No electronic device is immune to possible malfunctioning during their lifetime, and so, it is important that you give proper attention to their maintenance. Cell phone booster is one of the most popular electronic solutions to cellular signal issues that affect the quality of your voice calls and slows down the internet speed.

The device action is similar to that of a signal repeater that works on the existing signals to boost them and then retransmit them to the next point. In this article, we are focusing on the common issues that affect signal booster working and the key maintenance tips for the device.

Issues Affecting Signal Booster Performance

Commonly reported issues that affect signal booster performance include oscillation and overload. In order to understand oscillation and overload, it is important that you develop a basic understanding of cell phone booster components and the overall working of cell phone booster.

Cell phone booster has three main components. They include an outdoor antenna, amplifier, and indoor antenna. Signal booster working begins at the outdoor antenna end when the antenna picks up the outdoor cellular signals. The captured signals are sent to the amplifier, the key unit of cell phone booster. The amplifier increases the strength of the signals it receives and then sends them to the indoor antenna, which performs the function of broadcasting the amplified signals.


The oscillation occurs when the outdoor antenna captures the amplified signals sent out by the indoor antenna and forces them through the booster system again. The phenomenon can affect the performance of the cellular signal booster adversely. Modern cell phone boosters come with oscillation detecting features as a result of which the booster shuts down in advance on detecting oscillation to save the components from damage.

The short distance between the outdoor and indoor antenna is reported as the main reason for oscillation. The best way to reduce signal booster oscillation is to increase the distance between the antennas. This should be taken care of at the time of installation itself.


When the outdoor signals are quite strong and they are amplified by the booster system, the issue of overload might arise. It is especially expected when the outdoor antenna is very close to the transmitting tower. Blinking orange lights is the typical indicator of signal overload in cell phone boosters.

Overload may at times be noticed even after some months post-installation of boosters. That could be because a new cell tower came in between the outdoor antenna and your carrier tower. Redirecting the external antenna is the most common solution to signal overload. It allows signals of comparatively low strengths to reach the outdoor antenna, thereby protecting the whole booster system from overload. However, the solution does not necessarily work every time. Take for instance the situation we discussed before, a new carrier tower coming in between the outdoor antenna and your carrier’s tower. In situations like this, it is advisable to incorporate a signal filter into the system to filter out undesired signals. The filters are connected in between the outdoor antenna and the amplifier.

Maintenance Of Cell Phone Booster

Signal booster performance may be affected by weather phenomena, as well as indoor conditions and traffic around booster components. Here are some of the maintenance tips of the cell phone booster.

Check All The Connections

Unless the connections are established properly, the signal booster’s working efficiency will be compromised. Loose connections between antennas and booster will fail to transmit signals with full efficiency. Overly tight connections increase the chances for the breaking of cables. Periodically check the connections to ensure that all are adequately set.

Ensure That There Is No Wear And Tear Of The Connecting Cables

Over time, there are chances for cables to be torn or pinched. All of this has an adverse impact on the performance of the booster. Ensure that the cables are not torn or pinched, and if you find any in those states, replace the cables.

Increasing the lifetime of signal boosters is only possible if you take enough care in its maintenance procedure. Realize that the maintenance of boosters has equal importance as that of their installation.

Keep The Booster Components Away From High Traffic Area

The outdoor antenna is kept at outdoor locations, possibly on the terrace or outer walls of your building. In case of vehicle boosters, the antenna is fitted on the vehicle roof so that the metallic roof acts as a shield that prevents oscillation. The amplifier and indoor antenna of home as well as vehicle boosters are kept at indoor locations.

Whether it is the outdoor antenna, amplifier or indoor antenna keep it away from high traffic areas. Do not place them on points through which people pass frequently, as the chance for damage is high.
