Open RAN at Scale: How to get out of PoC and into Profitable Reality by 2026.

The discussion around Open Radio Access Network (Open RAN) has changed dramatically over the past 18 months. It is no longer in the first phase of the hype cycle, nor in the phase of disbelief in the first half of 2026. The integration of Non-Terrestrial Networks (NTN) into the broader 5G-Advanced and 6G ecosystem is no longer a futuristic experiment—it is a commercial necessity.

At Telgoo5, we see Open RAN not only as a hardware revolution, decoupling software from proprietary equipment, but also as a catalyst for its operation. For Communication Service Providers (CSPs), the realization of an open architecture means breaking out of vendor lock-in and creating a best-of-breed ecosystem. To scale this up nationally, though, requires a radical rethink of the Business Support Systems (BSS) and orchestration layers that lie behind the scenes.

The State of the Union: Open RAN in Mid-2026

The recent industry milestones in March and April 2026 have solidified Open RAN’s trajectory. Large Tier-1 operators across North America and Europe have ceased announcing localized trials and instead announced large, multi-vendor rollouts that leverage cloud-native RAN components. The call to foster silicon diversity by using chips from different vendors to avoid supply chain bottlenecks has finally matured.

Three important market forces are driving this shift, and they are:

• Energy Efficiency Mandates: As the world faces volatile energy prices, the ability to use AI-based power management in a multi-vendor RAN is now a first-order priority.
• The 5G-Advanced Push: With new capabilities from Release 18 and 19 coming online, operators must have the flexibility of programmable networks to deploy specialized slices for IoT and V2X (Vehicle-to-Everything) communication.
• Governmental Security Standards: The trend in national security requirements is shifting towards transparent, open architectures rather than so-called black-box proprietary systems.

The Complexity Paradox: Why “Open” Requires Better Management

Although Open RAN promises lower CapEx through commoditization of hardware, it presents a Complexity Paradox. With a single-vendor, traditional implementation, in the event of a failure, you have one throat to choke. In a scaled Open RAN testbed, you may have software running on a third-party cloud infrastructure by one vendor, Distributed Units (DU) by another, and Radio Units (RU) by another- all running on a third-party cloud platform.

That’s where most CSPs risk stumbling, according to the Telgoo5 POV. When your BSS and OSS (Operations Support Systems) are still in silo and manual mode, the amount of OpEx needed to handle this multi-vendor environment will soon eat any savings in CapEx realized by using cheaper hardware. To scale, the network requires an AI-native, automated framework capable of correlating data across these disparate layers in real time.

• Planning the Multi-Vendor Ecosystem.

Scaling Open RAN necessitates a complex Service Management and Orchestration (SMO) layer and a BSS sufficiently flexible to support the commercial complexities of a fragmented network.

Take, for example, the Telgoo5 application: Network Slicing as a Service. A CSP can provide a special low-latency slice to a smart factory in a scaled Open RAN environment. This slice can go through multiple different vendor RAN components. To commercialize this, the billing system must:

• Communicate with the RAN Intelligent Controller (RIC) to verify that the SLA (Service Level Agreement).
• Dynamically rate the resource consumption across different hardware footprints.
• Automate partner settlements if part of the RAN is on neutral-host infrastructure.

In the absence of a convergent, real-time charging engine such as the one we have developed at Telgoo5, scaling these advanced services becomes an administrative nightmare.

• The Role of the RIC: The “Brain” of Scaled Open RAN

The growth of the RAN Intelligent Controller (RIC) toward maturity is one of the most thrilling developments in the past few months. We are also witnessing a boom in the so-called rApps and xApps- special applications that are operating over the RIC to enable the network to perform optimally.

At Telgoo5, we observe the RIC as the nexus between network performance and business value. For example, a “Traffic Steering” xApp can identify a high-value roaming subscriber and prioritize their connection on the most efficient THz or Mid-band frequency available. Our BSS will operate in concert with these insights, enabling operators to develop packages of tiered experiences in which the network adjusts its physical parameters based on the subscriber’s real-time billing profile. That’s what Hyper-Personalization on the infrastructure level means.

• Overcoming the Integration Hurdle

The biggest challenge to scaling remains System Integration (SI). In the legacy world, the vendor did the integration. In the Open RAN world, the burden shifts to the operator or their partners.

The answer is in Standardized API Exposure. Using TMF (TM Forum) Open APIs, Telgoo5 will ensure that the BSS can communicate with any RAN component, regardless of the vendor. This ability to scale is a necessary feature of scale. An operator who is interested in adding a new RU vendor to their network in a particular region should not have to rewrite their billing logic. The BSS must merely identify the new resource and keep on processing transactions without hiccups.

Path to 2027: A Common Vision.

Open RAN is the building block as we look to 5G-Advanced and the early blueprints of 6G. The days of closed proprietary ecosystems are over because they simply cannot provide the speed-to-market that modern consumers demand.

The Open in Open RAN, however, should be more than just the radio. It needs to include a business philosophy that values data liquidity, automated workflows, and customer-oriented service design. Scaling does not merely mean adding more boxes; it is about developing a digital fabric that can grow, heal, and optimize itself.

We have years of refinement in Telgoo5 to create a platform that can succeed in these multi-vendor environments with their complexities. We know that, with a CSP, the end-point isn’t merely to have an open network–it is to have a profitable one. With the agility of Open RAN matched with the precision of real-time, AI-native BSS, operators can finally realize the full value of their spectrum investments.
