23dBm 2G 3G 4G Lte Band 12 Band 4 Band 7 Tri Band Signal Booster

Model: GW-23LAL

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&4G 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.





Features:
1. Cost effective solution for weak signal zones, reduce drop/off calls.
2. Compact size, low power consumption, easy installation, great cover.
Expansion and extention of the signal of base station. Optimization of the quality of the signal and source
3. Cover about 500~3000m² Without block or obstruct.
4. High linear design, ALC function design, low interference to BTS.
5. Support any cellular devices (voice & data & video)
6. Wide band signal booster, or customize selective band booster.
7. Support System CDMA800, GSM, DCS, PCS, WCDMA, UMTS,LTE 4G etc

Recommended Accessories:
1)Donor antenna: Log Periodic Antenna (9dBi, 806-960/1710-2700MHz)
2)Service antenna: Omni Ceiling Antenna (3dBi, 806-960/1710-2700MHz)
3)5D-FB coaxial cable with connecter (Cable length optional)

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.

      Q1. Why is there still no signal after installing the equipment?

            1. Check the power on booster and power supply.

            2. Check the connector of outdoor antenna is tight or not.

            3. Check the connectors of RF cable are tight or not.

            4. Check the outdoor signal is strong enough or not.

            5. Check to make sure the antenna is installed correctly.

            6. Check the connector of indoor antenna is tight or not.

            7. Check the cable type is suitable or not.

 

      Q2. Why the signal strength is too weak on the edge of area?

            1. Check the outdoor signal and antenna direction.

            2. Check booster is full gain or not.

            3. Check all of the connectors are tight.

            4. Change the location of outdoor/indoor antenna.

            5. Check the cable type is suitable or not.

            6. Deploy more indoor antennas.

 

      Q3. After running booster, why the signals are not stable?

            1. Checking the distance between donor antenna and server antenna are too close to each other? Check LED

                of booster to make sure alarms are green.

            2. Checking the signals from donor antenna whether to be stable or not?

            3. Connect the system again if it is incorrect connection.

 

      Q4. Why the booster power LED is not bright?

            1. Checking the input AC power range indicated on power adapter whether is corresponding to the local

                power system.

            2. Checking the power adapter whether connect the equipment correctly and stably or not.

            3. Checking the power adapter whether damage or not. To test output voltage whether be corresponding to

                that indicated on power adapter or not by multimeter
