The connected airport: A pilot’s view, from runway to terminal

I’ve spent a good part of my life in airports. As a private pilot, I’ve held short of a runway while waiting for a flock of birds to clear, and I’ve flown a go-around at 300 feet because something was obstructing the runway. As a passenger, I’ve stood in an unmoving security line, watched a bag-drop kiosk reboot in front of me and sprinted to a gate that changed while I was ordering coffee.

So, when I talk about airport innovation, I don’t mean “digital transformation” in the abstract. I’m referring to problems I’ve experienced firsthand.

My conclusion: Airports don’t need to pour more concrete. They need to put more intelligence into the concrete they already have.

Solving a problem that more construction won’t fix

Most airports have a fixed number of gates and a terminal footprint that won’t change for a decade or more. Meanwhile, passenger volumes keep growing, tenants expect more and security obligations get heavier every year. You can’t fix that with construction alone — it’s slow, expensive and often blocked by land, noise and community constraints.

So, how do you get more capacity, safety and revenue out of your existing airport?

The answer is layered: a private wireless network as the foundation, one security model governing everything that connects to it, AI making the airfield visible in real time, and digital services turning all of it into revenue.

Lay the foundation: A network owned by the airport

Just like your passengers depend on you, you should be able to depend on your network. That’s the case for private wireless.

When bad weather grounds flights, thousands of passengers reach for their phones and the public cellular network can grind to a crawl. And Wi-Fi? I’ve watched technicians working below the wing lose their connection because the wing of the aircraft blocks the signal.

Private 5G gives the airport its own carrier-grade mobile network, with dedicated capacity and coverage across runways, aprons, perimeters and parking structures. It’s designed for mobility, maintaining connectivity as people and equipment move around — whether that’s a baggage vehicle crossing the apron, an autonomous mobile robot (AMR) passing through a terminal or an autonomous system operating around aircraft.

It’s also built to securely connect large numbers of devices, from cameras and sensors to scanners, vehicles and operational equipment. That combination of mobility, device density and built-in security makes private 5G particularly well suited to an airport, where thousands of connected assets may be moving between different operational environments at any given time.

Spectrum is no longer the barrier it once was. In the US, airports can use Citizens Broadband Radio Service (CBRS), Canada has opened local spectrum to private networks, and where guaranteed exclusive capacity is needed, a mobile operator can provide licensed spectrum while an integrator such as NTT DATA builds and runs the network.

In Germany, with NTT DATA’s help, Fraport AG built a private 5G network across all 2,500 hectares of Frankfurt Airport — including under those Wi-Fi-blocking wings. And Cologne Bonn Airport covered their entire 1,000-hectare campus with one of Europe’s largest fully private 5G networks, delivered as a managed service.

Improve security: Know what’s on your network

As a pilot, I trust that every system feeding me information has been maintained, inspected and signed off. Airports need the same discipline for their networks. Every new camera, sensor, tablet and autonomous vehicle is another door into the infrastructure — and if each one follows its own access rules, nobody knows what’s on the network or whether it should even be there.

The smart move is to extend the identity and access policies the airport already trusts — many run Cisco Identity Services Engine (ISE), the security policy management platform, for their enterprise network — straight into the private 5G layer. One policy engine, defined once, enforced everywhere, from an apron camera to a tablet in a patrol vehicle.

For infrastructure that touches regulated perimeters and life-safety systems, that’s the precondition for scaling with confidence.

We take the same approach at NTT DATA. In aviation, we’d never accept “We’ll add the safety systems later.” Cybersecurity deserves the same treatment: It has to be built in from the start.

Give the airport eyes on the airfield

Every pilot has a bird story. Mine is that go-around after a flock lifted off beside the runway. Go-arounds are routine, but each one is burnt fuel, a disrupted schedule and a workload spike for the crew and the controller. 

Taxiway incursions are worse: an unexpected vehicle or person is a scenario that keeps safety teams awake at night.

But when the airfield runs a private network, it becomes observable — and increasingly responsive. Vision AI continuously monitors runways, taxiways and aprons for vehicles, personnel, wildlife and foreign-object debris (FOD). Connected autonomous systems can then act on what they detect, whether that means dispatching a robot to inspect an area or alerting ground crews before a potential conflict develops. Predictive analytics can also identify patterns that signal a problem before it becomes an incident.

What if that bird activity had been detected and flagged minutes earlier? That’s not science fiction. Frankfurt is already using its network for drone-based perimeter monitoring and AI-driven FOD detection on the apron.

Passenger friction costs airports money

Back in the terminal, every point of friction I’ve experienced as a passenger is also a point of lost revenue for the airport. Time spent in a security line is time not spent in a restaurant. Anxiety about a gate change kills the appetite for browsing a shop.

Give passengers better wayfinding, live wait times, smoother check-in and boarding, self-service bag drops and real-time baggage tracking, and you give them more time — and more reason — to spend money in the terminal.

In Spain, 220 automated border-control gates in Alicante, Barcelona, Mallorca and Menorca process air passengers with facial and fingerprint biometrics. At Milan Linate, a pilot project let passengers register once on their phone and then pass security and board without ever showing a document.

The same platform serves the airport’s tenants, with demand forecasting and digital storefronts for retailers, foot-traffic analytics for leasing, retail media for advertisers, and arrival prediction for ground transport.

Turn your network into a platform for tenant services

Once an airport has built its own private 5G network, it doesn’t have to keep that connectivity to itself. The same infrastructure can become a platform for digital services offered to airlines, cargo operators, ground handlers, retailers and other affiliates across the airport.

Instead of every tenant building and securing their own patchwork of connectivity, the airport can provide reliable, managed network access wherever they operate. An airline might use it to connect ground crews and equipment across gates and aprons, or a ground handler could connect baggage systems, autonomous vehicles and AMRs as they move around the airport.

Cargo is a particularly good example. Walk any cargo apron and you’ll see tenants running serious operations on the airport’s real estate. They’re scanning shipments, tracking unit load devices (ULDs) and dollies, monitoring cold-chain pharmaceuticals, running video for remote cargo acceptance and connecting handheld devices and vehicles that constantly move between warehouse and aircraft. Yet they’re often relying on Wi-Fi that dies at the warehouse door or public cellular that’s unfit for their corner of the field.

A campus-wide private network gives the airport another option: Offer those tenants dedicated connectivity as a service. They get reliable capacity in the areas where they operate, without having to build and secure their own networks. The airport turns infrastructure it already needs into a platform for digital services — and a new source of nonaeronautical revenue.

Again, this isn’t hypothetical. Cologne Bonn, a major cargo hub, built exactly this ambition into their private 5G program: intelligent services for the cargo and logistics operations on the field, and even tenant-facing services such as smart metering of utilities. Connectivity bought for the airport’s own operations can become a service sold to the wider airport ecosystem.

As a pilot, I love this one for a less commercial reason too: An airport where vehicles, scanners, cameras and autonomous systems remain securely connected and visible as they move around the campus is also a safer airport.

How to sequence your connectivity plan

When I’m advising an airport executive team, I keep it simple:

• Prove it: Start with the highest-priority use case, usually perimeter security, and set clear performance targets and identity-based device governance from day one.
• Scale it: Add push-to-talk, fleet telemetry, gate video, airfield AI and connected autonomous systems such as baggage vehicles and AMRs to the network you’ve already justified.
• Monetize it: Add tenant connectivity, retail media, passenger services and digital-twin applications. Each phase helps fund and derisk the next.

Two things are nonnegotiable: Airports owns their data, and one partner is accountable for the network end to end. When a perimeter camera feed drops at 2am, nobody has time for three vendors pointing at one another.

Landing the concept

Through all of it, our metric for success puts people first: a ramp worker who goes home safely because a vehicle conflict was caught by a camera; a passenger who boards without stress; an air-traffic controller with one clear alert instead of six screens.

Some airports are taking the lead by making better use of what they already have — connecting it, securing it and making it more intelligent.

But networks, sensors and algorithms are only the means. People are the point.
