Usually, in some enclosed indoor and enclosed spaces such as basements, elevators, parking lots, etc., the mobile phone signal will become very weak, which is a common problem we encounter. Callboost mobile cell signal booster can provide one-stop help to solve weak signal problems.Let's go!

In the field of mobile signal amplifiers, Automatic Gain Control (AGC) and Automatic Level Control (ALC) are important technologies used to adjust signal strength.AGC focuses more on real-time response to signal transient changes, and can quickly adjust for sudden large signal peaks to avoid saturation distortion; For weak signals, increase the gain to ensure that they can be received correctly.ALC tends to focus more on long-term level balancing, maintaining overall signal stability and preventing long-term level drift from affecting reception quality, especially in environments with mixed signals or network congestion.
