A cell phone booster system is a necessity if you are living in an area where the cell reception is very poor. The cell phone booster amplifies the existing cell signal in an area and prevents call drops, slow data speed, undelivered text messages, etc.
Sometimes your cell reception may not be good even if you install a signal booster. That might be because of oscillation. Keep on reading to find more about oscillation and how to prevent it.
What Is Oscillation?
Oscillation is generally known as feedback and occurs when the two antennas of a signal booster, internal antenna and external antenna, are mounted close to each other. The oscillation can harm the cell phone booster system. It may cause a reduction in the strength of the cell signal or may turn-off the signal booster system.
When the oscillation is really bad, it will be shown by a red indicator light on the amplifier unit. The red indicator light means the amplifier has shut down for preventing oscillation that may damage the signal booster system or even the cellular network itself.
The oscillation occurs when the external antenna picks up the amplified cell signals that are rebroadcasted by the internal antenna. Your cell phone might receive the highest possible cell signal during oscillation but the signal would be bogus with background clatter.
How To Prevent oscillation?
Antenna separation is the most viable solution for oscillation in a cell phone booster. For preventing oscillation, you need to mount the external antenna and the internal antenna of the signal booster at a significant distance from each other.
If the external antenna and the internal antenna are close to each other, they will create a feedback loop where both the antennas pick up each other’s signals. According to the Federal Communication Commission, the amplifier of a cell phone booster system should have the capability to automatically detect oscillation and correct it immediately.
Once the cell phone booster detects oscillation, it reduces the gain or the ability to amplify the cell signal, for autocorrecting oscillation. When the gain is reduced, it lowers the coverage area of the signal booster. According to FCC regulation, the signal booster should power itself down for eliminating any possible damage that could happen to the cellular network.
Most of the time there is no need for professionals to install a signal booster system in your home. However, you need to take extra care while installing the signal booster to avoid the problem of oscillation. When you install the signal booster yourself, make sure that there is enough distance between the two antennas and that there are no other antennas near them.
