Introduction to Cell Phone Signal Booster (Signal Repeater):
The high-power intelligent display GSM990 mobile phone signal amplifier is suitable for areas with the intelligent display GSM990 network (TX-890～915 RX-935～960). This product has been successfully used in mainland China, the Middle East, Southeast Asia, Europe and other countries and regions, with very obvious effects. It is the most effective and most economical equipment to make up for the lack of mobile communication network coverage and expand the coverage of base stations, eliminating blind areas.
Features: Low noise, full duplex, single antenna design, variety of model styles, suitable for different countries and regions with various frequencies, all machines are equipped with automatic gain control, stable performance, high gain, strong penetration ability, coverage area up to 100-1000 square meters.
