Latest / The 5G Podcast with Fexingo: Wireless Networks, Carriers, and Mobile Infrastructure / 5G in Logistics How Mobile Networks Are Transforming Warehouses
Transcript
- Lucas: If today's tech conversation gave you something usable, I'll get into something I've been watching closely: how 5G is quietly becoming the backbone of warehouse logistics. Luna: I've read that warehouses are testing private 5G networks, but is it really moving beyond pilot stage? Lucas: It is, and there's a specific case I want to walk through. A major European retailer — think one of the top three by revenue — deployed a private 5G network in its largest distribution center near Rotterdam back in early 2025. Luna: That's a big operational shift. What drove them to move away from Wi-Fi? Lucas: Reliability and determinism. Wi-Fi is fine for inventory scanning and voice-picking, but when you have fifty autonomous mobile robots moving pallets at high speed, even a few milliseconds of jitter can cause collisions or lost packets that stall the workflow. They needed ultra-reliable low-latency communication, and Wi-Fi 6 wasn't cutting it. Luna: So they went with a private 5G setup from one of the big infrastructure vendors. Licensed spectrum? Lucas: Right, they used the 3.7-3.8 gigahertz band, which is available for local industrial use in Europe. They deployed about a dozen small cells across a 200,000-square-meter facility, plus a local core. The total cost was around two million euros. Luna: And what kind of gains did they see? I'm guessing the ROI isn't instant. Lucas: It wasn't instant, but it came faster than expected. Over 18 months, they reported a 30 percent increase in throughput — more orders processed per shift — and a 40 percent reduction in unplanned downtime. The robots could communicate with each other and the central orchestrator with under 10 milliseconds end to end latency, 99.999 percent reliability. Luna: That reliability number is the key difference. With Wi-Fi, you might get 99.9 percent, but that extra 0.099 percent downtime adds up across hundreds of devices. Lucas: Exactly. And beyond the robots, they used the same network for real-time inventory tracking via thousands of passive IoT tags, and for predictive maintenance on conveyor systems. Vibration sensors stream data continuously, and the 5G network's quality of service slicing ensures that critical machine data isn't competing with video feeds from security cameras. Luna: Network slicing in a private network — that's something we've discussed theoretically, but here it's actually managing different traffic types on the same infrastructure. Lucas: That's the beauty of it. They have three slices: one for the robot fleet with ultra-low latency, one for IoT sensors with massive device density, and one for video and voice with high bandwidth. All on the same physical radios, but isolated logically. If the video slice gets congested, the robot slice is unaffected. Luna: That's a big step up from Wi-Fi's best-effort approach. But what about the operational complexity? Setting up a private 5G network isn't trivial. Lucas: You're right, and that's one reason adoption isn't exploding. But the vendors are making it easier. In this case, the retailer's IT team worked with a systems integrator, and after the initial deployment, they found the day-to-day management simpler than maintaining a hundred Wi-Fi access points and controllers. They actually reduced their network team by two people. Luna: And the cost per square meter? Wi-Fi is cheap per access point, but when you need dense coverage for high-reliability, the gap narrows. Lucas: That's the counterintuitive part. For a large facility, private 5G can be competitive on a total cost of ownership basis, especially when you factor in the productivity gains. This retailer's ROI was 18 percent over 18 months, which is solid for an infrastructure project. Luna: It's interesting — we've talked about 5G in manufacturing, but logistics warehousing might be where the economics click first. Lower complexity than a factory floor, but still mission-critical. Lucas: Absolutely. And we should note this isn't just about greenfield facilities. They also retrofitted an older warehouse with a private 5G overlay, and even there, they saw a 20 percent improvement in pick accuracy. Luna: Before we go deeper, I want to mention something about the show itself. We deliberately don't run ads on these episodes. It's a choice that keeps the conversation focused on what's actually happening, not on selling you something. Lucas: Yeah, and if that approach resonates, there's a simple way to support it. Buy me a coffee dot com slash fexingo — that's buy me a coffee dot com slash fexingo — and it helps us keep doing these deep dives ad-free. Luna: Right, no pressure, just an option. Back to the warehouse — what about safety? I imagine fewer collisions with that reliable connectivity. Lucas: Major improvement. They reported a 60 percent reduction in safety incidents involving robots and people. The robots have a fail-safe that requires sub-10-millisecond response from the central controller, and Wi-Fi couldn't guarantee that. With 5G, they could deploy more aggressive autonomous movements without compromising safety. Luna: So the network becomes an enabler for higher automation density. More robots per square meter, working faster. Lucas: Exactly. And this is where the operator opportunity comes in. Carriers like Deutsche Telekom and Vodafone are offering managed private 5G services specifically for logistics. They don't require the company to be a telco expert. Luna: I've seen those offerings. Some are built on network slicing of the public network, but others deploy a dedicated local core. Which approach works better for warehouses? Lucas: For now, the dedicated local core is more popular because of data sovereignty and ultra-low latency requirements. But sliced public 5G could work for smaller sites where the latency budget is a bit looser. The European retailer started with a local core and is now testing network slicing from the public network for a satellite facility. Luna: It's like they're building a hybrid model: high-reliability local for the main hub, and cost-effective sliced connectivity for smaller depots. Lucas: Right, and that hybrid model might be the blueprint for logistics companies. I think we'll see more of that in 2026 and 2027. Luna: One thing that surprises me is that we're not hearing more about this from the carriers' earnings calls. Logistics seems like a natural early adopter. Lucas: It's still early in terms of revenue contribution. But on the last call for one major European carrier, they mentioned that industrial 5G — which includes logistics — grew 45 percent year-over-year in the first quarter. It's small in absolute terms, but the trajectory is steep. Luna: So where do you see the next frontier? After warehouses, what's the next logical application? Lucas: Ports and airport logistics. Those are essentially large-scale warehouses with moving vehicles and cargo. Already, the Port of Hamburg is trialing private 5G for container handling and autonomous straddle carriers. That could be the next big case study. Luna: And that ties back to the supply chain resilience conversation. If ports can handle more throughput with fewer delays, that has macroeconomic ripple effects. Lucas: Exactly. It's not just about efficiency for one company — it's about reducing bottlenecks in global trade. That's why I think logistics might turn out to be the killer app for industrial 5G. Luna: Before we wrap, you mentioned the European retailer's ROI number. How did they measure that 18 percent? Lucas: They looked at three things: labor productivity — fewer workers needed per shift, throughput increase — more orders per hour, and reduced downtime. They used the baseline from the six months before the 5G deployment and tracked the delta. The 18 percent is the annualized return on the total project cost, including spectrum license fees. Luna: That's a compelling number for any CFO. I suspect we'll see more logistics companies doing the math. Lucas: I think so. And the technology is only getting cheaper. The small cells and local core are seeing price declines as volumes increase. By 2027, the total cost of ownership might be below Wi-Fi for new large facilities. Luna: That would be a tipping point. Then it's not just about early adopters, but mainstream adoption. Lucas: Right. And from a policy perspective, access to local spectrum is critical. Regulators in the US and Europe have already set aside bands for industrial use. If that continues, logistics could become the first vertical where 5G is the default connectivity choice. Luna: Interesting thought: default connectivity. We've been asking for years 'what is 5G for?' Maybe this is the answer. Lucas: Maybe. For now, it's worth watching the warehouse. That's where the rubber meets the road — or the robot meets the pallet.
