Radio Frequency Remote Unit (RRU) Key Component for Wireless Signal Transmission

RRU is a device that converts baseband signals into radio frequency signals and amplifies them. It works with BBU to enable distributed deployment of base stations, effectively expanding signal coverage. Connected via fiber optics to reduce RF cable loss and improve signal transmission quality, RRU is commonly used for signal coverage in complex environments like urban areas and mountainous regions, enhancing the breadth and depth of communication networks.
