How Full Signal Booster Works

Important Knowledge before Installation

In order to make a successful installation, there is a most critical information you need to know- You should Prevent Self-oscillation during installation. Self-oscillation happens when outdoor antenna and indoor anten- na are installed too close to each other. When self-oscillation hap-pens, instead of picking up signal from the Operator Cellular Tower, the outdoor antenna picks up the transmitted signal from the indoor antenna, and repeatedly boosted, thus it will generate a signal loop with a lot of noise which is called Self-oscillation. When self-Oscillation happens, the booster will not boost useful signal from your cellular operator, so the system will not work.

To prevent self-oscillation during the installation of a cellular signal booster, it is crucial to follow the given guidelines:

1. Outdoor antenna and indoor antenna need to be separated with an object or a distance. It is essential to have a physical barrier, such as a wall, between the outdoor and indoor antennas. This helps to prevent the transmitted signal from the indoor antenna from being picked up and amplified by the outdoor antenna.
2. Outdoor antenna and indoor antenna should not point to each other: Ensure that the outdoor antenna and indoor antenna are not facing each other directly. This reduces the chances of the outdoor antenna picking up the signal transmitted by the indoor antenna.
3. Maintain a minimum required separation distance: The outdoor antenna should be placed as far away as possible from the indoor antenna to minimize the risk of self-oscillation. The minimum recommended separation distances are:
   • Horizontal Distance: 20 feet (6 meters)
   •  Vertical Distance: 13 feet (4 meters)

By adhering to these guidelines, you can prevent self-oscillation and ensure that the cellular signal booster functions effectively by amplifying the signal from the cellular operator rather than creating a loop with noise.

1. Point to the tower
2.  Antennas back to back
3. Two wall barriers

1. Not pointing to the tower

1. Point to the tower
2.  Antennas back to back
3. No barriers, make sure vertical distance enough

1. Two antennas facing the same direction
2. Vertical distance might not be enough

QUICK INSTALLATION GUIDE

Select the Location for the Outside Antenna

Note: This is the most critical step and will determine the perfor-mance of your booster. Generally, the strongest signal will be locat-ed on the side of your home facing to the nearest cell tower from your cellphone operator.

1.  Walk around your house with your cell phone, search for the place where your phone gets the strongest signal reception, at least 3-4 signal bars.
2. Make a few phone calls there to check the call quality, if it is clear and stable, that will be an ideal position to place the outdoor anten-na

Install the Outdoor Antenna

Install the outdoor antenna on the roof above the location you found in Step

1. Make sure the antenna points towards the direc-tion where your cellular operator’s tower is. Connect the Outdoor cable to the antenna, waterproof the connectors with tapes.
   Note:

2.  The Outdoor Antenna should be as far away as possible from the Indoor antenna.
   Minimum required separation distance between indoor and outdoor Antenna:
   Straight line distance: Over 30 Feet (10 meters), or Horizontal distance: 20 Feet (6 meters ) Vertical distance: 13 Feet ( 4 meters)

3. To prevent lightening, the height of the outdoor antenna should be lower than the highest point of your house.

Place the indoor antenna at where strong signal is needed most. The Indoor Antenna is a directional antenna, it needs to be installed on the wall. Choosing a location facing all over your home will help to maximize your coverage area.

Note:

1. Make sure the Outdoor Antenna and Indoor Antenna are not facing to each other.
2.  Make sure there is sufficient separation between the Outdoor Antenna and Indoor Antenna.

Antennas,Power on

Connect the Outdoor Antenna cable with “OUTDOOR ” port on the cellular booster, and connect the Indoor Antenna cable with “INDOOR ” port on the repeater. Then power on the booster and check the coverage.

Optimize Coverage

1. Signal Bars
   The signal bars on the LCD screen of the repeater indicate the signal strength picked up by the outdoor antenna. More bars represent better coverage that the repeater can produce. Aim for at least 3-4 signal bars to achieve optimal performance. If you’re not receiving ideal signal reception, try rotating the outdoor antenna to different directions until you achieve better signal reception.

2. Input Range
   The input range of-50 to-70dB represents the signal strength received by the booster. For better coverage, aim for a signal strength around-60dB or higher. This indicates a stronger input signal for the repeater to amplify.

3. Output Range
   The output range of 0-20dBm represents the power level at which the booster is transmitting the amplified signal. For better coverage results, aim for an output power around 10dBm or higher. This ensures a stronger and more reliable signal distribution throughout the indoor area.

4. Isolation (ISO)
   The ISO sign represents the isolation between the outdoor antenna and the indoor antenna. When the ISO indicator is on, it indicates that the separation between the antennas is insufficient, which can result in poor coverage. To address this, increase the distance between the antennas and ensure they are not facing each other. This helps to minimize interference and maximize the effectiveness of the repeate

SAFTY GUIDLINES

Important guidelines and regulations for the safe and proper use of the cellular repeater.

1. Power Supply: Only use the power supply provided with the repeater package. Using any other power supply may result in improper functioning or damage to the device.

2. Antenna Safety: Ensure that any antenna used with the repeater is located at least 8 inches (20 centimeters) away from all persons. This is to minimize potential exposure to radio frequency (RF) energy.

3. Compliance with FCC Rules: The repeater has been tested and found to comply with the limits set for a class B digital device under Part 15 of the FCC Rules. These limits are designed to protect against harmful interference in residential installations.

4. Harmful Interference: If the repeater causes interference to network operators or other communication systems, it is recom-mended to take the following measures:
   • Relocate the Outdoor Antenna.
   • Increase the separation between the Outdoor Antenna and Indoor Antenna.
   • Seek assistance from the supplier or local installers for further guidance.

5. Compliance with Regulatory Requests: If requested by the FCC (or ISED in Canada) or a licensed wireless service provider, it is manda-tory to cease operating the device.

It is crucial to adhere to these guidelines to ensure proper function-ality, minimize interference, and comply with regulatory require-ments. If you have any specific concerns or questions, it is advisable to consult the supplier or seek assistance from local professionals experienced in installing and operating cellular repeaters.

After installation, the signal improvement is not significant, and the indoor coverage area is limited| 1. Adjust the position or direction of the outdoor antenna, try to get a better signal reception.
2.Check if the cables are properly connected.
3. Raise the outdoor antenna so that it can receive better signal.
4. Replace a higher gain outdoor antenna
The phone signal is full, but the call quality is poor| Check the booster “Work Indicator”， if any of the lights is in red, it indicates that the separa- tion between the antennas is insufficient. It is essential to increase the distance between the antennas, or increase physical barriers, such as a wall, between the outdoor and indoor anten- nas. Make sure the antennas are not facing to each other, then restart the booster.
