Product Overview
This compact, low-power 5G signal amplifier is designed for small indoor areas of up to 100 square meters, including offices, bedrooms, studies and small shops. It amplifies 5G NR signals in the n41, n78 and n1 bands to address weak reception, interruptions and disconnections. Its low-power design, small size and simple installation are intended to meet relevant national radio equipment standards. It supports the 5G networks of China Mobile, China Unicom and China Telecom to improve signal strength and communications quality within the coverage area.
