For starters, automation and cloud-native tooling are making Open RAN extra scalable, not much less
Regardless of the very actual progress made round Open RAN, just a few myths nonetheless linger. Many nonetheless imagine the expertise stays experimental, whereas others assume it’s only appropriate for restricted, rural deployments — not dense, city, or complicated RAN environments. Wind River CTO Paul Miller instructed RCR Wi-fi Information that these assumptions are outdated. In his view, Open RAN has moved nicely past early trials and is now a mature, carrier-grade expertise being deployed at scale.
Listed below are just a few of probably the most persistent myths nonetheless circulating:
Fantasy #1: Open RAN efficiency and optimization are missing
One widespread false impression is that Open RAN networks can’t match the reliability or efficiency of conventional RAN techniques. Miller pushed again strongly in opposition to that concept, pointing to years of ecosystem progress.
“Collaboration on requirements, well-defined interfaces, profitable Plug fests, vendor interoperability certifications have all helped develop the ecosystem, cut back interworking complexity, and productize open elements for a telco community,” he mentioned.
He added that executives from international CSPs have confirmed Open RAN deployments are comparable — and in some instances superior — to conventional RAN networks when it comes to reliability and efficiency.
Nonetheless, Miller famous that optimization in a disaggregated community appears to be like totally different from that in a monolithic one. Historically, tuning centered largely on RF efficiency, because the RAN stack itself was assumed to be validated and optimized. “The commonest misunderstanding is that tuning a disaggregated RAN is solely a virtualized model of tuning a conventional ‘monolithic’ RAN,” he defined.
As an alternative, complexity shifts into the cloud platform layer, together with {hardware} accelerators, real-time working techniques, and the software program wanted to ship the constant latency and jitter efficiency required by the 5G distributed unit.
Along with cloud platform optimization, Miller mentioned operators should additionally deal with tuning throughout a number of elements of the stack, together with:
- Energy consumption optimization
- Fronthaul and midhaul interface latency
- Useful resource pooling throughout compute, storage, and reminiscence beneath various masses
Fantasy #2: Open RAN is more durable to function at scale
One other lingering perception is that Open RAN introduces operational complexity that makes large-scale deployment unrealistic. Miller argued the other: that automation and cloud-native tooling are making Open RAN extra scalable, not much less. “Operational effectivity is the lifeline of a telecom community deployed at scale,” he mentioned. “Effectivity can solely be achieved by way of automating Day 0 to Day n operations of the community.”
He pointed to centralized monitoring and automation platforms as key enablers, changing vendor-specific processes with repeatable, software-driven workflows.
Collectively, he mentioned, these capabilities have helped remodel Open RAN right into a carrier-grade operational mannequin that matches — and in some instances improves upon — the effectivity of conventional RAN, whereas accelerating innovation and repair deployment.
Fantasy #3: Open RAN introduces new safety dangers
Safety has additionally been a significant concern since Open RAN’s early days, notably round accountability in a disaggregated structure with extra interfaces.
However Miller emphasised that Open RAN doesn’t inherently enhance danger. “When correctly carried out, it might probably strengthen safety posture by way of larger transparency, automation, and management,” he mentioned. Whereas Open RAN does develop the variety of interfaces in a telecom community, he argued it additionally permits a zero-trust, cloud-native safety mannequin that’s tough to attain in closed, proprietary RAN techniques.
Fantasy #4: TCO is the one metric that issues
Lastly, Miller mentioned Open RAN’s success shouldn’t be judged solely on value financial savings.
“Whereas TCO is a compelling metric to measure the success of Open RAN, you will need to perceive the worth a disaggregated community brings to the operator,” he mentioned. The actual worth, he continued, lies in operational agility — sooner function deployment, autoscaling, and steady optimization.
He pointed to at least one U.S. operator that changed its cloud platform throughout 25,000 industrial websites in simply three months, a shift he mentioned would have been almost unimaginable in a conventional RAN setting.
