5G is evolving—are you ready?
Many organizations believe they’ve already adopted 5G, but what they’re actually using is 5G Non-Standalone (NSA)—a transitional step that still depends on 4G core infrastructure. While NSA delivers incremental gains, the real transformation comes with 5G Standalone (SA) and network slicing, which unlock the full promise of 5G: ultra-reliable, low-latency performance with dynamic resource allocation.
In addition to their technological upgrades, these capabilities are game-changers for public safety, emergency response and other mission-critical services. From enabling dedicated “slices” of the network for first responders to supporting always-on connectivity in the field, 5G SA and slicing can dramatically improve response times, situational awareness and operational coordination.
In this blog post, we’ll break down what 5G SA and network slicing are, how carriers are rolling them out, and why these advancements are so important for the future of critical communications—especially for those who can’t afford to be disconnected.
What is 5G standalone—and why does it matter?
When people hear “5G,” they often think of faster speeds. But not all 5G is created equal.
Most current 5G deployments are NSA—they rely on a 5G radio access network (RAN) combined with a legacy 4G LTE core. While NSA can improve data rates and capacity, it doesn’t deliver the full promise of 5G performance.
5G SA is the real leap forward. Unlike NSA, 5G SA introduces a completely new, cloud-native core network built for speed, scalability and ultra-low latency. This advanced architecture enables intelligent traffic routing, dynamic resource allocation and the deployment of network slices—virtual networks with dedicated performance profiles.
For emergency response teams 5G SA unlocks ultra-reliable low-latency communications (URLLC)—the kind of real-time, high-priority connectivity that can support body-worn cameras, live drone feeds, dispatch systems, and critical voice/video apps during emergency events.
While global carriers are still mid-transition, SA deployments are picking up momentum—especially in regions prioritizing critical-communication connectivity. For organizations relying on fast, fail-safe communication, staying aware of this shift is essential.
What is network slicing?
At its core, network slicing is the ability to create multiple virtual networks—each isolated and optimized for a specific purpose—within a single 5G physical infrastructure. Think of it as reserving your own dedicated lane on a digital highway.
One of the most important early use cases is public safety. With a dedicated public safety network slice, first responders can rely on guaranteed bandwidth, ultra-low latency and uninterrupted access, even when commercial networks are congested. This is the backbone of offerings like Verizon Frontline Network Slice and T-Mobile’s T-Priority, which support emergency response, disaster recovery and other high-priority communications.
Other types of network slices support diverse needs:
- Ultra-Reliable Low Latency Communication (URLLC): Supports time-sensitive operations like remote surgery, autonomous vehicles and industrial robotics.
- Massive IoT: Enables large-scale, low-power device deployments—ideal for utilities, smart cities and agriculture.
- Enhanced Mobile Broadband (eMBB): Delivers high-speed connectivity for data-heavy tasks like video streaming, teleconferencing or virtual reality.
Why it matters:
Each slice comes with its own performance guarantees, security parameters and resource allocation. This means public safety agencies, utility operators and other critical services can rely on predictable, resilient connectivity—no matter what’s happening on the broader network.
How carriers are rolling it out
Public safety is leading the charge
In the U.S., carriers like Verizon and T-Mobile are using 5G SA networks and network slicing to prioritize critical communications. Verizon Frontline and T-Mobile’s T-Priority offer first responders dedicated network access during emergencies—providing reliable connectivity during wildfires, hurricanes or mass public events, when traditional networks may be overloaded.

Selective enterprise rollouts are underway
Beyond public safety, enterprise customers are gradually introducing network slicing—especially in sectors that demand performance guarantees. Examples include:
- Logistics companies using low-latency slices for real-time tracking and autonomous vehicles.
- Hospitals leveraging slicing for secure, high-priority telemedicine applications.
- Energy providers and utilities are leveraging reliable, isolated connectivity for infrastructure monitoring.
Global momentum is building
Network slicing rollouts are accelerating globally, particularly in countries with mature 5G SA deployments. European and Asian operators have launched early slicing services, while North American carriers continue to invest in next-gen infrastructure.
As of September 2024, GSMA Intelligence reported that 57 mobile operators had launched 5G SA networks, with another 88 planning to do so—underscoring the pace of global adoption.
Why it matters for IoT and critical deployments
Not all network traffic can be treated equally. The rise of 5G SA and network slicing makes it possible to create differentiated service tiers—making sure that vital communications get through, even in moments of peak demand.
For public safety, slicing provides:
- Priority and pre-emption, giving first responders preferred access over commercial users.
- Dedicated capacity, reserving bandwidth for emergency teams—even in crowded areas or disaster zones.
- Low-latency, high-reliability connectivity, essential for push-to-talk, real-time video feeds or telemetry from drones and body cams.
Both Verizon Frontline and T-Mobile’s T-Priority are delivering these capabilities through network slicing. Verizon offers “unprecedented levels of service agility, flexibility and automated scalability” so that responder communications remain uninterrupted during emergencies. T-Mobile provides dedicated network resources with “more capacity, faster speeds, and better coverage” for public safety agencies.
IoT and enterprise applications also benefit significantly:
- Smart grid and utilities can isolate operational traffic for control systems, independent of public network load.
- Logistics and supply chain operations can maintain uninterrupted connectivity for vehicle telematics and tracking.
- Healthcare providers can allocate a secure slice for life-critical services like remote surgery or patient monitoring.
Slicing also removes contention between high-bandwidth, low-priority uses (like video streaming) and latency-sensitive operations (like emergency response apps or control systems).
As slicing becomes more widely available, organizations that plan now will be ready to take advantage of secure, isolated and predictable connectivity—future-proofing their deployments and building readiness for tomorrow’s connectivity demands.
What to look for in a 5G router
To fully benefit from 5G Standalone and network slicing, the router you choose matters. Many currently deployed routers only support NSA connectivity, meaning they can’t tap into the performance advantages of slicing.
If you’re supporting essential operations, especially in public safety, it’s important to choose a router that:
- Supports 5G SA networks—required for network slicing.
- Is certified for network slicing use by major carriers such as:
-Verizon Frontline
-T-Mobile T-Priority
- Offers SA/NSA dual compatibility, setting up a smooth transition as networks evolve.
- Enables remote configuration and monitoring, so you can adapt slices or settings as your needs change.
- Provides strong security architecture, including segmented VPNs, firewall enforcement and encryption-by-default — all essential for managing multiple virtualized network slices securely.
- Delivers future-ready firmware that evolves with your network, minimizing the need for costly hardware swaps. As highlighted in our blog —ongoing firmware support is critical for extending router life and ROI in fast-changing 5G environments.
Semtech’s AirLink® XR 5G routers—including the XR60, XR80 Gen2 and XR90 Gen2—are 5G SA-ready, certified for both Verizon Frontline Network Slice and T-Mobile’s T-Priority.

5G SA and network slicing are strategic enablers for the next generation of mission-critical connectivity. From public safety to utilities to industrial IoT, these technologies promise the performance, reliability and control that high-stakes applications demand.
Realizing these benefits requires planning. Organizations that begin evaluating 5G SA readiness now—assessing their infrastructure, upgrading their routers and understanding slicing options—will be ready to move as the ecosystem matures.
