While making a call or using the internet, having poor cell reception can be a frustrating experience. A lot of people experience such issues because of a large number of reasons. Sometimes, the poor cell reception can be caused by the long distances from the cell tower, whereas, in some other cases, the blocking of cell signals by the building materials might be the reason. Whatever be the case, having low signal quality inside your home, office, or vehicle can create a lot of difficulties for you.

If you are also experiencing such issues, then a signal booster can be helpful for you. These devices are capable of receiving weak cell signals and boosting them for providing better connectivity inside your building. Hence, signal boosters are becoming a great help for people who are suffering from different problems caused by poor cell reception.

Even though cell signal boosters can help you to solve various problems caused by low signal quality, there are some problems that can affect the performance of these devices too. Some of the common problems that can interfere with the working of your cell signal booster include oscillation and overload problems. Therefore, through this article, we provide you some important information you need to know about these problems and the ways to troubleshoot them.


Oscillation is one of the commonly found problems in signal boosters. It is a result of the signals from your inside antenna reaching the outside antenna. This can result in a feedback loop that can adversely affect the performance of your boosters.

Oscillation can interfere with the working of your cell signal boosters and they might even affect the cellular network. Therefore, most signal boosters now come with the ability to detect oscillation. If a booster detects the occurrence of oscillation, it will first reduce its gain to prevent the signals from your inside antenna reaching the outside antenna.

However, if the problem is still not solved, it will shut itself off for avoiding the damage. Hence, you will have to prevent oscillation for facilitating the better working of your boosters.

How To Troubleshoot Oscillation?

  • The first step you can try is to increase the distance between your antennas. Introduce vertical separation or horizontal separation based on your convenience. Even though both these options can work, vertical separation is more effective than horizontal separation.
  • If you are using a uni-directional antenna, try to point it away from the building. This will help to prevent the signals from the inside antenna reaching your outside antenna.
  • If both of the above solutions do not work, then try to introduce some barriers between your inside and outside antennas. Your chimneys, air-conditioning units, etc. can be beneficial for this purpose.


Your signal booster will be designed to accept signals within a particular range. If the strength of the incoming signals is beyond this threshold, then it can be too much for your booster to bear. This condition will lead to overload problems which cause your cell phone booster to shut itself off for preventing the damage.

Overload problems can occur if there are one or more cell towers at the close proximity of your antenna. Overload problems can occur with any tower irrespective of whether you are trying to boost the signals from that tower or not.

You can try some simple steps to prevent overload problems to regain the performance of your boosters. These steps are listed below:

How To Troubleshoot Overload?

  • If you are using a uni-directional antenna, then try to change its direction step by step for preventing the overload problems. But redirecting the antenna might not be always possible. If you are using an omni-directional antenna, or if the offending cell tower is near your carrier’s tower, or if your carrier’s antenna is causing overload problems, then this solution will not be applicable to you. In such situations, you might have to look for other solutions.
  • If the above step is not applicable for you, then try to relocate your antenna. Install your antenna in a spot where it receives fewer signals. However, this might also raise some issues. If there is another tower near the new spot where you relocate your antenna, then it will again result in overload issues.
  • If other solutions are not helping you, then you can use attenuators as your final aid. These devices are capable of reducing the strength of the incoming signals. You have to install attenuators between your external antenna and amplifier. This will be useful for attenuating the strength of the signals before they reach the amplifier. These devices can help you to effectively deal with overload problems.

Oscillation and overload are common problems associated with cell signal boosters. Both these problems can interfere with the working of your signal boosters. Therefore, you have to fix these issues for regaining their performance. The above tips can help you to troubleshoot these issues effectively.
