onset detection transceiver antenna isolation, if transceiver antenna isolation can not meet the installation requirements, the device will automatically reduce the gain to guarantee the equipment in normal working, not self-excitation vibration, guarantee not to interference protection of base station, repeater itself. At the same time alarm exhibit of lanterns bright red light alarm. Device LED gain display panel will display device is reduced after the equipment current gain state, which has the advantages of convenient construction, but also to protect the base station equipment, and does not generate interference.

Application:
To expand signal coverage of fill signal blind area where signal is weak or unavailable.
Indoor: Hotels, Home, basements, Shopping Malls, Offices, Parking Lots, Shop.etc.
