What is a Remote RDU?

A Remote RDU (Remote Radio Unit or Remote Radio Device Unit) is a telecommunications device used in wireless communication networks. It is typically installed near the antennas on cell towers and is responsible for transmitting and receiving radio signals to and from mobile devices. By placing RDUs remotely, closer to the antennas, network operators can improve signal quality and reduce power loss over long cable runs. Remote RDUs play a crucial role in modern wireless infrastructure, especially in distributed antenna systems and advanced cellular networks like 4G and 5G.
