How can I tell if my cell phone signal booster is working?

[LaErin]

To confirm your cell phone signal booster is functioning correctly, follow these steps: First, check the LED indicator lights on the booster unit. A solid green light typically means the booster is operating normally. Flashing green may indicate a weak incoming signal. A solid yellow light suggests a strong input signal with Automatic Gain Control (AGC) active, and flashing yellow might indicate self-oscillation with AGC. A solid red light signifies the power supply is off, and flashing red could mean self-oscillation without power shutdown. Second, evaluate your signal strength before and after booster installation. A notable improvement in signal bars indicates the booster is working. Third, test call quality by making calls or using data. Clearer calls and faster data speeds confirm proper function. If issues arise, such as no LED lights or poor signal enhancement, troubleshoot by checking the power adapter and connections to both indoor and outdoor antennas. Make sure the outdoor antenna is in a location with good signal reception, and ensure proper separation between the indoor and outdoor antennas to prevent feedback. If you're still experiencing problems with your signal booster, consider reaching out to customer service for help. They can provide additional support or suggest exploring higher gain antenna options for improved performance.
