Virtual RAN

A way of implementing the Radio Access Network (RAN) where some or all of the baseband functions are run as software on general-purpose servers.

AbbreviationvRAN
Categorynetwork

Overview

vRAN is a key step toward Open RAN. It involves 'decoupling' the RAN software from the proprietary hardware. This allows operators to run their radio network on the same type of servers used in data centers.

Key Components

  • vCU (Virtual Centralized Unit): Handles non-real-time radio functions.
  • vDU (Virtual Distributed Unit): Handles real-time, time-sensitive radio functions.
  • RU (Radio Unit): The physical hardware (antennas and amplifiers) at the cell site.

Benefits

  • Scalability: Easily add capacity by spinning up more virtual instances.
  • Flexibility: Update radio features via software without visiting the cell site.
  • Cost: Potential for lower hardware costs over time.
