Network Slicing

Network slicing partitions a single physical network into multiple virtual networks, each tuned for specific performance, latency, or reliability requirements, all running on shared infrastructure. It depends on 5G standalone’s flexible, software-defined core, and is a key enabler of differentiated services — dedicated slices for enterprises, critical communications, or specific applications — and therefore a route to new operator revenue. In practice, slicing has advanced more slowly than early expectations, constrained by standalone deployment pace, operational complexity, and unproven demand. For operators, the question is which customers will pay for guaranteed, differentiated connectivity; for enterprises, whether a slice beats a private network. This channel tracks network slicing standards, deployments, and commercial models, with analysis of where slicing is delivering real services and where it remains a capability waiting for a market.

Tigo–Movistar Merger Reshapes Colombia Telecom

Tigo–Movistar Merger Reshapes Colombia Telecom
Colombia has cleared a milestone consolidation: Tigo has taken operational control of Movistar, creating a second national-scale incumbent to challenge Claro. The Superintendence of Industry and Commerce (SIC) approved the integration through Resolution 94169 of 2025, capping months of scrutiny and pushback from rivals and ISPs. The merger compresses Colombia’s competitive field at a time when 5G rollouts, fiber densification, and cloud-native cores demand scale. It creates a stronger counterweight to Claro, but also raises real concerns about a two-horse race and the downstream effects on MVNOs, ISPs, and enterprise buyers.

Frequently Asked Questions

What is network slicing in simple terms?
It’s the ability to carve a single physical 5G network into multiple virtual, independently configured slices, each with its own guaranteed performance characteristics for speed, latency, and reliability, so an operator can sell different service tiers off the same infrastructure rather than building separate networks for each use case. Each slice behaves, from the customer’s perspective, like a dedicated network tailored to their specific needs, even though it’s actually running on shared physical infrastructure alongside other slices serving completely different customers simultaneously. This is conceptually similar to how a single physical server can run multiple virtual machines that each behave like an independent computer, applied instead to network connectivity.
Is network slicing actually commercially available, or still experimental?
It has moved from pilot to early commercial deployment. Major carriers including T-Mobile, Verizon, Reliance Jio, and Singtel have launched commercial slicing-based offers for specific use cases, and telecom operators are described as the primary enablers of slicing technology, expected to hold roughly 62 percent of the market in 2026. That said, the industry consistently describes network slicing as being in the early stages of commercialization, meaning successful pilots are still being converted into broader, more scalable commercial offerings rather than slicing having become a fully mature, universally available product.
What’s a real-world example of network slicing in use?
Singtel partnered with Tencent Games to launch a dedicated low-latency network slice for cloud gaming in Singapore, described as the first nationwide gaming-specific network slice in the world, letting users play without downloading games or needing high-end hardware. Verizon Business launched a dedicated fixed wireless access slice for enterprise customers with guaranteed performance, extending slicing beyond mobile use cases into business broadband. Nokia and the UAE operator du were reportedly first in the industry to deploy autonomous network slicing, which automates the creation and management of slices rather than requiring extensive manual configuration.
Why does network slicing require 5G Standalone (SA)?
True dynamic, end-to-end network slicing depends on a 5G core built independently of 4G, known as 5G Standalone or SA architecture, since SA provides the flexibility and granular control needed to create, manage, and guarantee performance across multiple isolated virtual networks simultaneously. Non-standalone 5G, which still relies on a 4G core for certain control functions, can support some slicing-like capabilities but generally not with the same flexibility, automation, or end-to-end performance guarantees that SA enables. This is one of the main reasons operators have prioritized SA core upgrades specifically as a foundation for unlocking more advanced monetization opportunities like network slicing.
How big is the network slicing market expected to get?
Forecasts vary considerably depending on the specific market research firm, but most analyses put network slicing’s growth rate above 40 percent annually through the late 2020s, driven primarily by telecom operators monetizing differentiated connectivity for industries like healthcare, automotive, gaming, and manufacturing. Asia Pacific is generally described as leading global adoption given its large population base and diverse industrial use cases, while North America is often projected as the fastest-growing region given strong infrastructure investment. These projections should be treated with appropriate caution though, since the underlying market remains in an early commercialization phase.
Who actually manages and creates network slices in practice?
In practice, network slices are created and managed through orchestration software that translates a specific business requirement, such as guaranteed low latency for a particular customer’s application, into the actual technical configuration needed to deliver it across the relevant network infrastructure. This orchestration layer handles tasks like allocating the right combination of radio, transport, and core network resources to a given slice, monitoring whether it’s actually delivering its promised performance, and adjusting resource allocation dynamically as conditions change. More advanced, automated approaches, sometimes called autonomous network slicing, aim to handle much of this process automatically rather than requiring extensive manual configuration by network engineers each time.
What technical challenges have slowed broader network slicing adoption?
Several technical challenges have slowed broader adoption beyond the foundational requirement of upgrading to 5G Standalone infrastructure. Ensuring consistent performance guarantees across a slice that may span multiple different network domains, from radio access through transport and core, requires sophisticated end-to-end orchestration and assurance capabilities that have taken time to mature. Interoperability across different vendors’ equipment adds further complexity for operators running multi-vendor networks. There’s also a more fundamental business challenge: defining a manageable, scalable set of standard slice types that cover most customer needs, rather than requiring a fully custom-built slice for every individual customer, which would be operationally impractical at scale.
How is network slicing different from older approaches like VPNs or dedicated lines?
Older approaches like traditional VPNs or dedicated leased lines could provide a degree of network differentiation and security for specific customers, but they generally required separate, often physically distinct infrastructure or fixed, manually provisioned configurations that were slow and expensive to set up and change. Network slicing achieves a broadly similar goal, providing differentiated, somewhat isolated connectivity for a specific customer, but does so dynamically and through software, on top of shared underlying 5G infrastructure, without requiring separate physical infrastructure for each customer. This makes slicing considerably faster and cheaper to provision than traditional dedicated infrastructure approaches, while still providing meaningful performance guarantees and isolation.
