RRU (Remote Radio Unit) is a new type of base station equipment used for wireless coverage and signal amplification in wireless communication systems. RRU is essentially a small wireless signal connector, and multiple RRUs can be connected together to form the same wireless signal distribution system. Compared with traditional base station equipment, RRU occupies a small area and has lower power. Therefore, RRU can be placed in more flexible and smaller places for installation, such as telephone poles, rooftops, etc.
