Why Orchestration Is the Real Test of Multi-Vendor Open RAN

Disaggregating the RAN gave operators choice. It did not make integration disappear. When a single vendor delivered the whole stack, stitching radios, baseband and software together was that vendor's problem. With Open RAN, that work now sits with the operator.

Every new site means reconciling planning inputs, parameter sets, scripts, test checks and software updates that come from different suppliers, each with its own tooling and interfaces. Integration teams have inherited a job that used to happen inside one company's walls.

At small scale, that is an inconvenience. Across a national rollout, it becomes the factor that decides how fast new capacity reaches customers and what each site costs to bring live.

Why the integration workload keeps growing

5G densification multiplies the number of sites an operator has to bring live, and each one carries stricter configuration demands. In a multi-vendor network, every extra site adds another round of cross-vendor coordination.

Well-intended fixes have often added to the strain. Many suppliers now ship their own automation and integration tooling, so operators end up running several platforms that were never designed to talk to each other. Planning, design and integration frequently live in separate systems, which means spreadsheets, manual handovers and more chances for a mismatch to slip through.

A team rolling out a few hundred sites can usually throw engineers at the problem. A team rolling out several thousand sites across, say, Ericsson and Nokia equipment cannot. Headcount stops being a lever long before the rollout plan is finished.

Who owns the outcome?

In a single-vendor world, accountability was simple. If something broke, one supplier owned the fix from end to end.

Multi-vendor RAN blurs that line. A fault can sit in an interface, a protocol implementation, a data format or a parameter mismatch, and no single supplier is contracted to own how the pieces behave together. Troubleshooting turns into a round of finger-pointing, while the operator pays for it in slipped launch dates, repeat site visits and higher operating costs.

Better contract language helps, but it does not close the gap on its own. The durable answer is for operators to take ownership of the integration layer itself, backed by automation and analytics strong enough to manage that complexity across thousands of sites.

Treating site integration as a pipeline, not a project

The operators moving fastest have stopped treating each site as a bespoke engineering job. They run integration as an automated pipeline, where people step in only at defined checkpoints.

In practice, that pipeline looks like this:

1. Intake: network requirements are pulled directly from existing planning and design systems instead of being re-keyed.
2. Build: site specifications and vendor-specific scripts are generated from version-controlled templates.
3. Validate: configurations are checked automatically against the plan before anything touches the live network.
4. Provision: sites are brought up remotely, with zero-touch steps wherever the operator's environment allows.
5. Monitor: dashboards track rollout progress, alarms and site health across every vendor, and recurring failure patterns are fed back into the templates.

Agentic AI makes this practical at scale. Engineers can start and steer workflows through a conversational interface, approve key steps, and spend their time on exceptions rather than routine configuration. The payoff is faster onboarding, fewer manual errors and rollout capacity that grows without a matching rise in headcount.

Looking ahead: AI-RAN, 6G and knowing where to automate

The integration challenge is only going to grow. As networks move toward AI-RAN and, later, 6G, operators will face more suppliers, denser grids and faster software release cycles.

The winners will not be the operators with the biggest integration departments. They will be the ones with the automation backbone to coordinate suppliers, enforce consistency and scale without friction.

Automation only pays off when it is aimed well, though. That starts with a clear picture of where engineering hours actually go, which approvals stall progress, and which manual tasks repeat site after site. Mapping those workflows first, then orchestrating them with humans kept in the loop where judgment matters, turns automation from a collection of scripts into a real change in how network operations run.
