Comparing Lower Layer Splits for Open Fronthaul Deployments

The transition to open RAN (Radio Access Network) based on interoperable lower layer splits is gaining significant momentum across the mobile industry. However, where best to split the open RAN is a complex compromise between radio unit (RU) simplification, support of advanced coordinated multipoint RF capabilities, consequential limitations on transport delay budgets as well as bandwidth expansion. This post compares the two leading alternative splits for realizing an interoperable open RAN.

Security in Open RAN Networks

Many mobile network operators are considering deployment of open, decomposed, and modular radio access networks for 5G advanced wireless networks. The business rationale for adopting this network architecture is evident in light of the current state of the supply chain for network infrastructure. The current pool of vendors for technology in the Radio Access Network […]

Open vRAN Collaboration to Accelerate Solution Deployments

Today, World Wide Technology (WWT) announced a collaboration with Cisco, along with Altiostar, to develop an Open vRAN blueprint and validation lab and program for service provider networks.  I’d like to take a few minutes to explain why this agreement is significant for our service provider customers.
