Solve The Oscillation Problem In A Signal Booster

Cables used in signal boosters.

Oscillation is one of the most common problems that you might face when installing a signal booster at your home or office. This condition occurs when the antennas of the signal booster system are too close to one another and starts to capture each other’s signal. Oscillation is also called feedback and it needs to be corrected immediately.

How To Prevent Oscillation?

The best way to prevent oscillation in a cell phone booster is by properly installing all the components of the cell phone booster, especially the outdoor and indoor antennas. You need to ensure that the indoor and outdoor antennas are not installed close to each other. 

It is highly important to correct the feedback because it may harm the reception and transmission of cell signals. If you do not solve this problem, it will eventually damage the cellular network. According to the FCC, all the cell phone boosters should have the capability of automatically detecting oscillation and correcting it immediately.

When the signal booster detects oscillation, the gain will be reduced automatically or the cell signal amplifying ability will be toned down to autocorrect the oscillation. The reduction in gain reduces the coverage area of the signal booster. According to the FCC regulation, the signal booster should power itself down to avoid any possible damage to the outside cellular network. 

Separate The Indoor And Outdoor Antennas

You can easily prevent oscillation by choosing the right location for your outdoor and indoor antennas. The installation process of an in-house signal booster is pretty simple. But you need to keep in mind that the outdoor antenna and indoor antenna should have sufficient distance between them. Most of the installation guide helps you to find the minimum separation distance between the antennas.

It is recommended to have at least 25-30 feet of vertical separation between the outdoor and indoor antennas. In any case, you cannot achieve this vertical separation, you should compensate it with the horizontal separation. You can also avoid oscillation by installing both outdoor and indoor antenna 180-degrees apart. If there is a wall or roof between the two antennas, it will also help to reduce the minimum separation required to avoid oscillation.

What Is Overload And How To Fix It?

This condition occurs when the outdoor antenna is too close to the cell tower. This causes the cell signals to come in strong and results in signal overload. The best way to fix overload is by pointing the outdoor antenna away from the cell tower. You can also change the location of the outdoor antenna to avoid signal overload.
