Oscillation And Overload In Cell Phone Boosters

Poor cellular reception is caused by one or a combination of various signal blocking factors that cannot be reversed in most cases. We cannot control weather changes that may disrupt cellular signals, meaning that a permanent solution is what that type of scenario requires. 

A cell phone booster is an ideal solution that promises strong cellular signals despite the limitations in your location. Like any device, signal booster and its operations can be affected by technical faults. In this article, we discuss oscillation and overloading, two phenomena that can affect a cell phone booster’s performance. 

What Is Oscillation?

Cell phone boosters have three major components, the external antenna, amplifier, and the indoor antenna. The external and indoor antennas perform the function of capturing external cellular signals and redistributing the boosted signals. Boosting cellular signals is the function of the amplifier. When the outdoor and indoor antennas are installed close to each other, the outdoor antenna may pick up the signals broadcasted by the indoor antenna, establishing a feedback loop between the antennas. This feedback is referred to as oscillation and affects the quality and strength of signal booster output. 

Increasing the distance between the antennas is the most recommended solution for signal booster oscillation. The antennas should have a minimum horizontal distance of 50 feet and a vertical distance of 20 feet between them. Cell phone boosters usually come with technical features that enable the signal booster to detect oscillation and shut down on its own in response. 

What Is Booster Overload?

Signals of very high strength entering the signal booster can cause booster overload. If the external signal strength and the antenna gain are quite high, there is a chance of too much signal being delivered to the booster system. In response to overloading, the booster shuts down itself. 

You have a range of solutions to choose from, in order to prevent overloading effectively. One of the easiest ways to deal with the issue is to buy an attenuator, which reduces the signal that the booster unit is receiving. 

Changing the alignment of the external antenna or relocating it is another solution for overloading. You may place your antenna in a spot that receives comparatively weaker signals or turn it away from the direction of strong signals. 

Knowing about the technical issues of oscillation and overload helps you take proper care when installing a cell phone booster to avoid the problems beforehand.
