If you are living in a rural area, you might probably have experienced poor cell reception. This is because the cell signal that comes to you might not have enough strength to make calls or browse the internet. The only solution for this is to increase the cell signal strength.

A signal booster is the best way to increase the strength of the cell signal inside your home. Many rural households are installing this device to ensure uninterrupted cellular reception all the time.

However, due to some faults during the installation process, some issues will occur to the signal booster system that can affect the cellular reception. In this article, we will talk about the common signal booster problems and their solutions.


Oscillation will occur in any type of electronic device where a positive loop exists between the input and output signals. This phenomenon is also called as feedback or feedback loop. You may have probably experienced feedback in a device with a speaker and microphone. The microphone catches the amplified audio from the speaker and sends it back to the system. This is known as audio feedback. This can also happen to a cell phone repeater system.

The oscillation that happens to a cell phone repeater is different from that of audio feedback. There is a positive feedback loop between the input and output signals. We know that the cell phone booster has three components, which are the external antenna, amplifier, and the internal antenna.

The external antenna of the signal booster receives the cell signals coming from the cell tower and sends it to the amplifier unit. The cell signals will be boosted by the antenna and the internal antenna will redistribute the boosted cell signal to the nearby cellular devices. When the external antenna captures the boosted cell signals rebroadcasted by the internal antenna, it is passed through the booster signal again and a positive feedback loop is created.

Oscillation can cause serious damage to your local cell reception and may even damage your signal booster. The feedback loop will create interference in the cell signal and you won’t be able to make calls or browse the internet. It is very important to solve this problem because the oscillation can cause noise in other frequencies as well. That means the cell reception of other devices within the vicinity will also be affected by the oscillation of the signal booster regardless of the cellular network they use.

Most of the available modern signal boosters will shut down or automatically reduce their functions when they detect oscillation or feedback loop. This will prevent any possible damage to the cell phone repeater system.

Solution For Oscillation Problem

The primary solution for oscillation is antenna separation. One of the main causes of oscillation is installing both external and internal antenna close to each other. When both these antennas are close, the signals emitted from the internal antenna will be captured by the external antenna. If you are able to mount the antennas far apart from each other, you can eliminate the oscillation to some extent.

If you cannot separate the external and internal antennas far enough to avoid oscillation, you can make sure that both the antennas are pointed away to ensure there is no feedback loop. Another thing you can do is to put a shield between the antennas so that the external antenna cannot capture the amplified cell signals rebroadcasted by the internal antenna.


Another problem that can occur to the cell phone booster system is overload. This problem is caused when the external antenna of the signal booster is very close to the nearest cell tower. When the external antenna is too close to the cell tower, the incoming cell signal will be too strong for the signal booster and it will result in signal overload.

This can happen with the cell signals of any network carrier’s cell tower. Most of the modern cell phone boosters can detect overload and this is usually indicated by the blinking of orange light on the amplifier unit.

Solution For Overload

To ensure that your signal booster is not overloaded, you need to change the direction of the external antenna so that it can receive a signal that is not so strong for the booster. You can use a unidirectional antenna for capturing cell signals from a particular direction.

Another solution for overload is connecting a filter between the amplifier and the external antenna. The filter can reduce the frequency of the signal and thereby avoiding any chance of signal overload. If both the solutions are not working, the best way to avoid overloading is by installing another signal booster system. Since the installation of a signal booster is cheap, another booster system is an effective approach to overloading problems because it can help in covering the signals of multiple network carriers.
