Latest / The 5G Podcast with Fexingo: Wireless Networks, Carriers, and Mobile Infrastructure / How Network Slicing Will Change Mobile Pricing
Transcript
- Lucas: So last week I was reading through an Ericsson mobility report from April, and one number jumped out: they estimate that by 2030, network slicing could generate up to $300 billion in additional revenue for mobile operators globally. And I thought — we talk about 5G speeds and coverage all the time, but we rarely talk about how carriers actually plan to make money from it beyond just selling faster data. Luna: And network slicing is the big answer to that, right? Instead of one generic data plan, you sell guaranteed quality slices for specific use cases. Lucas: Exactly. The basic idea is that 5G networks are software-defined, so a carrier can carve out virtual 'slices' of the physical network. Each slice has its own guaranteed performance — latency, throughput, reliability. And they can charge differently for each slice. Luna: So a factory that needs 10-millisecond latency for robotic arms pays a premium, while a streaming service that can tolerate a few hundred milliseconds pays a lot less. Lucas: Right. And it's not just industrial. Think about a self-driving car fleet needing ultra-reliable low-latency slices, or a live sports broadcaster needing a guaranteed uplink slice for 4K video. Each slice is a separate revenue stream. Luna: But carriers have been promising slicing for years. What's changed in 2026 that makes it real now? Lucas: Two things. First, the 3GPP standards for 5G standalone — the full 5G core — are mature enough. Most major operators have deployed standalone 5G by now. Second, the network equipment is actually capable of it at scale. Ericsson and Nokia both have commercial slicing solutions that are being deployed in live networks. Luna: And we're seeing real deployments. Deutsche Telekom has been running slicing trials in Germany since late 2024. They partnered with a factory to provide a dedicated low-latency slice for production line robots. Lucas: I looked into that. The factory is a Bosch plant in Stuttgart. They're using a slice with a guaranteed 10-millisecond round-trip time, and Deutsche Telekom charges them per device per month — not per gigabyte. That's a fundamental shift from consumer data pricing. Luna: So it's value-based pricing instead of volume-based. If you need ultra-low latency, you pay more, even if you use very little data. Lucas: Exactly. And that changes the entire revenue model for carriers. Consumer data plans have been commoditized — unlimited plans, price wars. Network slicing lets them sell differentiated performance to enterprises, which are less price sensitive. Luna: And of course, there's the Japanese market. NTT Docomo has been aggressive with slicing for smart factories and even for drone operations. Lucas: Yeah, Docomo launched commercial slicing services in early 2025. They have a slice for drone delivery — guaranteed low latency and precise positioning. That's a slice that a company like Rakuten or a logistics firm can buy directly. Luna: It almost sounds like the carriers are becoming infrastructure as a service providers. Which is a huge shift from being just a dumb pipe. Lucas: And it's not just enterprises. Consumer applications could also see slicing. Imagine a gaming slice for cloud gaming with guaranteed low latency, or a video call slice that prioritizes your Zoom traffic during peak hours. Luna: But that raises net neutrality questions. If an operator prioritizes certain traffic, are they violating the principle of treating all data equally? Lucas: That's the big policy debate right now. In the U.S., the FCC under the current administration has been relatively hands-off, but in Europe, regulators are watching closely. The key argument from carriers is that slicing is not about prioritizing one application over another on the same slice — it's about offering different service levels for different contracts. But critics say it's still discrimination. Luna: And there's a practical challenge too. For slicing to work end to end, you need not just the radio network but also the transport network and the core to support it. That's a lot of infrastructure upgrades. Lucas: Right. Most of the slicing trials so far are limited to a single location or a single cell tower. Scaling to nationwide, multi-operator slicing is still years away. But the early results are promising. The Bosch factory in Stuttgart reported a 20% increase in production efficiency after deploying the slice. Luna: That's a real, measurable return on investment. And that's the kind of case study that convinces other manufacturers to try it. Lucas: Speaking of convincing — I want to mention something briefly. The kind of in-depth tech conversations we have on this show are only possible because listeners support us directly. A couple of dollars a month is genuinely what keeps these going — buy me a coffee dot com slash fexingo, if you've gotten something out of them. Luna: Yeah, it really does make a difference. Even the small amounts add up and let us stay independent. Lucas: Anyway, back to slicing. Another interesting area is how slicing intersects with edge computing. Luna: Right, because a low-latency slice only works if the computing is close to the user. You can't have 10-millisecond latency if the data has to travel to a centralized cloud. Lucas: Exactly. So carriers are pairing slicing with mobile edge compute nodes. AWS and Microsoft have partnerships with operators to deploy edge servers at cell sites. The slice and the edge compute are sold together as a bundle. Luna: So the factory not only gets a guaranteed latency slice, but also a local server running its AI inference models. Lucas: Right. And that bundle can be priced at a premium. Some analysts estimate that edge plus slice bundles could generate 2-3 times the revenue of a standalone connectivity plan for the same customer. Luna: That's the kind of revenue growth carriers have been chasing since 4G. So slicing might finally make 5G the profitable generation. Lucas: There's also a slice for public safety. FirstNet in the U.S. is essentially a dedicated slice for emergency services, but it's a separate network. With slicing, you could create a virtual FirstNet on a commercial network at much lower cost. Luna: That's interesting because it could make dedicated public safety networks more affordable for smaller countries or regions. Lucas: Absolutely. And one more thing — slicing enables network as a service models. A company could buy a slice for a specific event, like a music festival, and then cancel it. That's a whole new revenue stream. Luna: So the carrier becomes a flexible infrastructure provider, not just a monthly bill. Lucas: Exactly. And that's why I think network slicing is the most important 5G innovation that most people haven't heard of. It changes the business model, not just the speed. Luna: Let's watch the net neutrality debate closely, because that could shape how quickly slicing rolls out in different markets. Lucas: For sure. And we'll keep an eye on those Bosch and Docomo deployments to see if the economics actually work at scale.
