One of the common problems faced by mobile phone users is poor signal reception resulting in bad call quality, reduced internet speeds, or even dropped calls. There are multiple ways you can resolve this, but one of the most reliable solutions is to use a cellular signal booster. These devices receive weak cellular signals, amplify them, and retransmits them to your cellular device. However, there are certain factors that you must take special care of, otherwise, it will reduce the performance of these devices. In this article, we will focus on methods to prevent oscillation and overload in signal boosters.
What Is Oscillation?
One common issue that you must avoid when installing a cellular signal booster is the formation of a positive feedback loop or oscillation between the outside antenna and the inside antenna. This usually happens when there is no minimum separating distance between them as stipulated by the manufacturer. Oscillation not only affects the signal booster, but also other cellular devices functioning in its operating range. Besides, it can also affect the cellular tower broadcasting the signal. Because of this, all signal boosters are required to have an auto shutdown or power reducing feature if it detects oscillation.
How To Fix Oscillation?
The first step in preventing oscillation is to avoid crosstalk between the inside and outside antennas. This can also be done by adjusting the gain of the amplifier unit of the cell phone service booster. Listed below are the separating distances for amplifiers of different gain.
- 80dB – 125 feet
- 70db – 110 feet
- 68dB – 80 feet
- 65dB – 70 feet
- 55dB – 55 feet
- 45dB –15 feet
- 40dB – 6 feet
- 30dB – 4 feet
- 20dB – 2 to 3 feet
Make sure that there is at least minimum separation between the antennas of the amplifier./
What Is Overload?
As mentioned in the introduction, a cell phone service booster boosts weak cellular signals to ensure good call quality and other cellular services. If the outside antenna is too close to the cellular tower, the incoming signal becomes too strong that it causes signal overload. This is usually indicated by the orange light blinking on the amplifier of the cellular signal booster.
How To Fix Signal Overload?
The best way to avoid this issue is to redirect the outside antenna so that the orange blinking light on the amplifier turns back to green. This can be done by changing the orientation or location of the antenna so that it will be shielded from the cellular tower. However, this might not work if the antenna is located between the towers of two carriers. In such a situation, the logical solution is to install a filter.
These are the points that you should bear in mind when installing a cellular signal booster to avoid the problems of oscillation and overload.
