Gives you faster data transfer speeds, clearer voice quality, less interrupted calls and more up-to-date information
Outstanding product features - Portable mobile phone signal booster with AGC (automatic gain control) function, which can intelligently detect the existing signal strength and adapt for the best performance. LED lights design can monitor signal amplifier working condition. Inactivity mode saves unnecessary power
Multi-scene applications - This mobile phone signal booster is suitable for improving the signal in homes, offices, basements, metal buildings and rural areas. With multi-room and multi-user functions, you can share a strong signal with family, friends or colleagues within the coverage area
Applies to all network operators & band 7/20 - This mobile phone reception amplifier can improve the data signal for DE networks, including O2, T-Mobile to band 7/20 (2600/800 MHz)

* Warm Tips * -- To ensure reliable switching, the transmission power of the front-end device must reserve a margin of at least 3 dB, i.e. the minimum transmission power of the front-end device must not be less than 1 dBm, otherwise this may cause instability of the receive/send switch.
* Performance* -- Built-in intelligent receive/transmit differentiation circuit, does not require front-end equipment to provide receive/transmit switch control signals. The transmission gain is manually adjustable, which is convenient for compatible wireless devices with different transmission power.
* Operation mode* -- This wireless range extension module works by default in the received state and amplifies the received signal. When it is detected that the front-end device is sending external signals, it immediately switches to the transmission and amplification state. The transmission gain is manually adjustable, which is convenient for compatible wireless devices with different transmission power.
* Maximum transmit power* -- 31.5 dBm (1.4 W) at 3.7 V supply voltage; 33.5 dBm (2.3 W) at 5.0 V supply voltage; 34.5 dBm (2.8 W) at 6.0 V supply voltage
* Applicable frequency band * -- Two-way signal power amplifier modules of the AB-IOT-433 / AB-IOT-510 / AB-IOT-868 series are suitable for various applications in the frequency bands 433MHz (420MHz-480MHz), 510MHz (470MHz-520MHz) and 868MHz (Europe Europe Europe 863MHz-870MHz). Its compact size and convenient use facilitate the development of products for high performance and remote applications in this frequency band.
