Understanding the Radio Remote Unit (RRU): The Backbone of Cellular Connectivity
What is a Radio Remote Unit (RRU)? A Radio Remote Unit (RRU) , also referred to as a Remote Radio Head (RRH), is an integral part of modern cellular networks. Its primary function is to bridge the gap between wireless devices and the cellular network infrastructure, ensuring seamless communication. Core Functions of RRUs Signal Transmission and Reception The RRU is responsible for transmitting and receiving signals between the base station and wireless devices. It converts data into radio frequency (RF) signals for transmission and processes incoming signals for the network. Optical-to-Electromagnetic Interface Acting as a mediator, RRUs connect optical and electromagnetic signals, enabling efficient communication across varied technologies. Auxiliary Equipment Control RRUs also manage additional equipment such as cooling systems and power units, ensuring optimal operation. Anatomy of an RRU Transm...
