The GR3F-A-Kit is a complete mobile network and internet signal booster (repeater) kit supporting 2G, 3G, and 4G/LTE connectivity. The device features AGC (Auto Gain Control), which automatically adjusts the incoming signal strength to maintain network stability and prevent system overload. This kit is designed to enhance mobile communication and create a reliable network in indoor areas with weak coverage, such as homes, offices, and underground facilities.
