Open RAN

Deliver an open, agile, software-driven network that enables richer services, with greater flexibility at a lower cost.

Open RAN -- a virtualized RAN on general-purpose hardware -- replaces legacy, single-vendor RAN solutions with a stable, scalable and 5G ready architecture.

Our Open RAN blueprint, validated in WWT's Advanced Technology Center, is an end-to-end turnkey solution to accelerate time to revenue while providing a rapid upgrade path to deliver secure 4G/5G services.

6 Critical Questions to Answer Before Deploying Open RAN

There is no one-size-fits-all Open RAN deployment. We've developed a set of critical questions that must be answered before service providers go too deep down the complicated path of Open RAN.

FAQ: How Can Open RAN Drive Efficiency, Enable Agility and Enhance 5G Adoption?

How does Open RAN reduce operating expenses? Will Open RAN change the role of the network operator? Will Open RAN evolve into an as-a-service model? All these questions and more answered.

Open RAN Program Enablement

WWT's Open RAN program enablement utilizes our Digital Supply Chain model, which helps service providers accelerate time to revenue by validating complex, multi-vendor solutions with speed in our Advanced Technology Center (ATC), then integrating them at scale in one of our global integration facilities.

ATC Innovation Ecosystem

$500 million lab to design, build and validate Open RAN architectures.

Supply chain & integration

4 million square feet of logistics space spread over four continents to simplify Open RAN deployments.

Professional services

Portfolio of services to help drive Open RAN strategy from idea to outcome to post-deployment support.

Help along every step of the way

We are able to assist operators along every step of the process -- from idea to outcome -- to make it easier to consume and deploy Open RAN on any scale. 

This program is flexible and designed to meet the needs of service providers no matter where they are at in terms of a network transformation journey. We provide customized plans to make sure operators get to deployment as quickly as possible.

Customized deployment models

Legacy RAN systems were handled by a baseband unit (BB) that is now virtualized to enable better scaling and resource pooling. Open RAN disaggregates the virtual BBU (vBBU) further into real-time, or Distributed Unit (vDU) and non-real-time, or Central Unit (vCU) functions. 

Typically, the vRAN software has very specific hardware requirements for the vDU component (real-time), which balance cost and performance. The vDU server nodes will have a configuration applied that allocates each CPU core carefully and will have specific hardware for offloading digital signal processing (DSP) functions.
