📖 Product Manual
Indoor Signal Repeater (Signal Booster) series is an ideal solution for wireless systems in small/medium businesses and home users looking to enhance indoor wireless connectivity. It is connected via coaxial cable to a Donor Antenna and Service Antenna. The Donor Antenna is placed outside where it has easy access to BTS signals, and the Service Antenna is placed in the building to extend coverage to blind areas. Automatic Gain Control (AGC) prevents saturation, maintaining high voice quality and avoiding network interference. Its super compact design and easy installation make it ideal for individual customers.

❓ Frequently Asked Questions
Q1: Which frequencies does this booster support?
A: It supports a wide range of frequencies including 900, 1800, 2100, 2600, 850, and 1900 MHz. Options for single, dual, tri, quad, and quint bands are available.
Q2: What is the effective coverage area?
A: Under optimal conditions without obstructions, the booster can cover an area of approximately 3000 to 6000 square meters.
Q3: How does the Automatic Gain Control (AGC) work?
A: The AGC automatically adjusts the gain to prevent the booster from over-saturation, ensuring high voice quality and minimal network interference.
Q4: Is the installation process complicated?
A: No, it is designed for easy installation. Individual users can set it up without deep professional knowledge or specialized instruments.
Q5: Can I manually adjust the settings?
A: Yes, the device features a Digital Display Panel and Manual Gain Control (MGC) switches for easy and efficient parameter adjustments.
Q6: What is the purpose of the LED indicators?
A: The Power LED indicates system status, while the Alarm LED (Red/Green) warns of self-oscillation or excessively strong input signals.
