Cellular signal issues are not rare, especially in places with various signal-blocking features. If it isn’t that easy to get rid of the obstructions to cellular signals, then the only option you are left with is a signal boosting device like a cell phone booster.

Cell phone booster can bring significant improvements to the signal strength at your place. The device resembles a signal repeater. Cell phone booster takes in weak cellular signals, boosts them and broadcasts the amplified signals within its coverage area.

Components Of A Cell Phone Booster

A general understanding of the cell phone booster components is important to develop a better idea about the factors that affect the device performance and the remedial measures.

Cell phone booster has three major components; the outdoor antenna, amplifier and indoor antenna. The outdoor antenna captures the external cellular signals and passes them on to the amplifier. The major function of signal amplification is done by the amplifier. After boosting the signals, the amplifier sends them to the indoor antenna that broadcasts the amplified signals throughout its coverage area.

What Are The Issues That Affect The Performance Of Cell Phone Booster?

If you notice the strengths of the cell phone booster output to be less than the expected levels, you have to figure out the reasons for the poor performance of the device. Some of the factors that affect the performance of cell phone booster include:


Oscillation refers to the formation of a positive feedback loop between the output and input. In the case of a cell phone booster, a positive feedback loop is established between the outdoor antenna and indoor antenna.

Oscillation in cell phone boosters occurs when the signals sent out by the indoor antenna are captured by the external antenna. These signals are then forced through the booster system again, leading to oscillation.


Overload is caused when too strong cellular signals enter the booster system via the external antenna. The issue is often caused when the outdoor antenna is very near to the cell tower. The blinking orange light in the booster device is the typical indicator of overload in a cell phone booster.

How To Solve Performance Issues Of Cell Phone Boosters?

Most performance issues of cell phone booster are caused by the lack of planning when it comes to the installation of the device. Here are some tips to solve the performance issues of cell phone booster.

Avoiding oscillation: Usually, the short distance between the outdoor and indoor antenna is the cause of oscillation. Ensuring antenna isolation by increasing the distance between the outdoor and indoor antenna is the perfect solution for this problem. When it comes to vehicle cell phone boosters, maintaining the distance will not always be practical. But the metal roof of the vehicle will act as a shield between the donor (outside) antenna placed on the roof and the receiver (inside) antenna placed inside the vehicle.

Avoiding overload: Overload can be avoided by directing the external antenna to some point away from the cell tower. However, if the overload is caused by another carrier’s tower that comes between the external antenna and your carrier’s tower, redirecting the external antenna is a bad idea because your signal reception will be affected. In such cases, you can attach a frequency filter between the external antenna and the amplifier. This way you can filter out the unwanted signals causing overload.

Choose the appropriate point for mounting the antennas: The antennas, external and internal have to be installed at the right points lest the booster performance will be adversely affected. It is important to place the external antenna at an outdoor point that receives maximum available strength. To determine the ideal installation point, test the outdoor signals using a signal meter.

The indoor antenna has to be placed at a point that requires boosted signals the most. They have to be installed in such a way that all points where you are likely to use cell phones are covered.

Give proper attention to cable type and length: The components of the cell phone booster are connected to one another via cables. Choose high-quality cables in cell phone booster installation and also take adequate care to minimize the cable length as possible. The longer the cable length, the greater will be the rate of signal loss.

Choose the right antenna: Outside and inside antenna is of different types. To ensure you get the expected output from the cell phone booster, choose the right antenna type. Omni-directional outside antenna captures signals coming from all directions whereas unidirectional outside antenna can capture signals coming from a single direction. If your place has many cell towers around and you require multi-carrier boosting, choose an omni-directional antenna. Choose a unidirectional antenna if your place has a single cell tower.

Most performance issues of cell phone boosters can be avoided by taking adequate care during the installation.
