3. Pre-Installation: Checking Your Frequency Band

Before installation, it is crucial to verify that your mobile network operates on Band 1 (2100 MHz), Band 3 (1800 MHz), or Band 8 (900 MHz). This booster is specifically designed for these frequencies. You can check your phone's frequency band using the methods below:

3.1 For iPhone Users

Dial *3001#12345#* and press the call button. Navigate to 'Serving Cell Info' or 'LTE' to find the frequency band information.

3.2 For Android Users

Download an application like 'Network Cell Info Lite' from your app store. Use the app to guide you through checking the band number.

Important: Ensure your outdoor signal strength is at least 1-2 bars for the booster to function effectively. The booster amplifies an existing signal; it does not create one.

4. Installation Guide

Follow these steps for optimal installation. The process involves receiving the outdoor signal, enhancing it with the booster, and releasing the amplified signal indoors.

4.1 Step 1: Outdoor Antenna Placement (Receiving Signal)

• Mount the outdoor antenna in a location with the strongest possible signal. This is typically on a rooftop, pole, or exterior wall, facing the nearest cell tower.
• Ensure the outdoor antenna is positioned as high as possible and free from obstructions.
• Connect the 15m outdoor coaxial cable to the outdoor antenna.

4.2 Step 2: Booster Unit Placement and Connection (Enhancement)

• Install the booster unit indoors, in a central location where you need improved signal.
• Connect the other end of the 15m outdoor coaxial cable to the 'BTS' port on the booster unit.
• Ensure there is adequate separation (at least 10 meters vertically and horizontally) between the outdoor and indoor antennas to prevent oscillation.

4.3 Step 3: Indoor Antenna Placement (Releasing Enhanced Signal)

• Connect the 3m indoor coaxial cable to the 'MOBILE' port on the booster unit.
• Attach the indoor whip antenna to the other end of the 3m indoor coaxial cable.
• Position the indoor antenna in the area where you desire signal coverage.

4.4 Step 4: Power Connection

• Connect the power supply to the booster unit and then plug it into a power outlet.
• The booster will power on, and indicator lights will show its operational status.

5. Operation

Once installed and powered on, the signal booster operates automatically. It intelligently performs automatic gain control and oscillation cancellation to maintain optimal performance. You should observe an improvement in cellular signal strength on your mobile devices within the coverage area of the indoor antenna.

Figure 5: This diagram illustrates the booster's function: it receives a weak signal, boosts it, and then transmits a strong signal for 2G, 3G, and 4G networks.

5.1 Coverage Area

The booster provides broad coverage, enhancing signals in various indoor environments such as homes, offices, stores, and warehouses. The actual coverage area may vary depending on the outdoor signal strength and building materials.

6. Maintenance

The Generic Cell Phone Signal Booster requires minimal maintenance. Follow these guidelines to ensure longevity and optimal performance:

• Keep Clean: Periodically wipe the booster unit and antennas with a soft, dry cloth to remove dust.
• Cable Integrity: Regularly inspect all coaxial cables for any signs of damage, kinks, or loose connections. Damaged cables can degrade performance.
• Antenna Position: Ensure outdoor and indoor antennas remain securely mounted and correctly oriented. High winds or other environmental factors can shift their position.
• Ventilation: Ensure the booster unit has adequate ventilation and is not covered, to prevent overheating.
• Power Supply: Use only the provided power supply. Do not expose the unit to extreme temperatures or moisture.

7. Troubleshooting

If you experience issues with your signal booster, refer to the following troubleshooting steps:

7.1 No Signal Improvement

• Check Outdoor Signal: Verify that there is an existing outdoor signal of at least 1-2 bars. The booster cannot create a signal where none exists.
• Antenna Orientation: Ensure the outdoor antenna is pointed towards the nearest cell tower and is not obstructed.
• Cable Connections: Confirm all coaxial cables are securely connected to both antennas and the booster unit.
• Antenna Separation: Increase the physical separation (distance) between the outdoor and indoor antennas. Insufficient separation can cause oscillation, which reduces performance.
• Frequency Band: Re-check that your mobile network operates on the supported frequency bands (Band 1/3/8).

7.2 Flashing Indicator Lights / Oscillation

• Flashing lights often indicate oscillation (feedback loop). This occurs when the indoor antenna picks up the signal from the outdoor antenna.
• Increase the physical distance between the outdoor and indoor antennas. Try to create both vertical and horizontal separation.
• Ensure there are physical barriers (walls, ceiling) between the two antennas.

7.3 Power Issues

• Ensure the power adapter is correctly plugged into the booster and a working electrical outlet.
• Check if the power outlet is functional by plugging in another device.
