What is automatic gain control?
Automatic gain control (AGC) regulates and maintains consistent signal strength in a cell phone signal booster. It optimizes the performance of the signal booster by automatically adjusting the gain (amplification) of the incoming signal.
AGC monitors the strength of the incoming signal from the cell tower and adjusts the amplification level to ensure that the boosted signal provided to phones and other cellular devices—like hotspots and cellular-enabled tablets—is within an optimal range.
When the incoming signal is weak, AGC increases the signal booster’s gain to amplify it and provide a stronger output signal to the devices. This helps improve the reliability of the connection and increases the indoor coverage area of the booster.
On the other hand, if the incoming signal is too strong, AGC reduces the gain to prevent signal distortion and avoid overpowering or overloading cellular devices. This prevents signal interference and ensures that the amplified signal remains within the appropriate range for optimal performance.
By continually adjusting the gain based on the incoming signal strength, automatic gain control helps maintain a stable and reliable signal for cell phone users, enhancing call quality, data transfer speeds, and overall cellular connectivity.
