Cell phone boosters are used when you are facing poor cell reception in your house, office, or vehicle. It is an electronic device capable of increasing the strength of the cell signal to a usable level so that we no longer experience any call drops or slow data speed. The three main components of a signal booster are the outside antenna, the amplifier, and the inside antenna.
The outside antenna will capture the cell signal and the amplifier will boost those cell signals. The boosted cell signal will be then redistributed by the inside antenna to all the devices in the building.
One of the common issues that might hinder the performance of your cell phone booster is oscillation. You need to prevent this problem for avoiding the damage of your boosters. In this article, we will discuss oscillation and the best ways to prevent it.
What Is Oscillation?
Oscillation is one of the most common problems that occur in a signal booster. It happens when there is not enough separation between the outside and inside antennas. If there is not much distance between the outside and inside antenna, then the signals from your inside antenna will reach the outside antenna and it will result in oscillation.
Oscillation will create a feedback loop that can damage your signal booster. In addition to this, it will disrupt the cellular network itself. Most of the signal boosters available today can detect oscillation and take the corrective measures automatically. It will help to prevent network disruption and avoid damage to the signal booster.
The signal booster will reduce the gain for preventing the signals from the internal antenna reaching the external antenna when it detects oscillation. But when the gain is reduced, the performance of the signal booster will also be reduced. Moreover, the signal booster will shut itself off if the problem is not solved even after reducing the gain.
Overcoming Oscillation Problem
The best way to avoid this problem is by placing the outside and inside antennas at a significant distance from each other. There should be enough vertical and horizontal distance between the antennas. The vertical distance will have a great impact in reducing the oscillation than the horizontal distance.
If you are using an omnidirectional antenna, a horizontal separation will not have a significant impact in reducing the oscillation. However, if you are using a unidirectional antenna, make sure to point it away from the internal antenna for preventing oscillation. You can also introduce some hindrance between the antennas to prevent the problem of oscillation.
