Mobile phone signal intensifier (Repeater) introduction:
   The upgraded GSM980 mobile phone signal amplifier is suitable for areas with networks (TX-890 ~ 915 RX-935 ~ 960). At present, this product has been successfully used in mainland China, Middle East, Southeast Asia, Europe and other countries and regions, and the effect is very obvious. It is the most effective and economical equipment to make up for the lack of mobile communication network coverage, expand the coverage of base stations and eliminate blind areas.
   Features: low noise, full duplex, single antenna design, various models and styles, various frequencies are suitable for different countries and regions, all machines adopt automatic gain control, stable performance, high gain, strong penetration ability, covering an area of 100-1000 square meters.
