amplifying all kinds of mobile phone signal within 1-30m²and the best assistant for calling.
- Automatically amplifying mobile phone signal and no testing instrument
1. Automatically adjusting the uplink and downlink gain
The device will automatically check input power and control output power when connection with power supply, it will automatically calculate the gain of downlink to adjust the uplink gain after 5 minutes, keeping the performance of the device system and amplifying balance to achieve adjusting uplink and downlink gain function.
2. Isolation checking function
The device will checking the antenna isolation after connecting with power supply, if the antenna isolation does not meet the device installation requirement, the indication light will indicate timely and automatically control the device to reduce gain until the device does not cause self-excitation, it will protect the safety of repeater and no interference of mobile phone network.
3. Power indication function
The device will automatically check the output power after connecting with power supply and timely indicate to achieve good communication and largest coverage.
4. Automatically installation indication
The device will timely and accurately display isolation, power etc information to guide the user without any testing instrument to smoothly operate and amplify coverage.
