The high efficacy in boosting cellular signals and appreciable affordability has increased the popularity of cell phone boosters among the myriad of signal boosting solutions. They work with the available signals to amplify and send them to our cell phones.
What Is Oscillation In Cell Phone Boosters?
Before we go about giving the definition of signal booster oscillation, we have to begin by briefing about cell phone booster components. Cellular signal boosters have three major components, outdoor antenna, amplifier, and indoor antenna. The outdoor antenna captures the signals available outside and transfers them to the amplifier, which then works on the signals to boost their strength. The boosted signals are then sent to the indoor antenna that broadcasts them to the reception points that require boosting.
Now let us get into the definition of oscillation. The phenomenon that occurs as a result of external antenna capturing the signals transmitted by the indoor antenna is termed as oscillation. The overlapping of the signals establishes a feedback loop between the indoor and outdoor antenna, thereby disrupting the cellular network. It may damage the booster components.
How To Fix Oscillation
The primary cause of oscillation is the proximity of the indoor antenna to the outdoor antenna. Increasing antenna isolation by separating the antennas by greater distances is the most suggested solution for oscillation. Antenna separation can be practiced by either maintaining a horizontal distance between the antenna, vertical distance, or a combination of both. The horizontal separation distance is greater than the vertical separation distance. Some booster models come with adjustable knobs that can be turned on to bring down the amplifier gain. When the boosting capacity of the amplifier is limited, the feedback can be reduced significantly. However, this will have an adverse impact on the indoor coverage area.
Modern-day boosters have the ability to detect oscillation and the red lights flashing on the booster unit is an indicator of oscillation. To protect its components from damage due to oscillation, the booster either reduces power or shuts down altogether. It merely takes a few minutes for all of this to happen.
Although the oscillation in signal boosters does not produce any noise unlike in the case of oscillation in microphone, it can be detrimental to the effective working of the booster components, and hence has to be prevented at any cost.
