The Market for DUs in OpenRAN Networks

Traditionally, monolithic network deployments have incorporated a base station at the cell tower, which has included therein all the necessary data processing to then forward the data on to the core of the network. Among the functions found in a legacy base station were those of:

  • The Radio Unit (RU), which acts as a transceiver to digitize the transmission
  • The Distributed Unit (DU), which converts a signal from one form to another, aggregates all the data, and prepares it to be physically transmitted over a communication channel to the mapped address for delivery
  • The Centralized Unit (CU), which further processes the IP traffic, including QoS, compression, reordering and security such as encryption/decryption and IPSec

Ethernity Networks Ltd (LON:ENET) is a leading provider of networking and security software solutions on Field Programmable Gate Arrays (FPGAs), incorporated into SoCs, SmartNICs, and network appliances. Ethernity was founded in 2004 and has its technology deployed in over 600K systems worldwide, connecting over 100M end users.
