ATNJ New Upgrade amplificador de seal celular 2g 3g 4g LTE mobile phone signal detector
The LCD booster of the latest generation, ATNJ NB-GDW is used to improve weak GSM signals at two different frequencies. The LCD display shows a signal level, setup recommendations, error notifications, power, and ALC data. Moreover, the NB-GDW comes with one more port for an additional interior antenna that enables its user to redistribute the enhanced signal.
This model guarantees effective amplification in middle-sized houses and offices, shops, and other areas up to 300 m² (3200 ft²).
The device boosts GSM signals at 900 and 1800 MHz simultaneously. 900 MHz is the most spread frequency for GSM signal transmission in the European Union and all over the world. 1800 MHz is mostly used as an additional frequency to 900 MHz and in certain regions as the main one. Consequently, the dual band amplifier will suit users of mobile providers working at different frequencies.
